Description

[0001] Cross-referencing of relevant cases

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 756,637, filed November 7, 2018, and U.S. Provisional Patent Application No. 62 / 878,527, filed July 25, 2019, the contents of which are incorporated herein by reference in their entirety. Background Technology

[0003] During the installation of a typical load control system, standard mechanical switches (such as traditional toggle switches or decorative rocker switches) may be replaced with more advanced load controllers (such as dimmer switches) that control the flow of electricity from alternating current (AC) power to one or more electrical loads. This type of installation typically requires disconnecting the existing mechanical switches from the electrical wiring and removing them from their mounting box, then connecting the load controller to the electrical wiring and installing it in the box. The average consumer may be reluctant to perform the necessary electrical wiring for such an installation. Therefore, this process is usually performed by an electrical contractor or other skilled installer. However, hiring an electrical contractor may be prohibitively expensive for the average consumer.

[0004] Controllable light sources, such as controllable screw-in light-emitting diode (LED) lamps, offer a simpler solution for advanced lighting control. For example, simply unscrew the older incandescent bulb from the socket and screw the controllable light source in. The controllable light source can be controlled by a remote control. However, the socket in which the controllable light source is installed can be controlled by an existing wall-mounted light switch. When the wall-mounted light switch is operated to the off position, power to the controllable light source may be cut off, causing the light source to potentially become unresponsive to commands transmitted by the remote control. Therefore, it is desirable to prevent such operation of the wall-mounted light switch to ensure a continuous and uninterrupted power delivery to the controllable light source. Summary of the Invention

[0005] As described herein, a remote control device used in a load control system (e.g., to control electrical loads and / or load control devices) can be configured to be mounted above an installed mechanical switch with a rocker actuator. The mechanical switch controls whether power is delivered to the electrical load. The remote control device can be installed without touching the electrical wiring of the mechanical switch.

[0006] The remote control may include a base and a control unit configured to be removably attached to the base. The control unit may include a user interface and wireless communication circuitry. The control unit may convert user input received at the user interface into control signals for controlling a load control device. The control unit may enable the wireless communication circuitry to transmit the control signals.

[0007] The base can include a frame, a clip arm, a screw, and / or a sleeve. The frame can define an opening configured to receive a protruding portion of a rocker actuator. The frame can at least partially enclose the rocker actuator when the protruding portion of the rocker actuator is received in the opening. The frame can include an outer wall extending along a perimeter of the frame. The frame can define one or more teeth extending into the opening. The one or more teeth can be configured to engage the protruding portion of the rocker actuator, for example to secure the base to the protruding portion of the rocker actuator. The frame can be configured for releasably attaching a control unit. The outer wall can define one or more snaps configured to engage corresponding features in the control unit.

[0008] The clip arm can define one or more teeth configured to engage the protruding portion of the rocker actuator, for example to secure the base to the protruding portion of the rocker actuator. The clip arm can be configured to secure the base to the protruding portion of the rocker actuator. The sleeve can be defined by the frame or can be attached to the frame. The sleeve can include a threaded hole therethrough. The screw can be received in the sleeve and can be in operative engagement with the clip arm. When the screw is rotated, the clip arm can move toward the protruding portion of the rocker actuator until the clip arm abuts the protruding portion of the rocker actuator. The clip arm can be configured to exert a force on the protruding portion of the rocker actuator as the screw is further rotated when the clip arm abuts the protruding portion of the rocker actuator. The force exerted by the clip arm can be configured to secure the base to the protruding portion of the rocker actuator.

[0009] The clip arm can be attached to the frame at a pivot joint. The clip arm can be configured to pivot about the pivot joint. The pivot joint can be located near a midpoint of the frame. The clip arm can define a threaded hole configured to receive a screw. The screw (e.g., a head of the screw) can be configured to pull the clip arm toward the protruding portion of the rocker actuator when the screw is rotatably received by the threaded hole.

[0010] Alternatively, the pivot joint can be located near a lower edge of the frame. The clip arm can define a plate configured to engage a distal end of the screw. The screw can be configured to push the plate when rotated such that the clip arm moves toward the protruding portion of the rocker actuator when the distal end of the screw engages the plate.

[0011] A remote control device can include a battery holder configured to be received within a void defined by the remote control device. The battery holder can be configured to receive a battery to power electrical circuitry of the remote control device. The battery holder can include a mounting flange, a first arm, and a second arm. The mounting flange can be configured to attach the battery holder to a printed circuit board (PCB) of the remote control device. The first arm can extend from the mounting flange in a first direction. The first arm can be configured to secure a battery of the remote control device within the battery holder in a first position. The second arm can extend from the mounting flange in a second direction opposite the first direction. The second arm can be configured to secure the battery of the remote control device within the battery holder in a second position. The first arm can be configured to electrically couple the battery to the remote control device via the PCB in the first position. The second arm can be configured to electrically couple the battery to the remote control device via the PCB in the second position.

[0012] A battery holder of a remote control device can include a mounting flange, electrical contact members, a slot, and a tab. The mounting flange can be configured to attach the battery holder to a PCB of the remote control device. The electrical contact members can extend between the mounting flange. The electrical contact members can be configured to electrically couple a battery to the remote control device via the PCB. The electrical contact members can define a first edge and an opposite second edge. The electrical contact members can be configured to secure the battery of the remote control device within the battery holder in a first position when mounted from the first edge. The electrical contact members can be configured to secure the battery of the remote control device within the battery holder in a second position when mounted from the second edge. The slot can be defined between the electrical contact members and the PCB. The slot can be configured to receive the battery. The tab can be configured to engage the battery when mounted in the first position and the second position. The tab can be configured to prevent the battery from being mounted within the battery holder beyond a predefined position.

[0013] A remote control device can include a control unit, a cover base, a cover portion, and a control base. The control unit can include a user interface and / or a wireless communication circuit. The control unit can be configured to convert user input from the user interface into control signals that control a load control device. The control unit can be configured to cause the wireless communication circuit to transmit the control signals. The cover base can define an opening configured to receive a protruding portion of a paddle actuator of a mechanical switch. The protruding portion of the paddle actuator can protrude outward when the mechanical switch is operated to a position that causes power to be delivered to an electrical load. The frame can at least partially enclose the paddle actuator when the protruding portion is received in the opening. The cover base can include a clamp arm configured to secure the cover base to the protruding portion of the paddle actuator. The cover base can include a screw that operatively engages the clamp arm such that when the screw is rotated, the clamp arm moves toward the protruding portion of the paddle actuator until the clamp arm abuts the protruding portion of the paddle actuator. The cover portion can be configured to cover the paddle actuator and the cover base. The control unit can be configured to be releasably attached to the control base. The clamp arm can be configured to exert a force on the protruding portion of the paddle actuator as the screw is further rotated when the clamp arm abuts the protruding portion of the paddle actuator. The force exerted by the clamp arm can be configured to secure the cover base to the protruding portion of the paddle actuator. BRIEF DESCRIPTION OF DRAWINGS

[0046] Figure 1 An example remote control device 100 that can be installed in a load control system, such as a lighting control system, is depicted. Figures 2-8 An example base 120 (e.g., base component) of the example remote control device 100 installed in a load control system is depicted. The load control system can include a mechanical switch, such as the mechanical switch 190 shown, which can be in place prior to installation of the remote control device 100, e.g., pre-existing in the load control system. As shown, the mechanical switch 190 can be a standard decorator toggle switch. The load control system can also include one or more electrical loads, such as lighting loads. The mechanical switch 190 can be coupled in series electrical connection between an alternating current (AC) power source and the one or more electrical loads (not shown).

