Tokyo Electron 1280-001345-11

Here's something I've been looking out for a really long time. A *keyboard* with Tokai MM9-3 switches!
Has a pretty interesting force curve.

Seems to be some sort of control panel made by Tokyo Electron. Tokyo Electron is a sort of VAR (Value Add Reseller) from what I've heard about them through my real job. I've seen all sorts of control panels by them on ebay (but they've always been stupid expensive...).

Seems like this thing was made in Japan, shipped to Israel, then shipped somewhere in the US, then shipped to me in California.

Wow, finally an actual keyboard with these in! I have some loose switches but had never heard of anything that actually used them.

These are the weirdest switched I've ever seen, by the way. Hall effect, magnetic valve and acoustic got nothing on this. I genuinely haven't a clue how these things work, even though I dissected two to see what was going on inside. It's absolutely baffling.

Good stuff. This switch has 2 clones(no TKC logo). I have all of them. One clone can buy at electronic shop today.
The interesting thing is all keyboard has it which made from China or Japan.
Desloder is the only way to determine it is clone or original MM9-2.
The [JP]RB-614C REMOTE BOX(MM9-2) also has it. I think it's not too hard to find but hard to find the difference on out looking.

Here's the original switch with TKC logo on the China teleprinter

These are MM9-2, not 3. MM9-3 and and MM9-4 are JIS C 2809 panel mount (wide legs with holes in them). The ones with regular PCB solder terminals are MM9-1 (6 mm keystem) and MM9-2 (4 mm keystem); yours are the latter.

(MouseFan claims to have MM9-1; it's hard to tell from his photos, but it does appear that they may have the taller 6 mm keystems after all.)
