Because when they say Cherry Red, Blue, Brown, etc... Cherry is the Key designer. If they just refer to MX switches then they are a generic or Company made. Roccat for example makes their own Mechanical MX switch. Corsain on the other hand is buying it from the company that makes the best switch aka Cherry. As for The QA and Manufacturing process that was a guess. For all I know it could be a interface issue with a Corsair part or the Panasonic part or the software.
