[0044] Many modern appliances, devices, power equipment, lighting equipment, etc. rely on electrical power for operation. Electrical power is drawn from one or more electrical power sources. Access to such power sources is typically provided using various wiring devices that may be mounted to and / or in an electrical box (mounted in any suitable location) connected to an electrical power source. Non-limiting examples of such wiring devices include switches, outlets, universal serial bus (USB) ports (e.g., Type A, TypeB, Type-C, Mini-A, Mini-B, Micro- A, Micro- B, or any other suitable form, etc.), circuit interrupters, lighting controls, fan speed controls, dimmers, occupancy sensors, heating ventilation air conditioning (HVAC) equipment / controllers, etc. Circuit interrupters may, for example, include ground fault circuit interrupters (GFCIs), arc fault circuit interrupters (AFCIs), resettable circuit interrupting device, immersion detection circuit interrupter (IDCIs), appliance leakage circuit breaker (ALCIs), latching interrupting devices, contactor, and overcurrent devices. Additionally, any suitable combinations of these devices can be integrated into a single wiring device (e.g., a combo device such as a combo GFCI / AFCI). Switches may include a load control device such as a toggle / paddle switch, a dimmer switch, etc. and can be used to control one or more loads, such as, a lighting load or a motor load, e.g., a fan. Outlets may include, e.g., electrical power outlets, data cable outlets, satellite / cable television outlets, security video outlets, adapters, splitters, transformers, etc. Some outlets provide alternating current (AC) to AC powered devices as well as to devices which first convert / transform the AC power to direct current (DC) or some other AC voltage / frequency via an external internal transformer.

[0045] Further, to provide an electrical connection to an appliance, equipment, device, etc., a plug coupled (e.g., permanently and / or temporarily) to the appliance using a wire or a flexible cord, is connected to an outlet disposed in a receptacle (e.g., a wiring device that includes one or more outlets that can receive a plug) that is typically fixed on a wall (e.g., a wall of a house, a building, etc.). Alternatively, or in addition, the plug may be connected to a piece of power equipment (e.g., a power generator). A typical plug includes a male connector and two or more protruding blades and / or pins that match openings / apertures and female contacts in an outlet of the receptacle. Typically, a plug will have a phase blade, a neutral blade, and a ground pin. Similarly, male connectors has corresponding female contacts and are typically fitted to an end of a flexible cord.

[0046] The receptacles connect electrical equipment to an AC power source or line voltages in residential houses, commercial buildings, factories, etc. A line voltage is supplied to buildings / residences (e.g., electric light and power), for example, 110 VAC, 115 VAC, 120 VAC, 125 VAC, 208 VAC, 220 VAC, 230 VAC, 240 VAC, single or multiphase. Such line voltage is typically made available to the end user standard plug / outlet configurations standardized by the National Electrical Manufacturers' Association (NEMA) configurations. One such standardized configuration is a NEMA 5-15 configuration which denotes a nominal 125 VAC / 15 Amp outlet.

[0047] Some appliances, devices, equipment, etc. may require use of a low voltage. A low voltage refers to a voltage which is less than a certain threshold (50 Volts for example, AC or DC). This reduced voltage is typically used for communication, signaling, data / multimedia transmission, low voltage charging, and the like. For the purposes of the present application, the term low voltage also includes optical transmission (although no electrical voltage is actually transmitted by optical transmission).

[0048] Low voltage ports or cables denote any suitable type of communication or telecommunication low voltage ports or cables, such as, but not limited, to Universal Serial Bus (USB), Audio / Video / Multimedia, Digital Visual Interface (DVI), Ethernet / data (e.g., copper, RJ- 45), High Definition Multimedia Interface (HDMI), IEEE 1394 (FireWire), Thunderbolt, Separate Video (S-Video), Video Graphics Array (VGA), coaxial (coax; F connector), headphone cords, telephone, or any suitable combination thereof. For the purposes of this application, low voltage ports can also include fiber optic ports (although no electrical voltage is actually transmitted by fiber optic ports).

[0049] Further, some appliances, devices, equipment, etc. may require different types of electrical plugs and receptacles, where such plugs / receptacles may vary in voltage, current rating, shape, size, connector types, etc. in accordance with various standard systems of plugs and receptacles around the world. As stated above, a typical receptacle includes one or more outlets, with each outlet having female electrical contacts that are configured to mate with male blades / prongs of a plug. There are different types of receptacles, such as, for example, decorator receptacles (e.g., having a rectangular front face with dimensions not typically exceeding 1.3 inch by 2.62 inch), duplex receptacles (e.g., having two outlet portions where each outlet portion has the shape of a circle with two equal circular segments removed, the circle having a radius not typically exceeding 1.327 inch), and / or any other types and / or configurations of receptacles.

[0050] Further, a typical wiring device is fitted with and / or covered by a wall plate. In addition to serving as a decorative piece, the wall plate covers wiring of an energized circuit of the wiring device, thereby protecting end users from contact with electrical wiring and / or other internal components of the wiring device and mitigating an electrical shock hazard.

[0051] Moreover, to protect users from electrical shock, receptacle openings are shaped to prevent finger contact with live electrical wiring and / or other electrical components of a wiring device. For example, socket contacts are typically recessed behind receptacle openings, where blades of the plugs mate with female contacts and fit closely within the recessed receptacle openings to further reduce the risk of user’s finger accidentally contacting live electrical pins. In some cases, contact pins blades include insulation over at least a portion of their length. This further reduces exposure of energized metallic parts during plugging / unplugging of plugs into / out of the outlets. Additionally, some outlets include tamper resistant (TR) shutters or sliders (terms used interchangeably herein without the intent to limit or distinguish) to stop foreign objects from being inserted into energized contacts.

[0052] However, existing wiring devices are not able to provide interchangeable inserts or modules (terms used interchangeably herein without the intent to limit or distinguish) for positioning in such devices to allow for enhanced and / or different functionalities (e.g., interchangeable modules to enable easier replacement and / or changing of functionality).

[0053] As will be described herein, in some implementations, the present disclosure relates to electrical systems that include one or more wiring devices that include a base unit having one or more cavities configured to receive one or more removable modules to provide different, additional, and / or enhanced functionalities to the wiring device without altering and / or replacing internal wirings of the base unit of the wiring device. In use, the base unit of the wiring device may be electrically wired to a source of electrical power (e.g., AC power). In addition, and / or alternatively, in some implementations, the base unit may include one or more built-in functionalities such as, for example, an electrical outlet, an on / off switch, a network outlet, etc.

[0054] By way of a non-limiting example, the base unit of the wiring device may be configured as an on / off switch, an electrical receptacle / outlet (and / or any other type of electrical device), and / or any other type of wiring device. Such wiring device may be enhanced, upgraded, substituted, etc. with further functionalities, without removing / replacing the base unit wiring from its installation location (e.g., a wall), and / or requiring services of a professional (e.g., an electrician), and / or an end-user (e.g., a homeowner) doing work with AC wiring. Some nonlimiting examples of such enhancements, upgrades, substitutions, etc. may include: a dimming module (which, for example, may upgrade the on / off switch into a dimmer switch); a smart switch / dimmer module (which, for example, may upgrade the on / off switch to a network connected switch / dimmer capable of remote / smart control); an occupancy sensor- switch / occupancy sensor-dimmer module (which, may, for example, upgrade the on / off switch to a occupancy / vacancy sensor-switch / dimmer controlled device); a networked voice-control switch / dimmer module (which may, for example, upgrade the on / off switch to a voice / intelligent- assistant (AlexaTM, SiriTM, GoogleTM, Bixby TM, etc.) controlled switch / dimmer); as well as any other modules that may be configured to include one or more different, enhanced, advanced, and / or any other types of functionalities. As can be understood, the wiring devices may be configured as any other types of units and / or devices having one or more functionalities (e.g., network switches, light switches, etc.).

[0055] Moreover, in some implementations, the wiring devices may be configured to have a first functionality (e.g., an on / off switch, etc.) and may be configured to receive one or more modules having multiple second functionalities that may be same and / or different as the first functionality (e.g., on / off switch, dimmer switch, network switch, etc.). As can be understood, any single- and / or multiple-functionality modules may be added to any single- and / or multiple-functionality wiring devices. In some implementations, wiring devices may be configured as simple electrical “boxes” without being assigned any specific functionality and one or more modules may be added to provide a specific desired functionality.

[0056] FIG. 1 illustrates a perspective view of an exemplary illustrative implementation of a wiring device 100. As shown, the wiring device 100 includes a base unit 102 and one or more removable inserts or modules 104 (terms used interchangeably herein without the intent to limit or distinguish). In addition, the wiring device 100 includes a coupling mechanism for securing the removable module 104 to the base unit 102. In use, while a particular coupling mechanism is shown and will be described, the coupling mechanism may be any suitable coupling mechanism for coupling the removable module 104 to the base unit 102 now known or hereafter developed. Thus, for purposes of the present disclosure, the wiring device 100 should not be limited to any specific coupling mechanism unless specifically claimed.

[0057] As generally shown in the exemplary implementation of FIG. 1, the base unit 102 may include a housing having a front portion, a rear wall, a top wall, a bottom wall, and two side walls. As such, the housing may, for example, be shaped as a box, a cube, a parallelepiped, etc. As can be understood, any desired shape of the housing is possible. In addition, as shown, the base unit 102 may also include an interior cavity 114 that may be partially enclosed by the walls of the housing. The front portion may be substantially opened and may be configured to allow insertion (and subsequent securing) of the removable module 104 into the interior cavity 114 of the base unit 102.

[0058] In use, the base unit 102 of the wiring device 100 may be coupled to an electrical box (not shown in FIG. 1) that may, in turn, for example, be mounted to a wall, a ceiling, and / or any other desired location. In addition, and / or alternatively, the base unit 102 may be connected toan AC power source. In addition, as will be described in greater detail below, the base unit 102 may include one or more electrical contacts or terminals 116 (terms used interchangeably herein without the intent to limit or distinguish) positioned therein. In use, the electrical contacts or terminals 116 are sized and configured to receive one or more terminal contacts, terminals, blades, or contacts 118 (terms used interchangeably herein without the intent to limit or distinguish) extending from the module 104. The electrical contacts or terminals 116 of the base unit 102 being used to provide electrical connection, and thus electrical power, to the removable module 104 once the module 104 has been fully coupled to the base unit 102 of the wiring device 100 (e.g., the removable module 204 includes one or more terminal contacts 118 configured to interact and / or electrically couple to one or more electrical contacts or terminals 116 located in the base unit 102).

[0059] That is, with reference to exemplary implementation of the wiring device shown in FIG. 1, the base unit 102 of the wiring device 100 includes a cavity 114 used for positioning and securing of a removable module 104 (shown as a removable electrical outlet / receptacle 104a). The cavity 114 may be appropriately sized to accommodate such positioning / securing. The wiring device 100 may also include a second receptacle 104b. In some implementations, the second receptacle 104b may be configured to be integral (e.g., not removable) with the base unit 102 of the wiring device 100 and may be disposed adjacent to the cavity 114 (e.g., above the cavity 114 as shown in FIG. 1, although this is but one configuration and others are envisioned such as below or to the side). Alternatively, in some implementations, the second receptacle 104b may be removable similar to the first receptable 104a and may be received within the cavity 114, or a second cavity formed in the base unit 102 of the wiring device 100, which may be disposed adjacent to the cavity 114. The receptacle 104b may be configured to provide electrical connection to one or more appliances, devices, equipment, etc. when such appliances, devices, equipment, etc.are plugged into the receptacles. Once secured inside the cavity 114, assuming the removable module 104 is another outlet 104a, it may also be configured to provide electrical connection to one or more appliances, devices, equipment, etc. upon plugging such appliances, devices, equipment, etc. into the removable module 104. As can be understood, the second receptacle may be configured to provide any other functionality such as, for example, an on / off switch. As also can be understood, the removable module 104 may be configured to provide any other functionality.

