The invention discloses a switch mechanical characteristic dynamic performance detection system, and relates to the technical field of switch mechanical characteristic detection. The method comprises the following steps of: acquiring a characteristic current signal or a voltage signal of a switching characteristic current, performing I-V conversion on the acquired current signal, or amplifying the acquired voltage signal, outputting a processed signal, and extracting a form opening and closing weighted composite filter at the same time; the summator is used for adding and superposing the signal output by the current feature extraction processing unit and the sine frequency sweeping signal generated by the signal generation unit, and selecting and outputting a signal output by the summator and the sine frequency sweeping signal output by the signal generation unit for an open-loop test; and the frequency domain analysis unit is used for receiving the signal selected and output by the system dynamic performance
