ABSTRACT:
A transducer in the form of a potentiometer provides an output signal indicative of a position of a component. The potentiometer comprises a body, a member moveable relative to the body and having an end portion for coupling to the component, and a resistor mounted to the body. A wiper is coupled to the member and forms a slidable electrical contact to the resistor. The potentiometer also comprises a contactor means for providing selectable contact positions to the resistor of respective first and second electrical conductors, so as to provide a selected operating section of said resistor.
