Where does it say オムロン　株式会社?

I have the information I need now (added to the wiki already).

Same model number as this:

I'm more intrigued by the pale yellow switches. They're not the expected cream colour, nor the yellow colour you see sometimes. Since some don't work, we have greater odds of seeing what's inside of them.

Same mistake everyone seems to make: to believe that they have nothing to contribute. And there it sits.

What model is this? Maybe the service manual lists the Cherry part numbers.

It would take time to provide a carefully-considered path for you, but somehow it would inevitably involve improving the wiki's completeness and comprehensiveness. That is always my primary goal for the community.

If you ask me such questions, you will not like the answers I give ;-)

Not switches for typing, but switches for sensing — note that they're not in a PCB, but rather, attached to wires.

I could probably translate it but I unfortunately don't have the time at the moment. That was really useful information. You're on a roll lately. With SPARC's help, I've managed to transcribe the applicant: 立石電機株式会社 — Tateishi Electric Co., Ltd. (Omron's old name). He also found out that the invent...

Those unfortunately won't be MX-compatible, as they are M9 switches, not MX. M9 has at least two keycap mounts: MX and non-MX. These use a non-MX mount. I'm not clear on the specifics, but the MX-like mounts appeared to be for the short keycaps — it seems to have been all about short vs tall keycap...

Patents are a whole vortex unto themselves — was the product patented at all, has the record been digitised yet, has the record been given English metadata that I can search for (that mystery patent doesn't even have an applicant — I found it as it was linked from another patent) … and finally, what...

PCB inscriptions offer a lot of interesting clues, but they also contain a lot of more generic information that's hard to follow. CPC-77 94V-0: https://deskthority.net/w/images/thumb/9/91/Kroy190-PCB-Label.JPG/1280px-Kroy190-PCB-Label.JPG "94V-0" means UL 94 V-0: "burning stops within 10 seconds on ...

This patent has no inventor or applicant: https://worldwide.espacenet.com/publicationDetails/biblio?CC=JP&NR=H01109148U&KC=U&FT=D# It just bears a very strong semblance to the switchplate of [wiki]Omron Alps-style switch[/wiki]. I managed to find the patent on the Japanese patent website but they of...

I'm calling these [wiki]Philips torsion spring[/wiki] for now, since they're very close to a Philips patent.

Contact material and structure is not well known. Gold plating was more common, but some types used gold inlay. (Examples found to date are listed under [wiki]metal contact switch[/wiki]; like all the similar pages, it still needs a lot of detail adding.) Cherry however used a horizontally split pri...

Only 1 part gold in 30? I did wonder, but my guessing is not good enough: someone must know for certain. So that would make M84x (the last) more gold. The first two (M81x and M82x) have prism contacts, while the last one has cylindrical crossbar, the same as MX switches. Some years ago (mid 2000s, I...

Depending on model, Cherry M8 switch contacts used one of the following alloys for the upper block of each contact prism: AuAg 26 Ni 3 AgPd 30 AuAg 10 I can't find anywhere that explains what these mean. Not the elements (those, I recognise), just the composition notation. (For example, why is "AuAg...

Here is the patent for the fat Alps keyboard: https://patents.google.com/patent/US4906117A

What we know for certain: 1981: The patent applicant was Philips Electronics, and the inventor was Laurence Finlayson, whose address was given as c/o Pye Electro-Devices. 1983: Pye Electro-Devices is renamed PED 1984: These switches are used in the BBC Micro 19__: A parts catalogue lists the space b...

I'm surprised that I forgot about Cindy, as she's far from forgettable …

I remember it from the RM Nimbus. Are you saying that Philips commissioned the design from Mitsumi originally, and permitted Mitsumi to sell the design to other customers?

That would be "PET" not "Pet" though. Refund refused.

Are we ever likely to get the series name/part number(s) of the [wiki]Philips keyswitch[/wiki]? We are one step closer. I found the patent on Espacenet (while trying to find a patent for the switches in the Loewe keyboard), where there is more detail. Laurence Finlayson, the inventor, was working a...

Those are likely not RMD 973 (similar, but not the same). We don't know what they are. Loewe also used Cherry MX, but not with those exact keycaps (especially not with corner LED windows). Do you have any similar keyboard in mind? There are two similar switches, Ericsson RMD 973 (for which I found ...

You were walking in town, and he stalked you, tracked you down and pushed it in your face? :P

Oh, so you visited his house and photographed it, but did not buy it?

I just noticed something — that PCB was made by Wong's Electronics of Hong Kong.

These switches are damped, either with little damping prongs (something I've yet to photograph — my photography is just not sufficient to do justice to my collection of ~41 Clare/Pendar types, so that job remains pending) or with a rubber mat (as seen on the wiki under S880). This may be what gives ...

Oh, sorry, the second one I meant. The one that is obviously SKBM …
