Low Level Float Switch

A low level float switch is a device used in industry to detect and monitor the liquid level within a tank or container. It is a simple, cost-effective way to remotely measure and control liquid levels for safety or efficiency. Low level float switches are mounted at the top or bottom of a tank and then connected to an external power source. When the water level rises or falls, it triggers the switch to open or close which then sends a signal indicating when maintenance is needed or when the tank is full or empty. This ensures that tanks and containers are never overfilled, preventing potential damage and spills.
