Dual Ball Float Switch – Stainless Steel 304 Water Level Sensor
Dual Ball Float Switch – Stainless Steel 304 Liquid Level Controller
Keep your water tank, pool, or reservoir running smoothly with this reliable Dual Ball Float Switch. Built from corrosion-resistant 304 stainless steel, this mini float switch automatically senses the liquid level inside any tank or vessel and triggers your pump or valve accordingly — giving you hands-free water level management with no guesswork.
Whether you're managing a home water storage tank, a garden pond, an irrigation reservoir, an aquarium sump, or an industrial container, this compact dual-ball design offers consistent, accurate liquid-level sensing. Available in 7 color options to match your setup or make identification easy in multi-circuit installations.

Frequently Asked Questions
Q: What does a dual ball float switch do in a water tank or pool?
A: A dual ball float switch senses the level of liquid inside a tank, pool, or reservoir. As the water level rises or falls, the two float balls move accordingly and trigger a connected pump or valve to either fill or drain the vessel — providing fully automatic water level control without manual monitoring.
Q: What material is this float switch made from, and why does it matter?
A: This float switch is made from 304-grade stainless steel, which is highly resistant to corrosion, rust, and scale build-up from prolonged water exposure. This makes it an excellent long-term choice for wet environments like tanks, pools, and irrigation systems where lesser materials would degrade quickly.
Q: What types of systems is this dual ball float switch compatible with?
A: This float switch is compatible with a wide range of liquid-level control applications including home water storage tanks, swimming pools, garden ponds, aquarium sumps, irrigation reservoirs, and general industrial containers. It works with most standard pump and valve control circuits.
Q: Why choose a dual ball float switch over a single ball version?
A: The dual ball design provides greater stability and accuracy in liquid-level detection compared to single-ball switches. The two-float configuration helps reduce false triggers caused by water turbulence or surface agitation, resulting in more consistent and reliable automatic operation.
