An operating device (1) having an illuminated level control actuating element, in particular for audio systems, comprising a level control (10) which has an actuating element (40) movable along an adjustment path (20). In the interior, the actuating element (40) comprises a light guiding section (160) by which light coupled into a coupling section (130) on the lower side face of the actuating element (40) is guided to one or more exit zones (170) of the gripping faces (60) of the actuating element (40), and a plurality of illumination means (100) which are controllable for individual positioning are arranged along the adjustment path (20), such that in any position of the level control (10) along the adjustment path (20) the actuating element (40) covers at least one of the illumination means (100) with the lower side face of the actuating element.
An operating device with a level control, that comprises an actuating element having an interior, the actuating element being movable along an adjustment path, wherein the actuating element comprises a bottom face and outer gripping faces, characterized in that the actuating element comprises in the interior a light guiding section which, in a coupling section at the bottom face surface of the actuating element, conducts injected light to one or more exit zones of the gripping faces of the actuating element and along the adjustment path a plurality of separately controllable illumination means is arranged so that the actuating element covers in each position of the level control along the adjustment path at least one of the illumination means with its bottom face surface, and the illumination means and the level control are connected to a control device which activates based on the position of the level control only the illumination means for light emission, which are covered by the coupling section of the actuating element;
