Liquid Level Control Switch. W/ Braided Detachable Cable


  • Model: FSW2


Product Description:

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 0.8 Amp, a typical wiring is to put it in series with relay (or solid state relay) control loop. 
This item comes with 8 ft braided cable with mating mini connector. The braided cable added an extra layer of metal braid between the TEFLON layers for more protection. The type of panel mount connectors is our mini connector (two pin). The mating connector has a 2 ft 3 inch (700 mm). User can use this cable without any soldering work.
