Product Operating Principle
A Rotary Potentiometer works by changing the position of an internal sliding contact along a resistive element. When the shaft is rotated, the sliding contact moves to a different position on the resistance track, changing the resistance between the terminals.
When connected as a voltage divider, the change in resistance can produce a corresponding change in output voltage. This allows the rotary potentiometer to provide continuous adjustment of electrical signals and circuit parameters.
The rotary operating mechanism provides an intuitive method of controlling electrical parameters. Depending on the circuit design, the component can be used for volume adjustment, brightness control, signal regulation, feedback adjustment, and other applications requiring variable resistance.
