What is a Pear-Shaped Float Switch?

A pear-shaped float switch is an essential device used in wastewater and drainage applications to prevent pumps from running dry. It is recommended to use at least one float switch in such systems. Due to the high fluid density in wastewater and drainage applications, heavier, acid-resistant, and pear-shaped float switches that can easily float in water are preferred.

The float switch activates the pump by sending a signal when the water level rises, and when the water level drops, it sends a stop signal to protect the pump. Float switches provide a reliable control mechanism, especially in water drainage systems in industrial and commercial applications. Additionally, they help save energy and extend the pump's lifespan. Selecting the right float switch is crucial for ensuring the performance and durability of the system.
