[sdiy] Square holes

[David Cornutt]

Anyone know of an easier way to cut good square/rectangular
holes in a panel?  After going over the extortionate prices for
toggle switches lately, I happen to notice in the Mouser catalog
that there are some snap-in mini rocker and paddle switches
that are available for about half of what equivalent toggle
switches cost.  But of course, you've got to cut that darn square
hole in the panel.
