Float Switches


Is my sump pump doing it’s job when I listen to heavy rain in the middle of the night?

When I flush the toilet how do I know that my septic system is working as intended?

Without actually looking down the basin of the sump pump or inside your septic tank there is no way to know with 100% certainty. However, having the right systems in place can, hopefully, give you the peace of mind that there is no need to worry.

Float switches are the most important feature of any pumping system. Float switches can take on different roles as they are the devices that can tell pumps, control panels, and alarms what level the liquid is at. Inside the sealed float housing is a set of contacts that, when closed, will complete an electrical circuit.

Most float switches are the type that open or close a circuit as the level of liquid in a tank rises or falls.

The most common type of float switch is the normally open model. In a “normally open” model the control switch turns on (closes) when the float tips slightly above horizontal signaling a high level and turns off (opens) when the float drops slightly below horizontal. These are commonly used for dewatering, sump and sewage pump systems.

The “normally closed” model: the control switch inside the float turns on (closes) when the float tips slightly below horizontal signaling a low level and turns off (opens) when the float tips slightly above horizontal. These are commonly used for filling application, such as filling a cistern with a well pump.
