[0008] The electrical equipment 1' for an electrical installation suitable and intended to be connected to an electrical network, includes at least: a reception module 8 comprising at least a first reception zone 9 ( figures 3A à 4 ); a primary functional module 2 received in the first reception zone 9 and comprising a first connection pole 3 capable and intended to be connected to a first line L of the electrical network, a second connection pole 4 capable and intended to be connected to a second line L1 of an electrical circuit of the electrical installation and a sixth connection pole 26. ( figure 1B ), the primary functional module 2 ( figures 1A et 1C ) comprising a current interrupting device 2" arranged between the first connection pole 3 and the sixth connection pole 26 and capable, in an open position, of interrupting the current between the first connection pole 3 and the sixth connection pole 26 and, in a closed position, of allowing the passage of current between the first connection pole 3 and the sixth connection pole 26 ( figures 1A, 1C And 5), electrical apparatus 1' characterized in that the reception module comprises a second reception zone 9' for receiving an additional functional module 5 ( figure 3A ) comprising means for performing at least one function requiring an electrical power supply, the additional functional module 5 comprising at least a fourth connection pole 6 and a fifth connection pole 7 capable of being electrically connected respectively to the second connection pole 4 and to the sixth connection pole 26 of the primary functional module 2 to power the additional functional module 5, and in that either the electrical apparatus 1' comprises a first blocking element being capable of blocking the interruption device 2" in the closed position when the additional functional module 5 is received in the second reception zone 9', or a first blocking element of the additional functional module 5 is capable of blocking the interruption device 2" in the closed position when the additional functional module 5 is received in the second reception zone 9'.

[0009] The first blocking element can therefore either be present on the apparatus 1' or on the additional functional module 5. In both cases, the first blocking element is arranged to be able to block the interruption device 2" in the closed position when the additional functional module 5 is received in the second reception zone 9'.

[0010] Said primary functional module 2 may comprise at least a first connection terminal 3' connected to the second connection pole 3 and a second connection terminal 4' connected to the sixth connection pole 26, the first connection terminal 3' and the second connection terminal 4' being able to form a first socket.

[0011] According to an alternative possibility, said primary functional module 2 may comprise at least a first conductive wire connected to the first connection pole 3 and a second conductive wire connected to the sixth connection pole 26, the first conductive wire and the second conductive wire being able to be connected to a terminal block of the additional functional module 5.

[0012] Said electrical apparatus 1' may further comprise a control member 2' capable of acting on the interruption device 2" to allow a transition from the open position of the interruption device 2" to the closed position of the interruption device 2" and / or to allow a transition from the closed position of the interruption device 2" to the open position of the interruption device 2".

[0013] Said electrical apparatus 1' may comprise a first housing 15 with which the first socket 13 and / or the control member 2' are mounted.

[0014] Said receiving module 8 may comprise a support frame 8' comprising a central opening 17 forming at least in part said first and second receiving zones 9, 9' receiving the first housing 15 and being capable of receiving a second housing 16 of the additional functional module 5, the first housing 15 being able to comprise removable fixing means 18, 19 cooperating with the support frame 8'.

[0015] Said additional functional module 5 comprises means for performing at least one function requiring an electrical power supply and may be able to be received in the second receiving zone 9' of the electrical apparatus 1', the additional functional module 5 being able to comprise at least a fourth connection pole 6 and a fifth connection pole 7 able to be electrically connected respectively to the second connection pole 4 and to the sixth connection pole 26 of the primary functional module 2 of the electrical apparatus 1' to supply the additional functional module 5, additional functional module 5 in which either the additional functional module 5 comprises a first blocking element being able to block the interruption device 2" in the closed position when the additional functional module 5 is received in the second receiving zone 9' of the electrical apparatus 1',either the additional functional module 5 is capable of acting on the first blocking element of the electrical apparatus 1' blocking the interruption device 2" in the closed position when the additional functional module 5 is received in the second reception zone 9' of the electrical apparatus 1' (, figures 2A à 2E And 3B ).

[0016] The first blocking element can therefore either be present on the apparatus 1' or on the additional functional module 5. In both cases, the first blocking element is arranged to be able to block the interruption device 2" in the closed position when the additional functional module 5 is received in the second reception zone 9'.

[0017] Said electrical assembly 1 comprises an electrical apparatus 1 according to the invention and an additional functional module 5 comprising means for performing at least one function requiring an electrical power supply according to the invention, said additional functional module 5 being received in the second reception zone 9' of the electrical apparatus 1', the fourth connection pole 6 and the fifth connection pole 7 of the additional functional module being electrically connected respectively to the second connection pole 4 and to the sixth connection pole 26 of the primary functional module 2 of the electrical apparatus 1' to power the additional functional module 5, the first blocking element blocking the interruption device 2" in the closed position.

[0018] Said at least one function of the additional functional module 5 may be a function requiring an electrical power supply, excluding an indicator light lighting function linked to the opening position and / or the closing position of the control member 2' of the primary functional module 2.

