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.
