Abstract

A proximity sensor for controlling a component that may be installed on a window, on an interior or exterior pillar of a vehicle, on a control panel or any suitable location on a vehicle or any other structure. The sensor includes a substrate and a conductive layer disposed on the substrate. The conductive layer is formed from a conductive ink composition with the conductive layer defining at least one circuit for controlling the component when a user is in proximity to the conductive layer. A protective layer is disposed over the conductive layer. At least one of the conductive layer and the protective layer defines a graphic formed through the layer for visual identification to the user.