[0019] Excluded indicator light lighting function means an indicator light lighting function which is generally implemented by means of an indicator light capable and intended to be lit when the interrupting device 2" is in the open position and to be extinguished when the interrupting device 2" is in the closed position. For example, when the primary functional module 2 controls a load 20, such as lighting, the indicator light is lit when the lighting is not powered and is therefore extinguished and the indicator light is extinguished when the lighting is powered and is therefore extinguished. This type of indicator light is most often used to locate and identify the electrical equipment 1' in the darkness of a part of a building (not shown), such as a stairwell (not shown).

[0020] Advantageously, the electrical assembly 1 makes it possible to perform at least one function using the additional functional module 5. Thus, the additional functional module 5 allows customization of the electrical apparatus 1'. In addition, since the additional functional module 5 is optional, it can be installed, removed and replaced by an electrical connection between the second connection pole 4 and the sixth connection pole 26 at any time without impacting the electrical installation. For this purpose, the additional functional module 5 can be replaced by an electrical connection module (not shown) which, when received in the second reception area 9', electrically connects the second connection pole 4 to the sixth connection pole 26. Thus, the electrical apparatus 1' can perform the interruption function, when such a connection module is received in the second reception area 9'.The electrical apparatus 1' obtained is thus particularly modular and can be easily transformed into an electrical assembly 1 capable of performing more sophisticated functions thanks to the additional functional module 5 and can perform the interruption function when a link module is received in the second reception zone 9'. Furthermore, the additional function of the additional functional module 5 is not intended to inform the user about the location or the state of the interruption function, but advantageously extends to functions independent of the interruption function.

[0021] According to one possibility, the primary functional module 2 may further comprise a shunt 28 electrically connecting the second connection pole 4 to the sixth connection pole 26 when the second receiving zone 9' is devoid of an additional functional module 5 and / or an electrical connection module. Thus, the electrical apparatus 1' can perform the interruption function, when the second receiving zone 9' is devoid of an additional functional module 5 and / or an electrical connection module. The primary functional module 2 may further comprise a spring 30 connected to the shunt 28 so as to hold the shunt 28 against the second connection pole 4 and the sixth connection pole 26 to electrically connect them when the second receiving zone 9' is devoid of an additional functional module 5 and / or an electrical connection module.The additional functional module 5 and / or the electrical connection module may be arranged to move the shunt 28 away from the second connection pole 4 and the sixth connection pole 26 against the force of the spring 30 when the additional functional module 5 and / or the electrical connection module is / are received in the second receiving zone 9' (see . figure 5 ).

[0022] According to one possibility, the electrical apparatus 1' may further comprise a control member 2' capable of acting on the interruption device 2" to allow a transition from the open position of the interruption device 2" to the closed position of the interruption device 2" and / or to allow a transition from the closed position of the interruption device 2" to the open position of the interruption device 2".

[0023] The electrical apparatus 1' and / or the electrical assembly 1 is / are preferably intended to be mounted with or embedded in a support (not shown), such as a wall.

[0024] The 2" current interrupting device of the primary functional module 2 can be a monostable switch or a bistable switch.

[0025] In the case of a monostable switch, in the open position of the control member 2', the control member 2' may be arranged so as not to act on the interrupting device 2", which also remains in the open position, and in the closed position of the control member 2', the control member 2' may be arranged to move the interrupting device 2" to the closed position. According to this configuration, the monostable switch module is also called "normally open". According to an alternative monostable switch module, in the open position of the control member 2', the control member 2' may be arranged to move the interrupting device 2" to the closed position and in the closed position of the control member 2', the control member 2' does not act on the closing of the interrupting device 2". According to this configuration, the monostable switch module is also called "normally closed".The control member 2' of a monostable switch module may preferably be a push button (not shown).

[0026] For a bistable switch module, in the open position of the control member 2', the control member 2' can be arranged to move the interrupting device 2" to the open position and in the closed position of the control member 2', the control member 2' can be arranged to move the interrupting device 2" to the closed position. In this case, the control member 2' can preferably be a rocker button capable of adopting two positions. This example is however not limiting.

[0027] The additional functional module 5 may further comprise a second blocking element capable of blocking the control member 2' in the closed position when the additional functional module 5 is received in the second receiving zone 9' of the electrical apparatus 1'.

[0028] The primary functional module 2 may comprise a first connection pole 3 capable and intended to be connected to a first line L of the electrical network and a second connection pole 4 capable and intended to be connected to a second line L1 of an electrical circuit of the electrical installation.

[0029] The first line L may be a supply line connected to the electrical network preferably via a cut-off device, such as a circuit breaker.

[0030] The second line L1 can be a return of the electrical circuit to supply a load 20 of the electrical installation, such as lighting.

[0031] The first line L and the second line L1 can be represented by one or more cables (not shown).

[0032] The electrical installation can preferably be a domestic electrical installation.

