They are actually pretty common C&K toggle switches, especially if it is not one of
the momentary ones. DigiKey, Mouser, etc. Or eBay are places you can start your search.

While I'm still struggling with the powers supply in the /84, I
decided to also take a good look at the /05. Amazingly, the power
supplies on this one (1972) are 13 years older than those on the /84
(1985), yet their outputs look absolutely perfect. Plugged in the
cards, and it seems to work, apart from one annoying little thing: one
of the front panel switches is bad. I noticed it when I was
depositing, then reading back some data, then took a multimeter to
determine that it's the switch itself that's broken. Cosmetically it
looks ok, but it doesn't work. It's just one of the address/data
switches, all other switches work fine. Are there any replacements for
these switches to be found?
