Zusammenfassung:A control panel is disclosed. The control panel includes an electrically conductive substrate having a front surface. A first dielectric layer is disposed on the front surface of the substrate. A first electrode layer is disposed on a front surface of the first dielectric layer, wherein the first dielectric layer electrically isolates the first electrode layer from the substrate. The first electrode layer is in electrical communication with a switch circuit adapted to detect a change in a capacitance of the first electrode layer. A substantially transparent film can be provided to cover the electrode. The front surface of the substrate is a decorative surface substantially visible through the first dielectric layer, the first electrode layer, and the film.
