Removable electrical-accessory module, an electrical box for receiving such an accessory module, and a replacement method for replacing such an accessory module

Abstract

An electrical-accessory module (130) for engaging in an electrical box (110) includes a casing (131) made of insulating material, and that includes a side wall (132) that is closed at the front by a front wall (134) for defining an inside space for receiving an electrical mechanism (140). The electrical-accessory module includes firstly snap-fastener elements (137) adapted to catch onto the electrical box, which snap-fastener elements include at least one catch member (137A) that is movable between a retracted position in which it does not hinder the insertion of the casing into the electrical box, and an extended position in which it is adapted to catch directly onto the electrical box, and secondly release elements (137C) for releasing the snap-fastener elements, which release elements are accessible via the front, through an access opening (139) provided in the front wall, so as to return the catch member into its retracted position.
