Abstract

A control element includes a carrier element, a luminous foil in which or on which at least two optoelectronic components for generating light along a first main radiation direction as well as contact lines connected thereto are arranged, a diffuser layer downstream of the at least two optoelectronic components with respect to the first main radiation direction, a structured symbol element which is not in front of the diffuser layer with respect to the first main radiation direction and designed to form at least one symbol when the at least two optoelectronic components are operated and in a top view of the diffuser layer when viewed along the first main radiation direction, and a tactile sensor adapted to detect contact or pressure exerted along or opposite to the first main radiation direction to generate an electrical signal.
