Abstract
A potentiometer, used in particular as a position sensor or position transducer is disclosed, which has at least one wiper path and one wiper that has at least one contact element (), resting with a contact face () on the wiper path and electrically contacting the wiper path; the wiper and the wiper path are movable toward one another. To reduce costs by reducing the amount of noble metal used for the contacting in the potentiometer, the contact element () has an electrically conductive core () and a noble metal jacket (), surrounding the core (), whose annular end face at least partly forms the contact face () (FIG.).
