Linear air lift switch is an important aviation component, it must be tested for fatigue life and other performance parameters before rolling out. There are some problems in the domestic relevant test system, such as single function, low degree of automation and poor universality, which directly affect the test efficiency and precision. Based on the analysis of the principle and specification of the switch fatigue test, this paper designs the mechanical execution structure and the measurement and control system, which develops labview, the corresponding control software. It realizes the test automation and improves the test efficiency and precision. Through the commissioned by the technical center of the acceptance and delivery, has a good application prospects.
