Abstract (en)
[origin: DE4330576C1] In the case of a momentary-contact switch, a pressure point, a switching movement and a resetting stress are produced during one movement of its switching plunger (6). In order to achieve this with a simple construction, even in the case of short movements, with reliable contact operation after overcoming the pressure point, an integral spring element (16) is provided. The latter has guide limbs (17, 18), which are bent into a hairpin shape, between a contact arm (26) and a resetting arm (21). An inclined step (24) is designed on at least one of the guide limbs (18) in order to produce the pressure point. <IMAGE>
