[IC]Still this pure blue."Klein R2"

[CHAOSERA]

After a year, Klein Switch R2 is reopened after a modified mold. As a main smooth shaft, the shaft still continues to use P3 material.

P3 material: P3 material is named internally by JWK, in fact, this material is a newly developed hybrid material, which is composed of a mixture of materials. Compared with the traditional POM, PA66, PC, etc., it has better smoothness, lower coefficient of dynamic and static friction. It also has more excellent self-lubricating properties, and its main component materials are known as "solid lubricant".

Because of its excellent self-lubrication, P3 has a lower coefficient of friction with other materials, such as POM, than with other materials.

Friction coefficient between P3 and PC material = 0.07
Friction coefficient of P3 and 7035 copper material = 0.09
Friction coefficient of P3 and PA66 = 0.06

The above is the coefficient of friction between P3 material and other materials, below I will list the coefficient of friction between POM and other materials.

friction coefficient between POM and other materials.

Friction coefficient of POM and PC material = 0.42
Friction coefficient of POM and 7035 copper material = 0.36
Friction coefficient of POM and PA66: 0.38

It can be found that the friction coefficient of P3 material can be 4-6 times better than that of POM, which is the main reason why Klein Switches is particularly smooth.
In response to the market feedback of Klein Switch R1, after opening the cover, the upper cover will have loose phenomenon, re-optimized the mold, the upper cover tighter, R2 has no need to add the switch pad, different from R1 and R2, the new version of the upper cover added our LOGO, Just like in following chart

At the same time, is also received market feedback. r2 spring increased by 2mm. rebound becomes more powerful. Therefore, it is no need to change the spring.

Additional

As a JWK OEM high-end switch, it will be well lubricated. Especially because of the re-modified mold, the noise control will be better than before. But JWK factory lubrication as we all know, spring and leave sound is not guaranteed. If you are a user with high requirements for sound, we recommend re-lubricating these parts.

there really don't have to be ics for jwk recolours especially when other people are already selling them

I see another long pole linear and my eyes glaze over.

Thank you for your reply. Since the switch was sold last year, the evaluation of its smoothness has always been good.
This time we have re-modified the mold, and its stability is much better than before. There is no need for a switch pad at all.
With the addition of some minor adjustments, compared to the Klein R1, the smoothness has been further improved, so I want to share it with you.

Thanks for sharing was hoping be able to snag some of these. Do you know who may be a North American Vendor?

divinikey is coming soon

I see another long pole linear and my eyes glaze over.

Which long pole linear, compared with the general long pole, we will pay more attention to smoothness