[0047] The mechanical switch 190 can include a toggle actuator 192 that is actuatable to turn on and / or turn off the one or more electrical loads. The mechanical switch 190 can include a bezel 194 that surrounds the toggle actuator 192. The mechanical switch 190 can include a yoke (not shown) that enables the mechanical switch 190 to be mounted to a structure. For example, the yoke of the mechanical switch 190 shown can be fastened to a single gang wall box that is mounted in an opening in a wall. As shown, a faceplate 196 can be secured to the mechanical switch 190, e.g., to the yoke. The faceplate 196 can define an opening 198 that extends therethrough. The opening 198 can be sized to receive the bezel 194 therein such that a narrow gap 197 is defined between the bezel 194 and the opening 198 around the perimeter of the bezel 194. As shown, with the faceplate 196 secured to the mechanical switch 190, the bezel 194 can protrude beyond an outer surface 199 of the faceplate 196. The outer surface 199 of the faceplate 196 can alternatively be referred to as a front surface of the faceplate 196.

[0048] According to the illustrated orientation of the mechanical switch 190, an upper portion of the toggle actuator 192 can define a first actuation surface 191 that can be pressed to operate the toggle actuator 192 from a second position to a first position (e.g., as shown by the arrow 193). The first actuation surface 191 can be referred to as a top surface of the toggle actuator 192. The first actuation surface 191 can be referred to as a top surface of the toggle actuator 192. Figure 2The lower portion of the rocker actuator 192 can define a second actuation surface 193 that can be pressed to operate the rocker actuator 192 from the first position to the second position. As shown, the first position of the rocker actuator 192 can correspond to an "on" position of the mechanical switch 190, which corresponds to the mechanical switch 190 allowing power from the AC power source to be delivered to the one or more electrical loads. With the rocker actuator 192 in the first position, the lower portion of the rocker actuator 192 can protrude outward relative to the bezel 194 and the faceplate 196. The lower portion of the rocker actuator 192 that protrudes outward relative to the bezel 194 and the faceplate 196 can be referred to as the protruding portion of the rocker actuator 192. It will be appreciated that in alternative configurations where the second position of the rocker actuator 192 corresponds to the first position of the mechanical switch 190, the upper portion of the rocker actuator 192 can protrude outward relative to the bezel 194 and the faceplate 196, and thus can be referred to as the protruding portion of the rocker actuator 192.

[0049] The load control system can also include a load control device (not shown) that is electrically connected to the one or more electrical loads (e.g., lighting loads). The load control device can include a load control circuit to control the intensity of one or more of the lighting loads between a low end intensity (e.g., about 1%) and a high end intensity (e.g., about 100%), and can include a wireless communication circuit. In an example implementation, the load control device can be a standalone dimmer switch that is electrically connected to the one or more lighting loads. In another example implementation, each of the one or more electrical loads can be a controllable light source (e.g., a screw-in light emitting diode (LED) lamp), which can each include a respective integrated load control circuit and wireless communication circuit (e.g., the electrical loads include corresponding load control devices configured for wireless communication). It will be appreciated that the load control system is not limited to the example load control devices described herein.

[0050] As shown, the example remote control device 100 can include a control unit 110 that can be mounted to a base 120. The base 120 can alternatively be referred to as a base portion or a mounting assembly. The control unit 110 and the base 120 can be configured such that the control unit 110 can be removably attached to the base 120. The base 120 can be attached to the rocker actuator 192 of the mechanical switch 190 without removing the faceplate 196. In this regard, the remote control device 100 can be mounted over an installed mechanical switch, such as the mechanical switch 190, without the need to remove the faceplate 196 and / or perform any electrical rewiring of the mechanical switch 190.

[0051] The control unit 110 can include a user interface that includes an actuation portion 112 that can be attached to the housing 114. The actuation portion 112 can include a front surface 115 having an upper portion 116 and a lower portion 118. The actuation portion 112 can be configured to pivot about a central axis in response to actuation of the upper portion 116 and the lower portion 118. The control unit 110 can be configured to control an electrical load. For example, the control unit 110 can be configured to turn the electrical load on in response to actuation of the upper portion 116 and turn the electrical load off in response to actuation of the lower portion 118. The front surface 115 of the actuation portion 112 can also be configured as a touch-sensitive surface (e.g., a capacitive touch surface) configured to receive (e.g., detect) input, such as gestures, from a user of the control unit 110. The control unit 110 can also include a light bar 119 configured to be illuminated by one or more light sources (e.g., one or more LEDs) to visually display information. The front surface 115 of the actuation portion 112 can be actuated along the light bar 119 to adjust an amount of power delivered to the electrical load according to a location of the actuation.

[0052] As shown, the base 120 can include a clamp arm 130 (e.g., a bar), a screw 140, and a frame 150. The frame 150 can include a plate 152 and an outer wall 154 extending from the plate 152. The outer wall 154 can extend from a perimeter of the plate 152. The outer wall 154 can include a first end wall 122, an opposite second end wall 124, and opposite side walls 126 extending from respective ends of the first end wall 122 to corresponding ends of the second end wall 124. The plate 152 can define a back surface 128 of the base 120.

[0053] The frame 150 can define an opening 156. For example, the opening 156 can be configured to receive a protruding portion of the rocker actuator 192 when the base 120 is installed over the mechanical switch 190. The frame 150 can at least partially enclose the rocker actuator 192 when the protruding portion of the rocker actuator 192 is received in the opening 156. The opening 156 can extend through about a lower half of the plate 152. The base 120 can define one or more teeth 144. The teeth 144 can extend into the opening 156. For example, the teeth 144 can extend into the opening 156 proximate the back surface 128 of the base 120. The teeth 144 can be configured to engage a side of the protruding portion of the rocker actuator 192.

[0054] The frame 150 can define a sleeve 142 configured to receive the screw 140. The sleeve 142 can include an internal threading that mates with a threading of the screw 140. The sleeve 142 can be positioned along the second end wall 124 of the outer wall 154. Although in the example shown in FIG. 1, the sleeve 142 is positioned along the second end wall 124 of the outer wall 154, the sleeve 142 can be positioned along any portion of the outer wall 154. For example, the sleeve 142 can be positioned along the first end wall 122 of the outer wall 154. Figures 1-8The sleeve 142 is biased toward the clamping arm 130, but it should be understood that the sleeve 142 may be located at the midpoint of the second end wall 124, biased toward the side wall 126 distal to the clamping arm 130, or at another location along the second end wall 124. The length of the screw 140 may be configured based on the position of the sleeve 142 along the second end wall 124. Although the sleeve 142 is positioned along the second end wall 124 of the frame 150, it should be understood that the sleeve 142 may be located at other locations on the base 120.

[0055] The outer wall 154 may define a plurality of attachment members 157. For example, each of the opposing sidewalls may include one or more attachment members 157. The attachment members 157 may be configured to engage corresponding feature structures of the housing 114 of the control unit 110, such that the control unit can be releasably attached to the base 120. The attachment members 157 may be snap-fit ​​(e.g., resilient snap-fit ​​connectors).

[0056] The clamping arm 130 may be configured to secure (e.g., attach) the base 120 to a protrusion of the rocker actuator 192 of the mechanical switch 190. The clamping arm 130 may abut the protrusion of the rocker actuator 192. For example, as shown, the clamping arm 130 may be configured to apply force to the protrusion of the rocker actuator 192 when the screw 140 is driven (e.g., further rotated) into the sleeve 142. The clamping arm 130 may define a hole 134 (e.g., as shown). Figure 8 As shown, the hole is configured to receive a screw 140. The head 141 of the screw 140 may be configured to abut a clamping arm 130 when the screw 140 is driven into the sleeve 142. The clamping arm 130 may include one or more teeth, such as... Figure 8 The tooth 132 is shown. The tooth 132 can extend from the clamp arm 130 into the opening 156. The tooth 132 can be configured to engage (e.g., bite) a protrusion of the rocker actuator 192. Although shown as having a triangular prism shape, it should be understood that the tooth 132 can define various shapes, such as cylindrical, conical, pyramidal, and / or another similar shape.

