• Easy to use.
• A float switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or other device.
• Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating etc.

Working theory:

• One or more reed tubes are mounted in a closed, non-permeable tube.
• Then the tube is passed through one or more of the hollow and internally floating magnets.
• The rise or fall of the liquid level causes the floating ball to move together, thereby causing the reed switch in the non-permeable tube to be actuated to open or close and output a switching signal.

Package included:

• 1 x Water Level Switch
