    I have three of my machines set up with VFD and I have used 22 mm push buttons and rotary switches. The problem is that the rotary switches tend to move over time. I know that there are locking washers available with tabs to prevent the rotation in the enclosure. I cannot seem to find a source for these and they do not come with the switches. Apparently I am calling them by the wrong name because I cannot find them with a search. Where can I find these washers or at least what is the proper name to search?

    I found a name. Anti rotation ring. Still have not found a place to purchase them other than one listing for a large lot for $89 but description does not really specify size or quantity.

    I find it hard to believe that I am the only one who has this problem.

    Hi Gordon

    Just did a search on 7/8” lock washer (22.22mm) and it came up with dozens, I got similar results with a 22.22mm search.

    If in the USA contact an electrical supply house. Square D, Cuttler Hammer, Siemens are the major brands here for those switches. The hard part will b finding an inside salesman ( Not the guy at the counter) whom will take the time to help you with such a small sale. Good luck

    Most are just thin aluminum or stainless steel sheet metal with a key tab to prevent rotating. Tin snips and Dremel time

    I finally found them. Allied Electronics. only $.40 each so the freight is more than the items.

    Thanks all.
