1.A float switch is a device used to sense the level of liquid within a tank.
2.The switch may actuate a pump, an indicator, an alarm, or other device.
3.It can be easily converted from normally open to normally close by inverting the float.
4.Note: because the current that the switch can carry is much little(0.5A), you must use a relay or contactor when it is connected by a load, relay and contactor are not included here.
1.This float switch is a simple structure,easy installation liquid level controller.
2.It does not have a complex circuit,will not be disturbed,as long as the material selection,liquid,pressure or temperture can be used in any environment.
