Abstract: A variable resistance device including a non-conducting base, a resistance supported by the base and forming a track surface, and an electrical terminal connected to the resistance. Also included in the device is a wiper assembly mounted for movement relative to the resistance and comprising a carrier, an elongated conductive spring member having one end secured to the carrier, a conductive coupling element bonded to an opposite end of the spring member and a corrosion resistant contact bonded to the coupling element and disposed to traverse the track surface during movement of the wiper assembly relative thereto.

Abstract: The invention is an electrical component with a body element comprising an organic substrate portion and a laser formed, resistor portion carburized thereon. A first electrical conductor is electrically connected to one location on the resistor portion so as to form one terminal for connection to an electrical circuit and a second electrical conductor is electrically connected to the resistor portion at a different location so as to form another terminal for connection to the electrical circuit.
