Abstract
An electric switch of the normally open type includes a body, an actuator moveable between a high rest position and a low active contact position, and first second elastically deformable contact blades supported by the body. A first contact section of the first contact blade extends above a second contact section of the second contact blade. The contact sections are superposed and distanced from each other when the actuator is in high rest position, and they are in mutual electrical contact when the actuator is in low position to establish an electrical switching path. The first contact section includes a longitudinal rib that protrude downwards with respect to the plane of the underside of the first section and which is able to cooperate with the transversal contact edge of the central opening. The transversal contact edge comprises a transverse contact bend for cooperating with convexity of the longitudinal rib.
