Abstract

A control element for a motor vehicle is disclosed that includes at least one rotary actuator and one actuating element integrated in the rotary actuator, whereby the actuating element can be moved relative to the rotary actuator, and whereby a connecting member, which interacts with an optical system, is molded to the actuating element. A connecting member extends into the optical system such that the deflection of the actuating element can be evaluated as a signal by the optical system. The optical system includes at least one light-emitting and at least one light-absorbing light guide element, whereby one light guide element is arranged on one side of the connecting member and one light guide element is arranged outside the connecting member so that a deflection of the actuating element is analogous to the absorption of light.
