The invention provides a manual switching valve which comprises a valve body internally provided with gas paths and a valve element arranged in the valve body. The valve element is provided with through holes communicating with the gas paths, the through holes are internally provided with opening-closing assemblies capable of controlling the through holes to be opened and closed, and the opening-closing assemblies can move in the opening direction of the through holes. A rotating disc capable of rotating relative to the valve element is arranged on the side, away from the gas paths, of the valve element. One ends of the opening-closing assemblies extend out of the through holes and abut against the rotating disc. The faces, making contact with the opening-closing assemblies, of the rotating disc have different heights so that the opening-closing assemblies can move relative to the through holes under rotation of the rotating disc, and accordingly opening and closing of the through holes are achieved. The manual switching valve is simple in structure, easy to implement, capable of achieving control over the multiple gas paths, wide in application range and high in safety level.