[0057] The clip arms 130 can be pivotally attached to the base 120. For example, the base 120 can define a tab 159 extending from an outer wall 154 of the base 120 (e.g., one of the sidewalls 126). The tab 159 can define a pivot joint 136 therethrough. The pivot joint 136 can be located near a midpoint of the frame 150. The clip arms 130 can be connected to the tab 159 at the pivot joint 136. The pivot joint 136 can be configured to enable the clip arms 130 to operate with the protruding portion of the rocker actuator 192 between a disengaged position and an engaged position. A screw 140 can be in operative engagement with the clip arms 130. For example, as the screw 140 is rotated within the sleeve 142, the clip arms 130 can pivot about the pivot joint 136 and move toward the protruding portion of the rocker actuator 192. The clip arms 130 can move toward the protruding portion of the rocker actuator 192 until the clip arms 130 abut the protruding portion.

[0058] The disengaged position can be defined as the clip arms 130 being located near the outer wall 154. The engaged position can be defined as the clip arms 130 being located distal from the outer wall 154 and / or above the opening 156. Clockwise rotation of the screw 140 can cause the clip arms 130 to pivot from the disengaged position to the engaged position. Counterclockwise rotation of the screw 140 can cause the clip arms 130 to pivot from the engaged position to the disengaged position. The pivot joint 136 can be a revolute joint (e.g., a pin joint or a hinge joint) having a pin extending through the tab 159 and the clip arms 130. The pivot joint 136 can be configured to enable the clip arms 130 to rotate about the pin (e.g., an axis defined by the pin). Alternatively, the pivot joint 136 can be a cylindrical joint, a spherical joint, a knuckle joint, or another similar joint.

[0059] According to the illustrated configuration of the base 120, the back surface 128 of the base 120 can be configured such that the back surface 128 of the base 120 abuts the bezel 194 and can not contact the outer surface 199 of the faceplate 196. It should be appreciated that the outer wall 154 of the base 120 is not limited to the illustrated geometry. For example, the base 120 can alternatively be configured such that the outer wall 154 encloses the bezel 194 and at least a portion of the back surface 128 of the base 120 abuts the outer surface 199 of the faceplate 196 when the base 120 is attached to the protruding portion of the rocker actuator 192. In another example, the base 120 can alternatively be configured such that the outer wall 154 encloses the faceplate 196 of the mechanical switch 190, e.g., such that the back surface 128 of the base 120 abuts a surface of a structure in which the mechanical switch 190 is installed, such as a surface of a wall.

[0060] The base 120 and the control unit 110 can be configured to enable the control unit 110 to be releasably attached to the base 120. For example, one or more components of the base 120 can include engagement features that can be configured to engage with complementary engagement features of the housing 114 of the control unit 110. As shown, the attachment member 157 can define a resilient snap-fit connector that can be configured to engage with complementary engagement features (not shown) defined on a corresponding inner surface of the control unit 110. In this regard, the frame 150 can be configured for releasably attaching the control unit 110 to the frame 150 via the attachment member 157.

[0061] The user interface of the control unit 110 (e.g., the actuation portion 112) can be configured to receive inputs, such as finger presses and / or gestures, from a user of the remote control 100. For example, in accordance with the illustrated configuration, the actuation portion 112 of the control unit 110 can be configured to pivot about a central axis in response to actuation of the respective upper and lower portions 116, 118 of the actuation portion 112 when the housing 114 is attached to the base 120. The front surface 115 of the actuation portion 112 can define a capacitive touch surface along the upper and lower portions 116, 118 that can be configured to detect touches along the x-axis, the y-axis, or both the x-axis and the y-axis.

[0062] The control unit 110 can include control circuitry (e.g., a processor, not shown) and wireless communication circuitry (e.g., an RF transceiver, not shown). The control unit 110 can be configured to convert one or more inputs (e.g., user inputs) from the user interface into respective control signals that can be used to control a load control device of a load control system. The one or more inputs can be applied via touches or presses of the upper and / or lower portions 116, 118 of the actuation portion 112. For example, the control circuitry can be configured to receive input signals (e.g., corresponding to the user inputs) in response to actuation of the upper and / or lower portions 116, 118 by a user of the remote control 100. For example, the input signals received by the control circuitry can be respective control signals converted from the user interface inputs. The control circuitry can be configured to generate commands that a user desires the control unit 110 to perform in response to the input signals generated in response to actuation of the upper and / or lower portions 116, 118. The control unit 110 can be configured to cause the wireless communication circuitry to transmit one or more control signals that include the commands generated by the control circuitry.

[0063] The light bar 119 of the control unit 110 can be configured to provide a visual indication of commands issued by the remote control 100. For example, the control circuit can be configured to indicate the amount of power delivered to an electrical load by temporarily illuminating a number of LEDs corresponding to the desired amount of power (e.g., a desired dimming level of a lighting load) upon receiving a gesture indicating a command to change the amount of power delivered to the electrical load, such as a command to dim a lighting load. In such examples, the control circuit can be configured to cause the LEDs to be illuminated simultaneously, sequentially with some or little overlap before dimming, or otherwise as desired. The control unit 110 can be configured to be attached to the base 120 with the light bar 119 on a predetermined side of the control unit (e.g., the right side of the control unit as shown in Figure 1 FIG. 1), for example, such that the light bar 119 can be illuminated to indicate the amount of power currently delivered to an electrical load.

[0064] The control circuit can be configured to cause the wireless communication circuit to transmit respective commands corresponding to inputs and / or gestures received by the upper portion 116 and / or the lower portion 118. For example, the remote control 100 can be operable to transmit wireless signals (e.g., radio frequency (RF) signals) to load control devices, one or more electrical loads, and / or a central processor of a load control system. During a configuration process of the load control system, the remote control 100 can be associated with the load control devices and the one or more electrical loads.

[0065] The control unit 110 can be battery powered. The housing 114 of the control circuit 110 can be configured to receive a battery (not shown) for powering the control unit 110 (e.g., as will be described in greater detail below with reference to Figures 16-24 The remote control 100 can optionally include a battery. For example, the control unit 110 can be configured to obtain power from an external power source (e.g., a power source connected to the mechanical switch 170, such as an AC power source or an external DC power source). The base 120 can include a power source, such as a battery external to the control unit 110. The base 120 can be configured to provide power from the battery to the control unit 110 when the control unit 110 is attached to the base 120. For example, the base 120 can include a battery printed circuit board (PCB) (not shown) that can be mounted to the board 152.

[0066] In an example process of attaching the base 120 to the rocker actuator 192 of the mechanical switch 190, the base 120 can be placed over the rocker actuator 192 such that the protruding portion of the rocker actuator extends through the opening 156. The clip arms 130 can be in the disengaged position when the base 120 is placed over the rocker actuator 192. The rear surface 128 of the base 120 can abut the outer surface 199 of the faceplate 196 and / or the bezel 194 of the mechanical switch 190 when the base 120 is placed over the rocker actuator 192. The screw 140 can be operated such that the threads of the screw 140 engage the internal threads of the sleeve 142. The clip arms 130 can pivot about the pivot joints 136 as the screw 140 is operated (e.g., clockwise) such that the clip arms 130 move toward the protruding portion of the rocker actuator 192. The clip arms 130 and / or the teeth 132, 144 can exert a force on the protruding portion of the rocker actuator 192 as the screw 140 is further operated (e.g., clockwise). For example, the teeth 132 and 144 can captively engage (e.g., bite into) the protruding portion of the rocker actuator 192 as the screw 140 is further operated. The base 120 can be secured to the protruding portion of the rocker actuator 192 when the teeth 132 and 144 captively engage (e.g., bite into) the protruding portion of the rocker actuator 192.

