Key-switching device having a transparent covering film

摘要

A key-switching device has a covering film over an electrical switching path 5, 8, which covering film has at least one transparent edge zone 13. In order in a simple manner to achieve illumination of the transparent edge zone 13, a layer 3 consisting of luminous material is provided under the covering film 9 as an illumination device, which layer 3 is either arranged directly on the underneath of the covering film in the region of the edge zone 9 or is placed under the switching films 4, 6 which form the switching path. <IMAGE>
