Yup, the old Black and Decker speed lathe, did that myself. Turned
some firing pins out of drill rod that way long before I ever had a
lathe or could dream of owning one.

If the O.P.'s switch is part of a consumer electronic unit, chances are
the importer won't have ANY parts, it's probably proprietary, best bet
is to rob another unit or buy a replacement for it. Most stuff isn't
built to be serviced anymore and they make it damned hard to try. It
usually isn't worth the time given the falling cost of consumer
electronics these days.
