Hello keyboard enthusiast! If you‘re reading this, you likely already appreciate quality keyboards or are looking to upgrade from the cheap plastic slab bundled with your computer.
You may have heard gamers, programmers and typing addicts rave about "mechanical keyboards" and wondered – what‘s the big deal? Is it just hype? Or are mechanical boards genuinely better tools for interacting with your PC?
I‘ve tested hundreds of keyboards over my 20 years as an input device analyst and routinely recommend mechanical models over standard membranes. In this guide, I‘llexplore what exactly makes mechanical keyboards special, how they work, and why they provide a superior typing experience.
What Are Mechanical and Membrane Keyboards?
First, let‘s clearly define these terms, since the keyboard world loves jargon!
Mechanical keyboards use individual spring-loaded mechanical switches for each separate key on the board. These switches have metal contacts and a spring inside that register a keypress when the stem is pressed down.
Membrane keyboards use a single sheet of flexible membrane material with a matrix of circuits printed on it. Rubber domes provide springiness to collapse onto the circuit when a key is pressed.
So mechanical boards have discrete switches under every key, while membrane boards use a single molded sheet with domes. This fundamental construction difference affects durability, feel, sound, and performance.
Evolution of Keyboard Design
Early electronic typewriter keyboards used complex mechanical linkages underneath each key to trigger imprint hammers. This evolved into spring switch boards like the iconic IBM Model M PC keyboard known for its solid feel and durability.
In the 90‘s, membrane rubber dome keyboards emerged as a simpler, cheaper way to manufacture keyboards for the booming home PC market. For the next 20 years, these basic designs persisted as the default keyboard included with desktops.
Meanwhile, niche communities of programmers, writers and gamers continued using high-end mechanical keyboards for their performance, comfort and customization. As computer gaming exploded in popularity, the gaming community led a renaissance of interest in mechanical boards.
Now, mechanical keyboards are thriving with dozens of manufacturers making keyboards catering to esports pros, developers, writers and keyboard enthusiasts.
Next we‘ll explore what exactly makes them better tools for interfacing with computers.
How Mechanical Keyboards Work
A mechanical keyboard uses individual mechanical switches connected in a switch matrix to register key presses. Let‘s break this down…
Switch matrix – The underlying printed circuit board has rows and columns of conductive traces. Each mechanical switch connects a specific row and column. The keyboard processor scans these rows/columns to detect when a circuit is completed by a pressed switch.
Mechanical switches – Unlike rubber dome sheets, discrete mechanical switches give each key its own mechanism providing tactile feedback and registering presses. The most popular style of switch is the Cherry MX design used by major gaming brands.
Switch specifications – Switches have technical specifications like actuation force, travel distance and lifespan ratings over tens of millions of presses without failure. These determine the feel and expected durable lifetime of a keyboard.
Specialty switches – Unique mechanical switch types provide customized feels and properties beyond the basic Cherry MX palette: Topre electrocapacitive switches offer buttery smooth travel, while optical switches use infrared beams for fast actuation without metal contact wear.
Debouncing – Switch contacts can bounce open and close several times when pressed, registering multiple erroneous signals. Debouncing circuitry and firmware filters ensure only a single key press is registered, optimizing typing accuracy.
So properly designed mechanical keyboards combine advanced switch mechanics, scanning processing, and electrical engineering to deliver a premium typing experience.
Ergonomics and Health Benefits
Studies of computer workers suggest traditional keyboards contribute to muscular issues including wrist pain and repetitive strain injuries over long-term use.
Prolonged awkward posture from keyboard use places stress on tendons in the hands and wrists. Carpal tunnel syndrome from compressed nerves affects up to 20% of full-time computer users (Source).
Research identifies ergonomic factors in keyboard design that reduce injury risk:
- Split adjustable keyboard halves
- Vertical column key alignment
- Low-force chicklet style switches
Many mechanical keyboards now specifically integrate these ergonomic principles:
-
High-end mechanical switches are engineered for light actuation force between 45-55 grams versus 60+ for most rubber dome keys. Reducing press force decreases fatigue.
-
Sculpted keycap profiles with curved dishes or front-height angles better match natural finger positions when typing. This avoids awkward bending that stresses joints.
-
Specialty split and columnar layouts allow a more natural hands-apart posture and eliminate lateral finger reaching.
So while traditional membrane keyboards with their high fixed typing force contribute to strain over time, custom mechanical keyboards actively reduce injury risk – while still providing precision and responsiveness for developers, writers and power users.
Customization and Community
Beyond pure performance, perhaps the most fun distinction of mechanical keyboards is the personal customization possible.
While cheap membrane boards come in basic black with little cosmetic variation, mechanical keyboards enable seemingly endless mods and aesthetic enhancements.
Entire Reddit and Discord communities of keyboard fans share photos and suggest ideas for customized mechanical boards. The r/MechanicalKeyboards subreddit has over 450,000 members discussing mods ranging from subtle to radically transforming.
Some popular custom upgrades include:
Keycaps – Hundreds of replaceable keycap sets in different plastics, fonts, colors and sculpted profiles are available to personalize a board‘s look and feel. Signature keycaps with custom novelties and themes let you flaunt your interests.
Switches – Boards with hot-swap switch sockets allow safely removing switches without any soldering to swap in new ones with different feel, color or properties. Change your keyboard‘s personality on a whim!
Cables – Coiled aviator-style detachable cables come in unlimited color combinations to complement keycap colorways and underlighting themes.
Chassis – Open frame chassis show off RGB lighting effects; translucent cases embed vivid RGB shining directly through switch housings.
In the membrane keyboard world, you‘re limited to buying whatever cheap design a manufacturer churns out. But mechanical keyboards empower creativity both visually and functionally.
Performance Gains for Gaming
While ergonomics and customization make mechanical boards great for developers and writers, ultra responsive performance is what makes them the choice of serious gamers.
Specialized gaming mechanical keyboards provide measurable competitive advantages:
- Hair-trigger switch actuation under 1ms rapidly registers key presses the instant you touch a key, translating to quicker in-game reactions.
- N-key rollover (NKRO) ensures all simultaneous key presses correctly register at once, enabling complex combo moves. Cheap boards may "ghost" inputs when gaming under pressure.
- Onboard programmable memory stores your custom macros and keymaps for tournament consistency across systems.
Esports professionals attuned to millisecond differences swear by high-end mechanical boards to maximize their talents during clutch moments.
Direct Comparison
Let‘s summarize the key factors distinguishing quality mechanical keyboards versus common membrane boards in a direct side-by-side comparison:
| Factor | Mechanical Keyboard | Membrane Keyboard |
|---|---|---|
| Feel | Tactile, responsive | Mushy, indistinct |
| Sound | Customized clickiness | None, keys bottom out |
| Actuation Force | 45-60 grams | 60+ grams |
| Ergonomics | Excellent | Mediocre |
| Customization | Endless creative options | Very limited |
| Durability | 50-100 million key presses | 5-10 million presses |
