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.
Features of Rotary Potentiometer
Using plastic sealing structure, can effectively deal with wave welding.
Good sealing performance
Can be with positioning.
Push-pull switch or rotating switch can be chosen.
Shaft length and shape can be adjusted.
A variety of mounting methods for choice.
Application of Rotary Potentiometer
Rotary Potentiometer is mainly suitable for communication products, walkie-talkie, multimedia audio, automobile power amplifier and other electronic equipment, but also can use household appliances, medical equipment, its main functions are: volume adjustment, light intensity adjustment, menu selection, speed adjustment, temperature adjustment, etc.
