A rotary potentiometer is a variable resistor (electromechanical component) that works by moving a wiper across a resistive element to obtain an output voltage related to the input voltage, hence its name. The main parameters of a rotary potentiometer include linearity, resistance value, rated power, rotational noise, temperature, resistance variation characteristics, and insulation impedance. Rotary potentiometers are primarily used in communication products, walkie-talkies, car amplifiers, multimedia speakers, smart home devices, computer peripherals, etc. Their functions mainly include volume adjustment, light intensity regulation, menu selection, speed control, and temperature adjustment.