[0060] As shown in the illustrated implementation, the second receptacle 104b may be configured to include electrical contact apertures or openings 106 (d, e, f). The contact apertures or openings (terms used interchangeably herein without the intent to limit or distinguish) of the receptacle 104b may be configured to provide access to female electrical contacts that may be configured to mate with male electrical blades or prongs of a plug of an appliance, device, equipment, etc. when a plug is plugged into the receptacle. Assuming removable module 104 is another outlet 104a, as shown in FIG. 1, it may include electrical contact apertures 106 (a, b, c) that may be used for connecting an electrical plug. Otherwise, the removable module 104 may provide any other desired functionality once secured inside the cavity 114.

[0061] The wiring device 100 may also be covered by a wall plate 102 that may provide protection (as well as serve a decorative purpose) to the end user from electrical components of the wiring device 100. For simplicity and ease of illustration only, various internal components, such as, electrical wiring, connections to electrical power source, structural mounting components (e g., mounting straps, screws, etc.), etc. are not shown in FIG. 1. Such electrical wiring and / or connections may be disposed in or proximate to a rear portion 108 of the wiring device 100 and may be connected to the outlet box (not shown in FIG. 1).

[0062] As stated above and as shown in FIG. 1, the removable module 104 may be removably secured within the cavity 114 of the base unit 102, where such removable securing allows adding, enhancing, upgrading, changing, etc. one or more functionalities of the wiring device 100. For example, instead of being another electrical outlet, the removable module 104 may be configured as a dimmer switch, thereby adding a dimmer switch functionality to the wiring device 100. This results in the wiring device 100 having two functionalities: an electrical outlet (as provided by the receptacle 104b) capable of receiving plugs of various electrical devices, appliances, equipment, etc. and a dimmer switch. In an alternate implementation, the removable module 104 may be configured as a network port (e.g., a USB / data port), thereby adding a network functionality to the wiring device 100 allowing it to have an electrical outlet functionality (again, as provided by the receptacle 104b) and a network functionality. As can be understood, any other desired functionalities may be provided by the removable module 104 to the wiring device 100. The ability to swap out removable module 104 in the wiring device 100 allows the end user to quickly add, enhance, upgrade, change, etc. one or more functionalities of the device 100 without opening the device 100 (e.g., rewiring the base unit 102 of the wiring device 100 to electrical power source) and accessing its internal components, thus, mitigating possibility of electrical shock.

[0063] As previously mentioned, to provide electrical connection to the removable module 104, the cavity 114 may include one or more electrical contacts or terminals 116, which are configured to mate with one or more terminal contacts 118 of the removable module 104. By way of a non-limiting example, the terminal contacts 118 can be male blades and the electrical contacts or terminals 116 can be female contacts. The electrical contacts or terminals 116 can be electrically connected to electrical power source (not shown in FIG. 1) via electrical wiring.

[0064] Upon being inserted into the cavity 114, the removable module 104 may be secured within the cavity 114 using any suitable coupling mechanism. By way of a non-limiting example, as shown in FIG. 1, a latch 110 that may be pivotally mounted on a top surface of the removable module 104 using pivotal connection 112. The latch 110 may be configured to interact with a pin 120 disposed within the cavity 114 of the wiring device 100. The pin 120 may be configured to be mounted on the top surface of the cavity 114 and project in a downward direction from a top surface of the cavity 114. Upon insertion of the removable module 104 into the cavity 114, the latch 110 can be rotated about the pivotal connection 112 in a first direction (e.g., clockwise) so that the latch 110 can engage the pin 120 and lock the removable module 104 inside the cavity 114. To remove the removable module 104 from the cavity 114, the latch 110 can be rotated in a second direction (e.g., counterclockwise), thereby releasing or disengaging from the pin 120 and unlocking (the removable module 104 from inside the cavity 114), allowing its removal. As can be understood, any other ways of securing / removing the removable module 104 in / from the cavity 114 are possible.

[0065] As stated above, once the coupling mechanism is released, the removable module 104 can be pulled away or removed from the interior cavity 114 of the base unit 102. While pulling or removing the removable module 104, the terminal contacts 118 of the removable module 104 become disengaged from the electrical contacts or terminals 116, allowing the removable module 104 to be completely removed from the interior cavity 114 of the base unit 102.

[0066] To secure the removable module 104 inside of the interior cavity 114 of the base unit 102, the removable module 104 is aligned with and inserted into the interior cavity 114. Thereafter, the coupling mechanism may be utilized to secure the removeable module 104 within the interior cavity 114 of the base unit 102. With the removable module 104 coupled to the baseunit 102, the terminal contacts 118 of the removable module 104 are engage, in contact with, interact with, etc. the electrical contacts or terminals 116 of the base unit 102 to provide electrical connection to the removable module 104.

[0067] Further information related to structure and / or operation of wiring devices and / or base units can be found in the International Patent Appl. No. PCT / US24 / 19839, filed March 14, 2024, which is a non-provisional of, and claims the benefit of the filing date of, U.S. Patent Provisional Patent Application No. 63 / 453,783 to Teoh et al., filed on March 22, 2023, and entitled “Separable Components in Wiring Devices”, and U.S. Patent Application No. 63 / 527,453 to Ambos et al., filed July 18, 2023, entitled “Modular Wiring Devices, Systems, and Methods,” the entireties of which applications are incorporated by reference herein.

[0068] In some implementations, the current subject matter relates to an electrical system that provides wiring of various electrical and / or electronic components. The system may include one or more base units (e.g., base units 102 shown in FIG. 1) that are electrically connected to a source of an electrical current (e.g., a line). The base units may include one or more base unit terminals (e.g., line phase, line neutral, load phase, load neutral, ground). The base units may also include one or more switches that have an open state and a closed state.

[0069] The system may also include one or more removable modules (e.g., removable module 104 shown in FIG. 1). The removable modules may include one or more removable module terminals (e.g., line phase, line neutral, load phase, load neutral, ground). The removable modules may electrically couple to the base units. Upon coupling of the removable modules and the base units, the base unit terminals electrically couple to the removable module terminals (e.g., insertion of the removable module into the base unit connects terminals).

[0070] The base units may include one or more connectors and / or connection switches (hereinafter, “connectors”) electrically connecting the source of the electrical current passing through the base units to one or more switches. The removable modules may include one or more breakers, breaker members, projections, and / or actuators (hereinafter, “breaker(s)”) that may be configured to break, interrupt, disconnect, etc. such connectors (whether temporarily and / or permanently). Upon coupling of the removable modules and the base units, the breakers disconnect the connectors and thereby disconnect the source of the electrical current from at least the switches (as can be understood, power may still be connected to one or more contacts in either the base unit and / or the removable module). Upon breakers disconnecting the connectors and switching the switches into the closed state, the source of the electrical current is connected to the removable modules to provide electrical current to the removable modules using the electrically coupled base unit and removable module terminals. In some implementations, the base unit switches may be arranged and / or configured to directly switch power on / off in the base unit. Alternatively, or in addition, such base unit switch simply be arranged and configured as inputs to another electronic component(s), such as, for example, but not limited to, circuit(s), microprocessor s), etc. In the latter case, the state of the base unit switch(es) might not necessarily have to be concordant with a particular resulting connection (e.g., an open switch may cause current to be supplied to the base and / or the removable module).

[0071] In some implementations, upon switching the base unit switches into the open state, the source of the electrical current may be disconnected from the removable modules. The switches may include at least one of the following: a mechanical switch, an electrical switch, an electromechanical switch, a digital switch, a microswitch, a relay, and / or any other types of switches, and / or any combination of switches.

[0072] In some implementations, the removable modules may include one or more different types of electronic components. The electronic components, upon the breakers disconnecting the connectors and switching the switches into the closed state, may be connected to the source of electrical current. The electronic components may include various switching modules or components, which may include module(s) that do not have a capability to switch and / or control a load, which, for ease of description only, may be referred to as type 1 modules or components.

[0073] Type 1 components may be incorporated into and / or be arranged and configured as receptacle base unit(s) (with and / or without receptacle base unit compatible removable modules). Such base units supply power to a removable module, where the removable module may be wired to the load. While the removable module may include a power switch, the base unit does not include a power switch. A power switch and / or switching may refer to controlling an actual load current (e.g., on, off, bright, dim, etc.). Examples of such base units and compatible removable modules are shown in FIGS. 8a-d. Removable modules may include a blank removable module (as shown in FIG. 8a), a receptacle removable module (as shown in FIG. 8b), a USB removable module (as shown in FIG. 8c), a guidelight removable module (as shown in FIG. 8d), and / or any other removable modules.

[0074] In some embodiments, the electronic components may also include switching modules that have a capability to switch and / or control a load, where the current to the load through the module may be pulled from a switching terminal. A switch in the base unit may also carry the load current and may also directly switch the load. These switching modules may, for ease of description only, also be referred to as type 2 modules or components.

[0075] Type 2 components may be incorporated into and / or be arranged and configured as single-pole base unit(s) wired to the load (where the load is not wired to the removable module). The base unit may include a power switch. The removable module may also include a power switch. The base unit and / or removable module may cooperate to switch power to the load. Power to the load may be switched at a single location. Examples of such base units and compatible removable modules are shown in FIGS. 9a-h. Removable modules may include a blank removable module (as shown in FIG. 9a), a receptacle removable module (as shown in FIG. 9b), a USB removable module (as shown in FIG. 9c), a guidelight removable module (as shown in FIG. 9d), a dimmer (as shown in FIG. 9e), a smart dimmer (as shown in FIG. 9f), a smart switch (as shown in FIG. 9g), an occupancy sensor (as shown in FIG. 9h), and / or any other removable module.

[0076] In some embodiments, the electronic components may further include switching modules that have a capability to switch or control the load, where the current to the load through the module is pulled from the LINE terminal. In this case, the switch in the base unit does not carry the load current and cannot directly control the load. Instead, the switch in the base unit acts as an input to the switching module, signaling the module to switch the load. These switching modules may, for ease of description only, be referred to as type 3 modules or components.

[0077] Type 3 components may be incorporated into and / or be arranged and configured as multi-way base unit(s). These are similar to the single-pole switch base unit(s) except that a plurality of base units may each include a power switch and a plurality of power switches may cooperate to switch power to the load from a plurality of locations. Examples of such base units and compatible removable modules are shown in FIGS. lOa-h. Removable modules may include a blank removable module (as shown in FIG. 10a), a receptacle removable module (as shown in FIG. 10b), a USB removable module (as shown in FIG. 10c), a guidelight removable module (asshown in FIG. lOd), a dimmer (as shown in FIG. lOe), a smart dimmer (as shown in FIG. lOf), a smart switch (as shown in FIG. 10g), an occupancy sensor (as shown in FIG. lOh), and / or any other removable modules.

[0078] In some embodiments, the switching components may be arranged and configured as multi-way companion base unit(s). Such base unit(s) may allow for communication with one or more single-pole and / or multi-way switch base unit(s). Power switching does not occur within the multi-way companion base unit. Examples of such base units and compatible removable modules are shown in FIGS. 1 la-e. Removable modules may include a blank removable module (as shown in FIG. I la), a receptacle removable module (as shown in FIG. 11b), a USB removable module (as shown in FIG. 11c), a guidelight removable module (as shown in FIG. l id), an occupancy sensor (as shown in FIG. l ie), and / or any other removable modules.

