ABSTRACT:
It should be possible to adjust without difficulty the moment of friction curring during rotation on a variable resistor. A bolt (11) is provided for this purpose for holding a rotating part (13) axially in position with a base component (2). A tap (24) is brought into contact with a resistance track (5) rotating in the base component (2) in a radial direction to the axis of rotation (14). The bolt (11) can at the same time be used for securing the variable resistor (1) and as the electrical connection for the tap (24).
