Getting to know the different types of mechanical keyboard switches is key to creating your perfect typing experience when customizing a keyboard.

Mechanical keyboard switches are the heart and soul of your keyboard. They are the mechanisms under each keycap that dictate the precision, responsiveness, sound, and feel of your keystrokes. Choosing the best switch for your keyboard requires some understanding of the different types of mechanical switches, their unique characteristics, and their pros and cons for various uses.

This guide aims to help you make an informed decision when customizing a keyboard, whether it's your first time diving into the world of keyboards or you're a seasoned enthusiast. We will delve into the most popular types of mechanical keyboard switches, their characteristics and best uses, where to purchase them, and any compatibility issues you may need to consider.

Mechanical keyboard switches are tiny components consisting of a top housing, a bottom housing, a stem that mounts the keycap and moves with each press, and metal contacts that register the keypress. These components determine factors like pre-travel and total travel distance, actuation force, tactile bump, reset point, and more. Simply put, the switch under a keycap dictates the keystroke's sound, physical feedback, and actuation point.

When choosing keyboard switches, most people consider the typing sound and feel. These characteristics are crucial not only for your comfort and satisfaction but also for your typing speed and accuracy, which depend on your personal preferences. The distinctions between different switches are important whether you’re using your keyboard for work, gaming, or general purposes.

Key switches, along with keycaps, are the defining features distinguishing mechanical keyboards from rubber dome keyboards, which are often bundled with pre-built desktops or sold as budget accessories. It's essential to understand at least the three most common mechanical keyboard switch types: Linear, Tactile, and Clicky. Major switch manufacturers often color-code them as Red (Linear), Blue (Clicky), and Brown (Tactile), though this is not a universal standard.

Regarding compatibility, most switches available in the market are "Mechanical X-Point" or MX-style switches, first introduced by German manufacturer Cherry in the 1980s. While Cherry itself sells full keyboard sets, many other manufacturers use Cherry switches or MX-style variants, such as Gateron and Kailh switches. Some less common switch types do exist, so it's wise to confirm a keyboard's specifications before making a purchase.

Linear Mechanical Keyboard Switches

Linear mechanical switches offer a smooth and consistent keystroke throughout the actuation process. Unlike Tactile and Clicky types, Linear switches do not produce any bump or clicking sound before actuation, leaving you to feel the keycap and the resistance of the spring alone. This mechanism allows the switch stem to move freely without interruptions.

Because there’s nothing to impede finger movement, Linear switches are generally the fastest for typing. Thus, competitive gamers who rely on custom keyboards often prefer Linear switches as the saved milliseconds can be invaluable in fast-paced games. They are also typically the quietest among the three major switch types, making them a good choice if you share a space and don’t want to disturb others.

One downside of Linear switches is their sensitivity, which can lead to accidental keystrokes. This may affect your work efficiency while getting used to a new keyboard. Additionally, some people find themselves bottoming out the keys more frequently, which can contribute to finger fatigue and quicker wear on the switches.

Clicky Mechanical Keyboard Switches

While Linear switches are light, responsive, and quiet, Clicky switches are heavier and more tactile, producing a significant auditory click with each key press. The mechanism of Clicky switches involves tactile feedback that you must overcome to register a keystroke, accompanied by a loud click to indicate successful actuation. This can be particularly useful for those who prioritize accuracy while typing.

The click and tactile bump also make it easier to avoid bottoming out, reducing finger strain and wear on the switches. For enthusiasts seeking the ultimate typing sound, Clicky switches provide the loud and satisfying clicks they desire.

However, the loud clicks can be disruptive to others, making Clicky switches a less ideal choice in shared environments like offices or homes where someone may be trying to concentrate or sleep. Their tactile resistance and click noise also make them less suitable for gaming.

Tactile Mechanical Keyboard Switches

Tactile switches are often viewed as the middle ground between Linear and Clicky switches, providing a tactile bump similar to Clicky switches but with a much quieter sound. While not typically as quiet as Linear switches, Tactile switches are preferred by those who want feedback without the loud click.

Tactile switches are versatile, making them suitable for a variety of uses, from working and gaming to leisure typing. However, their adaptability means they may not excel in any specific function, lacking the speed of Linear switches for competitive gaming and the pronounced feedback of Clicky switches that some professional typists might prefer.

While the aforementioned are the most common switch types, they are not the only ones you need to be aware of. Always check for keyboard compatibility when exploring other switch types:

• Low-Profile: These switches use a similar mechanism to most market switches but have a shorter design for reduced travel distance and a more minimalist aesthetic.
• Optical: Instead of physical switches, optical switches utilize infrared light to register key presses, offering potentially faster actuation.
• Hybrid: Combining elements of rubber dome keyboards and mechanical switches, hybrid switches offer a mix of actuation and tactile feedback.
• Electrostatic Capacitive: These switches, such as Topre switches, offer precise actuation points with satisfying tactile feedback. The Type-S variants are even quieter without compromising feel.

Armed with this guide, you should now have all the information you need to equip your mechanical keyboard with switches tailored to your desired sound and feel.
