Abstract
A potentiometric position transducer comprises a resistive track movably mounted within a housing. A portion of the resistive track is between two fixed electrical contact points. A third electrical contact is moveable over such portion, corresponding to the position or setting of an exterior device, such as the throttle of an internal combustion engine. Drive means are provided to move the resistive track, to repeatedly substitute new portions of the resistive track between the two fixed contact points. Wear is spread over the entire resistive track.
