FSP-60-1 1" NPT Liquid Paddel Flow Switch
When the fluid rushes to the blade, the blade swings, which changes the relative position between the magnet and the reed contactor, which excites the contactor to close or open. Once the fluid is interrupted, the blade returns to the initial position, and the reed contactor is activated again. The mutual repulsion of the two magnets provides the force required for the flow switch to reset, and the contactor returns to the previous state.
