PP Horizontal Float Switch – Liquid Water Level Sensor

Keep your tanks, reservoirs, and systems running smoothly with this reliable PP Horizontal Floating Ball Switch. Designed for straightforward installation and dependable performance, this compact liquid level sensor uses a magnetic reed switch mechanism to automatically detect and control water or liquid levels — no external power supply or complex circuitry required.

Made in Mainland China.

How It Works

The float rises and falls with the liquid level inside your tank or vessel. As it moves, the internal magnetic float approaches the sealed reed switch, triggering an open or close action. When the float moves near the reed switch, the circuit closes (ON); when it moves away, the circuit opens (OFF). This simple, self-contained mechanism makes it ideal for automatic level monitoring and control in a wide range of applications.

Frequently Asked Questions

Q: What is a PP horizontal float switch used for?

A: A PP horizontal float switch is a liquid level sensor used to automatically monitor and control the level of water or other compatible liquids in tanks, reservoirs, sump systems, and industrial equipment. When the liquid rises or falls to a set point, the float triggers the internal reed switch to open or close the circuit, activating pumps, alarms, or other connected devices.

Q: Can I adjust whether the switch turns on when the water rises or falls?

A: Yes! The switching direction is fully adjustable. Simply remove the clamp on the float switch and flip the float ball downward to change the action — allowing you to configure it to turn ON or OFF depending on whether the water level rises or drops. This makes it versatile for both fill and drain control applications.

Q: Is this float switch compatible with liquids other than water?

A: The float ball and body are made from polypropylene (PP), which offers good resistance to many common liquids including mild chemicals, oils, and water-based solutions. It is widely used in water treatment, food processing, dyeing, and hydraulic machinery. Always verify chemical compatibility with PP material before use with aggressive solvents or strong acids/bases.

Q: What are the electrical ratings for this float switch?

A: The switch has a maximum contact rating of 10W, a maximum switching voltage of 220V, a maximum switching current of 0.5A, a maximum carry current of 1.0A, and a maximum contact resistance of 100 mΩ. It is rated for EU LVD low-voltage use (below 50V AC or 75V DC in standard low-voltage applications) and operates in temperatures from -10°C to +60°C.
