Description of Rotary Potentiometer
The rotating potentiometer is an adjustable electrical resistor,
which slides on the resistors by the brush, and obtains the output
voltage associated with the input voltage in the circuit.
Application of Rotary Potentiometer
Rotary Potentiometer is mainly suitable for communication products,
multimedia audio, automobile power amplifier,walkie-talkie, and other electronic equipment, but also can use for household
appliances, medical equipment. It's main functions are: volume
adjustment, light intensity adjustment, menu selection, speed
adjustment, temperature adjustment, etc.
