Operating element for controlling equipment, e.g. controlling vehicle air conditioning, has a rotating lock operating element with a locking pin to engage in a locking section

摘要

A locking pin (13) fits on an active locking end (14), i.e. a locking head. A complementary locking contour (12) is correspondingly molded on a rotating lock operating element (11). Complementarity exists only near the deepest locking stop position in such a way that there is maximum contact between the locking contour and the active locking end. The locking pin stands under spring action with regards to its locking strength. The spring action may be mechanically or electrically adjustable, the electrically generated spring action being programmable.
