A mechanical keyboard has a physical switch underneath each key, providing a different experience than the standard rubber membrane keyboards that come with most computers. These switches have a hard plastic stem with two metal contacts on the bottom that register when pressed by a key, sending signals to your computer that tell it what key you pressed and what function you’re pressing. The resulting feel is appreciated by many typists and gamers for its speed and tactile feedback.

Besides the basic form and connection type of the switches, what separates one keyboard from another are the options for key layout and extra features. Most modern boards are based on the Cherry MX switch mount, and there’s an immense amount of variety within that realm. For example, you’ll have choices in terms of keycaps and their mounting method; SA (Square Around) keys have a sculpted shape down the rows while DSA (Square Down) have a straight top with no sculpting.

You’ll also have to decide if you want to use ANSI or ISO keycaps. ANSI keys have a straighter enter key that takes up one row of height, while ISO keys have an angular entry key that takes up two rows of height. Lastly, you’ll have choices in terms of spring weight, which determines how forcefully each key can be pressed. Heavier weights are preferred by some typists, while lighter weights can help prevent keys from accidentally being actuated in reaction-based games. mechanical keyboard
