Abstract

In the case of a movable collector for potentiometers, adjustable resistors and the like, it is proposed to arrange moving individual wiper fingers, consisting of small round wires, parallel to one another in groups or to a wiper finger carrier, and intervals corresponding approximately to the width of the group, so that wear products and dust can be deposited between the wiper finger groups without interfering with operation. <IMAGE>
