These ship with BOX Jellyfish linears; a good choice for an RGB board thanks to being all-clear. As a bonus, they're highly resistant to dust and even water (this resistance doesn't carry-over to the PCB though, keep that in mind).
The PCB is South-facing, though with these switches it doesn't really matter; the cylinder-shrouded BOX switches are direction-agnostic. That is, it doesn't matter what direction they're mounted in, they won't interfere with GMK or other typically North-interfering caps.
