What you have is silver reed dome with slider. They are really nice as far as domes go, I like them a lot.

Anyone know what this is? It looks like a sort of dome with slider, but not sure. I don't have the keyboard yet so can't comment on feel or sound. Thanks.

It is an wiki/Alps_dome_with_slider
Judging by the key above the numpad it is an AppleDesign keyboard.

I found a "Fountain" branded board and have not really found much information. Could anyone identify this switch? Seems similar to Futaba MA but not exactly.

Oh, cheers! I think it's the same maker (I suspect Copam), but a NOS model K-425 instead. (without the Elonex branding).
It's also a space saving model:

(annoyingly, while I don't hate the switches, a related Copam model K-430 had Blue Alps. Yeah.)

Going through old threads - Chyros identifies an identical looking switch as a "Copam foam and foil". I'd say that's a good bet.
viewtopic.php?p=430845#p430845

(although I wonder if he misspoke? He did a review of the Copam K-450 and there he calls it "Copam spring over membrane". And he does NOT like it, it even go a WANING. Which..odd, I find it an ok switch.)

Hi
Can someone please identify this Alps clone? It's in a PGA keyboard. Thanks.

Not sure clone switches can be identified without seeing the internal parts. But the mold markings look like Alps.tw 0A2:

The inside of the slider doesn't match up.

That's because a keycap stem is broken off in it.

Hopefully because you haven't had that happen personally. Not fun to have to dig them out, but I suppose there are worse things.

Kinda looks like Olivetti Typewriter module, Praxis maybe. If it is Olivetti it's most likely dome with slider, but thats just a guess.

Got a hold of an Olivetti keypad for one of their calculators from the 1970's or 80's. I think it's for a Logos but the styling is also similar on many Divisumma and Underwood models as well. It's linear with an external coil spring and a shorter throw than Alps SKCM/SKCL or Cherry MX switches about 2.5mm. The PCB is labeled Japan Alps and the switches have their own PCB's that are slotted through the main PCB and soldered to it.

Doing a search on the PCB code got me this page: https://telcontar.net/KBK/Alps/model_numbers

They list the switch under code SCH as "Spring Bridge" and has a link to pictures of the same switch from an Olympia calculator: https://imgur.com/gallery/IMTsl

Overall it's a pretty good feeling linear switch.

I just made a post about these actually:
viewtopic.php?f=62&t=25106

With yours having alps branding on the PCB itself and the additional info you linked it looks like they might be SSCH? considering the 3 letter code it lists for SKCC is just KCC. (It also looks like early ALPSavers may have had this switch at some point so that is cool although I doubt they were actually produced before the SSCH/SKCC switch)

Was going to suggest starting an page on the wiki for this but I just noticed that you've started one up. I've gotten interested in these Olivetti calculators so I might grab a few more of them.

some of the olivettis have SKCC cream in them so try to verify the manufacture date if you can (or at least get a model from an earlier line), pre '79 should be good for SSCH and after that should be SKCC if the pattern holds true. If you get SKCC older than 79 that'll be pretty significant as the oldest I am aware of for SKCC is '79.

Hi. I've seen this on sale and looks like a keyboard that I had when I was a kid. Do you know what kind of switches are these? Looks like Cherry Mx but I'm not sure. Keyboard company is Sunshine.
