What Are Electric Float Switches Used For and Why Are They Essential in Pumping Systems?

What Are Electric Float Switches Used For?

Electric float switches, also known as level switches, are essential devices in pumping systems because they allow the automatic control of a pump’s start and stop operation based on water level. Their use not only optimizes system performance, but also protects the pump, saves energy, and prevents overflows or dry running.

What Is the Function of an Electric Float Switch?

An electric float switch detects the liquid level inside a tank, well, cistern, or pit. When the water rises or falls to a predetermined point, the float activates an internal micro-switch that sends a signal to:

• Turn the pump on (when the level rises or drops, depending on the application)
• Automatically turn the pump off once the desired level is reached

This allows the system to operate without manual intervention, ensuring safety, reliability, and efficiency.
