BC1 type spiral arm wire resistorDetailed product description：

BC1 type rotary arm wire resistor is made by winding alloy resistance wire around a circular ceramic skeleton and fixing it with high-temperature glaze. The center of the disk is equipped with a rotating shaft to drive the electric brush on the resistor body, thereby obtaining varying resistance values.

BC1 rheostat has the advantages of high power, moisture resistance, and wide adjustment range. Suitable for regulating and controlling voltage, current, or adjustable load resistance in low-frequency AC or DC electrical equipment.
