Keycaps are the small covers that sit on your computer keyboard. They are made of plastic, metal, or other materials and fit over the keyswitches. Keycaps indicate the function or character of each key. They not only protect the keys but also allow for customization and personalization of your keyboard.

The keys on a keyboard are arranged in a specific layout. Each key consists of two parts: the visible top portion known as a keycap or keytop, and the underlying mechanism that registers keystrokes.


 

How Do Keycaps Work?

Keycaps are designed to fit securely onto the stems of the switches

Keycaps are designed to fit securely onto the stems of the switches. They align with the switch housing and sit directly on top of the switch mechanism. When you press a keycap, it applies pressure to the switch's stem, triggering the switch mechanism and registering the keystroke. Keycaps provide stability, alignment, and tactile feedback, while also allowing for customization of the keyboard’s appearance.

Keycaps play a crucial role in both functionality and aesthetics. They are the visible covers that sit atop the switches, giving each key its distinctive look and feel. ABS and PBT are two types of plastics widely used in making keycaps.

Material Advantages Disadvantages
ABS Lightweight and durable plastic. Easy to customize with vibrant colors. Affordable. Prone to shine and wear over time.
PBT Denser and more durable thermoplastic. Textured surface for a grippy feel. Resistant to oils and shine. Limited color options compared to ABS.
Resin Versatile material for custom keycap designs. Allows for intricate patterns and color effects. May not be as durable as other materials. Requires careful casting and finishing processes.
Metal Provides a premium feel and exceptional durability. Adds elegance and sophistication to your keyboard. Higher cost compared to plastic options.

 

Purpose of Keycaps

Keycaps are used to signify letters and symbols

Keycaps are used for key identification and act as a protective layer for the underlying keyswitches. However, today, they also serve to decorate the keyboard and make it unique.

  • Key Identification: Keycaps feature legends or labels that indicate the function or character of each key. This makes it easier to identify specific keys, especially for those who use specialized keyboard layouts.

  • Aesthetics and Personalization: Keycaps offer a chance to customize the look and feel of your mechanical keyboard. From vibrant colors to unique designs, keycaps allow you to express your personal style. Artisan keycaps are highly sought-after collectibles crafted by independent artisans, adding a touch of artistry and individuality.

  • Typing Experience: Keycaps can significantly affect the typing feel. Different materials, profiles, and textures can alter the tactile feedback and overall typing experience.

  • Noise Dampening: Keycaps can influence the sound produced when typing. Thicker keycaps, such as those made of PBT, tend to produce a deeper and more muted sound.

  • Backlighting: Keycaps can also impact the visibility of keyboard backlighting. Keycaps with translucent or semi-transparent legends allow the backlighting to shine through, enhancing visibility in low-light environments.


 

Different Types of Keycaps

Some of the most common keycap profiles

There are different types of keycaps for specific keyboard layouts or sizes. Factors that differentiate them include profile (shape), height, material, design, surface texture, and compatibility.

  • OEM Profile: The most common and widely used keycap profile. It features a slightly curved top surface and a cylindrical shape, providing a comfortable and familiar typing experience.

  • SA Profile: The SA profile offers a distinctive spherical shape and a taller height. It delivers a comfortable typing experience and a vintage aesthetic reminiscent of classic typewriters.

  • DSA Profile: The DSA profile features a flat, uniform profile with a diamond-shaped top surface. It offers a sleek and minimalist appearance and is known for compatibility with a wide range of layouts.

  • Cherry Profile: The Cherry profile is another widely recognized and popular keycap profile. It features a lower profile compared to OEM, providing a shorter key travel distance and a more compact look.

Keycaps undergo an intricate manufacturing process:

  1. Material Selection: Durable ABS or PBT plastics are often chosen, or artists may use unique materials like resin or clay.

  2. Injection Molding: The melted material is injected into precise molds to form the keycap's shape.

  3. Cooling and Demolding: Keycaps cool and solidify before being demolded.

  4. Post-Processing: Refining and polishing create a smooth surface for customization.

  5. Legends and Customization: Legends are added through printing, laser etching, or double-shot molding.
