That's an interesting item. What type of switch would this be?

Weird, that's what. The inner spring looks about the same diameter as a space invader's, while the outer one looks more like a Topre's space bar.

Bad news though: the keyboard has some old computer glommed under it:

Could that be the cryptic spring-over-dome-under-slider-inside-spring-under-cap switch???
On a serious note, it seems to have a terminal embedded!

[andrewjoy]

a terminal ( am am making the jump that its a serial terminal), built into a keyboard that is very very cool.

The itch is great to grab it but with mail forwarding & stuff it will end up over 100$ to Romania considering the weight.

That's an interesting item. What type of switch would this be?]

Quite a few switches applied pressure to the membrane using a coil spring, including at least one Alps design. A couple of examples:

[wiki]Oriental Tech spring-over-membrane[/wiki]
[wiki]Alps spring over membrane[/wiki] (better pictures on [wiki]Oriental Tech OK-100 series[/wiki])

Acer semi-mechanical switches have a little plastic arm in between the spring and the membrane, but often the membrane pressure spring is bare like that. In the linear designs, you have a small inner spring that presses on the membrane, and an outer spring that pushes the key back up.

I don't know what that specific switch is. The black part just seems to be a slider shaft that snaps into some sort of plate. I can't make out the out-of-focus part.

Cross Alps

Note those Bulgarian sellers somehow decided that “Alps” means slider, and have listed all kinds of stuff as “Alps” that has nothing to do with Alps switches.

Anyone knows if this is rubberdome or foam and foil?

It's in very good shape though. Most of the used ones I've seen, including my own, are awfully yellowed (casing and space bar, the other keys are PBT). I don't remember how thick the key caps are, have to take a look when I'm at home.

[andrewjoy]

i am still temped the lettering is lovely and if i am ever lucky enough to find a board with green alps in it would be a good candidate for a retrofit. i have just never seen an alps with decently thick caps

[Nuum]

Judging from Ripster's photos here, I'd say they are decently thick.

[andrewjoy]

gah i am very tempted now !

[mr_a500]

Have you seen what the keycaps look like on an M0115?

[Muirium]

I have one of each on its way from Cindy, along with a 3276 beamspring, incidentally…

Well, the second one.

It is refreshing to see that you finally got a bargain on a great keyboard on your side of the Atlantic!

[Muirium]

Nope. Texas! I'm yet to get it over here.

With Windows keys, most likely rubber dome over membrane.

Thanks. I was about to buy it with another offer just to check. But for a rubberdome it would be to much.

Somebody just won the Philips keyboard (Prah Commander) ebay action ...

Does anybody know what switch is this after all?

[Daniel Beardsmore]

Preh, not Prah.

It's similar to this one, which is a rubber dome:

http://deskthority.net/f-o-r-s-a-l-e-f5 ... t6039.html

Some rubber dome keyboards (including Topre) have discrete slider guide shafts that snap into a plate (metal or plastic), but unlike microswitches, they're open at the bottom just as with Acer switches. That's what these appear to be. Topre do it because they have a metal plate; most keyboards simply mould the guide shafts directly into the lid of the keyboard itself — harder to mould, but far less assembly effort.

Jacobolus & Daniel, thanks for information/correction.
So Preh, not Prah, not Alps, and certainly not ... To-preh
They seem to me to have discrete slider guide shafts, not moulded.
