Adjusting potentiometer for electronic circuits, process for assembling the elements thereof and process for obtaining the resistive plate thereof

Abstract From the Canadian patent

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 …
