For square holes, I use a nibbler, but results are not great.  So
I open/clean them up with a dremel or file.  Lots of work, and
unnecessary when I have 2 other options ...

- Use round switches (Sure you've figure this out already :-)

- My latest project will have 12mm square caps flush mounted
   to the panel (w/square holes).  But the whole panel and
   switches will be covered with a transparency on which I
   have the switch functions/locations printed.  It's sort
   of like a membrane (???) panel -- totally flat on the top.
   I just haven't figured out how long the transparency would
   last.  Other reason I'm doing this is so I can have words
   reverse-printed on the transparency so that I can light
   them up from behind.  And this can be done with round
   switches as well I'm sure.

Cheers,
-Neil.
