The utility model relates to a fuel gas switch which can provide the buffer and protection of a close rod, which is that a button rotating revolution shaft and a close are arranged in a switch main body in a shaft way in sequence, and a solenoid valve is arranged in a plugging way, the close rod is penetrated and arranged inside the close along the axial direction, the close rod directs towards one driven end of the button rotating revolution axis and can be topped and connected with the button rotating revolution axis, the close rod directs towards one driving end of the solenoid valve and can be topped and connected with the valve plate of the solenoid valve, when the button rotating revolution axis can be topped and connected with and drive the driven end of the close rod, to lead to the close rod generating displacement along the axial direction of the close, the driving end of the close rod can be topped and connected with and drive the valve plate, to lead to the valve plate and a sealed air hole inside the main body generating disengagement, and then, the fuel gas can enter from one air inlet of the switch main body, and flows into the inner side of the switch main body through the sealed air hole, a buffer element is arranged between the button rotating revolution axis and the driven end of the close rod, thereby, the buffer element can absorb the impact force generated when the close rod is topped and connected with and drives the valve plate, and the flow velocity of the fuel gas and the turn volume cannot be influenced.
