ABSTRACT:
The direct connection potentiometer includes a block of electrically insulative material having two opposite faces and an edge about the perimeter of the faces. An electroresistive track is provided in an arc on the front face of the block, radially spaced from a ring-shaped conductive area provided on that face. Conductive strips extend from each end of the track, and from the ring-shaped conductive area to the perimeter of the front face, where each, spaced from the others, wraps around the edge of the block to its rear face. A rotatable cursor, i.e. a slide is mounted to the block centrally of the ring-shaped conductive area and connects the ring-shaped conductive area with a selected arcuately short portion of the electroresistive track.