[0067] With the base 120 attached to the rocker actuator 192 (e.g., as shown in FIGS. 1A-1C), the control unit 110 can be attached to the base 120. For example, the housing 114 of the control unit 110 can be aligned with and pressed over the base 120. The housing 114 of the control unit 110 can engage the attachment member 157 defined on the outer wall 154 of the base 120 such that the control unit 110 is removably attached to the base 120. Figure 2 and Figure 3 With the base 120 attached to the rocker actuator 192 (e.g., as shown in FIGS. 1A-1C), the control unit 110 can be attached to the base 120. For example, the housing 114 of the control unit 110 can be aligned with and pressed over the base 120. The housing 114 of the control unit 110 can engage the attachment member 157 defined on the outer wall 154 of the base 120 such that the control unit 110 is removably attached to the base 120.

[0068] Figures 9-13 Another example base 220 of a remote control device (e.g., such as the example remote control device 100) that can be installed in a load control system, such as a lighting control system, is depicted. The load control system can include a mechanical switch, such as the mechanical switch 190, which can be in place prior to installation of the remote control device, e.g., pre-existing in the load control system. The load control system can also include one or more electrical loads, such as lighting loads. The mechanical switch 190 can be coupled in series electrical connection between an alternating current (AC) power source and the one or more electrical loads (not shown). The load control system can also include a load control device (not shown) that is electrically connected to the one or more electrical loads, as described herein.

[0069] As shown, the base 220 can include a clamp arm 230 (e.g., a bar), a screw 240, and a frame 250. The frame 250 can include a plate 252 and an outer wall 254 extending from the plate 252. The outer wall 254 can extend from a perimeter of the plate 252. The outer wall 254 can be discontinuous along the perimeter of the plate 252. For example, the outer wall 254 can include an end wall 222 and opposing side walls 226. The end wall 222 can not be connected to the opposing side walls 226. The base 220 (e.g., the plate 252) can define an edge 224 distal to the end wall 222. For example, the base 220 can define a terminal edge (e.g., the edge 224) extending between the end portions of the opposing side walls 226. The terminal edge of the base 220 can be distal to a midpoint of the mechanical switch 190. The plate 252 can define a back surface 228 of the base 220.

[0070] The frame 250 can define an opening 256. For example, the opening 256 can be configured to receive the protruding portion of the rocker actuator 192 when the base 220 is installed over the mechanical switch 190. The opening 256 can extend through about a lower half of the plate 252. The base 220 can define one or more teeth 244. The teeth 244 can extend into the opening 256. For example, the teeth 244 can extend into the opening 256 proximate to the back surface 228 of the base 220. The teeth 244 can be configured to engage a side of the protruding portion of the rocker actuator 192. The base 220 can define a sleeve 242 configured to receive the screw 240. The sleeve 242 can include internal threads that mate with threads of the screw 240. The sleeve 242 can be located proximate to the edge 224. Although the sleeve 242 is located proximate to the midpoint of the edge 224 of the base 220 in the example of FIG. 2, it should be understood that the sleeve 242 can be biased toward a side wall of the base (e.g., one of the opposing side walls 226 of the frame 250) that is distal to or proximate to the clamp arm 230, or at another location along the edge 224 of the base 220. The length of the screw 240 can be configured based on the location of the sleeve 242 along the edge 224 of the base 220. Although the sleeve 242 is positioned along the edge 224 of the base 220, it should be understood that the sleeve 242 is not limited to being located at the edge 224 of the base 220 and can be located at other locations of the base 220. Figures 9-13

[0071] ​The outer wall 254 can define a plurality of attachment members (not shown). For example, each of the opposing side walls can include one or more attachment members. The attachment members can be configured to engage corresponding features of a control unit (e.g., the control unit 110) such that the control unit can be releasably attached to the base 220. The attachment members can be resilient snap-fit connectors (e.g., snaps such as the attachment members 157 configured to engage corresponding features of the housing 114 of the control unit 110). The outer wall 254 of the base 220 can be configured to provide a friction fit with the control unit. For example, the outer wall 254 can be sized and / or can include one or more features such that corresponding walls and / or corresponding features of the housing 114 of the control unit are secured to the base 220 using friction.

[0072] The clip arms 230 can be configured to secure (e.g., attach) the base 220 to the protruding portion of the rocker actuator 192 of the mechanical switch 190. For example, as shown, the clip arms 230 can be configured to exert a force on the protruding portion of the rocker actuator 192 as the screw 240 is driven into the sleeve 242. The clip arms 230 can define holes 234 configured to receive the screw 240. The clip arms 230 can define plates 231. The distal end 241 of the screw 240 can be configured to abut the plates 231 of the clip arms 230 as the screw 240 is driven into the sleeve 242. For example, the distal end 241 of the screw 240 can exert a force on the plates 231 as the screw 240 is driven into the sleeve 242. The clip arms 230 can include one or more teeth, such as the teeth 232 shown. The teeth 232 can extend from the clip arms 230 into the openings 256. The teeth 232 can be configured to engage (e.g., bite into) the protruding portion of the rocker actuator 192. Although shown as having a triangular prismatic shape, it should be understood that the teeth 232 can define various shapes, such as a cylindrical shape, a conical shape, a pyramidal shape, and / or another similar shape. Figure 13

[0073] ​The clip arms 230 can be pivotally attached to the base 220. For example, the base 220 can define a pivot joint 236 therethrough. The pivot joint 236 can be located proximate the rim 224 of the frame 250. The clip arms 230 can be connected to the frame 250 (e.g., the plate 252) at the pivot joint 236. The pivot joint 236 can be configured to enable the clip arms 230 to operate with the protruding portion of the rocker actuator 192 between a disengaged position and an engaged position. For example, as the screw 240 is rotated within the sleeve 242, the clip arms 230 can pivot about the pivot joint 236. The disengaged position can be defined as the clip arms 230 being located proximate the outer wall 254. The engaged position can be defined as the clip arms 230 being located distal the outer wall 254 and / or over the opening 256. Clockwise rotation of the screw 240 can cause the clip arms 230 to pivot from the disengaged position to the engaged position. Counterclockwise rotation of the screw 240 can cause the clip arms 230 to pivot from the engaged position to the disengaged position. The pivot joint 236 can be a revolute joint (e.g., such as a pin joint or a hinge joint) having a pin extending through the clip arms 230 and the base 220. The pivot joint 236 can be configured to enable the clip arms 230 to rotate about the pin (e.g., an axis defined by the pin). Alternatively, the pivot joint 236 can be a cylindrical joint, a spherical joint, a knuckle joint, or another similar joint.

[0074] According to the illustrated configuration of the base 220, the frame 250 can be configured such that the rear surface 228 of the base 220 abuts the bezel 194 and can not contact the outer surface 199 of the faceplate 196. It should be appreciated that the outer wall 254 of the frame 250 is not limited to the illustrated geometry. For example, the frame 250 can alternatively be configured such that the outer wall 254 encloses the bezel 194 and at least a portion of the rear surface 228 of the base 220 abuts the outer surface 199 of the faceplate 196 when the base 220 is attached to the protruding portion of the rocker actuator 192. In another example, the frame 250 can alternatively be configured such that the outer wall 254 encloses the faceplate 196 of the mechanical switch 190, e.g., such that the rear surface 228 of the base 220 abuts a surface of a structure in which the mechanical switch 190 is installed, such as a surface of a wall.

[0075] The base 220 and the control unit can be configured to enable the control unit to be releasably attached to the base 220. For example, one or more components of the base 220 can include an engagement feature that can be configured to engage with a complementary engagement feature of the control unit.

