Unidentified Vintage Switch

[jevvix]

Was doing my monthly thrift store rounds and came across this electronic adding device. At first I thought it was some sort of rubber dome, but they are clearly individual switches mounted on a plate with a PCB underneath. They were completely linear and smooth as butter. Super thick double shot key caps - almost completely solid. Didn't have much luck getting an ID from the DT wiki so does anyone have an idea?

It was $5 so I didn't buy it but I snapped a picture of it:

Not sure, but whatever it is those keycaps are incredible.

Kinda looks like they will fit on a Topre

Topre stems have 2 nubs on the sides, this board's stems only have one. The stems themselves also seem a bit tall for a Topre board. Would be neat though, I have seen reports of certain typewriter keys working with Topre stems.

$5!! Why don't buy it? I hope to buy it.
Which brand is it?

I didn't buy it because I got another one 

   

I am not sure which brand the first one was. I will go back and see if it's still there but it's at a thrift store quite out of the way. Hopefully it's still there.

Also picked this up. $8.26

Very nice. A Goodwill I happened to stop at recently had an Olivetti typewriter for $6. Didn't pick it up, but it was cool to see something with the original legends from a keycap set that is pretty well loved in this community.

Looks the same as the Brother typewriter stems that work with Topre.

The stem on the one pictured here looks wider than the one on the Brother keycaps, so they might not fit.

I love old counting machines, they have great caps. Found these on one about a month ago

Holy cow!  I didn't realize the keycaps on some of the calculators I have lying around would be great for the community.  I'll be sure to post them in the classifieds for free once I get a chance to move them.

I also have an entire Micros brand hotel property management cash register system with all the original keycaps.  I believe they're double-shot, but I don't know what the stem is like.  But I won't have time to get the caps off of it unless it's going to be worth my time.

But the Alps SKCC cream isn't rare than the first one...
I 'd like to see that big keycaps "+" inside the second keyboard. It's big and weird!

Looks very similar to the stems on the Apple M0110

LOVE the caps on that first adder, what was the brand?
