Abstract Process for production of potentiometers having a cup shaped casing holding a part circular resistance element provided with terminals, a slider holder, a slider contacting the resistance element and a circular collector provided with a terminal superimposed on and contacting the slider and closing the casing. Such potentiometers may be formed by forming a subassembly including the casing, the resistance element and its terminals in the form of a continuous band, forming a second subassembly including the slider holder, slider and collector also on a continuous band, and coupling the two bands. In this invention, the first subassembly is formed by die cutting a continuous laminar band of conductive material to form two rows of parallel terminals oriented perpendicular to the direction of the length of the band, joined by cross strips, directly facing and longitudinally staggered relative to one another and extending inwardly from opposite sides of the band, each side of which is provided with holes also longitudinally staggered relative to the holes on the opposite side, and the terminals are coupled to the resistance element by stapling it within the bottom of the casing by bending appendages formed on the terminals.
