How do Electric Float Switches Work?

As the electric float switch is raised or lowered by varying liquid height, a magnet is moved closer to or further away from a switch enclosure. As the magnet moves closer, a reed switch in the enclosure closes. As the magnet moves further away, the switch opens. The arm containing the magnet also acts as a counterweight for the float. Our electric float switches are small and will operate in liquids with a specific gravity as low as 0.4. The interface type will operate with a specific gravity differential as low as 0.1.
