Water Level Sensor Float Switch

The water level sensor float switch is a reliable and easy-to-use mechanical device designed to detect and control liquid levels in tanks, containers, and reservoirs. It works using a floating element that rises and falls with the water level. When the liquid reaches a preset height, the float activates an internal switch, opening or closing an electrical circuit to trigger a pump, alarm, indicator, or control system automatically.

Thanks to its simple mechanical design, the float switch requires very little power and does not need complex electronics, making it highly dependable for long-term use. It is built from durable, corrosion-resistant materials, allowing it to operate safely in water and many non-corrosive liquids with minimal maintenance.

This sensor is widely used in overhead water tanks, sumps, aquariums, industrial machinery, and agricultural irrigation systems. Its ease of installation and stable performance make it an ideal solution for automatic water level control, overflow prevention, and dry-run protection in both domestic and industrial applications.
