The 20K Ohm rotary potentiometer is a continuously adjustable resistor electrical, moving contacts slide across the resistor body when the potentiometer's turning handle or slide handle is adjusted. On/Off rotary potentiometer switches can be used for multimedia, audio amplifiers, lighting regulation and other electronic equipment.
Rotary potentiometers are commonly used in a wide range of applications, including audio systems (such as volume control), instrumentation, robotics, and electronic circuits where manual control or adjustment is required. They provide a simple and cost-effective means of adjusting voltage, current, or signal levels in a circuit.
