<p>An improved potentiometer characterized in that it comprises a flattened orthogonal shaped enclosing body (1) with one of its larger sides open and forming an aperture allowing a quadrangular plate (8) of resistor material to be seated therein, the internal face of the said plate (8) carrying an electro-resistant track in the form of an interrupted circular corona, the extremities of which have, each one, attached thereto a terminal (2, 3) connecting to the exterior, the said plate (8) being held in place by a closure cover (23) of the enclosing body, in the shape of a quadrangle, this cover (23) being inserted by its edges and in its centre having an axial projection (24) which is introduced into a central aperture in the plate (8) carrying the resistor track. <IMAGE></p> |
