Abstract

The present invention relates to a control device having at least one front panel, at least one button panel arranged behind the front panel, and at least one switch responsive to a user's touch of a switchable area on a front side of the front panel in front of said switch. The switch includes at least one light source element arranged at a rear side of the button panel illuminating the rear side of the front panel, and at least one reflector element arranged behind the button panel and the light source element to reflect the light to the rear side of the button panel. The button panel includes at least one cut out that corresponds with the switchable area of the switch or more switchable areas of neighbored switches, so that the light can pass through the cut-out and the front panel to be out of the control device.
