Abstract

A capacitive touch switch having a printed circuit board and capacitive electrode provided on a surface of the printed circuit board is disclosed. The printed circuit board is interposed between a transparent planar light guide and the electrode, the planar light guide being attached to a first face of a transparent cover whose second face is adapted to be touched by the user, a light source being connected to the printed circuit board and being able to convey light to the planar light guide.
