My apologies for all the fuss. Again: who knew this was difficult?

According to Mike Douglas AKA deramp .. the American Switch brand was used in the original Altair not C & K.
S1 Toggle Switch On-None-On (Silver) APEM 5236AB S10-S25 Toggle Switch On-None-On (Gold) APEM 5236CDB S2-S9 Toggle Switch (On)-Off-(On) (Gold) APEM 5237CDB
Take this as you wish but I do value Mike's opinion on this
Um, I also saw this information 1) in the VCFed discussion list referenced earlier in this thread and 2) on notes it referenced on the deramp site, about a MITS Altair front-panel replica. But... But: those references to a replica, have confused me, as to whether the original Altair switches were of that brand; or if these identified switches are reasonable replacements; or if these are for the replica. Pardon my confusion. Also: in my most-prior post here, I acknowledge I *do not know* what brand was in-use. My error, to suggest C&K. That's why I'm asking. Again: proof beyond doubt, would be a photo of an original switch, in place, on an original front panel. Such a photo seems to be surprisingly hard to produce, hard to find. I certainly don't want to disassemble my MITS Altair just to take an internal photo. And my apologies, this is not a "personal trust" issue. I appreciate the identifications given, it's a "lead". My request for evidence is not unreasonable. I'm surprised it's so obscure! At least in year 2020. I've seen BUNCHES of photos of lots of MITS boards. But not of the original front panel, in profile. I'll be sure to provide those, should I tear my Altair apart. (No it's not for sale). Regards, Herb -- Herbert R.
