PCB potentiometer. Mini potentiometer for use on a PCB (printed circuit board). Potentiometers are a type of variable resistor. On ones like this,turning the small slotted knob (gold,lower centre) varies the resistance to electric current across the metal contacts (small wires). Potentiometers are used in devices such as light dimmers and volume controls. Tiny ones like these are mounted onto printed circuit boards | |
