Rheostat

For use as series resistors or potentiometers. Open type slide wire type with a variety of resistance and current carrying capacity. Copper-nickel alloys wire is oxidised to provide perfect insulation. Phosphor bronze contact provided on metal chrome plated slider-rod to give rapid and smooth adjustment. Three 4 mm socket terminals are provided. One at each end of the wire and the third at one end of the slider-rod thus the Rheostat can be used as potentiometer also. Resistance in ohms and current carrying capacities are engraved on it. The end support are made of metal/bakelite. Diameter 43 mm.