[0079] In some example, non-limiting implementations, the removable modules may include type 2 components electrically connected to a TRIAC (and / or any other controllably conductive switch(es)). The type 2 components, upon the breakers disconnecting the connectors and switching the switches into the closed state, may be connected to the source of electrical current via the TRIAC .

[0080] Alternatively, or in addition, the removable modules may include type 3 components electrically connected to the TRIAC, where the TRIAC may be electrically connected to a relay switch. The type 3 components, upon the breakers disconnecting the connectors and switching the switches into the closed state and closing the relay switch, may be connected to the source of electrical current via the TRIAC.

[0081] In some implementations, the base units may include at least one of the following: receptacle base unit(s), single-pole base unit(s), multi-way base unit(s), companion multi-way baseunit(s), and / or any other types of base units, and / or any combination thereof. The multi-way base units may include a traveler connection for electrically connecting the multi-way base units to at least one of: another single-pole base units, another multi-way base units, and / or any combination thereof. The base unit terminals may include traveler connection base unit terminals. The traveler connection base unit terminals may be electrically coupled to multi-way electronic components disposed in the multi-way base units. The multi-way electronic components may control electrical connection between multi-way base units and at least one of: another single-pole base units, another multi-way base units, companion multi-way base units, and / or any combination thereof. Further, the removable module terminals may include traveler connection removable module terminals. The traveler connection removable module terminals may be electrically coupled to type 3 components in the removable modules. Upon coupling of the removable modules and the base units, traveler connection base unit terminals may electrically couple to the traveler connection removable module terminals. In some embodiments, the traveler connection may include a line voltage, a low voltage, and / or any other connection. It may also be arranged and configured as a programmable logic control, and / or implement any other desired protocol. An example of a control system is disclosed in the co-owned U.S. Patent No. 7,683,755, entitled “Control System for Electrical Devices,” the disclosure of which is incorporated herein by reference in its entirety.

[0082] In some implementations, uncoupling of the removable modules from the base units may create an air gap between the base unit terminals and the removable module terminals.

[0083] In some implementations, the current subject matter relates to an electrical system that may include one or more base units electrically connected to a source of electrical current (e g., line). The base units may include base unit terminals (e.g., line phase, line neutral, load phase, load neutral, ground) and one or more switches having an open state and a closed state. The systemmay also include one or more removable modules having removable module terminals (e.g., line phase, line neutral, load phase, load neutral, ground). The removable modules may electrically couple to the base units. Upon coupling of the removable modules and the base units, the base unit terminals electrically couple to the removable module terminals. Upon switching the switches into the closed state, the source of electrical current may be directly connected to the removable modules to provide electrical current to the removable modules using the electrically coupled base unit terminals and the removable module terminals. The source of electrical current may be directly connected to the removable modules using one or more low-resistance electrical paths (e.g., a shunt).

[0084] In some implementations, the current subject matter relates to an electrical base unit that may be electrically connected to a source of electrical current (e.g., line) and configured to electrically connect to one or more removable modules. The electrical base unit may include one or more base unit terminals and one or more switches having an open state and a closed state. The base unit may include one or more connectors electrically connecting the source of the electrical current to the switches. The base unit terminals may be configured for electrical connection to removable module terminals of the removable modules upon coupling of the removable modules and the electrical base unit. Upon disconnecting the connectors and switching the switches into the closed state, the source of the electrical current may be connected to the removable modules to thereby provide electrical current to the removable modules using the electrically coupled base unit terminals and the removable module terminals.

[0085] In some implementations, the removable modules may include breakers that disconnect the connectors to thereby disconnect the source of the electrical current from the switches. Upon switching the switches into the open state, the source of the electrical current maybe disconnected from the removable modules. The switches may include at least one of the following: a mechanical switch, an electrical switch, an electro-mechanical switch, a digital switch, a relay, and any combination thereof. The electrical base unit may include at least one of the following: a receptacle base unit, a single-pole base unit, a multi-way base unit, a companion multi-way base unit, and / or any combination thereof. The multi-way base unit may include a traveler connection for electrically connecting the multi-way base unit to at least one of: another receptacle base unit(s), another single-pole base unit(s), another multi-way base unit(s), another companion multi-way base unit(s), and / or any other type of base unit(s), and / or any combination thereof.

[0086] As stated above, the base unit terminals may include traveler connection base unit terminals. The traveler connection base unit terminals may be electrically coupled to multi-way electronic components disposed in the multi-way base unit. The multi-way electronic components may control electrical connection between the multi-way base unit and at least one of: another receptacle base unit(s), another single-pole base unit(s), another multi-way base unit(s), another companion multi-way base unit(s), and / or any other type of base unit(s), and / or any combination thereof. The removable module terminals may include traveler connection removable module terminals. The traveler connection removable module terminals may be electrically coupled to type 3 components in the removable modules. Upon coupling of the removable modules and the electrical base unit, traveler connection base unit terminals electrically couple to the traveler connection removable module terminals. In some implementations, uncoupling of the removable modules from the electrical base units creates an air gap between the base unit terminals and the removable module terminals.

[0087] In some implementations, the current subject matter relates to an electrical removable module configured for an electrical connection to an electrical base unit electrically connected to a source of electrical current. The removable module may include one or more removable module terminals, where, upon coupling of the electrical removable module and the electrical base unit, removable module terminals may electrically couple to base unit terminals. The removable module may include one or more electronic components being configured to be electrically connectable to the source of electrical current upon electrically connecting of the electrical removable module and the electrical base unit. The removable module may include one or more breakers. Upon coupling of the electrical removable module and the electrical base unit, the breakers may disconnect connectors of the electrical base unit to thereby disconnect the source of the electrical current from switches of the electrical base unit. Upon the breakers disconnecting the connectors and switching the switches into the closed state, the source of the electrical current may be electrically connected to the electronic components to thereby provide electrical current to the electronic components using the electrically coupled base unit terminals and the removable module terminals. The electronic components may include at least one of the following: type 1 components, type 2 components, type 3 components, and / or any combination thereof. The type 2 components may be electrically connected to a TRIAC disposed in the removable module. The type 2 components, upon the breakers disconnecting the connectors and switching the switches into the closed state, may be connected to the source of electrical current via the TRIAC.

[0088] Alternatively, or in addition, the type 3 components may be electrically connected to the TRIAC. The TRIAC may be electrically connected to a relay switch. The type 3 components, upon the breakers disconnecting the connectors and switching the switches into the closed state and closing the relay switch, may be connected to the source of electrical current via the TRIAC.The base unit terminals may include traveler connection base unit terminals that may be electrically coupled to multi-way electronic components disposed in the electrical base unit. The multi-way electronic components controlling electrical connection between the electrical base unit and at least one of: another single switch base units, another multi-way switch base units, and / or any combination thereof. The removable module terminals may include traveler connection removable module terminals that may be electrically coupled to type 3 components in the electrical removable module. Upon coupling of the electrical removable module and the electrical base unit, traveler connection base unit terminals may electrically couple to the traveler connection removable module terminals. Uncoupling of the electrical removable module from the electrical base unit may create an air gap between the base unit terminals and the removable module terminals.

[0089] In some implementations, the current subject matter relates to a wall-box mounted wiring device that may be disposed in a premise (e.g., a room, a house, a building, a warehouse, etc.). The wiring device may include a housing that may include an interior cavity structured to removably receive a removable module (e.g., that may be selected from a plurality of modules). The housing may also include one or more or a plurality of conductive paths that may be structured to be placed in electrical communication with premise’s AC wiring. The conductive paths may include a line phase conductive path structured to be in electrical communication with an AC power source (e.g., source of electrical current), a load phase conductive path structured to selectively place the AC power source in electrical communication with an electrical load, a neutral conductive path, and a ground conductive path. As can be understood, other conductive (or non- conductive) paths may also be included in the housing. Moreover, other designations of these paths may be used. Each conductive path may include a wiring terminal structured to be connected tothe premise’s AC wiring and a base unit terminal, which may at least partially be disposed within the interior cavity and in electrical communication with the wiring terminal.

[0090] The housing may also include a power switch that may at least be partially disposed within the housing. The power switch may include a first contact in electrical communication with the line phase conductive path, a second contact, and be characterized by an open state and a closed state.

[0091] The wiring device may further include a base unit switch output terminal in electrical communication with the second contact of the power switch. The base unit switch output terminal may at least be partially disposed within the interior cavity.

[0092] In some implementations, an opening that may be arranged and configured at a predetermined location within the interior cavity of the housing. The opening may be structured to receive a single corresponding actuation projection disposed on the removable module. The single corresponding actuation projection may be electrically non-conductive. The interior cavity is not capable of receiving a removable module having a single corresponding actuation projection at more than one location.

[0093] The wiring device may also include an actuator (e.g., accessible by a user when the housing is mounted within a wall-box), which may be arranged and structured to actuate the power switch between the open state and the closed state. The wiring device may also include a redirect switch that may include a first contact in electrical communication with the load phase conductive path, a second contact in electrical communication with the second contact of the power switch, and that may be characterized by an open state and a closed state. The redirect switch may be structured to be in the closed state when the removable module received in the interior cavity of the housing does not include an actuation projection or there is no removable module received inthe interior cavity. The redirect switch may be structured to be in the open state when the removable module received in the interior cavity includes the single corresponding actuation projection.

[0094] In some implementations, the wiring device may include a drive circuitry in electrical communication with the power switch. The power switch may be a relay. The actuator may be structured to energize the drive circuitry. Upon energization of the drive circuitry, the drive circuitry may be structured to transition the power switch to the open state or the closed state.

[0095] In some implementations, the current subject matter relates to a removable module. The removable module may include a housing sized and structured to be removably inserted at least partially into an interior cavity of a wall-box mounted wiring device. The housing of the removable module may include a plurality of conductive paths. The conductive paths may include a line phase conductive path structured to be placed into electrical communication with an AC power source (e.g., source of electrical current) when the housing is inserted at least partially into an interior cavity of the wall-box mounted wiring device, a load phase conductive path structured to selectively place an AC power source in electrical communication with an electrical load, and a neutral conductive path. Each path may include a module terminal arranged and structured to establish electrical communication with a base unit terminal in an interior cavity.

[0096] The removable module may also include a power switch at least partially positioned within the housing. The power switch may be arranged in series electrical connection between the line phase conductive path and the load phase conductive path. The power switch may be structured to selectively establish an electrical connection between the line phase conductive path and the load phase conductive path.

[0097] The removable modules may further include a single actuation projection. The projection may be electrically non-conductive and arranged at a predetermined location of the housing. The projection may further be sized and structured to actuate a redirect switch of the wallbox mounted wiring device. Actuation of the redirect switch may cause power to be redirected to flow through the line phase conductive path to the load phase conductive path when the housing is received into the interior cavity. The removable module does not include a plurality of actuation projections.

[0098] FIGS. 2a-b illustrate examples of systems for electrically wiring one or more wiring devices and one or more base units, according to some implementations of the current subject matter. FIG. 2a illustrates an example electrical wiring system 250a having a shunt 211, and FIG. 2b illustrates an example electrical wiring system 250b having a connector 212. The systems 250a and 250b may be configured to include single-pole base units and removable modules having type 1 electronic components, as discussed above.

[0099] Referring to FIG. 2a, the system 250a may include a base unit 202a and a removable module 204a. The base unit 202a may be connectable to an external electrical circuit, e.g., an electrical main (not shown in FIG. 2a) and may include one or more terminals and / or connectors (hereinafter, “terminals”) that may be arranged and configured to one or more external circuit wires as well as one or more terminals that may be arranged and configured to one or more terminals of the removable module 204a. The terminals may include a male terminal and / or a female terminal, such as, for instance, the base unit may include a male terminal and the removable module may include a corresponding female terminal, so that, upon coupling of the base unit and the removable module (as, for example, shown in FIG. 1), the male terminal of the base unit and the femaleterminal of the removable module are coupled and establish an electrical connection. As can be understood, any other arrangements of male and / or female terminals are possible.

