Abstract

Improved potentiometer, which is characterized, essentially, by the fact of being constituted by the substantial combination of a base of refractory material and substantially discoidal that on its front face has the corresponding winding of resistive wire and the discoidal plug of the current outlet, while in its rear face such base comprises the terminals connected mechanically and electrically with one of the ends of that winding and with the insert of current, respectively, whose base in question presents in its front and as an extension of its own structure, some symmetrical prominences in which the paths are riveted to those of a metallic piece of laminar structure and as a dome that is equipped with a central drill through which a rivet piece with a tubular constitution and its surface is incorporated. External thread to receive the screw of the conventional clamping nut in position of the potentiometer in its place of placement and through whose rivet piece emerges to the outside the axial and rotary maneuvering organ of the apparatus, which at its rear end and in addition to a flat annular retaining flange, has a blind hole axial quadrangular cross section, in which is located one of the extremities of a metal square constituent of the axis of rotation of the rotating contact-cursor, whose square has its other extremity located, for the purpose of support and support, inside the junction rivet between the said discoidal plug insert and its corresponding terminal.
