ABSTRACT:
A potentiometer has a substantially rectilinear slide spring (2) which rests on a defined inclined support surface (4) of the spring carrier (1), being supported, in one direction, at the front edge (7) of this support surface and, in the other direction, projecting into a recess (5) of the spring carrier serving as a thrust bearing for the vertical force. The slide spring (2) is anchored firmly on the spring carrier by means of a tongue (12) bent upwardly and by a post (13) of the spring carrier.
