The float switch is a device used to sense the liquid level in the storage tank. The switch can activate pumps, indicators, alarms or other devices. By reversing the float, it can be easily converted from normally open to normally closed. 2. The float switch has a simple structure and is easy to install a liquid level controller. It has no complicated circuits and will not be disturbed. As long as the material is selected, liquid, pressure or temperature can be used in any environment. Light weight, simple working principle and high reliability. 3. Float level switches are widely used for level control and alarm in various industries such as electronics, electrical, chemical industry, water treatment, drainage and so on. 4. The working principle is through the use of a magnet to induce a reed switch. The float switch is mainly composed of a magnetic spring switch and a float. There are magnetic materials in the float. When the float moves up and down with the water level, it will touch the magnetic spring switch to detect the liquid level 5. Wide application-float switch can be used for water heating equipment such as drinking fountains, drinking fountains, water heaters, humidifiers and so on. It can also be used in water towers, drain ponds, water tanks, breeding ponds, etc.
