Description of Rotary Potentiometer
The rotating potentiometer is an adjustable electrical resistor,
which wipes on the resistors by the wiper, 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 walkie-talkie,
multimedia audio, automobile power amplifier and other electronic
equipment, but also can use household appliances or medical
equipment. It's main functions are: light intensity adjustment,volume adjustment, menu selection, speed adjustment,
temperature adjustment, etc.