[0076] In an exemplary process of attaching the base 220 to the rocker actuator 192 of the mechanical switch 190, the base 220 can be placed over the rocker actuator 192 such that the protruding portion of the rocker actuator extends through the opening 256. The clip arms 230 can be in the disengaged position when the base 220 is placed over the rocker actuator 192. The rear surface 228 of the base 120 can abut the outer surface 199 of the faceplate 196 and / or the bezel 194 of the mechanical switch 190 when the base 220 is placed over the rocker actuator 192. The screw 240 can be operated such that the threads of the screw 240 engage the internal threads of the sleeve 242. When the screw 240 is operated (e.g., clockwise), the distal end 241 of the screw 240 can abut the plate 231 of the clip arm 230 and the clip arm 230 can pivot about the pivot joint 236 such that the clip arm 230 moves toward the protruding portion of the rocker actuator 192. As the screw 240 is further operated (e.g., clockwise), the clip arm 230 can abut the protruding portion of the rocker actuator 192. The clip arm 230 and / or the teeth 232, 244 can exert a force on the protruding portion of the rocker actuator 192. For example, as the screw 240 is further operated, the teeth 232 and 244 can captively engage (e.g., bite into) the protruding portion of the rocker actuator 192. When the teeth 232 and 244 captively engage (e.g., bite into) the protruding portion of the rocker actuator 192, the base 220 can be secured to the protruding portion of the rocker actuator 192.

[0077] With the base 220 attached to the rocker actuator 192 (e.g., as shown in FIGS. 2A and 2B), the control unit can be attached to the base 220. For example, the control unit 110 can be aligned with and pressed over the base 220. The housing 114 of the control unit 110 can engage the attachment member defined on the outer wall 254 of the base 220 such that the control unit 110 is removably attached to the base 220. Alternatively, the walls of the housing 114 of the control unit 110 can engage the outer wall 254 of the base 220 such that friction secures the control unit 110 to the base 220. Figure 9 and Figure 10 With the base 220 attached to the rocker actuator 192 (e.g., as shown in FIGS. 2A and 2B), the control unit can be attached to the base 220. For example, the control unit 110 can be aligned with and pressed over the base 220. The housing 114 of the control unit 110 can engage the attachment member defined on the outer wall 254 of the base 220 such that the control unit 110 is removably attached to the base 220. Alternatively, the walls of the housing 114 of the control unit 110 can engage the outer wall 254 of the base 220 such that friction secures the control unit 110 to the base 220.

[0078] Figures 14-18Another exemplary remote control device 300 is depicted that can be installed in a load control system such as a lighting control system. The load control system may include mechanical switches, such as mechanical switch 190, which may be in place before the remote control device 300 is installed, for example, pre-existing in the load control system. The load control system may also include one or more electrical loads, such as lighting loads. Mechanical switch 190 may be coupled in series electrical connection between an alternating current (AC) power source and one or more electrical loads (not shown), such as a controllable light source. The load control system may also include one or more load control devices (not shown) electrically connected to and / or integrated with one or more electrical loads, as described herein.

[0079] As shown in the figure, the exemplary remote control device 300 may include a control unit 310 and a base 320 (e.g., such as...). Figures 2-8 The base 120 or depicted in the text Figures 9-13 The base 220 depicted in the diagram operates as a mounting component for the control unit 310. The base 320 may also be alternatively referred to as a base portion or mounting assembly. The control unit 310 and the base 320 may be configured such that the control unit 310 can be removably attached to the base 320. The base 320 can be attached to the rocker actuator 192 of the mechanical switch 190 without removing the panel 196. In this respect, the remote control device 300 can be mounted above an already installed mechanical switch (such as mechanical switch 190) without removing the panel 196 and / or performing any electrical rewiring of the mechanical switch 190.

[0080] Control unit 310 may be configured to function similarly to control unit 110. For example, control unit 310 may include a user interface including an actuation portion 312 that can be attached (e.g., fixedly attached) to housing 314. Actuation portion 312 may include a front surface 315 having an upper portion 316 and a lower portion 318. The front surface 315 of actuation portion 312 may be configured as a touch-sensitive surface (e.g., a capacitive touch surface) configured to receive (e.g., detect) input from a user of control unit 310, such as touch or gesture. Control unit 310 may be configured to control an electrical load to turn on the electrical load in response to actuation (e.g., touch) of the upper portion 316 and to turn off the electrical load in response to actuation (e.g., touch) of the lower portion 318. Control unit 310 may also include a light strip 319 configured to be illuminated by one or more light sources (e.g., one or more LEDs) to visually display information. Light strip 319 may be biased toward one side of control unit 310. The control unit 310 can be configured to adjust the amount of electricity delivered to the electrical load in response to actuation (e.g., touch) along the light bar 319 (e.g., depending on the location of actuation along the light bar).

[0081] The control unit 310 can be battery powered. The control unit 310 can be configured to receive a battery 360 to power the electrical circuitry of the control unit 310. For example, the control unit 310 can define a void 330. For example, a rear surface 332 of the control unit 310 can define the void 330. The void 330 can be configured to receive a PCB 340 of the remote control device 300. The control unit 310 can include a battery holder 362 (e.g., a battery clip). The battery holder 362 can be electrically conductive and can be mounted to the PCB 340. The PCB 340 can include one or more electrical contacts (e.g., such as electrical contact pads 374, 376). The battery holder 362 can define a first arm 364, a second arm 366, and a mounting flange 368. The first arm 364 can extend from the mounting flange 368 in a first direction. The second arm 366 can extend from the mounting flange 368 in a second direction. The second direction can be opposite the first direction. The first arm 364 and the second arm 366 can be compliant members. For example, the first arm 364 and the second arm 366 can be biased toward the PCB 340 such that they are configured to exert a force on the battery 360 to secure the battery 360 within the battery holder 360.

[0082] The battery holder 362 can be configured to receive a single battery (e.g., the battery 360) in one of two positions to power the electrical circuitry of the control unit 310. The first arm 364 can be configured to secure the battery 360 in a first position within the battery holder 362. The second arm 366 can be configured to secure the battery 360 in a second position within the battery holder 362. For example, the first position can be defined as the first arm 364 securing the battery 360 against the electrical contact pad 374, for example as shown in Figure 16 The second position can be defined as the second arm 366 securing the battery 360 against the electrical contact pad 376. The first arm 364 can operate as an electrical contact when the battery 360 is secured against the electrical contact pad 374, and the second arm 366 can operate as an electrical contact when the battery 360 is secured against the electrical contact pad 376. The mounting flange 368 can be configured to attach (e.g., mechanically couple and electrically couple) the battery holder 362 to the PCB 340. Each of the mounting flanges 368 can be fastened to the PCB 340, for example using fasteners, solder, adhesive, etc. For example, the battery 360 can be coupled to the electrical circuitry of the control unit 310 through the PCB 340 (e.g., via the battery holder 362 and / or the electrical contact pads 374, 376).

[0083] The control unit 310 can be configured to attach to the base 320 with the light bar 319 on a predetermined side of the control unit (e.g., as shown in Figure 14on the right side of the control unit 310, such that the light bar 319 can be illuminated to indicate, for example, the amount of power currently being delivered to an electrical load. The control unit 310 can be configured to attach to the base 320 with the light bar 319 on a predetermined side of the control unit, independent of the position of the paddle actuator 192 of the mechanical switch 190 (e.g., whether the upper portion or the lower portion of the paddle actuator 192 protrudes from the bezel 194).

[0084] The battery 360 can be configured to be installed in the control unit 310 based on the position of the paddle actuator 192 when power is being delivered to an electrical load associated with the mechanical switch 190. The battery 360 can be installed within the battery holder 362 in an orientation that corresponds to the position of the mechanical switch 190. For example, the battery 360 can be installed in a first position (e.g., secured against the electrical contact pad 374) using the first arm 364. The first position can correspond to the upper portion of the paddle actuator 192 protruding into the void 330 (e.g., as Figure 18 depicted). The battery 360 can be installed in a second position (e.g., secured against the electrical contact pad 376) using the second arm 366. The second position can correspond to the lower portion of the paddle actuator 192 protruding into the void 330.

