Side Mount Liquid Level Control Switch (Out of Stock)

 

This switch will open or close the electric circuit when liquid level reaches a specific position. It can be used to activate a pump when liquid level is low, or to open the heating circuit to prevent the damage of the heater.   For cutting off the heating circuit when liquid level is low, the sensor tip should be mounted downwards as shown.  Since the switch is rated for 0.4 Amp, a typical wiring is to put it in series with relay (or solid state relay) control loop.
