As for "Cherry MX Yellow"

[UncleFan]

Hey, guys! Today I'd like to talking about ''Cherry MX Yellow''.Currently there is a lot of controversy about it.It seems that only Chinese players can solve the truth.As of today, I had collected a total of 4 kinds of ''cherry MX yellow switches'' and a ''cherry M8 yellow'' from ''G80-0978/0''. and also have 2 kinds of ''Hirose Cherry M8 Yellow''.

all of them

Let me introduce them first:
switch''A'' was from TaoBao: https://item.taobao.com/item.htm?spm=a1 ... 7319399100
switch''B'' was from TaoBao: https://item.taobao.com/item.htm?spm=a1 ... 6475149015
switch"C'' and ''D'' were from the same keyboard: https://item.taobao.com/item.htm?spm=a1 ... 1163807092
switch''E'' was the spacebar in ''G80-0978/0''.
switch''F" was the spacebar in "Panasonic VP-0187A''.
switch"G" was the spacebar in "Epson HC-20''.
"F" and "G" is the Hirose Cherry M8 switches, theyir craft are different with German craft.So we don't need to compare with them.
Now we can use "E" as a standard to compare them:

A B C D E

The most suspicious place of "Cherry MX Yellow'' is their key-stem.at first, I compare "A,B,C,D"'scolor.Unfortunately, none of them match the cherry color.

and there is a letter "C'' on the "A" key-stem,a letter "D'' on the "B" key-stem,a letter "F'' on the "C" key-stem,a letter "D'' on the "D" key-stem

This is the most questionable,I had collected many cherry switches,none of their keystem has a letter. The letters are replaced by numbers in cherry switches.Here are the others photos:

Note that this is the best evidence that it is a counterfeit product, the bottom shell of "A and B" hasn't serial number. Although C and D have serial number.But they may have changed the shell.
In China, the history of CHERRY MX Yellow switches dates back 8 years. According to my survey, It first appeared in the KBC forum,They are the closest switches to the cherry craft.There are many differences with my MX yellow switches.It is said that they are customized.

But the KBC forum is closed,I can not get more information. By the way, BroDragon's MX yellow switch was also from KBC.
As for these yellow switches, BroDragon had introduced them in the China Forum:

Other records of the MX yellow switches:

Please note this photo, It is like a fake product.

At the moment, KBC's yellow switches are the most real,I've been trying to find them, but I did not find it.If the DT Forum has former KBC members, hope you can contact me when you see this theme.I hope to get more information.

According to Cherry in Germany, the letter on the stem shows that it is a fake part. So A, B, C and D all have fake stems

The switch tops look real.

Switch bottoms A and B (with no diode symbol or mould number) do look suspicious. Cherry shells without fixing pins also have circles where the fixing pins go, suggesting possibly that the same mould can do either. Those are also notably absent.

By the way, why would a tire factory have old keyboards? Did you mean electronics recycling centre?

Lol thought that was weird too so had a look. 轮胎加工厂 is the text which apparently means 'Tire processing plant'. I'm guessing they process other rubbish too. If you keep flicking between English and Chinese in ElGoog, it does eventually turn into 'Tire factory'. Maybe people think the keyboards have *rubber* domes in them

Uh...The original is "tire factory".I also don't understand why...
Now I'm sure all of my "MX yellow" is fake.
Those MX yellow from KBC looks like real cherry products. There are many differences with my MX yellow switches.

Here's my question: what was the goal of making yellow MX switches? What did anyone hope to achieve?

Maybe getting rid of excess yellow plastic pellets in the storage that would go to waste else maybe... or a wrong order/shipment of a charge of pellets. (As they all have sligthly different yellow color maybe it got mixed with the next charge of plastic in the correct (clear?) color over time.
