Abstract

The invention relates to an electrical device (1), especially a radio device, enabling improved accommodation of the operator elements and the illumination of said operator elements at the same time. The electrical device (1) comprises a display device (5), and at least one operator element (10) located preferably in the direct proximity of said display device (5). Said operator element can be illuminated. The display device (5) lies on a lighting body (15), and is illuminated via this lighting body by means of at least one light source, preferably a light-emitting diode, inside the electrical device (1). The at least one operator element (10) is configured so that it is at least partially transparent, and also lies on the lighting body (15). Said operator element can also be illuminated via the lighting body (15) by means of the light which can be radiated from at least one light source (20).
