The basic knowledge of Kailh Potentiometer

Potentiometer has three leading-out terminal,the value of resistance can be adjusted by the certain resistance element change.

The potentiometer is consist of resistance element and movable brush.when the brush moves along the resistor,the output terminal and displacement forms certain relative resistance value and voltage

 

The potentiometer can be used as three terminal component and two terminal.the latter one is regarded as variable resistor,because of its role in the circle to obtain and output voltage(external voltage)in a certain relationship output voltage,so it’s called as potentiometer
