The base of any proper board is the key switches, and this version of the Code comes loaded with your choice of Cherry MX Brown, Cherry MX Green switches, or MX Clear switches. Clear switches are one of the rarest varieties of switches, and are often described as "stiffer Cherry MX Browns." They are the favored switch of programmers and office workers, since they provide an incredible typing experience, aren't incredibly loud, and have increased resistance after their actuation point to prevent bottoming out. The Greens boast the actuation force of IBM spring switches with the tactile click that can be found on the Cherry MX Blue switch. The next layer features white LED backlighting—available in seven brightness levels—to illuminate your ABS plastic keys. The legends themselves were printed in classic Helvetica. If you’re key-mashing, you’re good for six-key rollover using USB interface, or N-key rollover with PS/2.
