There is water flow through the water flow switch, pushing the copper plate installed with the magnet, so that the two induction iron pieces of the reed pipe are attached to each other by the magnetic field of the magnet, the voltage passes through the induction iron piece, and the relay is driven to start the water pump. Similarly, there is no water flow through the water flow switch, and the pump also stops working to protect the pump from emptying.
