ABSTRACT:
A wiper for an electric rotary potentiometer, in particular for use as a rotary position transducer, having a contact spring for pickup on a resistor track, and a rotatable spring holder on which the contact spring is secured nonrotatably. To save time and expense in assembling the contact spring and the spring holder, at least one fastening tang with a detent head protrudes at approximately right angles from the spring holder, and the contact spring has circular-annular-segmental detent straps, disposed on a circle, which lock into place behind the detent head under spring tension.
