Abstract

Security switch, of which comprise two sets of contacts, fixed on a plate anchored to a housing and other mobiles arranged in a skate that guided by the housing slides near the plate that includes the fixed contacts, said skate presenting a appendix that emerges towards the outside of the casing, facilitates the actuation of the commutator, essentially characterized in that the skate has, on the face from which the actuator emerges, several protrusions that intended to rest on the corresponding inner face of the casing, define a area in which the ends of a laminar spring bent at dihedral angle are seated, whose spring at its advantageously rounded apex exerts a constant pressure on the inner surface of the corresponding face of the casing, and further characterized in that the casing, being conventionally endowed of a torn hole through which plays the appendix of actuation of the skate, involves, tra at least one torn orifice, two or more locking zones intended to admit the vertex of the spring that the skid carries, whose zones constituted by embossments or climbing, being located in the path that the spring follows, offer the latter two or more fitting zones, each of which coincides with a working position of the switch, with the particularity that said spring has in its central area a hole that frees the passage of the appendix of the actuator, which when passing through the hole, ensures immobility of the spring in its constant work action.
