Abstract:
1. A control element for a motor vehicle comprising: at least one rotary actuator; at least one actuating element integrated in the rotary actuator, the actuating element being movable relative to the rotary actuator; an optical system; and a connecting member, which interacts with the optical system, is molded to the actuating element, the connecting member extending into the optical system such that a deflection of the actuating element is evaluated as a signal by the optical system, wherein the optical system further comprises at least one light-emitting and at least one light-absorbing light guide element, and wherein the light-absorbing guide element is arranged on a side of the connecting member and the light-emitting guide element is arranged beyond a periphery of the connecting member so that a deflection of the actuating element is analogous to the absorption of light.
