The design scheme of test bed used to test automotive ignition switches
Automotive ignition switch is a very important part in a vehicle. The quality of ignition switch will affect directly the vehicle's starting ability. So every batch of ignition switches need to be sample surveyed according to strict technique and technology requirements published by China Government. The ignition switch's test conditions, test items, and targets are also defined. According to the above-mentioned standards, the ignition switch's test bed we designed has the functions as: 1) Display how many work cycles have passed while the current samples are being tested. 2) Display in real time every step's current passing through the samples. 3) Can be set flexibly the number of steps and the angle of every step according to different types of ignition switches. 4) Can be set flexibly the rotary speed and residence time. 5) Capture the number of work cycles when first error appears in each step. 6) Can be set the number of work cycles after which keys can be inserted or pulled out of the samples. Can be set the number of work cycles after which electric current or voltage begins to be measured.
