What is a Float Switch?

Definition of Float switch in Construction
A float switch is a switch that is activated either electronically or mechanically by a floating device and or sensor.

The float switch is normally used within a vessel or container that stores a fluid. The container can be a storage container that requires an alarm for low or high levels, or simply an indication of the level of product within the tank. Or the float switch can monitor a constantly changing level within a containment vessel that needs to be continuously monitored. The float switches most commonly witnessed are, the float within your toilet’s water tank, or the float in the basement sump, that activates your sump pump. Float switches of all kinds have controlled fluid levels for many years, now with electronic means of signalization, the float switch has evolved from simply a floating ball on an arm to highly sophisticated control mechanisms.
