The switch may actuate a pump, an indicator, an alarm, or other device.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. Feature:This float switch is a simple structure,easy installation liquid level controller.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.Light weight and simple working principle,high reliability.The float level switch is widely used in electronic,electrical,chemical,water treatment,drainage and other walks of life level control and alarm.
