ABSTRACT:
A variable resistance control employing a support plate and a resistance element having a pair of spaced resistance paths applied on a base and rotatably mounted on the support plate. A pair of terminals with integral contacts are secured to the support plate and are disposed intermediate the base and the support plate. The pair of resistive paths are concentrically disposed on a surface of the base and electrically connected to each other. Each of the contacts engages a respective one of the resistive paths. In the assembly of the control, terminals are initially joined by a bridging member and, after the terminals are secured to the support plate, the bridging member is severed from the terminals providing a pair of separate terminals with integral contacts.
