I. Introduction: The test bed for special equipment durability testing of the ignition switch, the ignition switch can be simulated using real vehicle test can detect ignition mechanical durability and electrical performance parameters of performance parameters of the switch can be carried out simultaneously or similar three different types of switches endurance test. The main technical features and parameters: 1, the contact pressure drop testing, pass, off load and performance testing with 2 contacts each gear, pop the latch is normal, gear shifting test; 3, using the robot to achieve ignition switch to start the file The automatic release function; 4, the system automatically eliminate cumulative errors, accurate and reliable 5, divided into high and low temperature test bed type, servo motor driven, stepper motor-driven variety of series two, to meet the standards: 1, QC / T 504-1999 "car with the ignition switch technical conditions." 2, QC / T 198-1995 "auto switch General technical conditions." 3, JB 3126-82 "auto switch - as technical conditions." Third, the test parameters: a DC power supply: 0 ~ 30V adjustable, 0 ~ 100A adjustable. 2, plug angle: 0 to 60 degree adjustable. Fourth, test objects: a car ignition locks, trunk locks, door locks, hood locks and cylinders. 2, motorcycle ignition locks and cylinder
