A pressure switch parameters testing system that can inspect five products at the same time was designed for measuring continuity resistance, insulation resistance, actuation pressure and de-actuation pressure. The system utilizes a virtual instrument technology to build a virtual instrument testing system based on hardware platform with computer and boards and software platform with LabVIEW. Four-terminal connection method is used to realize the measurement of micro-resistance. Relay logic is employed to achieve the test of five products automatically. And the qualification of products is judged according to the measurement results. The result shows that this system has the reliable of operation, high accuracy of measurement and high efficiency.
