Title: Can anyone ID these switches?
Post by: Howie on Tue, 08 March 2011, 11:51:56
Hello there, this is my first post. Been lurking for a while, and then finally decided to join up. Sorry if this is posted in the wrong place or something.
Anyway, on to my question.

While wating for EK to get Leopolds with ISO layouts out, I remembered this old keyboard we had laying around. I believe it came with my dad's first computer. I figured if i can get ahold of a converter here in Norway I might just try hooking it up to my pc.

Now, I have no Idea what kind of switches these are. Is there anyone who has a clue? The keys are linear, and i forogot to take a pic of this, but inside each keycap there is a spring, that connects to the keycaps and the switch itself. The brand is Multitech.
Some photos:

Pretty dirty. I guess it has gone for like 20-25 years without being cleaned. Maybe I should try shining it up a little.
(and yeah, that space bar is enormous)

I'm no master photographer, but i guess these do the job.
Looked through a whole bunch of wikis and stuff, and I've never seen this type of switch before.
Thanks for any help :)

I was thinking of some early Keytronic switches, something like an earlier generation of these: http://sandy55.fc2web.com/keyboard/kt_e03418.html

I think it would be better if you took a picture of any identifying stickers on the keyboard, especially those on the back or inside of the case.

Alright, got a couple more shots. These are all the stickers on the board.

And without the front part of the case on:

Pics kinda don't show up?

Anyway, looks like a foam and foil capacitive from AT days. Good. Cleaning. Required. (Water and dish cleaner, or denture cleaning tabs for the keys.) DIN plug, I guess? An adapter to PS/2 should sort that out.

Hmm, Don't actually don't know what happened to the pictures. I'll try to sort them out soon.
And yeah, DIN plug. Gonna try to find an adapter somewhere here in Norway. The keys actually feel really good, and I wouldn't mind giving it a try. Definitely needs a good clean though. I'll see what I can get done about it.

Thanks for the help!
