This magnetic float switch works according to the float principle and by using magnetic transmission ( permanent magnet / reed contact ).
A float with a built-in magnetic system is conducted along a non-magnetic guide tube. Due to the magnetic field of the permanent magnet,
a reed contact ( protective gas contact ), located in the guide tube, will be activated, after a defined height has been reached.
As a result the electric circuit will be closed or interrupted, depending on the switch function. Depending on the number of preset switching functions
and their intervals, the device will be equipped with one or more floats.
