Abstract:
1. A sensor element device for a capacitive proximity switch of an operating device with an operating panel, said sensor element device having an upper side for contacting an underside of said operating panel, said sensor element device comprising: an illuminated display comprising a sensor element, said illuminated display having a top side facing said underside of said operating panel, said illuminated display comprising a frame body with a lighting direction towards said underside of said operating panel, wherein said illuminated display is electrically conductive at least on said top side facing said underside; and a material layer comprising an elastic, electrically conductive material having a first side and a second side, wherein said illuminated display is attached to said first side of said material layer and said second side of said material layer is attached to a component carrier, wherein said illuminated display has an electrically conductive connection from said upper side to said underside for establishing contact to said material layer, and wherein said illuminated display is further connected via said material layer to an electrical port of a control unit, the sensor element is made up from the topside of the frame body, wherein the frame body is electrically conducting, wherein the sensor element as part of the frame body is in contact with said underside of said operating panel, wherein the frame body is placed upon the first side of said material layer, said material layer comprising the elastic, electrically conductive material, wherein said illuminated display and said frame body are designed in a block-like manner, wherein said frame body and said illuminated display form a function unit, wherein said electrically conductive connection is a conductive lacquer provided on said top side of said illuminated display at least in an area of contact by one part of said sensor element with said underside of said operating panel and extending from a rim of said illuminated display to a lower area or to an underside and to said material layer, wherein said conductive lacquer is translucent, and wherein the frame body and the illuminated display form a structural unit.
