Why full nylon?
The switch market these days prospers with switches that come in different colors, materials, and travel distances. We are blessed with so many options, and with a little bit of effort and searching, almost everyone could find a switch that fits their tastes and preferences. That makes designing new switches a lot more difficult than it used to be because if we are not careful enough, our so called "new design" would stumble on an already existing design and become a re-color. That's why when we try to do it, we try to use new molds and new materials if possible. The goal is not only to create something that looks different on paper but also stands out in terms of sound and feel among most existing options. That is why we went with a full nylon design for the Keygeek PA switch.
Full nylon switches are very rare in the market for a few reasons; The surface friction coefficient tends to be high between switch parts made of the same material. This means if the nylon blend is not carefully treated, a full nylon switch will become super scratchy, and it's not a pleasant scratch. Furthermore, full nylon switches tend to sound pretty muted, or almost dead. To solve these issues, we did these things with Keygeek:
1. The top housing is made of a special nylon blend to increase smoothness. You won't feel scratch when using the PA switches as they are as smooth as it gets
2. To make the bottom out sound more pleasant, we went with a nylon blend called N5. It has fiberglass as an additive, and it makes the overall sound profile clackier, brighter, and poppier. In the meantime, the PA switches sound different from most clacky switches in the market as full nylon creates a more bassy and condensed sound.
Factory Lubing and Noise Control
Keygeek has been getting better and better at their factory lubing process and controlling unwanted noises coming from their switches. With the most recent updated mold sets, the PA switches sound very clean and feel very smooth out of the box. Some previous issues that existed with Keygeek switches, such as ticking noise and feeling oily and sticky no longer exist on recent Keygeek switches, and Keygeek PA among them.
Molding Changes:
Because different materials have different shrinkage rates, the stem mold made for POM or UPE couldn't be used to make Nylon stem. That's why Keygeek made this new stem mold.
