Mechanical numeric keypad with Cherry MX switch. Choose from a brown axle, silent axis or blue axis (camouflage only). The keystroke is approximately 4mm (3.7mm for Silent Red is 3.7mm) deeper than typical keyboards, and the contacts are approximately 2mm pressed down for extra movement. Therefore, there is no need to push down the key all the way down and prevents typing errors caused by a bottom error such as a membrane switch, making it easier to type faster. The shape of the case and the texture of the key top are also matching with each Majestouch series. In addition, it is compatible with USB-6 key rollovers, so there is no mess of input, and the detachable cable makes this a truly professional numeric keypad for mobility and desktop maneuverability.
