Resistor Sliding Contact (Rheostat) of different ranges Both the max/min thermometer andResistor Sliding Contact (Rheostat) of different ranges Rheostat is wound with heavily oxidized constantan (Copper Nickel Alloy) wire on a vitreous enameled steel tube. The tube is supported on robust die cast end stands and the heavy duty sliding contact is of phosphor bronze, nickel plated for corrosion resistance. A slide rheostat (or sliding rheostat) is a circuit element that can change its resistance to act as a control circuit. During a circuit
