- the invention proposes then to cut a window in the side wall of this base, so that the electronic part can have more space.
- this large electronic component can project into the thickness of the side wall of the base at the window.
- the first advantage is that the solder tabs protruding from the back of the printed circuit board can be housed in the base and it is therefore not necessary to cut them off the raz ⁇ what would be expensive and present the risk of causing a disconnection of these legs).
- the second advantage is that it is possible to place electronic components on the back of the printed circuit.
- the third advantage is that it is possible to use a larger printed circuit, which can carry more electronic components.
- the base of a mechanism generally has chamfered edges, so that shift the printed circuit relative to these edges allows to have the entire width of the base.
- the "protruding portion” comprises a housing that completely closes the window of the base.
- the housing encloses an electrical relay or any other large electrical or electronic component (a capacitor for example).

- the cover 175 has in particular, on its rear free end edge, two notches adapted to fit the shape of the screw holes 143A.
- the screw holes 143A are wedged between the cover 175 and the base 110 (see Figure 3).
- the insulating shell 141 of the connection terminal block 140 is blocked in rotation by the cover 175 and the base 110 when a user maneuvers the screws 143 (we speak of "angular blocking" of the terminal block around an axis parallel to the axis of the screws).
- the front wall 171 of the closure cap 170 here has a front opening 177 for the passage of the indicator 190 and the light from the light-emitting diode 134.
- This front opening 177 here has a substantially rectangular shape, and extends in the center of the front wall 171,
- the indicator light 190 has a parallelepiped-shaped body 191 of equal height and width, with the mounting clearance, at the height and width of the front opening 177.
- This body 191 carries at the rear means of securing closure cap 170.
- These securing means are formed here by, on one side of body 191, a rigid tongue 192, and, on the other, a detent tongue 193 adapted to hook onto the rear of the front wall 171 of the closure cap 170.
- the indicator 190 is formed of a single piece in a material transparent or translucent, so as to pass light emitted by the light emitting diode 134,

- the front wall 171 of the closure cap 170 here has a circular opening 178 of small size, allowing only the passage of a needle.
- This circular opening 178 is here located at the right of a switch button 138 which is carried by the printed circuit 132A of the electronic control board 132 and which makes it possible to reset the settings of the control mechanism 100.
- the equipment support 500 has a frame shape which delimits a reception opening 501 for mechanisms 100, 200.
- securing a trim plate to report aesthetically on the electrical equipment 10.
- These securing means are here in the form of four circular orifices 503 at the corners of the frame.
- locking means of the mechanisms 100, 200 It also comprises locking means of the mechanisms 100, 200.
- These locking means are here in the form of attachment ribs 504 which extend along two opposite edges of the receiving opening 501 and which allow to engage the mechanisms 100, 200.
- the base 110, 210 of each of these two mechanisms 100, 200 comprises for this purpose snap tabs 118, 218 which are cut into the end faces of their side walls 111 and which are provided for hooking to these fastening ribs 504.
- the outlet mechanism 200 will not be described here in detail as it is of the type already marketed for example under the reference LEGRAND 077501 (standard Euro-US) or under the reference LEGRAND 077511 (Italian standard). More generally, it may also be any other type of socket that can be integrated into the equipment support 500. It will be observed only that it has a connection terminal block (not visible) for connecting the neutral wire and the ground wire of the local electrical network, as well as the free end of the cut phase wire 150 of the control mechanism 100.
- This cut phase wire 150 then has a length such that when the two mechanisms are attached in a similar manner in the equipment support 500, it can be connected to the connection terminal block of the socket mechanism 200. In this way, the Control mechanism 100 can supply power to the socket mechanism 200 or suspend this power supply, depending on the signal received by relay 130 (taking into account the signal received by antenna 139).
- the two mechanisms 100, 200 are described as modular in that their bases 110, 210 have substantially parallelepiped shapes twice as high as wide. Thus, once attached in a similar manner in the equipment support 500, the two mechanisms 100, 200 occupy the place of a standard cubic mechanism. It is therefore understood that these two mechanisms 100, 200 could be reported in a standard square-shaped apparatus holder, whose square opening would have a width of about 45 millimeters.
- the socket mechanism (200) could have a substantially cubic shape, 45 millimeters wide and high (the depth of the mechanism may be less than or equal to 45 millimeters).
- the control mechanism (100) will remain on the other hand of identical shape to that shown in the figs.
- the two mechanisms can be installed in any type of equipment support, for example in an equipment support that can receive two cubic mechanisms of 45 millimeters wide and high (the remaining space can be left free or can be occupied either by another modular mechanism, or by a cache). Both mechanisms can also be installed in other types of media, larger or smaller that this one.
- the two hubcaps 300, 400 each have the form of a flat plate which is bordered at the rear by a rim and which is pierced at its center by an access opening (to access 190 indicator or the cells of the socket).
- These hubcaps 300, 400 comprise latching means (not visible) provided to attach to the equipment support 500 (alternatively, the hubcaps 300, 400 could be attached to the bases 110, 210 of the mechanism 100, 200).
- each of the two mechanisms could have a different function.
- the socket mechanism could be replaced by a mechanism having a network or jacking function
- control mechanism may be designed not to provide a switching function when it receives the order from a user, but rather to provide a different function such as for example that of a circuit breaker (when the current exceeds a threshold), or that of a light that emits light whose properties vary according to the current flowing through it.
