ABSTRACT:
A resistance transducer with a non-linear characteristic curve, which transmitter has a resistance track with a variable cross-section on an insulating carrier and a slider engaging on the resistance track. On the resistance track on the insulating carrier of a thick layer system at least one additional layer is applied by the same technology made of a conducting resistor substance, and shaped such that it forms a rib which extends in a direction of movement of the wiper, the rib tapering outwardly perpendicularly thereto, and the wiper transversely engages the rib to form an approximately point-like contact surface.
