There’s a tool that we use everyday without even thinking about it. It’s the tool of writers, bankers, scientists, and thinkers all over the world. It’s the humble keyboard, and there has been a major improvement in its design. Traditional keyboards use rubber domes to register key presses. This design is cheap to manufacture, but it isn’t very good, and here’s why. Rubber dome keyboards require you to fully depress the key to register a keystroke. Not so with mechanical switches. Mechanical switches typically have a range of motion of about 4mm, with the actuation point being at 2mm. This gives you 2mm of extra space before you bottom out the key. Less distance between the key and the actuation point means you use less force when typing, and put less stress on your hands. Another advantage of mechanical switches is that they feel better to type on than traditional keyboards. Mechanical switches feel crisp and precise, while traditional keyboards feel mushy and inaccurate by comparison.
