A float switch detects the level of water in a container, such as a tank or well. They can be set to open or close when liquid reaches a preset level, helping to prevent overfilling and underfilling.

To fit a vertical float switch, attach it through the top or bottom of your tank. For safe use, be sure to position the mounting thread and cable entry above the highest level of the liquid.
