when the triggering time is less than or equal to the time threshold, the first judging subunit (51) judges that the initial position of the microswitch is positioned in the pre-placing groove (16) and the final position of the microswitch is positioned in the test groove (14);
when the trigger time is larger than the time threshold, the first judgment subunit (51) judges that the microswitch is always positioned in the pre-discharge groove (16).
7. A microswitch testing system as in claim 6 wherein: a second judgment subunit (52) is arranged in the central control unit (5), and the second judgment subunit (52) is used for collecting current signals of the switch socket (17);
when the second judging subunit (52) collects the current signal, the current state of the microswitch is judged to be normal;
when the second judging subunit (52) does not acquire the current signal, the current state of the microswitch is judged to be abnormal.
8. A microswitch testing system as in claim 7 wherein: a recording subunit (53) is arranged in the central control unit (5), and the recording subunit (53) is respectively connected with the first judging subunit (51) and the second judging subunit (52);
when the triggering time is less than or equal to the time threshold value and the second judging subunit (52) acquires the current signal, the recording subunit (53) records that the microswitch is normal in function and is not in accordance with the times;
when the trigger time is greater than the time threshold, the recording subunit (53) records that the microswitch is abnormal in size and does not record the abnormal times.
