Hi Everyone,
We are the customization lab
“CHAOSERA”.
In our last posting, we mentioned the
upcoming launch of a new linear switches produced by JWK OEM
Klein switch
This post will detail information about
the Klein switch and explain and publish information about
the special material P3 in it.
The specific materials
and parameters are as follows:
Upper cover: PC + other
trace materials
Lower shell: PA12 + 2 micron PTFE +
MoS2 + other trace materials
Trigger stroke:
2.0mm±0.3mm
Touch bottom stroke: 3.7mm±0.3mm
Trigger
pressure: 48g±10g
Touchdown pressure: 55g±10g
Spring:
Extended gold plated spring is used
Contact: Upgraded
to palladium alloy contact which is more advanced than gold,
to improve stability, durability and conductivity.
Axis:
P3
P3 material is named internally by JWK (JWICK), but
it is actually a new hybrid material developed by JWK, which
is a mixture of several expensive materials. Compared with
the traditional POM, PA66, PC, etc., it has better
smoothness, lower coefficient of dynamic and static
friction. It also has better self-lubrication, and its main
component is called “solid lubricant”.
Main materials:
UPE (Ultra High Molecular Weight Polyethylene)
Ultra
High Molecular Weight Polyethylene fiber composites have
been used in the military as the shells of armored weapons,
radar shields, helmets, etc.; in sporting goods, they have
been made into bowstrings, sleds and water skis.
The
UPE used in our switch is a higher quality UPE with
molecular weight higher than 150,000,0 produced by a
Japanese manufacturer, which has limited production
throughout the year, expensive and difficult to transport,
but we insist on using this material to achieve the best
results.
Auxiliary materials: POM, PA66
Friction
coefficient of trace material is PTFE and MoS2 P3 material
compared with other commonly used axle body materials by our
lab:
Coefficient of friction of P3 and PC material ±
0.07
Friction coefficient of P3 and 7035 copper ±
0.09
Friction coefficient of P3 and PA66 ± 0.06
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 P3 material compared to POM, which is often used as a
shaft material, is basically 4-6 times smoother than POM.

Aftermarket related:
In principle, only
after-sales utility damaged switches.
Since the shell
is high-gloss polished, inevitably caused by cuts in
transit, so small cuts are not given after-sales, if the
shell is damaged what can be after-sales (ex: The switch
terminal pin is damaged, depressed, The shell is
notched,).
