ABSTRACT:
Disclosed is a variable resistor of the slide type incorporating a pair of resistor units carried on the same base plate and disposed in parallel with respect to each other. A plurality of conductive taps angle outwardly from a resistance member provided in each of the resistor units and a pair of sliders can be slidingly moved along and in contact with the series of the plurality of conductive taps in the pair of conductor units, respectively, but do not contact the resistance members directly.
