ABSTRACT OF THE INVENTION This potentiometer presents a parallelepiped casing having a quadrangular plan and is provided with recesses for the coupling of the connecting terminals which are definitely joined by plastic deformation of the pivots of the casing. It also incorporates by-pass holes for the terminals towards the ends of the resistive plate, as well as recesses for securing the collector by deformable flanges existing at the edges of the collector. The central hole of the collector is flanged, constituting a bearing for the rotor-actuated cursor, which incorporates at diametrically opposed areas thereof, as contacting elements with the resistive plate and the collector, pairs of countersunks determining rounded supports on the elements. These elements are assembled automatically and continuously. The terminals form a part of a continuous band on which they are duly stamped, as occurs with the cursors and the collectors. Each terminal-casing-resistive plate subassembly, on the one hand, and each rotor-cursor-collector subassembly, on the other, is firstly mounted, maintaining the continuity through the bands. Finally, one subassembly is secured to the other and the bands which maintained the continuity thereof are eliminated. The resistive plate is obtained from an electroisolating substrate on which a resistive paint is firstly applied and then a silver glaze, with intermediate drying phases in respective furnaces.
