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. Potentiometers come in different shapes and sizes. They can be rotary - type, which is the most common, with a knob to rotate for adjustment, or linear - type, where the adjustment is made by sliding a contact along a straight track. They are widely used in many electronic devices such as audio equipment for volume and tone control, in lighting systems to adjust brightness, and in various kinds of sensors and control circuits.
