Float level switches technology
All float operated liquid level controls operate on the basic buoyancy principle which states “the buoyancy force action on an object is equal to the mass of liquid displaced by the object.” As a result, floats ride on the liquid surface partially submerged and move the same distance the liquid level moves. Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm.

- May be wired for automatic fill or empty cycles
- Dry contact switch mechanism
- Cable CSA (SJTO) approved
- Switch chatter eliminated with moving ballast
- Single float with simple control circuit
Options
- Mounts by cable tie or optional cable weight
Operating principle
The moving ballast causes a flipping motion of the float to provide positive switching action.
