Frequently asked
Is the Chaosera Klein a heavy switch?
No — it sits in the medium range. Actuation lands around 48g with a 55g bottom-out, so it feels substantial without being fatiguing for long typing sessions.
Does the Chaosera Klein need lubing?
The PA12 bottom housing is factory-treated with PTFE and MoS2, so it already runs smooth out of the box. A light hand-lube on the springs and stem rails will refine it further, but it's not strictly necessary.
Will the Chaosera Klein work in a hot-swap board?
Yes. It's an MX-style 5-pin switch, so it drops into both 5-pin and 3-pin hot-swap sockets and solder PCBs.
