150V AC 500k Potentiometer With Switch 15mm 3 Position Mixer Console

Potentiometer is a resistance element that has three leading ends and the
resistance value can be adjusted according to a certain change law. A
potentiometer usually consists of a resistance body and a removable brush. When
the brush moves along the resistance, the resistance value or voltage is obtained
at the output which is related to the displacement.
The potentiometer can be used as a three-terminal element or a two-terminal
element. The latter can be regarded as a variable resistor, because its role in
the circuit is to obtain and input voltage (applied voltage) into a certain
relationship with the output voltage, so called potentiometer.
