Abstract
A potentiometer including a resistance element positioned within the housing. The resistance element comprising a substrate and a resistive track deposited thereon has a collector element and three terminating pads electrically connected to each end of the resistance track and to the collector element. A slidable wiper is electrically connected to the collector element and contacts the resistance track to vary the resistance of the circuit. Clips are mounted on the resistance element to provide electrical connections between the terminating pads and terminal posts connecting the resistance element to an external circuit. The clips are formed of an S-shaped, resilient, electrically conductive element having lower and intermediate sections to resiliently clamp the resistance track, and an upper section with two bifurcated arms to engage the terminal post. The clips provide an electrical connection, retain the terminal posts in the housing, and bias the substrate against tracks in the housing to secure the substrate, to absorb vibrations and to compensate for dimensional changes resulting from temperature fluctuations.
