PP Horizontal Float Switch – Liquid Water Level Sensor

Keep your water tanks, reservoirs, and industrial systems running at the right level with this reliable PP Floating Ball Horizontal Float Switch. Built from durable polypropylene (PP) plastic, this compact liquid level sensor uses a magnetic reed switch mechanism to automatically open or close a circuit as the liquid rises or falls — no external power supply or complex wiring required.

Ideal for home water tanks, aquariums, sump pumps, dyeing equipment, food processing lines, hydraulic machinery, petrochemical systems, and more. Its simple mechanical design means fewer failure points and a longer service life compared to electronic-only alternatives.

How It Works

The float ball rises and falls with the liquid level. Inside the sealed non-magnetic tube, a magnetic reed switch activates when the float's internal magnet comes close — completing the circuit. When the float moves away, the circuit opens. The clamp can be removed and the float flipped downward to reverse the switching action (open or close on water outlet).

Frequently Asked Questions

Q: What liquid types is this PP float switch compatible with?

A: The polypropylene (PP) float switch is compatible with water, mild chemicals, and a wide range of non-aggressive liquids. As long as the liquid is within the rated temperature range (-10°C to +60°C) and does not chemically degrade PP plastic, this float switch can be used effectively.

Q: How do I reverse the switching action of the horizontal float switch?

A: Simply remove the retaining clamp and flip the float ball downward. This reverses the open/close action so the switch triggers when the liquid level drops rather than rises — or vice versa — giving you flexible control over your application.

Q: Can I use this float switch with a pump or solenoid valve?

A: Yes. The float switch can be wired into a control circuit to activate or deactivate a pump, solenoid valve, or alarm when a set liquid level is reached. Ensure the load stays within the rated limits: max 0.5A switching current and 220V switching voltage.
