Abstract

An electrical switch (1) is proposed on the actuator (4) of which, which can be moved in a housing (2), there are arranged contact bridges (8) which can be brought into contact with break contact surfaces (11) which are located, in turn, in a base (5) secured to the housing (2). Two guide curves (14, 15), which have different configurations and in which a pin (19, 20) respectively engages, are located on two mutually opposite surfaces of the actuator (4) which extend parallel to the direction of actuation. The two pins (19, 20) serving the purpose of the notching are coupled to one another by means of a connecting element (21) which is elastically deformed in sections during the movement by the different guidance of the two pins (19, 20).
