How To Test The Life Of A Toggle Switch

Since the test life of the switch is obviously related to the plate moving speed at the time of test, in order to measure a correct service life, there should be a correct test pulling speed. Since the test life should reflect the service life during manual operation, the maneuvering test pulling speed should be consistent with the manual pulling speed. That is, the value of the manual pulling speed should be tested.

The switching time of the toggle switch handle from one limit position to another limit position can be measured by testing the switching interrupt time with the millisecond meter. The pulling speed can be calculated from the pulling time and the pulling distance. This speed is the average speed over the entire pulling distance. According to the actual test, the manual pulling speed is different when the operator is not in charge, and the same operator also has differences in each operation afternoon, with an average of about. Between a millimeter and a second.

At present, although there is no domestic standard for the toggle switch test, there are still foreign standards for reference. In the general specification for sealed button switches of the United States military specification I, the life test conditions stipulate that the button switch should be driven by a motorized driver at the speed of one minute, one English, and one state second. In the above standard test conditions, the test switch speed is specified at the same time as the number of tests per minute, and its value is one inch second, that is, millimeter seconds. On the one hand, it is necessary to specify a test speed, and the test speed value specified by this standard is relatively close to the manual pulling speed obtained by our test, and the difference may be caused by the difference in the manual operation speed of each prisoner. This manually operated pulling speed is reasonable for maneuvering test drive speed. For uniformity, it can be narrowed down to a millimeter second.
