Sensor element device for an operating device, operating device and electrical appliance having such an operating device

A sensor element device for an operating device having a luminous display, wherein said sensor element device comprises a sensor element for a capacitive touch switch of said operating device, said sensor element device comprising:

• a light guide for said luminous display, said light guide consisting of light-transmissive material, said light guide comprising an input region for light and an emission region for light,
• shielding material which encloses said light guide except for said input region and said emission region, said shielding material being light-nontransmissive in combination with said light guide,
• at least one metallic sensor element, said metallic sensor element consisting of at least one metal part,
• wherein:
• said sensor element device comprises a lower side and an upper side,
• said sensor element extends from said lower side of said sensor element device to said upper side of said sensor element device,
• said sensor element device forms an integrated module with said light guide, said shielding material and said sensor element,
• said sensor element projects as far as a plane of said lower side of said sensor element device and at least partially defines said plane of said lower side,
• no part of said sensor element device protrudes downward beyond said lower side of said sensor element device or beyond said sensor element.
