Most of the failures I've seen have been due to heavy carbon on the
contacts, usaully a little snadpaper or file and your back in Biz.  While
many yaers switches work, I like the newer years with the LEDs as they
almost never die.

I have had luck drilling a small hole about halfway up in the old switches
and spraying contact cleaner in them. This works for me on about 75% of the

switches I've attempted.
