Abstract

A rotary switch configuration for a household appliance includes a rotary knob seated in a cutout in an appliance panel and firmly connected to an actuating shaft so as to rotate with it but move axially, the actuating shaft transmitting the rotary movement of the rotary knob to a switching shaft of a switching unit mounted behind the appliance panel. Exact and wobble-free guidance of the rotary knob is achieved by the actuating shaft being rotatably mounted on the appliance panel by a bearing device.
