ABSTRACT:
A self-adjusting plunger switch having a housing (3) carrying contacts (7, 19) with an actuation element (5, 27) for actuation of the contacts (7, 19). A resilient element (11) biases the actuating element outwardly of the housing toward an inoperative position. The actuating element comprises a housing-guided slider (5) and a plunger (27) adjustably connected with the slider. The plunger (27) has a first stop arrest (45) which can be brought from an adjustment between the plunger (27) and the slider (5) through rotational movement around the longitudinal axis of the plunger to engage with a second stop arrest (29a) of the slider as a result of which an arrest of the position between the plunger (27) and slider (5) is attainable.
