Abstract
A slidable avriable resistor to be used in television receiver and in stereophonic set comprises a lower case member of an insulating material having a resistor member and a conductor on it disposed in lengthwise direction, a upper metallic cover having a long opening in lengthwise direction at the top of the cover, a slidable member of an insulating material with an arm projecting through the opening from the top of the slidable member having a brush extending from the lower side of the slidable member and sliding on the resistor and the conductor for electric conduction, and a flat rectangular plate of insulating material slidably disposed through a passage in the slidable body. By this construction should any metallic piece enter through the opening, the metallic piece is prevented from making contact with the resistor member or the conductor. Thus unexpected electric shock or damage can be prevented.
