Mechanical keyboards: They’re more than just input devices; they’re a tactile experience, a statement piece, and a tool for optimizing your workflow. Once relegated to the realm of hardcore gamers and keyboard enthusiasts, mechanical keyboards are now gaining mainstream popularity, and for good reason. From the satisfying click-clack to the increased typing accuracy and customizable aesthetics, a mechanical keyboard can transform your computing experience. This guide delves into everything you need to know about mechanical keyboards, helping you understand why they’re worth the investment and how to choose the perfect one for your needs.
What Makes Mechanical Keyboards Different?
Mechanical keyboards differ significantly from the more common membrane keyboards. The core difference lies in the switch mechanism under each keycap. Instead of a rubber dome that collapses to register a keystroke (as in membrane keyboards), mechanical keyboards use individual, spring-activated switches.
The Anatomy of a Mechanical Switch
Understanding the components of a mechanical switch is key to appreciating their distinct feel and performance:
- Keycap: The plastic cap you press.
- Stem: The moving part inside the switch, dictating its feel (linear, tactile, or clicky).
- Housing: The outer casing that holds all the switch components.
- Spring: Provides the resistance and bounce-back. Different spring weights result in different actuation forces.
- Contacts: The metal parts that make contact to register the keystroke.
Membrane vs. Mechanical: A Comparison
| Feature | Membrane Keyboard | Mechanical Keyboard |
| —————- | ————————————————- | ————————————————– |
| Key Feel | Mushy, less defined | Tactile, clicky, or linear |
| Actuation | Requires bottoming out | Often has an actuation point before bottoming out |
| Durability | Lower (typically 5-10 million keystrokes) | Much higher (typically 50-100+ million keystrokes) |
| Customization | Limited | Highly customizable (keycaps, switches, etc.) |
| Price | Generally more affordable | Generally more expensive |
| Repairability | Difficult or impossible | Easier to repair and replace individual switches |
Understanding Mechanical Keyboard Switches
The type of switch you choose is arguably the most crucial decision when buying a mechanical keyboard. Switches determine the feel, sound, and overall typing experience. Switches are usually categorized into three main types: Linear, Tactile, and Clicky.
Linear Switches
Linear switches provide a smooth, consistent feel from top to bottom, with no tactile bump or audible click. They are favored by gamers for their fast response times and smooth key presses.
- Popular Examples: Cherry MX Red, Cherry MX Black, Gateron Red, Gateron Yellow
- Characteristics: Consistent resistance, smooth actuation, generally quieter.
- Ideal For: Gamers, fast typists who prefer a smooth feel.
- Example: Imagine pressing a key on a piano – smooth and consistent motion.
Tactile Switches
Tactile switches provide a noticeable bump when the key actuates, giving you feedback that the key press has been registered. This feedback can improve typing accuracy and reduce fatigue.
- Popular Examples: Cherry MX Brown, Cherry MX Clear, Gateron Brown
- Characteristics: Tactile bump, moderate noise level, good for general use.
- Ideal For: Typists, programmers, users who prefer feedback on keystrokes.
- Example: You feel a slight “bump” as you press the key down, confirming the action.
Clicky Switches
Clicky switches provide both a tactile bump and an audible click when the key actuates. This makes them the loudest and most feedback-rich type of switch.
- Popular Examples: Cherry MX Blue, Kailh Box White, Razer Green
- Characteristics: Tactile bump, audible click, satisfying but potentially noisy.
- Ideal For: Users who enjoy the sound and feel of a click, don’t mind noise.
- Example: The classic “click-clack” sound associated with mechanical keyboards is primarily from clicky switches.
Actuation Force and Travel Distance
- Actuation Force: The amount of force needed to press a key far enough for it to register. Measured in grams (g). Lower numbers mean less force is required.
- Travel Distance: The distance a key travels from its resting position to its actuation point. Shorter travel distances can lead to faster actuation.
Choosing the right actuation force and travel distance can significantly impact your typing speed and comfort. A lower actuation force (e.g., 45g) may be preferable for those who type lightly, while a higher actuation force (e.g., 60g) might be better for those who want to avoid accidental key presses.
Keyboard Layouts and Sizes
Mechanical keyboards come in various layouts and sizes, each catering to different needs and preferences. The most common layouts are Full-size, Tenkeyless (TKL), 75%, 65%, and 60%.
Full-Size Keyboards (104/108 keys)
- Description: Include all standard keys, including a number pad, function row, and arrow keys.
- Pros: Full functionality, familiar layout.
- Cons: Larger footprint, less portable.
- Ideal For: Users who require a number pad for data entry or accounting, general all-purpose use.
Tenkeyless (TKL) Keyboards (87/88 keys)
- Description: Lack the number pad, resulting in a more compact design.
- Pros: More ergonomic (mouse closer to the center), more portable.
- Cons: Lacks a number pad.
- Ideal For: Gamers, programmers, users who want a more compact keyboard.
75% Keyboards
- Description: A more compact version of the TKL layout, usually placing the arrow keys vertically and the function row closer to the number row.

- Ideal For: Highly experienced keyboard users, users who prioritize portability above all else.
Keycaps and Customization
One of the most appealing aspects of mechanical keyboards is their extensive customization options. Keycaps are the most common way to personalize your keyboard.
Keycap Materials
- ABS (Acrylonitrile Butadiene Styrene): Common and affordable, but can become shiny over time due to wear (known as “shine”).
- PBT (Polybutylene Terephthalate): More durable and resistant to shine than ABS. Higher quality feel and texture. Generally more expensive.
- POM (Polyoxymethylene): Very smooth and durable, often used for specialty keycaps.
Keycap Profiles
Keycap profiles refer to the shape and height of the keycaps. Different profiles can affect typing comfort and aesthetics.
- OEM Profile: A common, sculpted profile with varying row heights.
- Cherry Profile: Similar to OEM but slightly shorter.
- DSA Profile: Uniform profile, all keycaps are the same height.
- SA Profile: Tall, sculpted profile, often associated with vintage keyboards.
Customization Options
Beyond keycaps, you can customize your mechanical keyboard with:
- Switches: As previously mentioned, you can replace the switches entirely. This is a popular option to fine-tune the feel of your keyboard.
- Cables: Coiled or custom-sleeved cables add a personalized touch.
- Cases: Replace the keyboard case for different materials, colors, or layouts.
- Dampeners: O-rings or other dampeners can be added to reduce noise.
Mechanical Keyboards for Gaming vs. Typing
The ideal mechanical keyboard for gaming differs from the ideal keyboard for typing.
Gaming Keyboards
- Key Features: Fast response times, anti-ghosting (ensures all keystrokes are registered), N-key rollover (allows multiple keys to be pressed simultaneously), programmable macros, customizable RGB lighting.
- Switch Recommendations: Linear switches (Cherry MX Red, Speed Silver) for fast actuation, tactile switches (Cherry MX Brown) for some feedback.
- Layout Recommendations: TKL or smaller layouts for more desk space.
Typing Keyboards
- Key Features: Comfortable keycaps, durable construction, tactile or clicky switches for feedback, ergonomic design.
- Switch Recommendations: Tactile switches (Cherry MX Brown, Clear) for comfortable typing, clicky switches (Cherry MX Blue) for feedback.
