Abstract

Improved stop switch for automobiles, of which they are constituted by a body that occludes an axially disposed piston, and on which a coil spring acts, depending on the rise or fall of the aforementioned piston, the unison movement of a metal bridge intended to slide either on two of the opposite walls of the switch, or on the protruding parts made in a pair of terminals also located in the mentioned walls, the present switch being characterized as being constituted by a pair of hollow bodies, one of them inside the other and immobilized both to each other, immobilizing also between the edge of the partially internal body and the internal face of the base of the outer body, an elastic membrane of rubber, by means of which a sealed chamber is formed, inside which the coil spring is arranged., whose upper end is fixed in a central lug that offers the base of the partial body interior, while its other end rests on the horizontal section that offers a metal bridge, which is immobilized by a central lug that has the aforementioned elastic membrane, while, below, said membrane has a central hollow in which it is located the end of a piston in charge of sliding axially, with limited travel, by a tubular extension that provides the base of the outer body.
