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,

As far as I know, the original Altair 8800 uses the normal full bat handle
switches. The Altair 8800a and 8800b use flat bat handled switches as
shown on mine here:

I had to find some of the flat bat handled switches and the auth
Oh duh for me! Confusion reigns supreme.
Yes.. the IMSAI uses those really wide plastic paddle switches.. that I had
always assumed were a +Carling+ part, as Carling has a line of switches
with similar handles.
Altair 8800A and B both use the metal mini-toggles - the former, bat-handle
the latter

The "B" model used a flatted bat handle toggle switch which IIRC weren't made
by C&K. I think I may have the number somewhere but I think there was a thread
with this info a few years ago. A Google search might produce it. The Altair
group archive on Yahoo might have it too.
The IMSAI uses a
"Not exactly--momentary, yes, but clearly not the paddle switches used on
the IMSAI. Fortunately, PCB-mount toggle switches are quite a bit
easier to locate."
Right, I thought about that once I'd posted.
My 8800A (with B supplies) still has the basic mini bat-handle style
switches. Correct me o

I got good ON-OFF address/data ones from Herb Johnson, but the momentary
ON-OFF-ON ones I have are worn out and do not return to center properly.

Not exactly--momentary, yes, but clearly not the paddle switch
Am I correct that the Altair 8800(A/B) also uses those type of switch?
If so, I need one or two as well.. my own, lone 8800 isn't quite what it
could be, IIRC. Had to sub switches.

Just FYI, technically those are known as MOM-OFF-MOM.
Hi,
Does anyone have any available? I don't need the paddles, just the
the ON-OFF-ON momentary switches.

ON-OFF-ON ones I have are worn out and do not return to center properly.
