[0040] In some embodiments, the aging test unit 1 further comprises a power supply change-over switch 15, a first power supply inlet end of the power supply change-over switch 15 is used for being electrically connected with the power supply 200, and a power supply outlet end of the power supply change-over switch 15 is used for being electrically connected with the power supply inlet end of the composite switch 100 on the plurality of test stations 13.

The communication connection between the controller 111 and the compound switch 100 is usually RS485 communication, and the real-time data generated by the compound switch 100 during the aging process can be displayed on the man-machine interface or inquired through RS485 communication transmission. In addition, the control module 11 in the communication control mode can also read the fault code of the compound switch 100, and display the position of the compound switch 100 with fault through the display device, without the need for artificial investigation, thereby the efficiency of investigating the compound switch 100 with fault is improved. It needs to be explained that in the present application, if the compound switch 100 to be aged has a communication interface, the communication interface of the controller 111 is connected, so that the position of the compound switch 100 with fault can be obtained in time. If the compound switch 100 to be aged does not have a communication interface, at least one compound switch 100 with fault in the group is determined through the aging monitoring module 12, after the group fault is determined, the compound switch 100 with fault in the group is artificially investigated.
