Sliding Rheostat - Precision Variable Resistor
•Oxidized eureka wire wound on a porcelain tube is supported at both ends by durable, cast-aluminum, enamel painted end supports. A plastic sliding contact with laminated phosphor bronze strips is attached to the metallic bar, which in turn is mounted parallel to the tube. Three 4mm socket terminals with captive heads for electrical connection. Designed for Continuos use without overheating. Tolerance in nominal for marked value of resistance is ±5%. Resistance and current rating marked.

Resistance Box
•In polished, wooden or painted, metal case. coils of various resistance, wound non inductivity with precise adjustment of their valves, are mounted underneath an insulated, Bakelite panel. On top of this panel, heavy brass blocks are mounted, provided connection across the resistance coils, with brass terminals at ends for electrical connection. Set of milled head plug, accurately tapered to fit the holes between the brass blocks, are interchangeable and provide very low contact resistance. Accuracy .1%.
