Claim:
1. A method of inspecting pressure switch used for inspecting a pressure switch, the method comprising: a) providing a standard pressure generator and a pressure detector, the standard pressure generator connects to the pressure switch and the pressure detector; b) providing an inspector, and creating a plurality of data in the inspector, wherein the plurality of data comprises at least a setpoint pressure value and a pressure switch operation condition; c) electrically connecting the inspector, the pressure switch to the pressure detector; d) the standard pressure generator applying pressure on the pressure switch and the pressure module; e) recording a set pressure value and a reset pressure value of the pressure switch; f) calculating error values between the set pressure value, the reset pressure value and the default pressure value; and g) judging if the pressure switch is qualified according to the error value, wherein the method further comprises following steps after step f: f1) judging if the inspection performed three times; f2) after step f1, if the inspection not performed three times, the step moving to step d; and f3) after step f1, if the inspection performed three times, the step moving to step q, judging if the pressure switch is qualified according to the error values.