[0085] The base 320 can be configured to be secured to the protruding portion of the paddle actuator 192 (e.g., such as the base 120 and / or the base 220). When the base 320 is secured to the protruding portion of the paddle actuator 192, the rear surface of the base 320 can be biased against the bezel 194 of the mechanical switch 190. With the base 320 attached to the paddle actuator 192 (e.g., as Figure 15 depicted), the control unit 310 can be attached to the base 320.

[0086] The base 320 can be configured to enable the control unit 310 to be releasably attached to the base 320. For example, one or more components of the base 320 can include engagement features (e.g., such as the attachment member 157 of the control unit 110) that can be configured to engage with complementary engagement features of the control unit 310. For example, the control unit 310 can define a snap 325 (e.g., a resilient snap-fit connector). The snap 325 can extend into the void 330. The snap 325 can be configured to secure the control unit 310 to the base 320.

[0087] Figures 19-24 Another remote control device 400 is depicted having a control unit 410 with an alternative battery holder 462. The control unit 410 can have the same or similar user interface as the user interface of the control unit 310, as Figure 14 depicted. The control unit 410 can be installed to a base 420 (e.g.,Figures 2-8 The base 120 or Figures 9-13 The base 220). The base 420 can alternatively be referred to as a base portion or a mounting assembly. The control unit 410 and the base 420 can be configured such that the control unit 410 can be removably attached to the base 420. The base 420 can be attached to the rocker actuator 192 of the mechanical switch 190 without removing the faceplate 196. In this regard, the remote control device 400 can be installed over an already installed mechanical switch, such as the mechanical switch 190, without the need to remove the faceplate 196 and / or perform any electrical rewiring of the mechanical switch.

[0088] The base 420 can be configured to enable the control unit 410 to be releasably attached to the base 420. For example, one or more components of the base 420 can include engagement features (e.g., the attachment members 157 of the control module 110) that can be configured to engage with complementary engagement features of the control unit 410. For example, the control unit 410 can define a snap (e.g., a resilient snap-fit connector). The snap can be configured to secure the control unit 410 to the base 420.

[0089] The control unit 410 can be battery powered. The control unit 410 can be configured to receive a battery 460 in order to power the electrical circuitry of the control unit 410. For example, the control unit 410 can define a void 430. For example, the rear surface 416 of the control unit 410 can define the void 430. The void 430 can be configured to receive a PCB 440 of the remote control device 400. The PCB 440 can include one or more electrical contact pads (e.g., the electrical contact pads 474). A battery holder 462 of the control unit 410 can be electrically conductive and can be mounted to the PCB 440. The battery holder 462 can define mounting flanges 468 and electrical contact members 466. The electrical contact members 466 can extend between the mounting flanges 468 to define a slot 469. The slot 469 can be defined by the electrical contact members 466, the mounting flanges 468, and the PCB 440. The slot 469 can be configured to receive the battery 460 therein.

[0090] Battery holder 462 (e.g., electrical contact member 466) may further define one or more orifices 465 and one or more tabs 464. Tabs 464 may be located at orifices 465. Tabs 464 may extend into slots 469. Tabs 464 may be located approximately at the midpoint of PCB 440, for example, such that tabs 464 are configured to engage battery 460 when battery 460 is mounted within battery holder 462. Battery holder 462 may be configured to hold battery 460 against electrical contact pad 474. Tabs 464 may be configured to prevent battery 460 from being mounted in battery holder 462 beyond a predefined position. For example, tabs 464 may be configured such that battery 460 does not interfere with rocker actuator 192 of mechanical switch 190 when mounted.

[0091] Mounting flanges 468 can be configured to attach (e.g., mechanically and electrically) battery holder 462 to PCB 440. Each mounting flange in mounting flanges 468 can be fastened to PCB 440, for example, using fasteners, solder, adhesive, etc. For example, battery 460 can be coupled to the electrical circuitry of control unit 410 via PCB 440 (e.g., via battery holder 462 and / or electrical contact pad 474).

[0092] Control unit 410 may include light strips (e.g., Figure 14 The control unit 310 shown has an LED strip 319. The LED strip can be biased to one side of the control unit 410. The control unit 410 can be configured to be attached to the base 420 with the LED strip located on a predetermined side (e.g., the right side) of the control unit, such that the LED strip can be illuminated to indicate, for example, the amount of electricity currently delivered to an electrical load. The control unit 410 can be configured to be attached to the base 420 with the LED strip located on a predetermined side of the control unit, regardless of the position of the rocker actuator 192 of the mechanical switch 190 (e.g., whether the upper or lower portion of the rocker actuator 192 protrudes from the frame 194).

[0093] The battery holder 462 can be configured to receive a single battery (e.g., battery 460) in one of two positions in order to power the electrical circuitry of the control unit 410. The battery 460 can be configured to be installed in the control unit 410 based on the position of the rocker actuator 192 when power is delivered to the electrical load associated with the mechanical switch 190. The battery 460 can be installed within the battery holder 462 in an orientation that corresponds to the position of the mechanical switch 190. For example, the electrical contact member 466 can define a first edge 461 and a second edge 463. The second edge 463 can be opposite the first edge 461, for example, on an opposite side of the electrical contact member 466. The battery 460 can be installed into a first position from the first edge 461 of the electrical contact member 466. For example, the battery holder 462 can receive the battery into the slot 469 from the first edge 461. The first position can correspond to an upper portion of the rocker actuator 192 protruding into the void 430 (e.g., as shown in FIGS. Figure 21 and Figure 23 The battery 460 can be installed into a second position from the second edge 463 of the electrical contact member 466. For example, the battery holder 462 can receive the battery into the slot 469 from the second edge 463. The second position can correspond to a lower portion of the rocker actuator 192 protruding into the void 430 (e.g., as shown in FIGS. Figure 22 and Figure 24 The battery 460 can be installed into a second position from the second edge 463 of the electrical contact member 466. For example, the battery holder 462 can receive the battery into the slot 469 from the second edge 463. The second position can correspond to a lower portion of the rocker actuator 192 protruding into the void 430 (e.g., as shown in FIGS.

[0094] The electrical contact member 466 can be configured to provide electrical contact to the battery 460 when installed in the first position or the second position. For example, the electrical contact member 466 can be biased toward the PCB 440 such that the electrical contact member 466 exerts a force on the battery 460. The electrical contact member 466 can define a protrusion 467 configured to extend into the slot 469 toward the PCB 440. The protrusion 467 can be configured to abut the battery 460. The protrusion 467 can be configured to secure the battery 460 within the battery holder 462 (e.g., the slot 469). The protrusion 467 can be configured to provide electrical contact to the battery 460.

[0095] The base 420 can be configured to be secured to a protruding portion of the rocker switch actuator 192 (e.g., such as the base 120 and / or the base 220). When the base 420 is secured to the protruding portion of the rocker switch actuator 192, a rear surface of the base 420 can be biased against the bezel 194 of the mechanical switch 190. With the base 420 attached to the rocker switch actuator 192 (e.g., as shown in Figure 23 and Figure 24 The control unit 410 can be attached to the base 420.

[0096] Figures 25-32 Another example remote control device 500 that can be installed in a load control system, such as a lighting control system, is depicted. The load control system can include a mechanical switch, such as the mechanical switch 190, which can be in place prior to installation of the remote control device 500, e.g., pre-existing in the load control system. The load control system can also include one or more electrical loads, such as lighting loads. The mechanical switch 190 can be coupled in series electrical connection between an alternating current (AC) power source and one or more electrical loads (not shown), such as controllable light sources. The load control system can also include one or more load control devices (not shown) that are electrically connected to and / or integral with the one or more electrical loads, as described herein.

