Float level switch are designed for control of water level in steam boilers and other vessels and storage tank A float with a mounted magnet slides in depending on the change of level. It is connected to feed pump, signal unit or fuel supply.
 
The vertical movement of the float magnet in the pressure tube simultaneously actuates the secondary and switch magnets within the switch mechanism, to operate the contacts.
This magnet system enables the float magnet to pass the switch and actuate switch mechanisms at other levels. Switch mechanisms which are actuated will not reset until the float magnet actuates the switch mechanism on a falling level.
 
The float or displacer drives a stainless steel sheathed permanent magnet attached to the float rod in the glandless pressure tube. As the float rises and falls with a changing liquid level the float assembly moves upwards inside the pressure tube.
