Zusammenfassung:A description is given of a rotary actuator having a stator arranged on a capacitive sensing-based sensing surface of a touch panel, also having a main body rotatably mounted on the stator, and having a ramp ring able to be twisted counter to the stator, on which ramp ring there is arranged at least one electrically conductive sliding contact element which bears on the sensing surface by a sliding contact and the position of which on the sensing surface can be determined by the touch panel, wherein a metal or metallized ring is arranged on the main body so as to be able to be displaced axially counter to a return force, wherein the ring is coupled both electrically and mechanically to the sliding contact element, and wherein a displacement of the ring in the direction towards the touch panel causes the sliding contact to mechanically lift off the sensing surface.
