Author(s): The Ultimate Guide to Mechanical Keyboards: Which switch is right for you?
Most run-of-the-mill keyboards are rubber-domed, a simple and inexpensive design where the key hits a raised bump and squishes it down (you’ll feel the slight squishiness when you type) to register a keystroke. Here’s the problem: rubber-domed keyboards require a complete depress, or bottoming out, to register. That extra effort over an entire workday can lead to hand fatigue, or worse.
Even though mechanical keyboards tend to cost a bit more, their build quality is worth it. Rather than lay down some cheap membrane layers and rubber-domed keys, these bad boys sport heavy-duty switches and functional parts. This makes them durable, and it also gives them tactile feedback that detects a keystroke before the key bottoms out. That means that with a little practice, your fingers are doing only half the work, sparing them a world of hurt.
