PP  Magnetic Reed Switch Float Switch

Product Description


Product Description


Working theory:


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.”

Product Application

The magnetic float switch can be used to monitor liquid level in watering machine, water heater, solar energy, air conditioner, vending machine,BSD-P, water dispenser, Humidifier, dehumidifier, fluid control, a pump, alarm device, moisturizing machine , bathroom utensil , oil tank , water tower and chemical industrial ,etc. And widely applied in motor vehicles, industrial equipment, agricultural equipment and household electrical appliances in the future.
