Ahhh ok. I know the square root of bugger all about Altairs; I'm
mostly a DEC pdp and IBM mainframe/midrange guy. I picked up the
Altair a few years ago as an 'oh by the way' thing when I saw it at a
cheap price; I'm only just getting into it now. It does basically
work; it seems to be running some kind of ROM because when I power it
up it runs and the lights chase like a register increment thing. But
can't do much else due to broken/flaky switches.
I'll pick up some Altair schematics and see what's called for in each
switch position.

So you reckon those 7105SY9V3BE would suit the
Altair? OK I'll go
shopping.
That's just an estimate from memory. I'd have to dig my 8800 out, dust
it off and make measurements.
Note that the part I linked to is center-off-momentary SPDT. Clearly,
not all of the switches on the Altair are like that.
There are, of course, lots of other switch vendors, NKK, e-switch...
But the C&K selector is by far the easiest to use.
