Abstract

An electrical switch includes a base, an actuating rod comprising a lateral wall guided in a bore of the base, a return spring for the rod which moves with respect to the base. The return spring comprises a last elastic turn which, during the actuating travel of the rod, bears against an abutment surface of the base and which cooperates with a ramp formed in the side wall which deforms it radially. The bore has a series of axial ribs projecting into the bore, each of which is slidably received in a complementary axial groove formed in the side wall. A radial upper end facet of each axial rib forms a portion of the abutment surface.
