ABSTRACT:
An electric potentiometer is proposed which serves to convert a mechanical movement into an electrical value. The potentiometer includes a pickup embodied as a wiper and a resistor pad which has a plurality of connections for parallel resistors distributed over the displacement range of the pickup and serving as support points. With these parallel resistors, the partial resistance established by the pickup can be varied to a predetermined course. The support points extend crosswise to the contact track of the pickup on the resistor pad and are embodied as only so long that they terminate before reaching the contact track.
