Abstract (en)

[origin: WO2017071725A1] The invention relates to a capacitive touch switch for an operating device of an electronic household appliance, comprising an at least partially translucent cover plate having a user side facing a user, a carrier plate arranged on a side of the cover plate facing away from the user side and at a distance from same, and a light source (34) mounted on the carrier plate (16). The touch switch also has a sensor plate (20) arranged between the cover plate (10) and the carrier plate (16), and an at least partially translucent substrate (22) and a sensor layer (24a, 24b) made of a electrically conductive material. In addition, the sensor layer (24a, 24b) has a sensor region (28) made of the electrically conductive material for forming a sensor electrode, and a symbol region (32) without the electrically conductive material for forming a symbol that can be backlit by the light source (34).
