It is true that Kailh (Kaihua Electronics) is one of the manufacturers of the Razer Green switch, but Razer has them made to its own specifications.
They specified very little beyond their logo by all accounts I've seen...but lets go on and see what you have.
That is to say, they are not identical to any Kailh switch.
The force/displacement characteristic of the switch may be different, but the rest of the switch is Kailh.
The Razer Green switches even run on different production lines than Kailh switches.
If Razer switches have their own characteristic, then the switch stems are different, so there would have to be a separate tool for making the stems. This kind of investment is something feasible for Razer's bottom line, probably in the 10-30k range. However, when it comes to assembly of a part like this, you need a multi-part sorter and robot. We're talking $150k starting in China. Also, the same factory floor, same engineers, and same calibration equipment as used on Kailh stock switches are also going to be used on Razer switches. So, the output likely has very little different quality-wise from stock Kailh switches.
Further, Kailh is not the only manufacturer to produce the Razer Green switch. Razer will not divulge who any other manufacturing partners are, but Kaihua Electronics is not the sole supplier.
This type of defense is the epitomy of Min-Liang Tan side-show-social-marketing. Anyone who doubts me can follow his facebook feed or twitter to see these kind verbal deflections/misdirections/untruths that occur almost weekly as a response to someone complaining about Razer's products failing. The fact is that when these switches were released, the switch housing had a Kaihua logo on them (not sure if current runs do still). It would be incredibly cost prohibitive considering the size of the mechanical keyboard market for a company (crazy Razer included) to go to another factory and ask them to re-engineer the same switch, make entirely new tooling, buy new assembly robots, new testing robots, all to knock off an Cherry MX knockoff. At the $0.10 to $0.15 per switch that Razer is buying the switches from Kaihua for, the savings just isn't there to support such a huge investment and risk of failure.
In my conversations with various Razer employees, I was struck by how intensely they manage the switch making and quality assurance process
Your list is standard factory floor process, it's like keeping a car running, so no surprise there -- to say otherwise would require a comparison between other switch manufacturers. Don't be so "impressed" so fast.
To ensure quality, the switches are inspected by hand as they come off the production line, and then Razer staff further sorts the batches of switches as an additional check.
Razer has their own factory now? More like Kaihua has employees that Razer or you is calling "theirs."
Although we hoped to use the height gauge to measure multiple switches on actual keyboards, Razer advised us against it, as that use case is outside of the scope of what the machine is designed to accurately measure.
Bait and switch. They thought you wouldn't want to try? This makes no sense. Who has the proper test equipment? Why not use that?
Note that these tests were performed on two switches total. Therefore, these findings can be extrapolated only if we assume that the manufacturing consistency from switch-to-switch is precise, and as we've already discussed, there's a great deal of tolerance in the pretravel.
Statistics do not work that way. Testing one switch cannot be extrapolated, it can only be compared to a written spec.
The echo chamber is far too prevalent when it comes to knowledge about mechanical keyboard switches, and a common myth is that Razer's switches are just Kailh rebrands.
You're part of it. And just a Razer mouthpiece by all accounts I've seen here.
