Abstract:
1. An operating element comprising: an actuator rotatably mounted on a displaceable bearing block by a bearing shaft such that the actuator can be rotationally actuated about a rotation axis and pressure actuated along a displacement axis normal to the rotation axis; a detent wheel connected to the bearing shaft to rotate along the rotation axis during a rotational actuation of the actuator and to displace along the displacement axis during a pressure actuation of the actuator, the detent wheel having a detent contour; and a spring-loaded detent element having a lever with a detent pin, the lever being pivotable at one end about a rotational bearing on the bearing block, the detent pin being biased, by a spring, along the displacement axis against the detent contour of the detent wheel; wherein the actuator including the bearing shaft with the detent wheel displace along the displacement axis during a pressure actuation of the actuator such that the lever displaces along the displacement axis to a fixed position in which the detent pin is pressed along the displacement axis against the detent contour of the detent wheel with sufficient force to block rotational mobility of the detent wheel thereby blocking a rotational actuation of the actuator during the pressure actuation of the actuator.
