<p>The inventive pushbutton has a plunger (3) which can be displaced longitudinally between two switching positions along the axis of motion (X1). A contact washer (6) is clamped between two springs (4, 5) on said plunger. Three connecting contacts (A1, A2, A3), each with two contact surfaces (11, 12) which are set apart in the direction of the axis of motion (X1), are situated in the switch housing (1) of the pushbutton. Said contact surfaces form a make contact, a break contact and a root contact and are electrically contacted in the two switching positions by the contact washer (6) accordingly.</p> |