[0100] In some implementations, the base unit 202a may include a load terminal 215 for connecting to an external load (LOAD) wire 214; a line terminal 225 for connecting to a line (LINE) wire 216; a neutral terminal 231 for connecting to a neutral (NEUT) wire 218; and / or a ground terminal 237 for connecting to a ground (GND) wire 220. Moreover, the base unit 202a may include a load terminal 217 for connecting to a load terminal 219 of the removable module 204a; a line terminal 227 for connecting to a line terminal 229 of the removable module 204a; a neutral terminal 233 for connecting to a neutral terminal 235 of the removable module 204a; and / or a ground terminal 239 for connecting to a ground terminal 241 of the removable module 204a. As can be understood, the base unit 202a and / or removable module 204a may include any number of any of the above terminals for providing an electrical connection between the base unit 202a and the removable module 204a and / or any external circuits (e.g., an electrical main). Alternatively, or in addition, one or more of the above terminals in the base unit 202a and / or removable module 204a may be made optional and / or not being used for providing electrical connection between the base unit 202a and the removable module 204a.

[0101] The base unit 202a may further include a switch 208 having one terminal electrically coupled to the wire 216 via connection 222 and another terminal coupled to the switch (SW) wire 210 via terminal 221 of the base unit 202a. The switch 208 may include an open state and a closed state. In the closed state the switch 208 may provide an electrical connection between the LOAD wire 214 and the LINE wire 216 via the SW connection 210. In the open state, the switch 208 disconnects the LINE wire 216 and the LOAD wire 214. The switch 208 may be any type of switch, e.g., mechanical, electrical, electronic, electro-mechanical, and / or any other type.

[0102] The removable module 204a may include type 1 electronic components 206 (e g., switches, electrical receptacles, etc.). The electronic components 206 may be electrically connected to the LINE terminal 229, the NEUT terminal 235, and / or the GND terminal 241. Upon coupling of the removable module 204a and the base unit 202a (e.g., insertion of the removable module 204a into a cavity of the base unit 202a (as, for example, discussed above with regard to FIG. 1)), the electronic components 206 may be connected to the LINE wire 216 via connection of terminal 229 of the removable module 204a and terminal 237 of the base unit 202a. It may also be connected to the NEUT wire 218 via connection of terminals 235 and 233, and to the GND wire 220 via connection of terminals 241 and 239.

[0103] In some implementations, the removable module 204a may include a shunt 211. Upon coupling of the removable module 204a to the base unit 202a, the shunt 211 may provide a low resistance electrical path from the LOAD wire 214 to the SW connection 210. The shunt 211 may be connected to the LOAD terminal 219 and the SW terminal 233 of the removable module 204a.

[0104] Also, once the removable module 204a is coupled to the base unit 202a (including connections between respective pairs of terminals 217 and 219; 221 and 223; 227 and 229, 233 and 235; and 239 and 241), the LOAD wire 214 is connected to the SW connection 210 via the shunt 211. To connect the electronic components 206 to the LOAD wire 214, the switch 208 may be closed, thereby creating an electrical connection from the LOAD wire 214, via the shunt 211, to the LINE wire 216 and to the electronic components 206 via terminals 227, 229. Closing of the switch 208 may be performed in any desired way.

[0105] The system 250a is beneficial in that it provides a simplified wiring structure as well as a smaller number of terminals in the base unit and the removable module, ascompared to some existing systems that include multiple switching components, greater number of terminals as well as connections that must be created within the base units and / or the removable modules to provide appropriate electrical connections between the base units and the removable modules. Because of such simplified wiring structure, the current subject matter is capable of reducing cost and structural complexity of the base units and / or the removable modules, while maintaining their respective intended functionalities.

[0106] As stated above, FIG. 2b illustrates the electrical wiring system 250b having a connector. In particular, the system 250b may include a base unit 202b and a removable module 204b. Other than the inclusion of the connector 212, the base unit 202b may be similar to the base unit 202a. Further, the removable module 204b may be similar to the removable module 204a, except for the absence of the shunt 211. Further, the base unit 202b and the removable module 204b of the system 250b may include terminals (e.g., associated with LOAD, LINE, NEUT, GND) that are similar to corresponding terminals in the system 250a shown in FIG. 2a. As such, for ease of illustration and discussion, reference numerals identifying LOAD, LINE, NEUT, and GND terminals (as shown in FIG. 2a) have been omitted from FIG. 2b.

[0107] As shown in FIG. 2b, the base unit 202b may include the switch 208 and the connector 212 that may be coupled to the LOAD wire 214 and the SW connection 210. The switch connection 210 is not connectable to any of the terminals in the removable module 204b, which is different from the system 250a shown in FIG. 2a. The connector 212 may be used to provide electrical connection between the LOAD wire 214, the LINE wire 216, and the electronic components 206 upon closing of the switch 208. When the switch 208 is open, no electrical connection is provided to the electronic components 206. The connector 212 may be any type ofconnector (e.g., a plastic connector), which may be broken when electrical connection between theLOAD and LINE is no longer required and / or desired.

[0108] As discussed above, the electronic components 206 that may include for example, but are not limited to, a blank removable module, a receptacle removable module, a USB removable module, a guidelight removable module, and / or any other removable modules. These are illustrated in FIGS. 8a-d.

[0109] As shown in FIG. 8a, a base unit 802a having a receptacle 803a may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 804a having a blank cover 805a (e.g., a blank removable module). As shown in FIG. 8b, the base unit 802a having receptacle 803a may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 804b having a receptacle 805b. FIG. 8c illustrates the base unit 802a having receptacle 803a. The base unit 802a may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 804c having a USB 805c. Further, FIG. 8d illustrates the base unit 802a that may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 804d having a guidelight electronic component 805d. The electrical connections may be similar to those discussed above with regard to FIG. 2a-b.

[0110] FIGS. 3a-b illustrate further examples of systems for wiring one or more wiring devices and one or more base units, according to some implementations of the current subject matter. FIG. 3a illustrates an example electrical wiring system 350a that does not include a connector, and FIG. 3b illustrates an example electrical wiring system 350b having a connector.The systems 350a and 350b may be configured to include single-pole base units and removable modules having type 2 electronic components.

[0111] As shown in FIG. 3a, the system 350a may include the base unit 202a and a removable module 304a. The base unit’s 202a LOAD terminal 217 may be connectable to a LOAD terminal 319 of the removable module 304a and its SW terminal 221 may be connectable to a SW terminal 323 of the removable module 304a via a connection 310. As shown in FIG. 3a, the removable module 304a does not include a ground terminal and thus, no connection to the ground terminal 239 may be made. Alternatively, or in addition, the removable module 304a may include a ground terminal for connecting to the ground terminal 339 of the base unit 202a. Further, the base unit 202a and / or removable module 304a may include any number of any of the above terminals for providing an electrical connection between the base unit 202a and the removable module 304a. Alternatively, or in addition, one or more of the above terminals in the base unit 202a and / or removable module 304a may be optional and / or not being used for providing connections between the base unit 202a and the removable module 304a.

[0112] The removable module 304a may include type 2 electronic components 306 that may be electrically connected to LINE and NEUT wires in a similar way as the electronic components 206 shown in FIG. 2a. Moreover, to accommodate for use with type 2 electronic components 306, the electronic components 306 may be electrically connected to a TRIAC 311 positioned within the removable module 304a. Alternatively, or in addition to, a TRIAC, any suitable controllably conductive switch may be used, such as, for example, one or more transistors, thyristors, relays, and / or any other solid state switching device(s) to perform any suitable function, such as, for example, phase control. Examples of transistors include bipolar junction transistors (BJTs), insulated-gate bipolar transistors (IGBT), metal-oxide-semiconductor field-effecttransistors (MOSFETs), and any others. Examples of thyristors may include gate turn-off thyristors (GTOs), silicon-controlled rectifiers (SCRs), triodes for alternating current (TRIACs), and any others. Examples of relays may include electromechanical relays, solid-state relays, and any others.

[0113] Referring back to FIG. 3a, the TRIAC 311 may be a bidirectional, three- electrode alternating current (AC) switch that allows current to flow in either direction. TRIAC may be equivalent of two silicon-controlled rectifiers (SCRs) connected in a reverse-parallel arrangement with gates connected to each other. The TRIAC 311 may be used for a variety of applications, such as, light dimmers, speed controls for fans and / or other electric motors, and / or any other type 2 electronic components 306. The TRIAC 311 may be electrically coupled to the LOAD wire 214 via terminal 319 of the removable module 304a (once the removable module 304a is inserted into the base unit 202a) and to the SW connection 310 via the terminal 323, where, upon closing of the switch 208, current can flow from the LOAD wire 214, via the TRIAC 311, to the LINE wire 216, and the electronic components 306. The TRIAC 311 may also be coupled to the electronic components 306 via an electrical connection 337.

[0114] Upon inserting of and / or otherwise connecting the removable module 304a into / to the base unit 202a, in addition to connecting pairs of terminals 217 and 319; 221and 323; 227 and 329; and 233 and 335 may be formed, the LOAD wire 214 may be connected, via the SW connection 310, to the TRIAC 311a. Upon closing of the switch 208, electronic components 306 may be connected to the LOAD wire 214 via the TRIAC 311.

[0115] FIG. 3b illustrates the electrical wiring system 350b including a base unit202b having a connector 212 and a removable module 304b having a breaker 213. Other thanconnector 212 and the breaker 213, the system 350b is similar to the system 350a shown in FIG.3a.

[0116] The connector 212 may be configured to connect the LOAD 214 and the SW connection 310, where, upon closing of the switch 208, the LINE wire 216 and the LOAD wire 214 may be electrically coupled. However, to ensure that the current from the LOAD wire 214 flows through the TRIAC 311, the breaker 213, positioned in the removable module 304b, may be configured to physically separate the connector 212 to prevent current from the LOAD wire 214 from flowing through the connector 212 and to the LINE wire 214 once the switch 208 is closed.

[0117] As discussed above, the electronic components 306 that may include for example, but are not limited to, a blank removable module, a receptacle removable module, a USB removable module, a guidelight removable module, a dimmer, a smart dimmer, a smart switch, an occupancy sensor and / or any other removable modules. These are illustrated in FIGS. 9a-h.

[0118] As shown in FIG. 9a, a base unit 902a may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 904a having a blank cover 905a (e.g., a blank removable module). As shown in FIG. 9b, the base unit 902a may be arranged and configured to be electrically (and / or mechanically and / or electro- mechanically) coupled to a removable module 904b having a receptacle 905b. FIG. 9c illustrates the base unit 902a. The base unit 902a may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 904c having a USB 905c. FIG. 9d illustrates the base unit 902a that may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 904d having a guidelight electronic component 905d. FIG. 9e illustrates the base unit 902a that may be arrangedand configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 904e having a dimmer electronic component 905e (along with buttons 907). FIG. 9e illustrates the base unit 902a that may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 904e having a smart dimmer electronic component 905e (along with buttons 909). FIG. 9g illustrates the base unit 902a that may be arranged and configured to be electrically (and / or mechanically and / or electro- mechanically) coupled to a removable module 904g having a smart switch electronic component 905g. FIG. 9h illustrates the base unit 902a that may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 904h having an occupancy sensor electronic component 905h. The electrical connections may be similar to those discussed above with regard to FIG. 3a-b.

