Trimmer Potentiometers FAQ


What will happen if I continue turning the adjustment knob (driver plate) of a product that does not have a rotation stopper?

If you turn the knob only a few revolutions, there will be no particular problem concerning the product quality.

However, please note that neither the electrode nor the resistive element exists past the maximum electrically effective rotation angle, so the No.2 terminal will be open circuit.
