In daily life, when water is used, the water pressure is often insufficient, and an automatic water pump is installed at the tail end of a pipeline for pressurization. Generally, a flow switch is generally adopted by an automatic booster pump as a device for sensing flow (whether the flow switch is integrally installed with a pump body or externally connected to the pump body), and the flow switch cannot detect that water flow passes through the device to cause that the water pump is not started and cannot achieve a boosting effect. The problems that the water flow is small, the experience is poor, or related equipment in the pipeline cannot work normally and the like are caused.

At present, the control principle of the flow switch on the market is as follows: when water flows through the water pump, the tongue piece in the flow channel deflects to drive the magnet at the top to be close to the external reed pipe, so that the reed pipe outside the flow channel is closed, and the water pump operates to pressurize the pipeline; when no water flows in the flow channel, the tongue piece resets under the action of the return spring, the magnet is far away from the reed pipe, the reed pipe is disconnected, and the water pump stops working.
