A potentiometer element housed in an anchoring body which is provided at the extremities of its walls with a plurality of lugs which are deformable angularly in order to hold the potentiometer element, also incorporating a control shaft wherein the insertion extremity of the shaft presents a groove which forms two elastic lugs which, when brought closer to each other permit the removal and replacement of said control shaft. The potentiometer element is also characterized in that, in the system of contacting the resistive track with the ends of the corresponding terminals, there are provided two or more protuberances which act as springs, and terminals present a notch so as to facilitate the bending and to reduce the recovery effect.
