Can an intermittent failure mode be possible for a microswitch? Or is the sticking failure mode same as intermittent or once it sticks it remains stuck in that position? thanks
Yes, intermittent is possible. For example, intermittent operation could be caused by worn or corroded contacts. Sticking could cause a permanent open, or close condition, or intermittent operation if the environment is such that stuck contacts may loosen from shock and vibration seen during operation. Therefore, I would not claim that “intermittent operation” and “sticking” always mean the same thing.
