The magnetic float switch is a device used to sense the level of liquid in a tank. There is a magnet in the float ball and a magnetic reed switch in the rod. When the liquid level rises, it drives the float ball up close to the reed switch inside the rod. The magnet then force the two magnetic contacts inside the switch to connect, which allows current to pass. When the reed switch connects the circuit, it’s called “Closed.”

Application: can be used for water dispenser, water heater, solar energy, air conditioning, humidifier, bathroom equipment, sales machine, oil tank, water tower, chemical liquid level control, kitchen equipment, water heater and other water heating equipment, such as dry burning water level sensor.It is widely used in automobile, industrial equipment, agricultural equipment and household appliances.
