Typical float switches are normally resting in the closed position meaning the circuit is incomplete and no electricity is passing through the wires yet. The two leads will be close within the housing but they will not be touching.

How a float switch works. 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. You will see how a tethered float switch turns on and off a superior pump. The switch may be used to control a pump as an indicator an alarm or to control other devices. Old float switch working principle. 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. It does this depending on the water level in the sump pit of your pump.
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. The basic work of a float switch is to detect if there is flooding in the sump or not. In this video you will learn how a superior pump tethered float works. 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. 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.
Another common type is a float that raises a rod to actuate a microswitch. How does a magnetic float switch work. Split into three main parts a typical horizontal float switch consists. Established as the standard instrument for industrial level measurement. 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. Components of a typical horizontal float switch.
With the more common reed switch the device will have two electrical contacts sealed in a glass casing. Older float switches work by opening and closing circuits dry contacts as water levels rise and fall. On a circular float ball the sump pump float switch relies so that it can easily measure the water level. When the contact between the leaves is made a current can flow via the closed leaves and a switching signal will be detected. It works on switching the sump pump on and off. Trusted reliability in aggressive environments.
One type of float switch uses a mercury switch inside a hinged float.
