Stainless steel float switch - 150 mm - M10 water level sensor - 220 V water level regulator - Liquid level sensor - For water pump, swimming pool, pond

Premium Material: This liquid float switch is primarily made of 307 stainless steel, which is durable, corrosion-resistant, and heat-resistant. It is a food-grade material that does not release harmful substances.

Simple and Convenient: The liquid level sensor is a filling level control device with a simple structure and easy operation. It does not require a power supply or complex circuitry. Compared to traditional mechanical switches, it is smaller and has a longer lifespan. The floating ball in this level switch can be changed to allow for both filling and deflation.

Operating Principle: Our liquid float switch consists of a magnetic spring switch and a floating ball with magnetic material inside.

When the liquid level rises or falls, the magnetic material of the floating ball interacts with the spring-loaded magnetic contact switch to control and display the level. Instructions: There is a small mark on one end of the floating ball. If the end with this mark points upward, it is the fill fitting (normally closed). It opens when the ball rises and closes when it falls. If the smooth side of the floating ball is facing upward without a mark, it is the drain fitting (normally open). It closes when the ball rises and opens when it falls. Wide Application: This liquid level switch is extremely sensitive and can be widely used in water tanks, domestic water reservoirs, industrial water towers, fish tanks, domestic sewage pools, water pumps, and more for level control, fill level display, and overflow protection.
