Hey guys, I was wonder if I can replace the blue switches for the brown switches, so i wrote an email for QWERkeys and they sent me this picture about the models.

Does anybody know what part number exactly "fits" in this keyboard?
Edit: Well, according to DeskthorityWiki:
- MX1A-xyNN no diode, plate mount (no fixing pins)
- MX1A-xyDN with diode, plate mount (no fixing pins)
- MX1A-xyNW no diode, PCB mount (with fixing pins)
- MX1A-xyDW with diode, PCB mount (with fixing pins)
Okay it's plate mounted. Now I need to know, with or without diode? What's the difference?
