The multilayered foil covering the whole or parts of operating or designer surfaces is provided on its outer surface with three-dimensional decorative shapes by means of deep-drawing and/or hot-forming processes. The multilayered foil covering the whole or parts of operating or designer surfaces is provided on its outer surface with three-dimensional decorative shapes by means of deep-drawing and/or hot-forming processes. The rear zones of raised sections thus produced house key caps with integral reflectors and light-guide chambers, as well as cutouts for LEDs serving for point or area illumination of keys.
