Abstract

An electrical switch mechanism, characterized in that it consists essentially of a contact box, consisting of two U-shaped profiles coupled together to form an easily removable parallelepiped container, one of which u constitutes the mechanism frame, inside which two contacts are mounted insulated electrical carrying over them an elastic bridge of conductive material that is mounted on the lower and inner end of a vertically displaceable piece, like a piston, passing through said u, so that said plunger is subjected to the action of a concentric coil spring that surrounds it and that is supported, by its lower end, on the upper side of the u, while its upper end is in contact with an upper cap secured to the external end of the plunger and the quoted spring is wrapped in turn by a tubular protection whose walls act as guides of the internal walls of the mentioned cap in its vertical movement, all this so that, when descending the piston overcoming the resistance opposed by the spring, the bridge closes the circuit through the two contacts against which it comes to rest and finally the second u, as a side cover and whose spacing between its arms corresponds substantially to the length of the aforementioned frame, is mounted at 90 [deg.] in relation to the first, coming attached to the latter by easily removable joining means, such as screws that are inserted in protrusions, in the manner of ears, integral with the first frame piece.
