Abstract

The present disclosure relates to an operating member including a support; an actuating part, which has an actuating surface facing towards an operator, and the actuating part has an edge region, which is provided outside the actuating surface and via which the actuating part is supported on the support; wherein the actuating part has a layer structure, defining the actuating surface, and the layer structure has at least two layers that differ in the modulus of elasticity; wherein, in a transitional region between the edge region and the actuating surface, a layer with the smallest modulus of elasticity is a highly elastic layer, and has the greatest layer thickness compared to other layers of the layer structure, in order to provide an elastic compliance of the actuating part; a force sensor disposed between the support and the actuating part detects a displacement of the actuating part.
