Abstract
An operator control device for a functional device of a motor vehicle, includes a rotary actuator which is rotatably mounted on a retaining element and which has at least one coding element. A detection device detects an absolute rotational angle between the rotary actuator and the retaining element on the basis of coding of the at least one coding element. A latching device provides a plurality of latching positions that are predefined for the rotary actuator along a rotational direction. The detection device is designed to detect the respective latching position and the absolute rotational angle between at least two of the latching positions on the basis of the coding of the at least one coding element. A sensor device detects touching of the rotary actuator.
