Built 2 versions of the MX/KS hybrid zilpzalp, here’s aome height comparison when using bottom plates. It may be possible to use shorter stand-offs, but going 1mm shorter, stuff started touching the bottom plate so i left it like this.
Bonus top view:
Interesting! Have you found any caps that fit well? I assume without the switch plate, you need to use soldiered switches, or does hot-swap work?
Not entirely sure about the hotswap option as I haven’t tried it myself. The footprint is apparently the same as for the KS-27 switches, and there are special KS-27 compatible sockets you can get from AliExpress.
I would also assume that soldering is needed without the plate since it’s a 3-pin switch.
Since Nuphy is selling boards with these switches, I believe their own caps fit them :)
