ABSTRACT:
A sliding rheostat includes two slider supports mounted to a support member between a pair of resistance base plates and in the direction that the slider supports move. Screws are mounted between the corresponding sliders and the support member to adjust the positions of the sliders relative to the support member, thus permitting the points at which the sliders are in contact with their respective resistance base plates to be placed in a line.
