Abstract
Simplified rotary switch, essentially characterized by being constituted by an insulating base provided with a series of perimetral grooves that are crossed by lamellae constituting the fixed contacts, which are anchored in recesses with respect to the internal periphery of the housing of the commutator, which is fixed to said base through lower temples that are riveted in perimetric notches of the same base mentioned, which has a central hole and a circular series of holes around it, that for the introduction of an outgoing pivot of the carrier block of the movable contacts acting as a turning point thereof, and is for stabilizing the position of said movable contacts with respect to the fixed ones, with the collaboration of a ball detent installed in the lower base of said block.