[0119] FIGS. 4a-b illustrate further example systems 450a without a connector (shown in FIG. 4a) and 450b with a connector (shown in FIG. 4b) for wiring one or more wiring devices and one or more base units, according to some implementations of the current subject matter. The systems 450a and 450b may be configured to include single-pole base units and removable modules having type 3 electronic components.

[0120] The system 450a, as shown in FIG. 4a, may include the base unit 202a and a removable module 404a. Similar to FIG. 3a, the base unit’s 202a LOAD terminal 217 may be connectable to a LOAD terminal 419 of the removable module 404a. The base unit’s SW terminal 221 may be connectable to a SW terminal 423 of the removable module 404a via a connection 410. Similar to FIG. 3 a, connection of the GND terminal 239 ofthe base unit 202a to an appropriate ground terminal (if one is provided) in the removable module 404a may be optional. Again, thebase unit 202a and / or removable module 404a may include any number of any of terminals and / or any number of connections.

[0121] The removable module 404a may include type 3 electronic component 406, a TRIAC 411, and a relay 415, and / or any other component, as discussed above in connection with FIG. 3. The electronic components 406 may be electrically connected to the LINE and NEUT wires via terminals 429, 435, respectively. The TRIAC 411 may be electrically coupled to the LOAD wire 214 via terminal 419 of the removable module 404a (once the removable module 404a is inserted into the base unit 202a). The TRIAC 411 may also be connected to the LINE wire via connection 438 as well as the electronic components 406 via the connection 437. Additionally, the TRIAC 411 may be connected to the relay 415. The relay 415 may be configured to control supply of current to the electronic components 406. The electronic components 406 may be further connected to the SW connection 410 via the terminal 423. Once the switch 208 is closed, the current may flow from the LOAD wire 214, via the TRIAC 411 and / or the relay 415, to the LINE wire 216, and the electronic components 406. This is different from the system 350a (shown in FIG. 3a), where the switch 208 is configured to be connected to the TRIAC rather than directly to the electronic components 306. The electronic components 406 may also include a traveler (TR) connection 439, which may be used when the system 450a is connected to one or more other electrical systems and / or devices (e.g., multiple switches, lights, etc.).

[0122] In operation, the removable module 404a may be inserted into and / or, otherwise, connected to the base unit 202a, which may result in connections between corresponding terminals 217 and 419; 221and 423; 227 and 429; and 233 and 435. This may cause the LOAD wire 214 to be connected to the TRIAC 411 and / or the relay 415 as well as the LINEwire 216. Upon closing of the switch 208, current may be provided, via the SW connection 410, to the electronic components 406.

[0123] FIG. 4b illustrates the electrical wiring system 450b, which may be an alternate implementation of the system 450a, shown in FIG. 4a. The system 450b may include the base unit 202b with a connector 212 and a removable module 404b having a breaker 213. Other than connector 212 and the breaker 213, the system 450b is similar to the system 450a shown in FIG. 4a.

[0124] As discussed with respect to FIG. 3b, the connector 212 may connect the LOAD wire 214 and the SW connection 410. Once the switch 208 is closed, the LINE wire 216 and the LOAD wire 214 may be electrically coupled. The breaker 213, positioned in the removable module 404b, may separate the connector 212 and cause the current to flow to the TRIAC 411. The breaker 213 (as well as breaker 213) may be any type of breaker, e.g., plastic, polymer, etc. and may have any desired shape and / or size that may be configured to provide break in the connector 212 upon inserting and / or coupling of the base unit 202b and the removable module 404b.

[0125] As discussed above, the electronic components 406 that may include for example, but are not limited to, a blank removable module, a receptacle removable module, a USB removable module, a guidelight removable module, a dimmer, a smart dimmer, a smart switch, an occupancy sensor and / or any other removable modules. These are illustrated in FIGS. lOa-h.

[0126] As shown in FIG. 10a, a base unit 1002a may be arranged and configured to be electrically (and / or mechanically and / or electro-mechanically) coupled to a removable module 1004a having a blank cover 1005a (e.g., a blank removable module).

FIG. lOh illustrates the base unit 1002a that may be arranged and configured to be electrically (and / or mechanically and / or electro- mechanically) coupled to a removable module 1004h having an occupancy sensor electronic component 1005h. The electrical connections may be similar to those discussed above with regard to FIG. 4a-b.

[0127] Additional embodiments of multi-way electronic components may be arranged and configured in connection with companion multi-way base units, such as those shown in FIGS. 1 la-e. These may include, but are not limited to, a blank removable module, a receptacle removable module, a USB removable module, a guidelight removable module, an occupancy sensor and / or any other removable modules.

[0128] FIGS. 5a- 7b illustrate alternate wiring systems that may be used in multiway electronic systems (e.g., multiple switches, light fixtures, etc.). In particular, systems shown in FIGS. 5a- 7b may include components and / or wiring structures, such as, for example, removable modules, that are similar to those shown in FIGS. 2a-4b, and that may be used with base units that are suitable for use with multi-way electronic systems.

[0129] FIGS. 5a-b illustrate examples of multi-way electronic (e.g., 3-way electronic) systems for electrically wiring one or more wiring devices and one or more base units, according to some implementations of the current subject matter. FIG. 5a illustrates an example multi-way electronic electrical wiring system 550a having the removable module 204a (shown in FIG. 2a) that includes the shunt 211. FIG. 5b illustrates an example multi-way electronic electrical wiring system 550b having the removable module 204b (shown in FIG. 2b) that includes theconnector 212. The systems 550a and 550b may be configured to include multi-way (as opposed to single-pole) base units and removable modules having type 1 electronic components.

[0130] The system 550a, as shown in FIG. 5a, may include a base unit 502a. Similar to the base unit 202a, the base unit 502a may be connectable to an external electrical circuit (e.g., an electrical main) and / or one or more external wires (not shown in FIG. 2a). The base unit 502a may include LOAD, LINE, NEUT, and GND terminals that are similar to respective terminals of the base unit 202a shown in FIG. 2a and that may be used for external connections and / or for connections to the removable module 204a. As can be understood, any other arrangements of terminals may be possible.

[0131] In addition to the LOAD, LINE, NEUT, and GND terminals, the base unit 502a may also include traveler (TR) terminals 523 and 525 that may be connected on a traveler wire 520. The terminal 523 may be used for connection to an external wire (e.g., to another base unit) and terminal 525 may, optionally, be used for connection to the removable module 204a (if such connection is provided). As can be understood, the base unit 502a may include any number of any of the terminals for providing an electrical connection between the base unit 502a and / or the removable module 204a and / or any external circuits (e.g., an electrical main, other base units, etc.). Alternatively, or in addition, one or more of the above terminals in the base unit 502a and / or removable module 204a may be made optional and / or not being used for providing electrical connection between the base unit 502a and the removable module 204a.

[0132] The base unit 502a may also include a relay switch 508 having one terminal electrically coupled to the wire 216 via connection 222 and another terminal coupled to the switch (SW) wire 510 via terminal 521 of the base unit 502a. The switch 508 may include an open state and a closed state. In the closed state the switch 508 may electrically connect the LOAD wire 214and the LINE wire 216 using the SW connection 510. In the open state of the switch 508, no electrical connection between the LINE wire 216 and the LOAD wire 214 exists. The switch 508 may be any type of switch, e.g., mechanical, electrical, electronic, electro-mechanical, and / or any other type.

[0133] The base unit 502a may also include a multi-way electronic component 522 that may be connected to a button 524. The electronic component 522 may also be connected to the LINE and NEUT wires 216, 218 and may, for instance, be used for coordinating connections, via the TR wire 520, between various multi-way electronic components in other base units. For example, the multi-way electronic component 522 may be used in multiple light switches connected on the same circuit. As can be understood, any type of multi-way electronic components may be used for any desired purposes. In addition to being connected to the multi-way electronic component 522, the button 524 may also be connected to the TR wire 520 as well as the NEUT wire 218. The button 524, which may have an on and an off state, may be used for toggling connections between various base units and / or electronic components 206 in the removable module 204a. The button 524 may be any type of button, e g., mechanical, electrical, electromechanical, etc.

[0134] As discussed above in connection with FIG. 2a, the shunt 211 in the removable module 204a may be used to provide a low resistance electrical path from the LOAD wire 214 to the SW connection 210. The shunt 211 may be connected to the LOAD terminal 219 and the SW terminal 233 of the removable module 204a.

[0135] The system 550b, shown in FIG. 5b, may include a base unit 502b and the removable module 204b. The wiring structure of the system 550b may be similar to the wiring structure of the base unit 502a with the exception of the connector 212. The switch 508 and theconnector 212 may be coupled to the LOAD wire 214 and the SW connection 510. As shown in FIG. 5b, the SW connection 510 might not be connectable to any of the terminals in the removable module 204b, and instead, the connector 212 may provide such electrical connection between the LOAD wire 214, the LINE wire 216, and the electronic components 206 upon closing of the switch 508. Operation of the system 550b may be similar to the operation of the system 250b shown in FIG. 2b.

[0136] FIG. 6a illustrates an electrical wiring system 650a that includes removable module 304a (as shown in FIG. 3a), and FIG. 6b illustrates an example electrical wiring system 650b that includes removable module 304b (as shown in FIG. 3b). Similar to systems 550a, 550b, systems 650a, 650b may include multi-way switch base units. The removable modules in systems 650a, 650b may include type 2 electronic components.

[0137] The system 650a may include the base unit 502a (as shown in FIG. 5a). As discussed above in connection with FIG. 3a, upon connection of the base unit 502a and the removable module 304a, the LOAD terminal 217 of the base unit 502a may be connected to the LOAD terminal 319 of the removable module 304a and the SW terminal 221 of the base unit 502a may be connected to the SW terminal 323 of the removable module 304a using a SW connection 610. As shown in FIG. 6a, the ground terminal may be optional in and / or omitted from the removable module 304a and hence, no connection to the ground terminal 239 may be made. As can be understood, the base unit 502a and / or removable module 304a may include any number of any of the above terminals for providing an electrical connection between the base unit 502a and the removable module 304a.

[0138] The operation of the system 650a may be similar to the operation of the system 650a, but for the base unit 502a being able to operate in a multi-way electronicenvironment. Thus, upon inserting of and / or otherwise connecting the removable module 304a into / to the base unit 502a, the terminals 217 and 319; 221 and 323; 227 and 329; and 233 and 335 may be connected, thereby connecting the LOAD wire 214, via the SW connection 610, to the TRIAC 311. Once the switch 508 is closed, electronic 306 may be connected to the LOAD wire 214 via the TRIAC 311. Any switching between different base units may be accomplished through use of multi-way electronic component 522 and the button 524 via the TR connection 520.

[0139] FIG. 6b illustrates the electrical wiring system 650b including the base unit 502b having the connector 212 and the removable module 604b having the breaker 213. As discussed above in connection with FIG. 3b, the breaker 213 may be used to break the connector 212 and create a connection via the TRIAC 311.

[0140] FIG. 7a illustrates an example system 750a having the removable module 404a (as shown in FIG. 4a), and FIG. 7b illustrates an example system 750b having the removable module 404b (as shown in FIG. 4b), according to some implementations of the current subject matter. Similar to systems shown in FIGS. 5a-6b, the systems 750a, 750b may include multi-way electronic components for connecting multiple base units and / or removable modules, where removable modules include type 3 electronic components.

