Abstract

The operating device for an electrical apparatus or a system, in particular for a vehicle component, is provided with at least one elastically mounted operating element (12), a counter-element (14), relative to which the at least one operating element (12) is movable when actuated, thereby varying the distance, namely as seen in the movement direction, and at least one capacitor (38) which comprises a first carrier body (20) with a first capacitor electrode (34) and an elastically bendable second carrier body (22), designed as a bending bar, having a first end (26) and a second end (32) opposite said first end and having a second capacitor electrode (36) opposite the first capacitor electrode (34). Connected to the first and second capacitor electrode (34, 36) is an evaluation unit (42) for determining the capacitance and/or a change in the capacitance of the at least one capacitor (38) upon actuation of the at least one operating element (12).
