Magnetic Float Switches
Theory of Operation: As the magnet rises and falls along the stem it pulls open or closed a manetic reed switch. Magnetic Floats are extremly flexable form of point level control. Multible floats can be located anywhere along the stem and the stem can be sized for the specific application.
