Abstract

An operating element, in particular for a motor vehicle component, includes an actuating element that is movably supported in a carrier element and acts, in particular, on a switch element. To detect an approach of a user to the operating element, but at the same time to prevent a misdetection by a movable component, an electrically conductive sensor element of a capacitive proximity sensor and at least one shielding element are arranged in an interior space of the actuating element, the sensor element and the shielding element being connected to a printed circuit board in an electrically conducting fashion.
