Operating unit for electrical device, especially domestic appliance, e.g. hob, has operating element rotatable to set operating parameter, e.g. heating level, with parts movable coaxially relative to each other

摘要

The unit has at least one operating element (10) for reversible mounting on a control panel with at least one signal generator (22) for contactlessly transferring rotational and/or translational movements to a sensor region in the control panel and that can be rotated to set an operating parameter, e.g. a heating level. The operating element has at least two parts that can move coaxially relative to each other.
