Abstract
A switch having a housing and within the housing a control plunger formed with a transverse opening through which a contact arm passes transversely to the direction of movement of the plunger; a tension spring urges the contact bridge against the plunger and the free ends of the bridge cooperate with stationary contacts mounted in the housing; another compression spring urges the plunger into its starting position; the free arms of the contact bridge support, respectively, detaching blocks having arresting edges engageable with the plunger in the event when, during the movement of the plunger, the contact arm accidentally sticks to the stationary contacts; the detaching blocks are provided with abutment surfaces cooperating with guiding edges on the inner wall of the housing to disengage the projection from the plunger.