[0141] The system 750a may include the base unit 502a (as shown in FIG. 5a), where upon connection of the removable module 404a with the base unit 502a, connection between pairs of respective LOAD, LINE, NEUT, (and / or optionally GND) terminals may be made. In addition to these connections, the base unit 502a and the removable module 404a may also be connected using pairs of SW terminals 221 (in the base unit) and 423 (in the removable module), as well as TR terminals 525 (in the base unit) and 725 (in the removable module). In particular, connection between SW terminals 221 and 423 may be configured to form SW connection 710that may link the electronic components 406 and the relay switch 508. Connection between the TR terminals 525 and 725 may link the button 524 (and, hence, the multi-way electronic component 522) and the electronic components 406. As can be understood, the base unit 502a and / or removable module 404a may include any number of any of terminals and / or any number of connections. In operation, once the removable module 404a is inserted into and / or, otherwise, connected to the base unit 502a, and connections between appropriate terminals are formed, the LOAD wire 214 may be connected to the TRIAC 411 and / or the relay 415 as well as the LINE wire 216. Upon closing of the switch 208, current may be provided, via the SW connection 710, to the electronic components 406. Switching between different base units may be accomplished through use of the multi-way electronic component 522 and the button 524 in the base unit 502a.

[0142] FIG. 7b illustrates the electrical wiring system 750b, which may include the base unit 502b with the connector 212 and the removable module 404b having the breaker 213. As discussion in connection with FIG. 4b, the breaker 213 may be used to break the connection formed by the connector 212 in order to establish a connection between the LOAD wire 214 and the TRIAC 411. The remaining operating procedures for the system 750b are similar to the systems discussed above with regard to FIGS. 4b and 5a-7a.

[0143] In some implementations, the current subject matter (e.g., systems shown and discussed in connection with FIGS. 5a- 7b) may be configured to perform multi-way on-off control between primary and / or secondary base units. For example, one or more primary base units and one or more secondary base units may be connected over one or more traveler (TR) wires. The base units may also be connected to one or more device inputs (e.g., removable modules). Further, each of the base units may include a switch that may be configured to control whether electrical signal is supplied to one or more device inputs. When the switch is open, no signal is supplied tothe device inputs. However, when the switch is closed, an electrical signal (e.g., 60 Hz alternating current (AC)) signal may be provided to the device inputs. As such, the electrical signal may be used to as a toggle signal allowing each of the device inputs that are connected over a traveler wire to the primary and / or secondary base units to toggle their load.

[0144] Some electrical systems may use a microcontroller and a switch for user input, where the switch is directly connected to a microcontroller input. The switch is typically connected between two voltage levels that the microcontroller can monitor, e.g., 0V and 3.3V. When the switch is not pressed (e.g., open), the microcontroller detects 3.3V. When the switch is pressed (e.g., closed), the microcontroller detects 0V (and / or vice-versa). The change in the voltage in the microcontroller (e.g., one of its pins) corresponds to a state change of the switch. After detecting this state change, the microcontroller can execute a specific function, which can depend on the logic that it was programmed with it. If the microcontroller is designed to remotely communicate with a separate device when the switch is pressed, the microprocessor may detect the switch’s state change, and then generates its own remote signal that is transmitted to a separate device.

[0145] In some implementations, to ensure compliance with Underwriters Laboratories (UL) standards, an air gap may be provided. In this case, the terminals of the base unit and removable modules may be so designed that upon disconnection of the removable module from the base unit, an air gap may be created. This may be accomplished when male contacts (e.g., blades) of the removable module are removed from the female contacts (e.g., receptacles) of the base unit. The male and female contacts may correspond to the LOAD, LINE, NEUT, and / or GND. One or more of such male contacts may have different lengths than other male contacts (e.g., LOAD male contact of the removable module may be shorter than other contacts). This may allowfor staggered disconnection of male and female contacts of the removable module and the base unit, respectively, where, for example, the LOAD connection between contacts is formed last and disconnected first. Such disconnection fulfills the requirement of the air gap under the UL standards.

[0146] FIGS. 12a-b illustrate an example electrical multi-way wiring system 1200, according to some implementations of the current subject matter. The system 1200 may include a primary base unit 1202, a secondary base unit 1204 and one or more electrical devices 1, 2, 3 1206,1208, 1210 that may be electrically connected to the primary base unit 1202 and secondary base unit 1204 using a traveler wire 1205. The primary and second base units 1202, 1204 may also be connected using the traveler wire 1205.

[0147] The devices 1206, 1208, 1210 may be similar to removable modules shown in FIGS. 2a- 7b and / or 8a-l le. Each of the devices 1206, 1208, and 1210 may include their respective inputs; for instance, the device 1206 may include a device 1 input 1213 (coupled via a resistor 1214 (e.g., 75kOhm)), device 1208 may include a device 2 input 1215 (coupled via a resistor 1216 (e.g., 75kOhm)), and device 1210 may include a device 3 input 1217 (coupled via a resistor 1218 (e.g., 75kOhm)). The inputs may be used to provide electrical inputs to various external devices (e.g., type 1, type 2, type 3, etc. electronic components as shown in FIGS. 2a- 7b and 8a- l ie).

[0148] The primary base unit 1202 may include a neutral wire 1207, a line wire1209, and aground wire 1211, as well as an electrical current source 1201 (e.g., 60 Hz AC source). The electrical current source 1201 may be connected between the neutral wire 1207 and the line wire 1209. The neutral wire 1207 and the line wire 1209 may also be connected to the traveler wire 1205 via respective resistors 1220 (e.g., 5.1k Ohm) and 1222 (e.g., IkOhm), and a switch1203. One or more resistors and / or other electrical components may also be connected to the switch (not shown in FIGS. 12a-b). The switch 1203 may have an open state and a closed state. When the switch 1203 is in the open state, no electrical signal from the source 1201 is supplied on the traveler wire 1205. However, when the switch 703 is closed, an electrical signal (e.g., 60Hz AC signal) may be supplied on the traveler wire 1205. Thus, any device (e.g., device 1206-1210) connected on the traveler wire 1205 will receive this electrical signal. In some example, non-limiting implementations, each device 1206-810 may include internal circuitry (e.g., resistors, other electrical components), to convert this electrical signal into a low voltage input signal. The low voltage input signal may be monitored by each device’s microcontroller. Detection of this signal may mean that the switch 1203 is in the closed state and every device 1206-1208 that is configured to read this signal may then toggle its load.

[0149] Similar process may be performed in the secondary base unit 1204 (as shown in FIG. 12b) that may be connected to one or more devices 1206-1210 using the traveler wire 1205. The secondary base unit 1204 may include its own switch 1221 that may be used to toggle supply of the above electrical signal from the primary base unit 1202 (which is connected to the secondary base unit 1204 using the traveler wire 1205) to the devices 1206-1210. The devices connected to the secondary base unit 1204 may be the same and / or differed devices than those connected to the primary base unit.

[0150] One of the advantages of the system 1200, as compared to existing systems, is that the actuation of the switch 1203 (and / or 1221) causes direct transmission of a remote communication signal that all devices connected on the traveler wire 1205 can detect. Use a switch as an input to a microcontroller means that the microcontroller has to detect the state change of the switch 1205 and then generate its own remote signal on the traveler wire 1205. Using amicrocontroller to transmit the same electrical signal (e.g., 60 Hz AC signal) on the traveler wire 1205 is more expensive and complicated due to the addition of many more electronic components and programmed logic.

[0151] In some implementations, instead of a separate breakers and / or projections and / or breaking members that may be arranged and configured to break, interrupt, disconnect, etc. connectors (whether temporarily and / or permanently) in the base unit, one of the terminals, e.g., a switch (SW) terminal in the removable module(s) may be arranged and configured to break, interrupt, disconnect, etc. such connectors and connect / disconnect LOAD and LINE in the base unit upon insertion / removal of the removable module. FIGS. 13a-d illustrate an example electrical system 1300 having a base unit 1302 and a removable module 1304 while the removable module 1304 is disengaged from the base unit 1302, according to some implementations of the current subject matter. FIGS. 14a-c illustrate the system 1300 while the removable module 1304 is engaged with the base unit 1302. FIGS. 15a-b illustrate electrical diagrams for the system 1300 when it is in disengaged state (FIG. 15a) and in the engaged state (FIG. 15b). While FIGS. 15a-b illustrate schematics for a dimmer insert for the removable module 1304, however, as can be understood, the current subject matter is applicable to any types of insert, either as discussed herein and / or contemplated in the future.

[0152] FIG. 13a illustrates a perspective view of the system 1300 (while the system 1300 is removed from a wall or any other installation location). As stated above, the system 1300 may include the base unit 1302 and the removable module 1304 that may be arranged and configured to be inserted into a cavity within the base unit 1302 (as discussed herein). As shown in FIG. 13a, the removable module 1304 is partially inserted into the cavity and thus, is electrically disengaged from the base unit 1302. The base unit 1302 may include various contacts and / orterminals (e.g., a connection 1306 for a LINE terminal and a connection 1308 for a LOAD terminal are shown in FIG. 13a, whereas other connections are not shown in FIG. 13a) that may be arranged and configured for electrical coupling to respective contacts and / or terminals of the removable module 1304. FIG. 13b illustrates another perspective view of the system 1300 with the back cover over the base unit 1302 being removed and showing the removable module 1304 being partially inserted into the base unit 1302.

[0153] FIG. 13c illustrates a perspective side view of the system 1300, where back covers of the base unit 1302 and the removable module 1304 have been removed. As shown in FIG. 13c, the base unit 1302 may include a line terminal 1301, a load terminal 1303, a ground terminal 1305, a traveler connection / terminal 1307, and a neutral terminal 1309. Moreover, the base unit 1302 may also include a switch 1319 that may be used to connect / disconnect connection between the load and line terminals 1301 and 1303.

[0154] The removable module 1304 may include a line terminal 1311, a switch terminal 1313, a load terminal 1315, a traveler connection / terminal 1317, and a neutral terminal 1321 along with various electrical / electronic elements / circuitry 1320. The switch terminal 1313 may be configured to replace the breaker shown and discussed above in connection with FIGS. 2a-7b and / or FIGS. 8a- 1 le, and may arranged and configured to serve as a breaker and a connector between terminals in the base unit 1302 and the removable module 1304. Upon insertion and electrical connection of the removable module 1304 and the base unit 1302, the line terminal 1311 is arranged and configured to connect with the line terminal 1301 of the base unit 1302; the load terminal 1315 is arranged and configured to connect with the load terminal 1303; the traveler connection / terminal 1317 with the traveler connection / terminal 1307, and the neutral terminal1321 with the neutral terminal 1309. When the removable module 1304 is not electrically coupledto the base unit 1302, the switch 1319 is closed (as shown in FIG. 15a), thereby providing an electrical connection between the line terminal 1301 and the load terminal 1303 in the base unit1302. FIG. 13d illustrates a further perspective side view of the system 1300 (with various structural features removed), which provide an enhanced view of the terminals of the removable module 1304.

[0155] FIG. 14a illustrates a perspective view of the system 1300 (while the system 1300 is removed from a wall or any other installation location). As shown in FIG. 13a, the removable module 1304 is fully inserted into the cavity of the base unit 1302 and is electrically engaged with the base unit 1302. The base unit 1302’s contacts and / or terminals may be arranged and configured to electrically couple to respective contacts and / or terminals of the removable module 1304. FIG. 14b illustrates another perspective view of the system 1300 with the back cover over the base unit 1302 being removed and showing the removable module 1304 being fully inserted into the base unit 1302 and having respective terminal s / contacts of the base unit 1302 and removable module 1304 being electrically connected (while the switch terminal being disengaged.

[0156] As shown in FIGS. 14b-c (FIG. 14c illustrating a portion of the FIG. 14b), the switch terminal 1313 serves as a breaker and a connector between terminals in the base unit 1302 and the removable module 1304. Upon insertion and electrical connection of the removable module 1304 and the base unit 1302, the line terminal 1311 connects with the line terminal 1301 of the base unit 1302; the load terminal 1315 connects with the load terminal 1303; the traveler connection / terminal 1317 connects with the traveler connection / terminal 1307, and the neutral terminal 1321 connects with the neutral terminal 1309. Once the removable module 1304 is electrically coupled to the base unit 1302, the switch 1319 is open (as shown in FIG. 15b), therebyproviding an electrical connection for the removable module 1304, and in particular, connecting the switch terminal of the removable module and the line terminal of the base unit 1302.

