Abstract
The utility model relates to a plunger type water flow switch which comprises a valve body suitable for being connected in a flow passage, an electrical control switching assembly arranged on the outer wall of the valve body and a driving part arranged in the valve body and used for controlling the on-off of the electrical control switching assembly; an inner cavity of the valve body is provided with a starting area and a working area; the driving part slides to the working area from the starting area under the action of fluid; and the space formed between the driving part and the starting area of the valve body and used for allowing the fluid to pass through is smaller than that formed between the driving part and the working area of the valve body and used for allowing the fluid to pass through. The driving part can bear larger thrust force due to the smaller space for providing the fluid to pass through in the early stage of starting, therefore, the sensitivity can be enhanced, and since the space for providing the fluid to pass through in the working area is larger, the flow of the fluid can be increased.
