摘要

Pushbutton device for the control of electrical circuits, characterized in that it comprises a metallic reinforcement (1) formed by a structure in the form of a fixed box in which a plurality of deliverable organs (12) integral with the pushbuttons are housed ( 14), counteracted by springs (16) and cooperating with a slidable longitudinal horn (23), loaded by a spring and suitable for unitarily retaining the buttons that are lowered, or to allow release when it is lowered, even partially, another of the push buttons, a plurality of electrical switches (43) being connected to the aforementioned armature in a number equal to that of the push buttons, each switch being provided with fixed electrical contacts cooperating with tilting contacts (50, 50a) operated by a sliding plate (57), provided with reentrant struts (61) and pawned by one of the sliding transverse organs (12) integral with the push buttons, by or that the descent of a button determines the desired switching in the electrical circuit that is directed to the relative switch.
