Näppäinhatut

Näppäinhatut, known in English as keycaps, are the removable covers that sit atop the stem of a mechanical keyboard switch. They are a fundamental component that directly influences the typing experience, aesthetics, and even the sound of a keyboard.

The primary function of a keycap is to provide a surface for the user to press. They come in a vast array of shapes, sizes, and profiles, which describe the curvature and height of the cap. Common profiles include Cherry, OEM, SA, and DSA, each offering a distinct feel and ergonomics. The material from which keycaps are made also plays a significant role. ABS (Acrylonitrile Butadiene Styrene) is a common and affordable plastic, often used for its shine and vibrant color possibilities. PBT (Polybutylene Terephthalate) is a more durable and denser plastic, known for its textured finish and resistance to yellowing and wear.

Keycaps are also a major avenue for keyboard customization. They are available in countless colors, designs, and legends (the characters printed on the keycap). From simple, uniform sets to intricate themed designs and artisan keycaps crafted by individual artists, the options for personalizing a keyboard's look are virtually limitless. The method of legend printing, such as dye-sublimation, double-shot injection, or laser etching, affects their longevity and appearance. The choice of keycaps can transform the look and feel of a keyboard, making them a popular subject of interest within the mechanical keyboard enthusiast community.
