ABSTRACT:
A pushbutton switch has a plunger guide housing in which a plunger is displaceably guided and on which control elements are detachably mounted on different sides of the plunger axis. Each control element is pushed onto a guide extending parallel to the direction of motion of the plunger and is held by a locking bolt which is rotatably mounted in the plunger guide housing. In each control element housing is mounted a spring-loaded actuator for displacement transverse to the direction of motion of the plunger, so that it can be moved by pressing the plunger from a rest position into a working position. This design has the effect that the forces produced primarily by the return springs of the actuators and transmitted over the actuators in their working position, do not exert a great force on the plunger extending parallel to the direction of motion of the plunger.
