Operation Principle :

The Operational principle of Float Switch is direct and simple  .
In General  , set one point or more points magnetic switch in sealed non-magnetic metal or plastic as required  . The dix the hollow float ball with permanent  magnet to atttract the open and close of magnetic switch to operate and control the liquid level  .The N.O and N.C is the status without injecting liquid .Due to the low price  , reliable performance ,flexible installation and multiple material choice , float switch is widely used in the level control and alarm of machinery , electrics,chemical ,household appliances ,etc .
