Product Description
      The rheostat uses the constantan wire or nichrome wire as the elements of resistance to circle on the framework of round chinaware . Except of the sliding surface , all the elements of resistance are covered the thermostatic enamel dope and agglutinate on the bottom plate of chinaware. In addition , the center of the chin aw are is set rotation axis which can drive the brush holder and electric brush to slide. so as to change the resistance value .
