Abstract
An illuminating type linear resistor for volume control having an insulating substrate; a pattern of resistor and collector formed on one surface of the insulating substrate; a lead formed on the other surface of the insulating substrate for supplying power to an LED; a slider mount assembly surrounding the insulating substrate and separatably formed into first and second slider mounts; a knob provided on the first slider mount which knob is formed at its upper end with a receiving portion for receiving the LED; a first slider mounted on the first slider mount and adapted to slidingly contact the pattern of resistor and collector; a second slider mounted on the second slider mount and adapted to slidingly contact the lead; and a clip provided at an extension of the second slider for holding a terminal of the LED which clip is received in the knob of the first slider mount.
