Welcome to White Rabbit Japan!
The Happy Hacking Keyboard Professional 2 is a favorite keyboard among coders and UNIX system administrators because of its size and the superior engineering of the keystroke (45g of pressure, 4mm stroke) described as having a crisp touch, smooth fit and gentle change in load . The small size reduces wrist movement, improving typing efficiency and reducing fatigue, and also making it very portable for those who travel frequently.
By detecting a change in capacitance value due to depression of the conical spring, they keyboard registers the keystroke without contact with the electrode, further reducing fatigue. Even the sound emitted when typing is designed to be environmentally friendly (2,500 – 5,000 Hz).
The keyboard layout can be switched between Mac and PC modes
