Mechanical keyboards have become a go-to choice for gamers, typists, and enthusiasts alike, thanks to their tactile feedback, customization options, and durability. But what exactly makes up a mechanical keyboard? In this blog, we’ll break down the essential components—switches, keycaps, PCB, and more—that work together to create the ultimate keyboard experience.
1. Mechanical Keyboard Switches: The Heart of Your Keyboard
The switch is arguably the most important part of a mechanical keyboard, as it determines the feel and performance. A mechanical switch consists of several key components:
- Stem: The part of the switch that moves up and down when you press a key.
- Housing: The outer casing that holds all the components in place.
- Spring: The spring inside the switch provides resistance, and its tension determines the actuation force.
- Contact Points: These allow electrical current to pass through when the key is pressed, registering the keystroke.
Types of Mechanical Switches:
- Linear Switches: Smooth and consistent with no tactile bump or audible click. Ideal for gaming, where speed and precision are key.
- Tactile Switches: These have a noticeable bump in the middle of the keystroke, providing tactile feedback. Great for typists who need more feedback with each keystroke.
- Clicky Switches: Similar to tactile switches but with an additional click sound. These are popular among those who enjoy auditory feedback while typing or gaming.
Each type of switch offers a different experience, and the choice between them comes down to personal preference.
2. Keycaps: The Interface Between You and Your Keyboard
Keycaps are the top part of the mechanical keyboard that you press. They come in various shapes, sizes, and materials, which can significantly impact the feel, sound, and appearance of your keyboard. Here’s what you need to know about keycaps:
- Material: Keycaps are generally made from ABS (Acrylonitrile Butadiene Styrene) or PBT (Polybutylene Terephthalate). ABS is lighter, but it wears out more quickly, while PBT is more durable and resistant to shine over time.
- Profile: The profile refers to the shape and height of the keycaps. Common profiles include OEM, Cherry, DSA, and SA. Each offers a different typing experience, with some being higher and more sculpted, while others are shorter and flatter.
- Legends: Keycap legends are the markings on each key, usually made with dye-sublimation or laser engraving. Dye-sublimation ensures the legends are durable, while laser engraving can wear down over time, especially on ABS keycaps.
Keycaps aren’t just about looks—they also impact typing comfort and sound, so choosing the right set is important.
3. PCB (Printed Circuit Board): The Backbone of Your Keyboard
The PCB is the foundation of a mechanical keyboard and houses all the electrical connections needed to register each keypress. The PCB sends signals to the computer whenever a key is pressed, ensuring each keystroke is accurately recorded. There are a few types of PCBs commonly used in mechanical keyboards:
- Hot-Swappable PCB: This type allows you to easily change switches without soldering, making it great for enthusiasts who want to experiment with different switches.
- Non-Hot-Swappable PCB: To change the switches on this PCB, you’ll need to desolder them. This offers more stability and often comes in premium models.
- Standard and Custom Layouts: PCBs come in different layouts, like Full-size, Tenkeyless (TKL), and 60% layouts, allowing you to choose the size and functionality that fits your needs.
In addition to the basic PCB, some keyboards include features like RGB lighting or programmable keys.
4. Case and Plate: Housing and Structure
While not as often discussed, the case and plate are essential components that support and protect the internals of your keyboard. They also affect the overall typing experience.
-
Case: The case holds everything together and gives the keyboard its shape. Cases come in various materials, such as plastic, aluminum, or steel, and each material impacts the keyboard's weight and sound. A solid, metal case typically produces a more satisfying sound profile than a plastic one.
-
Plate: The plate is the layer on top of the PCB where switches are mounted. Plates come in various materials, including steel, aluminum, brass, and polycarbonate, and each affects the keyboard's acoustics and feel. A metal plate, for example, will give your keyboard a more rigid and sturdy feel, while a polycarbonate plate tends to offer a softer and quieter typing experience.
5. Stabilizers: Ensuring Smoothness on Larger Keys
Stabilizers are the small components that stabilize larger keys like the spacebar, enter, and shift keys. These components ensure that the larger keys don’t wobble or feel inconsistent when pressed. There are two main types of stabilizers:
- Clip-in Stabilizers: These are easier to install but can feel less stable compared to screw-in stabilizers.
- Screw-in Stabilizers: These provide a more secure and stable feel but require more effort to install and mod.
Some enthusiasts mod their stabilizers for smoother keystrokes and quieter sounds.
6. Other Essential Components:
- Switch Lubing: Many keyboard enthusiasts lube their switches to improve smoothness and reduce noise. It’s a labor-intensive but rewarding process.
- Dampening Rings (O-rings): These rubber rings can be placed around the keycaps to soften the impact when you bottom out a key, reducing noise and improving overall comfort.
Conclusion: Building the Perfect Mechanical Keyboard
Understanding the essential components of a mechanical keyboard—such as switches, keycaps, PCBs, and more—can help you make informed decisions when purchasing or customizing your keyboard. Each part plays a vital role in delivering the best typing or gaming experience, whether you’re seeking smoothness, feedback, or sound customization.
By choosing the right combination of switches, keycaps, and other components, you can create a mechanical keyboard that perfectly suits your needs and preferences. Happy typing!
