The world of mechanical keyboards remains niche, but one of the more well-known names has shuffled its lineup ever so slightly. The Das Keyboard Quiet, with Cherry MX Red switches, is now available for purchase. The model has been known for a while, being mentioned on the official Facebook page months ago.
Externally, the Quiet model looks identical to the Professional model, with the marked keycaps. There does not appear to be an unmarked variant. Over on the official website, the choice of switches for the Professional seems to have disappeared. They can still be bought through another page on the site, but it might suggest further reshuffling is on the way.
The Red switches are the lightest official Cherry switch, actuating at around 45cN of force. They are "linear" and make no click with no tactile bump; defining features of the other switches offered. Interestingly, the Das website makes reference to the Red switches being tactile.
Back in 2012, Tim Schiesser looked at the Corsair K90 (with Red switches), while I reviewed the Das Keyboard. Between these two reviews, you should be able to get an idea of the Quiet models offerings. Theres also an interview with Das Keyboards CEO, courtesy of TechCrunch.
