The rotary light switch has an actuator that can be rotated around an axis and that can be moved in the axial direction, and that is non-rotatably coupled to a rotational position indicator and axially coupled to an axial position indicator. Moreover, it has an electronic evaluation circuit to which the signals from the rotational position indicator and from the axial position indicator are fed and, according to a permanently stored decision matrix, said evaluation circuit uses the signals to derive discrete switching states that are converted into switching signals that serve to actuate the lighting system of the vehicle. The rotational position indicator comprises a potentiometer that generates a negligible resistance to the rotational movement, so that no mechanical influences are caused by the rotational position indicator.

Abstract: A rotary switch for installation in the dashboard of a vehicle has a switch housing, an actuation shaft that is arranged rotatably in the switch housing, a knob that is mounted on one end of the actuation shaft, and a ring-shaped faceplate that surrounds the knob and that is detachably fastened to the switch housing. The faceplate is connected to the switch housing by a locking mechanism. This locking mechanism can be released by a relative rotation between the faceplate and the switch housing. The knob can be moved axially in a predetermined rotational position and is coupled non-rotatably to the faceplate by means of this axial movement. In order to detach the faceplate from the switch housing, the knob is moved into the predetermined rotational position and then moved axially and turned at the same time, whereby the faceplate also turns and the latched connection between the faceplate and the switch housing is released.
