Test device for automatically controlling switching machine

The utility model provides an automation starting-up and closedown testing device, which can perform the starting-up and closedown action repeatedly to a computer mainboard, wherein, the device comprises a microcontroller, a controller, and a display module. The microcontroller is electrically connected with the computer mainboard to be tested and is composed of a receiving module which is electrically connected with the computer mainboard and used for receiving a starting-up signal starting the computer mainboard; the control module is connected with the receiving module and used for judging whether the computer is started successfully or not by the mainboard, and controlling the computer mainboard to perform the times of starting-up and closedown actions; the display module is connected with the control module, and used for displaying the state of starting-up and closedown of the computer mainboard. The undesired mainboard is detected by the given times of repeatedly performing the starting-up and closedown
