Abstract

An automotive glazing having a non-galvanic contact for an electrical device associated with the glazing is disclosed. The glazing comprises a first ply and a second ply of transparent glazing material having a ply of interlayer material extending between the plies of glazing material. The glazing also comprises an electric circuit, having a first connector portion, situated adjacent the ply of interlayer material, the first connector portion being configured to form a coupling region such that electrical signals in the circuit are can be coupled between the coupling region and an electrical device placed on the glazing. A second connector portion is included on the surface of the second ply of glazing material situated away from the interlayer material, and connectable to an electrical device. The second connector portion is adapted to receive a ferromagnetic core. This leads to an increased coupling factor (efficiency), making the connection suitable for powering a variety of electrical devices used within automotive vehicles and conventionally mounted on glazings.