[0097] As shown, the example remote control device 500 can include a control unit 510, a cover portion 530 (e.g., a mounting adapter), and a cover base 520 (e.g., a first base). Additionally, the remote control device 500 can include a control base 515 (e.g., a second base) that is operable as a mount for the control unit 510. The control base 515 can alternatively be referred to as a first base, a second base, a control base portion, and / or a control mounting assembly. The control unit 510 and the control base 515 can be configured such that the control unit 510 can be removably attached to the control base 515. The control unit 510 can alternatively be referred to as a control module. It will be appreciated that other control units described herein can similarly alternatively be referred to as control modules.

[0098] The control unit 510 can include a user interface that includes a rotation portion 512 and an actuation portion 514. The rotation portion 512 can be rotatable relative to the control base 515. For example, as shown, the control unit 510 includes a ring-shaped rotation portion 512 that is configured to rotate about the control base 515. The remote control device 500 can be configured such that the control unit 510 and the control base 515 are removably attachable to one another. Figure 30 The remote control device 500 is depicted with the control unit 510 separated from the control base 515. When the control unit 510 is attached to the control base 515 (e.g., as shown in Figure 25As shown, the rotation portion 512 can be capable of rotating in an opposite direction about the control base 515, e.g., in a clockwise or counterclockwise direction. The control base 515 can be configured to be mounted above a light switch such that application of rotational motion to the rotation portion 512 does not actuate the light switch.

[0099] The actuation portion 514 can operate separately or in conjunction with the rotation portion 512. As shown, the actuation portion 514 can include a circular surface within an opening defined by the rotation portion 512. In an example implementation, the actuation portion 514 can be configured to move inward toward a light switch to actuate a mechanical switch (not shown) inside the control unit 510, e.g., as described herein. The actuation portion 514 can be configured to return to an idle or rest position (e.g., as shown) after being actuated. Figure 25 In this regard, the actuation portion 514 can be configured to operate as a toggle control of the control unit 510.

[0100] The remote control device 500 can be configured to transmit one or more wireless communication signals (e.g., RF signals) to one or more control devices. The remote control device 500 can include wireless communication circuitry, e.g., an RF transceiver or transmitter (not shown), via which the one or more wireless communication signals can be sent and / or received. The control unit 510 can be configured to transmit digital messages (e.g., including commands) in response to one or more actuations applied to the control unit 510, such as operation of the rotation portion 512 and / or the actuation portion 514. The digital messages can be transmitted to one or more devices associated with the remote control device 500, such as a controllable light source. For example, the control unit 510 can be configured to transmit a command to increase an intensity of a controllable light source via one or more RF signals in response to a clockwise rotation of the rotation portion 512, and to transmit a command to decrease the intensity of the controllable light source in response to a counterclockwise rotation of the rotation portion 512. The control unit 510 can be configured to transmit a command to toggle the controllable light source (e.g., from off to on, or vice versa) in response to actuation of the actuation portion 514. Additionally, the control unit 510 can be configured to transmit a command to turn the controllable light source on (e.g., if the control unit 510 knows that the controllable light source is presently off) in response to actuation of the actuation portion 514. The control unit 510 can be configured to transmit a command to turn the controllable light source off (e.g., if the control unit 510 knows that the controllable light source is presently on) in response to actuation of the actuation portion 514.

[0101] As described herein, the remote control device 500 can include a battery (not shown) for powering at least the remote control device 500. The remote control device 500 can be configured to enable the control unit 510 to be releasably attached to the control base 515. For example, the control base 515 can include a release mechanism that can be actuated to release the control unit 510 from the control base 515. For example, the control unit 510 can include two tabs (not shown) that are configured to snap onto corresponding attachment clips 513 on the control base 515. The control unit 510 can be installed on the control base 515 by pushing the control unit toward the control base 515 until the tabs of the control unit 510 engage the attachment clips 513. The control unit 510 can be released from the control base 515 by pulling the control unit 510 away from the control base 515. Additionally, the control base 515 can include a slide release tab that can be actuated to release the control unit 510 from the control base 515.

[0102] The remote control device 500 can be configured to be installed over the rocker actuator 192 (e.g., instead of a paddle actuator). The cover portion 530 can be configured to cover the actuator of the mechanical switch and receive the control base 515. For example, the control base 515 can be attached (e.g., releasably attached) to the cover portion 530. The cover base 530 can define an opening 517 for allowing the cover base 530 to be attached to the cover portion 530 (e.g., as will be described in more detail below). The cover portion 530 can be configured to releasably retain the control base 515. The cover portion 530 can define a front surface 532 and a rear surface 534. The cover portion 530 can include a mounting tab 535 extending from the front surface 532. The mounting tab 535 can be configured to be received in the opening 517 of the control base 515. The mounting tab 535 can be configured to prevent rotation of the control base 515 when the control base 515 is attached to the cover portion 530 and the rotary portion 512 is rotated. The cover portion 530 can include one or more tabs 536 extending from the rear surface 534. The one or more tabs 536 can be configured to secure the cover portion 530 to the cover base 520. Although the control base 515 is shown as being separate from the cover portion 530 in the figures, it should be understood that the control base 515 can be configured to be an integral part of the cover portion 530. For example, the cover portion 530 can include the control base 515. In other words, the control base 515 can be a part of the cover portion 530.

[0103] The cover base 520 can be configured to releasably retain the cover portion 530 when the control base 515 is attached to the cover portion 530. The cover base 520 can include a frame 522 and an engagement mechanism 524. The frame 522 can be configured to be mounted over the actuator 192 of the mechanical switch 190. The frame 522 can include a frame opening 523 extending therethrough. The frame opening 523 can be configured to receive a portion of the actuator 192.

[0104] The engagement mechanism 524 can be configured to secure the cover base 520 to the actuator 192. For example, the engagement mechanism 524 can secure the cover base 520 in a mounted position relative to the actuator 192. The engagement mechanism 524 can bias the back surface 531 against the outer surface 199 of the faceplate 196 such that the actuator 192 is held in a first position in which power is delivered to the electrical load. The engagement mechanism 524 can be operable to contact a first side 185 of the actuator 192 such that an opposite second side 195 of the actuator 192 is biased against a corresponding inner wall 526 of the frame 522. The inner wall 526 can define (e.g., partially define) the frame opening 523. The inner wall 526 can include one or more teeth (e.g., such as a tooth 527). The tooth 527 can be configured to abut the opposite second side 195 of the actuator 192.

[0105] The engagement mechanism 524 can include a clamp arm 550 (e.g., a lever), for example as shown in Figure 26 and Figures 28-30 The clamp arm 550 can extend into the frame opening 523. A first end 551 of the clamp arm 550 can be supported by the frame 522. A second end 552 of the clamp arm 550 can be translatable toward a center of the frame opening 523 (e.g., toward the inner wall 526). For example, the first end 551 can be pivotally supported by the frame 522 such that the second end 552 is configured to move toward (e.g., and away from) the inner wall 526. For example, the cover base 520 can define a pivot joint 554. The pivot joint 554 can be located proximate the frame opening 523. The clamp arm 550 can be connected to the frame 522 at the pivot joint 554.

[0106] The engagement mechanism 524 can include a screw 560. The screw 560 can operably connect the second end 552 of the clamp arm 550 to the frame 522, for example via a sleeve 562. The sleeve 562 can be attached to the cover base 520 (e.g., the frame 522). The screw 560 can be configured to translate the clamp arm 550 toward (e.g., and away from) the inner wall 526. For example, driving the screw 560 (e.g., clockwise) can cause the second end 552 of the clamp arm 550 to travel toward the inner wall 526. Driving the screw 560 in the opposite direction (e.g., counterclockwise) can cause the second end 552 of the clamp arm 550 to travel away from the inner wall 526.

