Feature: Simple structure. Long service life. 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.
Note: Float used in conjunction with the relay can not be directly used with the power supply. Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.
