Parts of a Mechanical Keyboard

Before we begin to delve into the nitty gritty of mechanical keyboard cases, we need to understand the parts of a mechanical keyboard. A mechanical keyboard is a keyboard using individual mechanical switches for each key. In contrast, a standard membrane keyboard uses rubber dome or membrane switches under the keys.

A mechanical keyboard consists of several key components, each playing a crucial role in its functionality and overall design. Here are the main parts of a typical mechanical keyboard:

  1. Case: The case is the outer shell of the keyboard that houses all the internal components. Keyboard cases can be made from various materials, including plastic, aluminum, wood, and more. The design and material of the case can greatly affect the keyboard's aesthetics and durability.
  2. Keycaps: Keycaps are the visible part of the keyboard that you press when typing. They are usually made of plastic and have the letters, numbers, and symbols---called legends---printed on them. PBT and ABS keycaps are the most common. Keycaps can vary in shape, size, and material. In general, they can be removed or replaced when customizing or building your own keyboard. 
  3. Mechanical Keyboard Switches: The switches are the heart of a mechanical keyboard. Each key on the keyboard has its own switch underneath it. When you press a key, the switch registers the keypress and sends an electrical signal to the computer. Different types of mechanical switches provide various levels of tactile feedback, actuation force, and sound. Popular switch brands include Cherry MX, Razer, and Gateron, among others.
  4. Stabilizers: Stabilizers are used for larger keys like the spacebar, enter key, and shift keys to prevent wobbling and ensure consistent keypresses. They come in various designs, including plate-mounted and PCB-mounted stabilizers.
  5. PCB (Printed Circuit Board): The PCB is the circuitry that connects the switches to the computer. Each switch is soldered onto the PCB, and the PCB translates keypresses into electrical signals that are sent to the computer. In hotswap keyboards, the PCBs are designed in such a way that you don't need to solder or desolder the switches. 
  6. Microcontroller: The microcontroller is the brain of the keyboard, responsible for processing keypresses and sending them to the computer. It may also handle other functions, such as controlling backlighting and macros.
  7. LEDs and Backlighting: Some of the best mechanical keyboards come with LEDs for backlighting, allowing users to customize the keyboard's lighting effects and colors. These LEDs are often used for both aesthetic and practical purposes.
  8. Plate: A metal plate is a rigid sheet that sits between the switches and the PCB. It provides structural support to the keyboard and helps prevent the switches from wobbling or flexing when keys are pressed. The keyboard plate also affects the sound and feel of the key presses.
  9. Cable: The keyboard's cable connects it to the computer's USB port. Some mechanical keyboards have detachable or braided cables for easy transport and durability.
  10. Feet and flip-out stands: Many mechanical keyboards have adjustable feet or flip-out stands on the underside to change the typing angle and ergonomics. This allows users to customize the keyboard's tilt for comfort.

Depending on the keyboard's design and features, there may be additional components or accessories such as wrist rests, detachable cables, extra USB ports, media keys, and more, which can further enhance the overall typing and gaming experience.
