Abstract

Contactor perfected for electronic devices, essentially characterized in that the insulating plate that includes the circuit and the wires welded to it, is adhered to another plate also insulating provided with as many holes as contactors have to be mounted, matching each hole with a set of two wires conductors located next to the edges of the opposite sides of the hole, plus another conductive wire in the center and between the other two, also comprising a bistable metallic disk of flexible and electrically conductive thin plate, curved and shaped with a convex upper face and the lower concave, this bistable metallic disk being housed in the cavity formed by the hole of an insulating plate sealed by the other carrier of the circuit, the concave face of said bistable disk resting on the two threads of the opposite sides of the cavity so that when pressed by the key or pushbutton, it will change its shape to flex and will contact through its lower central area with the central conductor wire closing the circuit, which will reopen instantly when the disc recovers its primitive position when it is no longer pressed by the key or pushbutton, all of whose discs will be covered, as well as the iron the holes in which they are housed, by a thin transparent sheet adhered, which holds and holds them in their housings.
