Abstract: A thick-film potentiometer having a support substrate, particularly a ceramic substrate, onto which there is applied at least one resistance track of resistance composition which is electronically contacted via conductor lines on the support substrate at its ends and under circumstances at contact points therebetween and having a wiper track which extends along the resistance track and over which a wiper is swingable. The wiper track is formed of a plurality of the conductor lines which are narrow compared with the length of the wiper track and are arranged, spaced apart from each other, substantially at right angles to the wiper track, and the resistance track is arranged on the support substrate exclusively outside of the wiper track beyond and adjacent to the conductor lines.

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.
