Electrical switch i.e. drop arm switch, for use in motor car, has piezo fibers integrated in detent profile curve, and detent element including tip sliding on profile curve and subjecting piezo fibers with pressure at detent positions

摘要

The switch has a pivotable detent pin (1) including a spring loaded detent element (2) positionable at a detent profile curve (3) of a detent curve body (6) at multiple detent positions (a-e). Piezo fibers (4, 4a-4e) are integrated in the detent profile curve. The detent element includes a tip (5) sliding on the detent profile curve. The tip subjects piezo fibers with pressure at the detent positions. Intersection points of the piezo fibers are provided at or in the detent curve body at the detent positions.
