What is a Mechanical Keyboard? 7-Step Beginner’s Guide (2025)

Do your fingers feel fatigued after a long day of typing? Or perhaps you’ve heard a colleague’s satisfying click-clack sound and wondered why their typing experience seems so much better than yours. You are not alone. In a world dominated by flat, mushy laptop keys, a revolution is happening under our fingertips.

Welcome to the definitive guide on what is a mechanical keyboard. Unlike the standard membrane keyboards found in most offices, mechanical keyboards use individual physical switches for each key to register a press. This seemingly small difference fundamentally changes how you interact with your computer.

Here is a startling fact: According to recent market analysis, the global mechanical keyboard market size is expected to grow significantly by 2028, driven largely by professionals seeking better ergonomics, not just gamers. Switching to a mechanical board can potentially increase typing speed by up to 10% due to tactile feedback and key rollover capabilities.

In this guide, we will walk you through everything from switch types to a hands-on review of the premium NPKC RO75, ensuring you have the knowledge to make the right choice. Here is your roadmap:

  • The core differences between mechanical and membrane.
  • Understanding the "Switch" color codes.

1. The Basics: What Exactly is Under the Keycap?

To truly understand what is a mechanical keyboard, you have to look beneath the surface. Most budget keyboards use a "membrane" system—a rubber dome that you squash down to make a circuit connection. It feels mushy, inconsistent, and wears out relatively quickly.

In contrast, a mechanical keyboard uses a distinct physical switch for every single key. When you press a key, a plastic stem moves down, compressing a spring and closing metal contacts to register the keystroke. This mechanism provides:

  • Durability: Mechanical switches are rated for 50 to 100 million keystrokes, compared to 5-10 million for membranes.
  • Feedback: You can physically feel (and often hear) when the key acts, meaning you don't have to bottom out the key to type.
  • Customizability: From the keycaps to the switches themselves, almost every part can be changed.
Pro Tip: Not all mechanical keyboards are loud! The sound depends entirely on the "switch" type you choose (more on that in Section 3).

2. Mechanical vs. Membrane: The Showdown

Have you ever wondered why some keyboards cost $20 and others cost $150? The difference lies in the engineering and materials. Let's compare them side-by-side.

Feature Membrane Keyboard Mechanical Keyboard
Keystroke Feel Mushy, requires full press Crisp, consistent, distinct actuation point
Durability Low (Rubber degrades) High (Metal springs and contacts)
Rollover (N-Key) Low (Ghosting issues) Full N-Key Rollover (Press all keys at once)
Maintenance Difficult to clean Easy (Remove keycaps to clean)
Customization None Limitless customization options

3. Decoding the Switches: Red, Blue, or Brown?

The soul of a mechanical keyboard is the switch. Manufacturers color-code these stems to indicate their feel. If you are looking for the best mechanical keyboard for typing, understanding this is crucial.

Linear Switches (Usually Red or Black)

These are smooth from top to bottom. There is no "bump" or "click." They are favored by gamers for their speed and by office workers who prefer a quieter experience. The Supermy Red switches found in premium boards are a prime example of this smooth action.

Tactile Switches (Usually Brown)

These provide a small physical "bump" halfway through the press to let you know the key has registered, but without a loud click. This is often considered the middle ground for typists.

Clicky Switches (Usually Blue)

These have a tactile bump and an audible click sound. They are satisfying to some but can be annoying to coworkers in a shared space.

First Impressions & Build Quality

The first thing you notice is the weight. The CNC Aluminum Case gives it a hefty, premium feel that anchors it to your desk—no sliding around while gaming. Unlike cheap plastic shells, this feels like an industrial tool built to last.

The Typing Experience

Equipped with Supermy Red Switches, the typing feel is incredibly smooth (linear). There is no grit, just a clean up-and-down motion. Because the board uses a Gasket Mount structure (a feature usually reserved for $300+ keyboards), there is a slight, pleasant flex that cushions each keystroke, reducing finger fatigue significantly.

Key Features Breakdown

  • Triple Mode Connectivity: You can connect via Bluetooth 5.0, 2.4GHz Wireless (lag-free), or USB-C Wired. Switching between my Mac and PC was seamless.
  • Hot-Swappable PCB: This is a game-changer. If you ever want to try different switches, you can simply pull the old ones out and plug new ones in. No soldering required.
  • South-Facing RGB: For the aesthetic lovers, the RGB lighting is vibrant and customizable, shining through clearly even with custom keycaps.

Pros & Cons

✅ Pros

  • Premium CNC Aluminum build at a competitive price.
  • Gasket mount offers a superior, soft typing feel.
  • Supermy Red switches are factory-lubed and smooth.
  • 3-Mode connectivity fits any workflow.

❌ Cons

  • Heavier than plastic boards (less portable).
  • 75% layout might take getting used to if you need a numpad.

Verdict: For beginners and enthusiasts alike, the RO75 represents incredible value. It skips the need for modding because it sounds great out of the box.

5. Size Matters: Finding Your Perfect Fit

You might ask yourself, "Do I really need the number pad?" Mechanical keyboards come in various sizes, expressed as percentages of a full-sized board.

  • 100% (Full Size): Includes number pad, function row, and arrow keys. Best for data entry.
  • 75% (Like the RO75): The "Goldilocks" size. It keeps the F-row and arrows but chops off the number pad to save desk space for mouse movement. It is increasingly the most popular layout.
  • 60%: No arrows, no F-row, no numpad. Extremely compact but requires memorizing key combinations.

6. Common Buying Pitfalls to Avoid

As an editor who has tested dozens of boards, I have seen buyers make the same mistakes repeatedly. Here is how to protect your wallet.

  1. Ignoring "Hot-Swap" Capability: Always buy a hot-swappable board in 2025. If a switch breaks or you get bored of the feel, you can change it easily. If it's soldered, you are stuck.
  2. Overlooking Keycap Material: Look for "PBT" keycaps rather than "ABS." PBT plastic does not develop that greasy shine over time.
  3. Buying for "Gaming" Branding: Often, major "Gaming" brands charge a "gamer tax" for inferior build quality. Custom-oriented brands like NPKC often offer better materials (like aluminum cases) for similar prices.

7. FAQ: Your Questions Answered

Is a mechanical keyboard really better for typing?

Yes. The tactile feedback and distinct actuation point allow you to type without "bottoming out" the keys, which can reduce finger impact and increase typing speed and accuracy over time.

Are mechanical keyboards too loud for an office?

Not necessarily. Avoid "Blue" or "Clicky" switches. Instead, opt for "Red" (Linear) or "Brown" (Tactile) switches, and look for keyboards with sound-dampening foam, like the NPKC RO75, which are often quieter than standard office keyboards.

What does "Hot-Swappable" mean?

Hot-swappable means the switches are not soldered to the circuit board. You can pull them out with a simple tool and insert different switches to change the feel of the keyboard without needing any technical skills.

Video: Once you get advanced, you can even "lube" your switches for better sound. Here is how.
