In the case of a float switch with a reed contact with a normally open function on applying a magnetic field the leaves are brought into contact. Another common type is a float that raises a rod to actuate a microswitch.

How a float switch works. In a single point float switch a low alarm sensor will trigger an led light on your control board in a multi point float switch a low alarm could trigger the led light to turn on and send a signal to turn on an automatic water pump to refill the water back to the preprogrammed water level. Old float switch working principle. A float switch is a type of level sensor a device used to detect the level of liquid within a tank. Most float switches are the type that just open or close a circuit as the level of liquid in a tank rises or falls. Most float switches are normally closed meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point resting on its bottom clip for example when a tank is dry. With the more common reed switch the device will have two electrical contacts sealed in a glass casing.
Float switch can control your water tank level it will make on and off your water tank motor automatically yiu dont need to on the motor and even dont need to off the motor by using this. Split into three main parts a typical horizontal float switch consists. The basic work of a float switch is to detect if there is flooding in the sump or not. The two leads will be close within the housing but they will not be touching. Established as the standard instrument for industrial level measurement. Typical float switches are normally resting in the closed position meaning the circuit is incomplete and no electricity is passing through the wires yet.
Trusted reliability in aggressive environments. It works on switching the sump pump on and off. The switch may be used to control a pump as an indicator an alarm or to control other devices. On a circular float ball the sump pump float switch relies so that it can easily measure the water level. Older float switches work by opening and closing circuits dry contacts as water levels rise and fall. It does this depending on the water level in the sump pit of your pump.
How float switches work the purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. When the contact between the leaves is made a current can flow via the closed leaves and a switching signal will be detected. How does a magnetic float switch work. You will see how a tethered float switch turns on and off a superior pump. Components of a typical horizontal float switch. One type of float switch uses a mercury switch inside a hinged float.
In this video you will learn how a superior pump tethered float works.
