Abstract: In connection with a movable tap for potentiometers, adjustable rheostats, or the like, it is proposed that movable separate wiper fingers, formed from small round wires, be arranged on a wiper finger carrier in parallel one to the other and in groups, with spacings provided between the groups of a width corresponding substantially to the width of the group, so that abraded matter and scuff can settle between the groups of wiper fingers without causing functional trouble.

Abstract: In connection with a potentiometer, which may in particular serve as actuator element for an electronic accelerator pedal and where a base plate carries the respective resistance and collector path(s), it is proposed that instead of providing the usual metallic inserts in the base plate to serve as sliding surface, at least one additional surface shape be applied on the base plate, preferably by printing, and that this additional shape be applied, preferably printed, on the base plate preferably by the same operation as the resistance and collector paths and using the same or a similar material having good sliding properties, and can then serve as sliding and supporting surface for at least one wiper carrier of the potentiometer.
