Features:
*Made of high quality material, durable and practical to use
*A float switch is a device used to sense the level of liquid within a tank. It may actuate a pump, an indicator, an alarm, or other device.
*Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating etc.
*All imported dry reed pipes are used, and the contact life can reach 1 million times;
*The reed switch and lead are completely isolated from the measured medium, and can be used reliably under high temperature and high pressure;
*Multiple installation methods: thread, flange, chuck, etc.,
*It can also meet the different needs of various environments;
*Lightweight.
*Apply to many fields: water treatment, food, medicine, chemical industry, electronics, shipbuilding and other industries.
*Simple theory. Stable and reliable performance. Long working life;

Working theory:
*More reed tubes are mounted in a closed, non-permeable tube.
*Then the tube is passed through   or more of the hollow and internally floating magnets.
*The rise or fall of the liquid level causes the floating ball to move together, thereby causing the reed switch in the non-permeable tube to be actuated to open or close and output a switching signal.
