The invention relates to a switch contact performance detection system which comprises a first connecting end for connecting a common end of a detected contact; a second connecting end used for beingconnected with a static contact of the detected contact; a power supply unit which is respectively connected with the first connecting end and the second connecting end to form a loop; a driving unitwhich is matched with a movable contact of the detected contact and drives the movable contact of the detected contact to act so as to trigger the detected contact; a monitoring unit which is connected with the first connecting end and the second connecting end and is used for monitoring an electric signal of the detected contact to generate a corresponding test waveform; and a processor which isconnected with the monitoring unit and is used for judging the contact performance of the detected contact according to the test waveform. According to the invention, the performance detection of theswitch contact can be effect