[0033] According to one possibility, said at least one function of the additional functional module 5 is a function for shaping the physical parameters of an electrical signal coming from the first line L of the electrical network.

[0034] The additional functional module 5 may comprise at least electrical signal processing means capable of and intended to perform said function of shaping the physical parameters of the electrical signal.

[0035] The processing means may be capable and intended to modify the shape of the electrical signal, to vary the voltage of the electrical signal and / or the intensity of the current of the electrical signal, to vary the power of the electrical signal, to vary the frequency of the electrical signal.

[0036] The processing means may be capable and intended to be operated locally or remotely by control means.

[0037] The processing means can be chosen from: a variator, a relay, a filter, a switch, a semiconductor transistor, preferably of the MOSFET type.

[0038] The control means may, in this case, consist of a control unit, such as a smartphone or remote control, remote from the electrical apparatus 1 and not forming part of the electrical installation. For example, a wireless connection, via means for transmitting and / or receiving electromagnetic waves described below, may allow communication to be established between the control unit and the processing means. According to an alternative variant, the processing means may be actuated via a control button, remote from the electrical apparatus 1, and forming part of the electrical installation. In this case, the connection between the control button and the processing means may be wired or wireless.

[0039] Said at least one function of the additional functional module 5 can be chosen alone or in combination from a function of measuring at least one physical parameter and / or a function of emitting and / or receiving electromagnetic radiation, and / or a display function, and / or an actuation function, and / or a data processing function, and / or a function of transforming a physical signal into an electrical signal or vice versa.

[0040] Said at least one physical parameter can be temperature, pressure, humidity, light intensity, of course these examples are not limiting.

This configuration is particularly preferred to enable the communication of data from the electrical assembly 1 to a control unit (not shown) described below.

[0042] The function of the additional functional module 5 may be capable and intended to be powered and activated when the interruption device 2" of the primary functional module 2 is in the closed position.

[0043] Advantageously, the additional functional module 5 being connected in series with respect to the electrical circuit between the first connection pole 3 and the second connection pole 4 of the primary functional module 2, the means for performing the function of the additional functional module 5 are capable of being powered by the electrical network when the interruption device 2" of the primary functional module 2 is in the closed position. As a result, when the interruption device 2" is in the closed position, the function of the additional functional module 5 can be activated. When the interruption device 2" is in the open position, the means for performing the function of the additional functional module 5 are not powered.

[0044] The additional functional module 5 may comprise an element for storing and / or producing electrical energy and the function of the additional functional module 5 may be capable and intended to be powered by said element for storing and / or producing electrical energy.

[0045] Advantageously, the function of the additional functional module 5 is capable of being powered by an electrical energy storage and / or production element which can be made independent and autonomous relative to the electrical network. As a result, the function of the additional functional module 5 can be activated independently of the open or closed position of the primary functional module 2. For example, when the control member 2' is in the closed position, the function of the additional functional module 5 is no longer short-circuited and can therefore be powered by the electrical energy storage and / or production element and be activated.

[0046] The element for storing and / or producing electrical energy may be a battery, a capacitor, a piezoelectric generator, a photovoltaic generator, a thermoelectric generator, for example of the Peltier or Seebeck type.

[0047] The additional functional module 5 may comprise at least one measuring sensor capable of and intended to perform said measuring function of at least one physical parameter.

[0048] The measuring sensor can be a temperature sensor, a pressure sensor, a hygrometer, a photodetector, an infrared sensor, a transducer, of course these examples are not limiting.

[0049] The additional functional module 5 may comprise at least means for transmitting and / or receiving electromagnetic waves capable of and intended to perform said function of transmitting and / or receiving electromagnetic radiation.

[0050] These means of transmitting and / or receiving electromagnetic waves may be a radiofrequency communication element, for example, Wi-Fi or Bluetooth, a repeater. Of course, these examples are not limiting.

[0051] Advantageously, these means for transmitting and / or receiving electromagnetic waves allow the reception and / or transmission of data which may in particular relate to the additional functional module 5. Such means for transmitting and / or receiving electromagnetic waves may also establish a wireless communication link with a control unit, such as a computer, a smartphone or a digital tablet or to another additional functional module 5 according to the invention and which would also be provided with means for transmitting and / or receiving electromagnetic waves. It is thus possible to interact remotely with the electrical assembly 1.

[0052] The additional functional module 5 may comprise at least display means capable of and intended to perform said display function.

[0053] Advantageously, these display means make it possible to form a visual interface with a user.

[0054] These display means can be a screen.

[0055] The additional functional module 5 may comprise at least actuation means capable of and intended to perform said actuation function.

[0056] The actuating means may be an actuator, for example, a relay, a solenoid, a micromotor, a piezoelectric mechanism or, in general, any type of means configured to transform an electrical quantity into a mechanical quantity or vice versa.

[0057] The additional functional module 5 may comprise at least data processing means capable of and intended to carry out said data processing function.

[0058] The data processing means may be a microcontroller. These data processing means may, for example, be used to process data from the measuring sensor.
