The invention provides an air pressure switch, and mainly solves the problems of the existing air pressure switch that when an annular diaphragm is unevenly stressed, the annular diaphragm has high probability of shaking or deviating, and accordingly, the air pressure switch fails and the performance is unstable. The air pressure switch is characterized in that a pin is further arranged, the pin comprises a fixing part, a positioning part and a wiring part, the fixing part is fixedly connected with a movable spring, a positioning hole is formed in the positioning part, a convex pole is inserted into the positioning hole, and the wiring part is connected with a plug assembly through a lead. The air pressure switch has the advantages that the pin is arranged on the movable spring, and the convex pole is inserted into the positioning hole; the structure is simple and compact, movement of a push plate is limited, and the performance of the air pressure switch is more stable.
