ABSTRACT:
In an embodiment of the invention it is possible to create an operating unit (11) with a rotary toggle (14), which has an integrated bearing device (15) with which the operating unit (11) can be magnetically fixed to a cover (12). The operating unit (11) has a control means (23) with a microprocessor for evaluating magnetic signalling means (19), which detect a rotation of the rotary toggle (14) relative to the bearing device (15). Through a first transformer (26) in the operating unit (11) and a second transformer (29) on the underside of the cover (12), it is possible to have both a signal transmission and a power transmission between the operating unit (11) and the electrical appliance.
