Mitsumi has been around for a very long time.

They have made many cheap keyboards for IBM-compatible PCs. The vast majority of the keyboards that were built into Commodore Amiga computers were made by Mitsumi. A variant of Apple Extended Keyboard II has innards made by Mitsumi.

These catalogue you link to contain not keyboard switches, but tiny switches intended to be put into small devices, such as cell phones.

What switches do their keyboards use?

Unfortunately a really big mix of interesting and cool (i.e. I want) or crappy domes and everything in between.

AFAIK, Mitsumi keyboards have included switches made by the same company.
None of the mechanical Mitsumi switches that I have tried have been very special ... but then I have not tried that many. Amigas (spring and conductive rubber) and PCs (rubber dome), basically.

What kind of Mitsumi switches did you find interesting, and in what way?

I'm guessing he ran across them because someone at OCN made a thread about wanting to upgrade from their mechanical Mitsumi board.

I found the PDF on the keyboard. Sounds like some sort of tactile rubber dome.

I've seen many of those Mitsumi keyboards on ebay

Findecanor · 02 Jul 2011, 20:36

That type is very common. I think Mitsumis keyboard for Amiga computers used precisely the same mechanism, only that many of them had coiled springs instead of rubber rings.

Oh I just saw one of those at goodwill it attracted me to it right away but I did not purchase it.