[0107] Pivot joint 554 can be configured to enable clamping arm 550 to operate with the protruding portion of rocker actuator 192 between a disengaged position and an engaged position. For example, upon rotation of screw 560, clamping arm 550 can pivot about pivot joint 554. The disengaged position can be defined as clamping arm 550 not being in contact with actuator 192. The engaged position can be defined as clamping arm 550 being in contact with actuator 192. Clockwise rotation of screw 560 can cause clamping arm 550 to pivot from the disengaged position to the engaged position. Counterclockwise rotation of screw 560 can cause clamping arm 550 to pivot from the engaged position to the disengaged position.

[0108] Pivot joint 554 can be a revolute joint (e.g., such as a pin joint or a hinge joint) having a pin extending through clamping arm 550 and frame 522. Pivot joint 554 can be configured to enable clamping arm 550 to rotate about the pin (e.g., an axis defined by the pin). Alternatively, pivot joint 554 can be a cylindrical joint, a spherical joint, a knuckle joint, or another similar joint.

[0109] Clamping arm 550 can define an edge 553 facing a center of frame opening 523. Edge 553 (e.g., at least a portion of edge 553) can be configured to abut first side 185 of actuator 192. For example, upon translation of second end 552 of clamping arm 550 toward the center of frame opening 523, edge 553 can abut first side 185 of actuator 192. Edge 553 can include a tooth 556 (e.g., one or more teeth). Tooth 556 can extend from edge 553 toward the center of frame opening 523. Tooth 556 can engage first side 185 of actuator 192 (e.g., when clamping arm 550 is in the engaged position).

[0110] Frame 522 can define one or more slots 528. Slots 528 can be configured to receive corresponding tabs 536 extending from a rear surface 534 of cover portion 530, for example, to secure cover portion 530 to cover base 520.

[0111] Cover base 520 (e.g., frame 522) can include a plate 521 and a cradle 525. Plate 521 can be metal. Plate 521 can define frame opening 523. Clamping arm 550 can be attached to plate 521, for example, via pivot joint 554. Cradle 525 can be attached to plate 521, for example, via fasteners 529. Cradle 525 can be plastic. Cradle 525 can be configured to conceal (e.g., cover) at least a portion of plate 521 from view.

[0112] The remote control device 500 can include a fastener 580. The fastener 580 can be configured to secure the remote control device 500 (e.g., the control base 515) to the cover portion 530. For example, the fastener 580 can be configured to secure the control base 515 to a platform 570 that extends from the front surface 532 of the cover portion 530. A mounting tab 535 can extend from the platform 570. As previously described, the mounting tab 535 can be configured to be received in the opening 517 of the control base 515 to prevent rotation of the control base 515 when the control base 515 is attached to the cover portion 530 and the rotary portion 512 is rotated. The platform 570 can define an aperture 572. The aperture 572 can receive the fastener 580, for example, to secure the remote control device 500 (e.g., the control base 515) to the cover portion 530. The aperture 572 can be threaded. The control base 515 can include a through-hole 519 configured to receive the fastener 580. When the remote control device 500 is secured to the cover portion 530, the rear surface of the control base 515 can abut the front surface 532 of the cover portion 530.

[0113] It should be appreciated that the cover base 520 is not limited to the respective configurations illustrated and described herein. For example, the cover base 520 can be configured to allow releasable attachment of a control unit (e.g., such as the control units 110, 210, 310, and 410).

[0114] It should be appreciated that the bases 120, 220, 320, 420, and 520 are not limited to the respective configurations illustrated and described herein, and respective components of the bases can alternatively be configured with other suitable geometries. For example, the respective bases 120, 220, 320, 420, and 520 can alternatively be configured such that their outer walls bound a larger or smaller area. To illustrate, the outer wall of one or more of the bases 120, 220, 320, 420, and 520 can be configured to bound an area that is smaller than the footprint of the rocker actuator 192 of the mechanical switch 190, which can allow the faceplate 196 to be removed without interfering with the frame or requiring it to be separated from the rocker actuator 192. Additionally, it should be appreciated that the respective clip arms 130, 230, 550 of the bases 120, 220, 520 are not limited to the respective configurations illustrated and described herein, and can alternatively be configured with other suitable geometries, for example, to define alternative engagement surfaces.

[0115] It should be further understood that one or more of the bases 120, 220, 320, 420, and 520 can alternatively be configured to permit releasable attachment of control units having different geometries than those of the illustrated control units. To illustrate, one or more of the bases 120, 220, 320, 420, and 520 can alternatively be configured to permit releasable attachment of control units having a respective footprint (e.g., area) that is larger than a corresponding footprint of the base, e.g., such that the control unit encloses and / or at least partially conceals the frame from view. Additionally, one or more of the bases 120, 220, 320, 420, and 520 can alternatively be configured to permit releasable attachment of control units other than the illustrated control units 110, 210, 310, 410, and 510, e.g., such as control units having different geometries and / or defining other types of user interfaces.

[0116] It should be further understood that configuring a base of a remote control device such that a frame of the base is biased against a bezel of a mechanical switch to which the base is mounted (e.g., in accordance with the bases 120, 220, 320, 420, and 520 illustrated and described herein) can provide one or more advantages. For example, so configuring a base can limit or reduce the need to account for variables in one or more of lateral (e.g., edge-to-edge), longitudinal (e.g., up and down), and transverse (e.g., along a direction perpendicular to an outer surface of a faceplate) directions that can be exhibited by respective dimensions or geometries (e.g., paddle height) of different mechanical switches and / or installation conditions of the mechanical switches. Additionally, so referencing a base to a bezel of a mechanical switch, e.g., rather than to an outer surface of a faceplate, can eliminate the need to account for a frame that encloses a bezel of a mechanical switch, as bezel dimensions can vary from switch to switch.

[0117] It should be further understood that any of the example remote control devices 100, 200, 300, 400, and 500 illustrated and described herein can provide a simple retrofit solution for an existing switch control system and can simplify installation of a load control system, or augment an existing load control system installation. For example, a load control system that incorporates one of the remote control devices 100, 200, 300, 400, or 500 can provide energy saving and / or advanced control features without requiring any electrical rewiring and / or without requiring replacement of any existing mechanical switches.

[0118] It should be further understood that the example remote control devices 100, 200, 300, 400, and / or 500 can be integrated into load control systems that are not limited to the example load control devices and / or electrical loads described above. For example, the load control systems into which the remote control devices 100, 200, 300, 400, and / or 500 can be integrated can include one or more of the following: a dimming ballast for driving a gas discharge lamp; a light emitting diode (LED) driver for driving an LED light source; a dimming circuit for controlling the intensity of a lighting load; a screw-in lighting device including a dimmer circuit and an incandescent or halogen lamp; a screw-in lighting device including a ballast and a compact fluorescent lamp; a screw-in lighting device including an LED driver and an LED light source; an electronic switch, controllable breaker, or other switching device for switching a household appliance on and off; a plug-in load control device, controllable electrical outlet, or controllable power strip for controlling one or more plug-in loads; a motor control unit for controlling a motorized load, such as a ceiling fan or an exhaust fan; a drive unit for controlling a motorized window treatment or projection screen; one or more motorized interior and / or exterior blinds; a thermostat for a heating and / or cooling system; a temperature control device for controlling a set point temperature of a heating, ventilation, and air conditioning (HVAC) system; an air conditioner; a compressor; an electric foot warmer heater controller; a controllable damper; a variable air volume controller; a fresh air intake controller; a ventilation controller; a hydraulic valve for use in one or more radiators of a radiant heating system; a humidity control unit; a humidifier; a dehumidifier; a water heater; a boiler controller; a pool pump; a refrigerator; a freezer; a television and / or computer monitor; a video camera; an audio system or amplifier; an elevator; a power supply; a generator; a charger, such as an electric vehicle charger; an alternative energy controller; etc.
