The invention relates to an operating element, in particular in motor vehicles, to the surface of which pressure-sensitive piezo-resistive sensors for switching and controlling vehicle-internal processes and applications are applied, the operating element being characterized in that a plurality of the piezo-resistive sensors (8) is arranged tightly next to and below each other in rows and columns in a matrix on a substrate layer (11) which covers the entire operating element (1), and the individual sensors (8) are connected, via conductor paths (12), to an evaluation unit (9) that processes the individual sensor signals.
