The world's first luxury catalogue for mechanical switches, this book is like an encyclopedia of mech keys knowledge. In it are 52 full-color pages with loads of information on 12 of the most common switches on the market, including large illustrations, force curves, bottom-out forces, and much more. However, reading about each switch isn’t enough to understand it, which is why the booklet includes everything you need to assemble your own switch tester, too. Complete with all 12 switches described in the book, the tester helps you get up close and personal with the sound and feel of each switch before you take the plunge on a whole-new keyboard.
