Pushbutton switch with rotary contact disc - has longitudinal housing grooves cooperating with latching lugs and counter lugs of pushbutton proper

摘要

The contact disc is rotatably mounted in the switch housing and cooperates with a coupling of a twisting element. The latter is insertable in the blind cavity of the push-button. The linear movement of the push-button is ensured by lugs engaging longitudinal grooves in the housing inner walls. In front of the groove (17) are mounted counters tops (20, 27). - The counters tops are mounted in the direction of the free end of the sleeve-shaped housing part. The counters tops cooperate with the stops (16, 19) on the push-button (10), when it is inserted into the housing sleeve (9). One counters top is preferably in the form of an annular groove (20) retaining an annular bead (19) of a flexible ring (18) on the periphery of the push-button
