1. A control element comprising:
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 arranged downstream of the at least two optoelectronic components with respect to the first main radiation direction;
a structured symbol element which is not arranged in front of the diffuser layer with respect to the first main radiation direction and is 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;
a tactile sensor adapted to detect contact or pressure exerted along or opposite to the first main radiation direction and to generate an electrical signal therefrom; and
at least one of the following layers:
an adhesive layer disposed between a support element and the luminous foil; or
a cover foil layer arranged downstream of the diffuser layer with respect to the first main radiation direction,
wherein a distance between the diffuser layer and the at least two optoelectronic components depend on a distance between the at least two optoelectronic components.
