Abstract
This invention relates to a position indicator wherein the information on the location of a position-sensing target is obtained by measuring and comparing the ohmic resistances of two electric circuits including an arrangement comprising a pair of parallel conducting wires of high ohmic resistance and a sliding contact conductor slidable along the two parallel conducting wires while maintaining an electrically conductive contact to both conducting wires. The relative position of the position-sensing target kinematically linked to the sliding contact conductor intermediate two extremities of the pair of parallel conducting wires is obtained by measuring and comparing the ohmic resistance of the two circuits respectively including the sliding contact conductor and each of two halves of the two parallel conducting wires divided by the sliding contact conductor. The relative position obtained in the afore-mentioned method is independent of the ohmic resistance associated with the sliding contact between the conducting wires and the sliding contact conductor.
