Control switches and Potentiometers

Control switches and potentiometers control EC fans, AC fan speed controllers or damper actuators. They generate an analogue control signal, e.g. 0-10 VDC, 0-20 mA or 0-100 % PWM. Control switches divide the analogue control signal in steps. The potentiometers generate an infinitely variable control signal. We also offer control switches for 3-speed AC fans with single-phase motor.
