An electrical recessed switch, which essentially consists of an insulating concave piece, recessed in the wall, which can be fastened by means of two screws, which surrounds the fundamental part of the switch, formed by another concave plate, on which are placed the bolts to the network and mobile interrupter contactors, represented by two crossbows of unequal length, curved and elastic, crossed at the height of their free ends, where the corresponding blocks and contact plates are located; This piece is centered inside the switch cover and is fastened to it by means of two screws; such a part also has a central hole in which the control handle is threaded and articulated, supported by a shaft against two molded bearings on the inner and concave side of the cover; this hand, by a lower eccentric stop, conditions the contact or contact separation positions acting on the longest crossbow; which, when released from the pressure of that eccentric, makes contact with the smaller crossbow, by its own reaction, which will be sufficient to press and bend the smaller crossbow, crossed over it; the fastening of the assembly formed by the cover and the piece that carries the contacts with the concave piece that is embedded in the wall, is carried out by two simple screws arranged on each side of the control hand; the rectangular flat edge of the switch cover, carries in each of its four vertices, a small conical tip, susceptible to sink in the soft wall covering.