[0157] In some embodiments, it may be important for a removable module to know which base unit it has been inserted and / or connected to / with. Alternatively, or in addition, it may be important for a base unit to know which removable module has been inserted into it and / or connected with. For example, such knowledge may be helpful for the purposes of establishing various switching connections between base units and / or removable modules, e.g., where one base unit may be a primary base unit (e.g., that may receive one removable module) and another base unit may be a secondary base unit (e.g., that may receive another removable module). Some electrical systems may use a microcontroller and a switch, where the switch is directly connected to a microcontroller input. The switch is typically connected between two voltage levels that the microcontroller can monitor, e.g., 0V and 3.3V. When the switch is not pressed (e.g., open), the microcontroller detects 3.3V. When the switch is actuated (e.g., closed), the microcontroller detects 0V (and / or vice-versa). The change in the voltage in the microcontroller (e.g., one of its pins) corresponds to a state change of the switch and hence, the microcontroller. After detecting this state change, the microcontroller can execute a specific function, which can depend on the logic that it was programmed with it. In some implementations, changing of the state (e.g., 3.3 V) may cause the microcontroller to determine that its input device (e.g., removable module) has been inserted into a specific base unit, which may cause the microcontroller to assume one or more settings associated with that base unit. Conversely, if, upon insertion of the input device (e.g., removable module) into another base unit, may cause the microcontroller to remain in its original or neutral state (e.g., 0 V) and determine that its input device has been inserted into such other base unit and assume one or more setting associated therewith.

[0158] In some implementations, the current subject matter may relate to an electrical system. The electrical system may include one or more base units that may electrically connect to a source of electrical current. The system may also include one or more removable modules that may be configured for electrically coupling to the base unit(s). The removable module(s) may include a microcontroller. The microcontroller may have a first operating state and a second operating state. The operating states of the microcontroller may be dependent on a particular base unit that the removable module(s) has been inserted into and / or coupled with. The first operating state may be associated with a first digital identifier that may identify the primary base unit. Thus, coupling of the removable module(s) to the primary base unit causes the removable module’s microcontroller to use the first digital identifier to determine that the removable module has been inserted into or coupled with to the primary base unit.

[0159] The base units may include base unit terminals and the removable module may include one or more removable module terminals, which, upon coupling of the removable module and the base units, the base unit terminals may electrically couple to the removable module terminals. Further, the base units may include at least one of the following: one or more receptacle base units, one or more single-pole base units, one or more multi-way base units, one or more companion multi-way base units, and any combination thereof. The one or more multi-way base units may include a traveler connection for electrically connecting the one or more multi-way base units to at least one of one or more receptacle base units, one or more single-pole base units, one or more multi-way base units, one or more companion multi-way base units, and any combination thereof.

[0160] Moreover, the removable module(s) may include a selectively activatable actuator, which may enable a change in operating state of the microcontroller and hence,determination that the removable module has been inserted into a particular base unit. For example, upon coupling of the removable module(s) to a primary or a first base unit, the actuator might not be activated. This may cause the removable module’s microcontroller to remain in the first operating state, which may indicate that the removable module has been inserted into or coupled with the primary base unit.

[0161] However, upon coupling of the removable module(s) to a secondary or a second base unit, the actuator may be activated. This may trigger actuation of a second operating state of the microcontroller and a determination by the microcontroller that the removable module has been inserted into or coupled with the secondary base unit. The second operating state may be associated with a second digital identifier identifying the secondary base unit. As with the first operating state, coupling of the removable module to the secondary base unit causes the microcontroller to use the second digital identifier to determine that the removable module has been inserted into or coupled with to the secondary base unit. In some implementations, the secondary base unit may be a companion base unit to the primary base unit and / or vice versa.

[0162] In some implementations, the actuator may be a spring-loaded mechanical actuator. For example, the actuator may be a rod that may extend through at least a portion of the housing of the removable module with its one end being coupled to a tensioned spring and having another end partially protruding through an opening in the housing of the removable module. The spring may be coupled to a circuit board of the microcontroller and may provide an ability to trigger switching between first and second states of the microcontroller. The actuator may include an actuated state and a neutral state. In the actuated state, the actuator translates inside the housing of the removable module in a first direction causing the spring to disengage thereby triggering an electrical connection in the microcontroller and causing the microcontroller to be placed into thesecond operating state (hence, determining that the removable module has been inserted into the secondary base). In the neutral state, the spring is engaged, thereby interrupting an electrical connection in the microcontroller and causing the microcontroller to be placed in the first operating state (hence, determining that the removable module is outside of the secondary base unit and / or inside the primary base unit). Moreover, the actuator’s one end (i.e., end that is opposite of the end that includes the spring) protrudes outside of the opening of the housing in the neutral state.

[0163] In some implementations, to trigger movement of the actuator, one of the base units, e.g., secondary base unit may include an activation block. Upon coupling of the removable module and the secondary base unit, the activation block may engage the actuator causing the actuator to translate inside the interior housing of the removable module in a first direction, thereby triggering the electrical connection in the microcontroller. However, upon removing of the removable modules from the secondary base unit and / or positioning of the removable module in the primary base unit, the activation block may disengage from (or not engage as the primary base unit does not include such block) the actuator causing the actuator to translate in the interior housing of the removable module in the second direction (or assume the neutral state) causing the microcontroller to return to or remain in the first operating state.

[0164] Alternatively, or in addition, the actuator may include at least one of the following: an optoelectronic element (e.g., optocoupler, opto-isolator, photodiode, photodetector, photosensor, photo-transistor, photo-interrupter), an electrical actuator, or any combination thereof. In this case, the secondary base unit may include a device (e.g., a wall, a screen, an optical grating, a dielectric / insulator member, etc.) that may interrupt the actuator. In particular, upon coupling of the removable module and the secondary base unit, the interrupt device may interrupt the actuator triggering the electrical connection in the microcontroller and causing themicrocontroller to be placed into the second operating state. Similarly, upon removing of the removable module from the secondary base unit or positioning it into the primary base unit, the interrupt device may disengage from (or not engage with) the actuator breaking the electrical connection in the microcontroller causing the microcontroller to return to (or remain in) the first operating state.

[0165] FIGS. 16a-f are various views of an example removable module 1600, according to some implementations of the current subject matter. The removable module 1600 may be insertable into a base unit (not shown in FIGS. 16a-f), which may be similar to arrangement of the removable module 104a and base unit 102 shown in FIG. 1.

[0166] The removable module 1600 include a housing 1602 that may be configured to house electronic components that may be used to provide various functionalities (e.g., an outlet, a light switch, a dimmer switch, a USB port, etc.) to the removable module 1600 once it is inserted into the base unit. The removable module’s housing 1602 may include a front portion 1604, a back portion 1606, side portions 1608 (a, b), atop 1607, and bottom 1609. The removable module 1600 may be configured to be inserted into the base unit with the rear portion 1606 facing the base unit’s interior cavity (e.g., interior cavity 114 as shown in FIG. 1). The removable module 1600 may further include one or more removable module terminals 1610 that may be configured to connect with corresponding base unit terminals (e.g., terminals 116) upon insertion of the removable module 1600 into the base unit, thereby forming an electrical connection between the removable module and the base unit. This electrical connection may provide electrical power to the electronic components housed in the housing 1602 of the removable module 1600.

[0167] The removable module 1600 may also include a selectively activatable actuator 1612. The actuator 1612 may include a distal end 1613, a proximal end 1615, and anactuator body 1617 disposed between the distal end 1613 and the proximal end 1615. The distal end 1613 of the actuator 1612 may be configured to protrude through an opening 1614 in the back portion 1606 of the housing 1602 of the removable module 1600. The distal end 1614 may have a shape of a platform and may be wider (in at least one dimension) that than actuator body 1617.

[0168] The actuator body 1617 may be configured to protrude through at least a portion of an interior space 1601 of the removable module housing 1602. For example, as shown in FIGS. 16c-f, the actuator body 1617 may protrude from the opening 1614 to an opening in a circuit board 1618. The circuit board 1618 may include microcontroller electronic components 1603 (hereinafter, “microcontroller” 1603) and / or any other processing components of the removable module 1600. The microcontroller 1603 may control various operational functions of the removable module 1600, which may depend on a specific purpose that the removable module 1600 is being used for (e.g., an outlet, a switch, a dimmer switch, a USB port, etc.).

[0169] In some implementations, the actuator body 1617 may be configured to be rigid, semi-rigid and / or semi-flexible. The actuator body 1617 may also have one or more portions that may have different degrees of rigidity / flexibility . The actuator body 1617 may be manufactured from any desired material (while complying with all applicable standards, codes, and regulations). For instance, the body 1617 may be manufactured from plastic, composite, polymer, resin and / or any other suitable materials.

[0170] The proximal end 1615 of the actuator 1612 may be coupled to a spring and / or any other tensioning device 1619. The spring 1619 may be mounted on a pin 1629, as shown in FIGS. 16c-f. This may allow the spring 1619 to at least partially rotate about the pin 1629. The spring 1619 may include a first end 1621 and a second end 1625. The first end 1621 of the spring 1619 may be movably mounted or positioned at an opening 1623 on the circuit board 1618. Thesecond end 1625 may be securely mounted or positioned at an opening 1627 of the circuit board 1618. The first end 1621 may be configured as an electrical switching connection for the microcontroller 1603. The second end 1625 along with the pin 1629 may be configured to secure the spring 1619 in place.

[0171] The spring 1619 may also be movably coupled to the distal end 1615, and in particular, be positioned in a groove 1631 at the distal end 1615 of the actuator 1612, as shown in FIG. 16e. Translation of the actuator 1612 within the interior 1601 of the housing 1602 of the removable module 1600 toward its proximal end 1615 (which also causes the distal end 1613 to translate through the opening 1614 and, at least partially, into the interior 1601 of the housing 1602) may apply force to the spring 1619 at the mounting groove 1631. This, in turn, causes the spring 1619 to rotate about the pin 1629 in a proximal direction. Rotation of the spring 1619 about the pin 1629 also causes movement of the first end 1621, which pulls the first end 1621 from the opening 1623 in the circuit board 1618. Pulling of the first end 1621 from the opening 1623 causes the above electrical switching connection for the microcontroller 1603 to change states (e.g., pulling of the first end 1621 either opens or closes of the electrical switching connection), thereby either electrically connecting the microcontroller 1603 to ground (e.g., 0 V) or to voltage (e.g., 3.3 V), as shown in FIGS. 17a-d and 19.

[0172] Conversely, translation of the translation of the actuator 1612 within the interior 1601 of the housing 1602 of the removable module 1600 toward its distal end 1613 (which causes the distal end 1613 to translate away from the interior 1601 of the housing 1602 and out of the opening 1614) may release the spring 1619 at the mounting groove 1631. This results in the spring 1619 rotating about the pin 1629 in a distal direction (opposite of the proximal direction). This rotation causes movement of the first end 1621 back through the opening 1623 in the circuitboard 1618. Return of the first end back through the opening 1623 causes the above electrical switching connection for the microcontroller 1603 to again change states (e.g., return of the first end 1621 through the opening 1623 either closes or opens the connection, which may be opposite to when the first end is pulled out of opening 1623), thereby electrically connecting the microcontroller 1603 to voltage (e.g., 3.3 V) or to ground (e.g., 0 V), as shown in FIGS. 17a-d and 19.

