Float Switches
Float switches detect liquid level with a buoyant float that rises and falls with the liquid. They control pumps, valves and alarms with simple, dependable operation.
Float Switch Types
- Cable floats – sumps and lift stations
- Vertical floats – compact tank mounting
- Side-mount floats – install through tank walls
- Multi-level floats – several set points on one stem
Choosing a Float Switch
Select float material for the liquid and temperature, and check electrical ratings against your load. Use relays for large pumps.
Nisco supplies float switches for tanks and sumps.

- A float switch has a buoyant float (foam, plastic, or stainless ball) that rises and falls with the liquid level. As the float moves, it actuates an internal magnetic or mechanical switch that opens or closes a contact at a fixed level. Used for high and low alarms, pump start/stop, and overflow detection. Cheap, reliable, and the most common point-level device in the world.
- Side-mount switches thread into a side wall of the tank, with the float swinging on a horizontal arm. They detect a single fixed level (where the arm sits) and are limited to clean fluids. Top-mount switches drop a vertical stem into the tank from above, with one or more floats sliding on the stem to trigger switches at different heights. Top-mount handles multiple set points in one device and works on tanks where side mounting isn't practical.
