Abstract

An operating apparatus for an electrical device has a closed transparent control panel, lighting means underneath the control panel in order to shine through, a plurality of holding magnets underneath the control panel and a movable operating element being held magnetically on the front side of the control panel that can be moved with respect to the lighting means and the holding magnets. A plurality of counter-magnets are provided in the operating element for interacting with the holding magnets in order to guide the operating element as an operating movement and hold it on the control panel, wherein sensor means underneath the control panel detect a rotational position of the operating element. The operating element is transparent in a direction from the lighting means to the operating element, wherein, for this purpose, it has a plurality of transparent regions that are separated from one another without transmission between one another.
