    Tips: Working principle of float liquid level switch

    Using the magnetic float of the float liquid level switch to rise or fall with the liquid level, the sensor can detect the action of the reed tube chip at the set position in the pipe, and send out the contact on (off) conversion signal.

    In airtight nonmagnetic conductivity tube fitted with one or more of the dry reed pipe, then the tube through one or more hollow and internal ring magnets floating ball, rise or fall of liquids will drive the floating ball move up and down together, so that the nonmagnetic conductivity tube suction reed tube or disconnect, so as to output a switch signal.

    Durable construction
    I install this float switch on my water tank. It has durable construction, great wire and insulation. If the water in tank drops, the pump turns off and it opens the ball valve to fill the tank. Very convenient!
