Matt3o has
reviewed the Cooler Master SK630 with Red switches.
He wrote that the MX keycaps he tested "worked just fine".
I have got a Cherry MXLP Speed Silver from a person who had attended a keyboard party in Germany where samples had been handed out. I have tested it with a multimeter, and a few different MX keycaps:
• Thin-walled keycaps actuate, with some margin, but the skirt will hit the plate when you bottom out.
• Thick-walled keycaps (ePBT, Cherry/GMK doubleshots etc.) actuate with some margin, but will bottom out against the switch's top housing because the switch does not become narrower near the top like Cherry MX.
BTW. A KiCAD footprint for DIY keyboards is available in
Keebio's repo. One pin position is almost identical to that of Kailh Choc, so I'd suggest making a combined footprint. Kailh Choc are available now but we don't know when the MXLP will be.
