Low cost: ? wide using application, ? hermetically sealed, ? suit for tough environment and long life, ? Quality control takes on high priority. ? Development team support. ? After sale services. ? ? ? Working theory: ? The float switch is a device used to sense the level of liquid in a tank. ? When the float ball of the level switch rises or falls with the liquid. The magenetic force of magnet. ? which inside of the float ball will cause the reed switch to turn on( which tell the signal out) , change to Normally Closed. When the float ball move away ? from the reed switch, the reed switch will turn off, change back to Normally Open. ? ? ? Where to use ? ? ?
