walt rapp posted:Rob: The fact that 6 out of 36 have had the exact same issue coupled with the fact that my switches are on a Christmas-time only layout, well, the "million or half that" comment isn't matching to my experience with these things. I know it's the plunger action and not an allignment issue because if I gently push on the 'action bar/lever' the cycle completes.
The life rating of the snap switches is for the internal switch operation of the snap mechanism - your issues appear to be all external involving getting the plunger pushed in far enough to activate the actual mechanism - whether it's the arm getting deformed, the switch not being positioned in relation to the cam, cam wear, or a combination.
If the plunger has developed/worn to a point that it actually requires to be pushed in further than the working ones, then that would be an internal failure. Usually, the snap switches fail completely when the the snap leaf inside becomes deformed or broken.