[0173] The actuator 1612 may be positioned anywhere in the removable module 1612. It may also have any desired shape and / or form. It may also be configured to open and / or close the electrical switching connection for changing states of the microcontroller 1603 in any desired way.

[0174] In some implementations, the actuator 1612 may be used in connection by the removable module 1600 in connection with a process of identifying a particular base unit that the removable module 1600 has been inserted or positioned into. To assist with such identification, base units may include one or more mechanisms and / or devices and / or structural features that may be configured to interact with the actuator 1612, and, in particular, for example, with the distal end 1614 of the actuator 1612. Such interaction may cause translation movement of the actuator 1612 within the interior 1601 of the housing 1602 of the removable module 1600.

[0175] FIGS. 17a-d illustrate electrical systems 1700 (as shown in FIGS. 17a-b) and 1720 (as shown in FIGS. 17c-d) for identifying a base unit by a removable module, according to some implementations of the current subject matter. As shown in FIGS. 17a-b, the system 1700 may include a base unit 1702 and the removable module 1600, and, as shown in FIGS. 17c-d, the system 1720 may include a base unit 1712 and the removable module 1600.

[0176] Referring to FIGS. 17a-b, the base unit 1702 may include an interior 1704 that may be configured to receive the removable module 1600 by inserting the removable module 1600 into the interior 1704 as shown by the arrow in FIG. 17a. Once fully inserted, the rear portion 1606 of the removable module 1600 may be positioned substantially adjacent to a back wall 1706 of the base unit 1702. As shown in FIG. 17b, the rear portion 1606 may include one or more protruding pins 1641 (a, b) that may prevent the rear portion 1606 from touching the back wall 1706 of the base unit 1702. The protruding pins 1641 may have a length that is greater than a distance that the distal end of the 1613 protrudes outside of the rear portion 1606 of the removable module 1600. This may prevent the back wall 1706 from touching and applying force on the distal end 1613 of the actuator 1612 during insertion, as shown in FIG. 17b.

[0177] Since no force is applied to the distal end 1613 of the actuator 1612, the actuator 1612 does not translate and, hence, does not cause rotation of the spring 1619, i.e., the spring 1619 remains in its stationary or neutral position. Stationary / neutral position of the spring 1619 does not change the electrical switching connection of the microcontroller 1603, and thus, does not change the operating state of the microcontroller 1603, e.g., either 0 V or 3.3 V, which may depend on a configuration of the removable module 1600. Since the state of the microcontroller 1603 has not been changed, upon forming of an electrical connection between terminals of the base unit and the removable module, the removable module’s microcontroller 1603 may be configured to determine that the removable module 1600 has been inserted into the base unit 1702. For example, the base unit 1702 may be a primary base unit, which may be connected to a secondary or companion base unit (not shown in FIGS. 17a-b) using a traveler wire. Alternatively, the base unit 1702 may be a secondary or companion base unit that may be connected to a primary base unit. Further, upon forming of electrical connection using terminalsof the base unit and the removable module, the microcontroller 1603 may be configured to receive one or more settings associated with the base unit 1702. For instance, the settings may include operational status, other base units that the base unit 1702 may be connected to and that the removable module 1600 may send signals to and / or control, etc. The microcontroller 1603 of the removable module 1600 may be configured to store (e.g., in a storage location) and use these settings while being inserted into the base unit 1702 and / or for use with any other base units that may be similar to the base unit 1702.

[0178] Referring to FIGS. 17c-d, the base unit 1712 may include an interior 1714 that may be configured to receive the removable module 1600 as shown by the arrow in FIG. 17c (similar to the interior 1704 shown in FIG. 17a). Once fully inserted, the rear portion 1606 of the removable module 1600 may be positioned substantially adjacent to a back wall 1716 of the base unit 1712. The back wall 1716 may also include a protrusion or activation block 1718 that may be configured to interact with the distal end 1613 of the actuator 1612. The length of the block 1718 and / or a distance that it extends form the back wall 1716 may be greater than the length of the protruding pins 1641 that protrude from the rear portion 1606. Because of that, the protruding pins 1641 do not interfere with the block 1618 interacting with or applying force to the distal end 1613 of the actuator 1612 during insertion of the removable module 1600 into the interior 1714 of the base unit 1712, as shown in FIG. 17d.

[0179] As the force is applied to the distal end 1613 of the actuator 1612 by the block 1718 as a result of the movement shown by the arrow in FIG. 17c, the actuator 1612 may translate toward the proximal end of the actuator 1612 in the interior of the housing 1602 of the removable module (as shown by the arrow in FIG. 17d). This, in turn, may cause rotation of the spring 1619 and movement of the first end 1621 of the spring 1619 away from the opening 1623,thereby placing the spring 1619 into an actuated position. Actuated position of the spring 1619 may change the electrical switching connection of the microcontroller 1603, and hence, may change the operating state of the microcontroller 1603, e.g., either 3.3 V or 0 V, which may again depend on a configuration of the removable module 1600.

[0180] Since the state of the microcontroller 1603 has been changed, upon forming of an electrical connection between terminals of the base unit and the removable module, the removable module’s microcontroller 1603 may be configured to determine that the removable module 1600 has been inserted into the base unit 1712, which may be connected to the base unit 1702 (as shown in FIGS. 17a-b) using a traveler wire. For example, since, as discussed above, the base unit 1702 may be a primary base unit, the base unit 1712 may be a secondary or companion base unit. Alternatively, the base unit 1702 may be a secondary or companion base unit and the base unit 1712 may be a primary base unit.

[0181] Similarly, upon forming of electrical connection using terminals of the base unit and the removable module, the microcontroller 1603 may be configured to receive one or more settings associated with the base unit 1712, which may include information about which base units the base unit 1712 may be connected and / or any other settings, as discussed herein. The microcontroller 1603 may store (e.g., in a storage location) and use these settings while being inserted into the base unit 1712 and / or for use with any other base units that may be similar to the base unit 1712. Moreover, the microcontroller 1603 may be configured to store settings of different types of base units (e.g., base units 1702, 1712). It may retrieve (e.g., from a storage location) and execute appropriate settings upon removable module 1600 being inserted into and / or connected with a particular base unit. Retri eval / execution of such settings may depend on whether or not base unit’s structural features (e.g., activation block 1718) may have caused the actuator 1612 totranslate, thereby affecting operational states of the microcontroller 1603. As can be understood, other ways of changing operational states of the microcontroller 1603 are possible.

[0182] FIGS. 18a-d illustrate electrical systems 1800 (as shown in FIGS. 18a-b) and 1820 (as shown in FIGS. 18c-d) for identifying a base unit by a removable module, according to some implementations of the current subject matter. As shown in FIGS. 18a-b, the system 1800 may include a base unit 1802 and a removable module 1804, and, as shown in FIGS. 18c-d, the system 1820 may include a base unit 1812 and the removable module 1804. The base units 1802, 1812 and the removable module 1804 may be similar to the base unit(s) and removable module(s), respectively shown and discussed in connection with FIGS 16a-17d.

[0183] Referring to FIGS. 18a-b, the base unit 1802 may include an interior that may be configured to receive the removable module 1804 by inserting the removable module 1804 into the interior as shown by the arrow in FIG. 18a. As shown in FIGS. 18c-d, the base unit 1812 may also include an interior that may receive the removable module 1804.

[0184] The removable module 1804 may be configured to include one or more sensors 1806. The sensors 1806 may be communicatively coupled to a microcontroller 1808 of the removable module 1804. The sensors 1806 may be used to detect which base unit the removable module 1804 has been inserted into. The sensors 1806 may include at least one of the following: light emitting diode (LED) sensors, magnetic sensors, electrical sensors, pressure sensors, infrared sensors, optical sensors, ultrasonic sensors, and / or any other sensors. The removable module 1804 may include one or multiple sensors 1806.

[0185] The base units may include one or more sensor interaction devices that may be used for interaction with the sensor(s) 1806 of the removable module 1804. For example, as shown in FIGS. 18c-d, the base unit 1812 may include a sensor interaction device 1814 that mayinteract with the sensor(s) 1806. The sensor interaction device 1814 may be a reflective plate, a source of light, a magnet, an electrical connection, and / or any other device that the sensor(s) 1806 may interact with and / or detect, and as a result, send a signal to the microcontroller 1808. The signal may be indicative of the base unit (e.g., base unit 1812) that the removable module 1804 has been inserted into. The microcontroller 1808 may process the received signal and change its operational state accordingly.

[0186] Alternatively, or in addition, the base units, e.g., base unit 1802 (as shown in FIGS. 18a-b), might not include a sensor interaction device. Thus, upon insertion of the removable module 1804 into the base unit 1802, the sensor(s) 1806 do not detect a sensor interaction device and thus, do not send any signals to the microcontroller 1808, thereby not affecting its operational state. This may cause the microcontroller 1808 to determine that it has been inserted into the base unit 1802 and retrieve (and / or request and / or receive from base unit 1802) setting(s) associated with the base unit 1802.

[0187] In some implementations, the microcontroller may be preloaded with various settings associated with one or more base units. Upon receiving signal (or not receiving a signal), the microcontroller may retrieve settings corresponding to the base units into which the removable module has been inserted into. The settings may be retrieved from a local storage location. Alternatively, or in addition, the settings may be requested and / or received from the base unit. Further, such retrieval / receipt of settings may be accomplished upon forming of a connection between the base unit and the removable module.

[0188] FIG. 19 illustrates an electrical wiring system 1900 that may be used for changing of operational states (e.g., 3.3 V or 0 V (e.g., ground)) of a microcontroller, according to some implementations of the current subject matter. The changing of the operational states of themicrocontroller may be triggered using any of the systems shown in FIGS. 16a-4d and / or using any other electrical, optical, mechanical, electro-optical, electro-mechanical, and / or any other type of mechanisms / devices.

[0189] As shown in FIG. 19, the system 1900 may include a connection 1902 that may be used to trigger opening and / or closing of a switch SW1 1908. The switch 1908 may be configured to connect the microcontroller of the removable module (not shown in FIG. 19) either to power source 1904 (e.g., 3.3 V via a resistor 1910) or to ground (GND) 1906. For example, if the switch 1908 is open (i.e., no connection between points 1 and 2), the microcontroller may be connected to the power source 1904. If the switch 1908 is closed, the microcontroller may be disconnected from the power source 1904 and, instead, connected to the GND 1906.

[0190] Opening or closing of the switch 1908 may be triggered by receiving (and / or not receiving) a signal on the line 1902. For instance, upon receiving a signal on the line 1902 (e.g., when the removable module is inserted into and electrically coupled to a secondary base unit), the switch 1908 opens (disconnecting points 1 and 2) causing the microcontroller to be connected to the power source 1904. This connection causes the microcontroller to assume (and / or change to) an operational state consistent with the removable module being inserted into the secondary base unit. However, when no signal is received on the line 1902 (e.g., when the removable module is inserted into and electrically coupled to a primary base unit), the switch 1908 remains closed causing the microcontroller to be connected to the GND 1906. This connection causes the microcontroller to assume (and / or change to) an operational state consistent with the removable module being inserted into the primary base unit. As can be understood, any other arrangements of connections and their triggers may be used.

[0191] In some implementations, one or more components of the systems may be manufactured from any desired materials that may be suitable for a particular application (while complying with all applicable standards, codes, and regulations). For example, the base units, removable modules, etc. may be manufactured from plastic, composite, polymer, resin and / or any other suitable materials. Any electrical components, including any contacts and / or terminals, may be manufactured from metal, copper, and / or any other desired materials that may be used for conducting of electricity. The systems shown may be used for any desired purposes, e.g., light switches, electrical outlets, USB connections, Internet connections, etc.
