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.
