By Journal of Sex Research;
(2)Do not obtain the inspection of realistic model, the complexity of working condition makes theoretical and achieved reliability and life-span have
Certain gap;
(3)Application difference it is difficult to the reliability under not in the same time is measured and compares to dissimilar travel switch,
Replacing, checking maintenance cycle cannot be determined.
Therefore, it is possible to the reliability research experiment to dissimilar travel switch for practical situation, obtain internal
The parameters such as dynamic contact resistance, response time, carry out dynamic evaluation to its reliability, draw its life-span distribution, thus
Go out the checking maintenance cycle of dissimilar travel switch, industrial safety is produced and reduces with accident rate there is important reality meaning
Justice.
