In today’s digital age, mechanical keyboards have become increasingly popular among professionals, gamers, and typing enthusiasts alike. With their distinctive tactile feedback, audible click, and durability, mechanical keyboards offer a superior typing experience compared to traditional rubber dome keyboards. But what makes mechanical keyboards so special? In this article, we’ll delve into the science behind mechanical keyboards, exploring how they work and why they have gained such a dedicated following.
Understanding Mechanical Keyboards
At their core, mechanical keyboards are a type of keyboard that uses individual mechanical switches for each key, as opposed to rubber dome keyboards that use a rubber dome membrane. Mechanical switches are small mechanical devices that provide tactile feedback and actuate when a key is pressed. There are various types of mechanical switches, such as Cherry MX, Razer, and Romer-G, each with its own unique characteristics.
One of the key features of mechanical keyboards is the tactile feedback they provide. When a key is pressed, the mechanical switch registers the keystroke and provides a satisfying tactile bump, which gives typists a physical confirmation that the key has been actuated. This feedback allows for faster and more accurate typing, making mechanical keyboards popular among touch typists and those who need to type for extended periods.
Another factor that sets mechanical keyboards apart is their audible click. Some mechanical switches, such as Cherry MX Blue and Razer Green, produce a distinctive click sound when pressed, adding a satisfying auditory element to the typing experience. This click can also serve as an audible cue for typists, providing feedback on the actuation point of the key and helping them to type with precision.
Mechanical Keyboards vs. Membrane Keyboards
Mechanical keyboards and membrane keyboards are two types of computer keyboards that differ in their key-switch mechanism.
Mechanical keyboards use individual mechanical switches for each key. These switches are typically made of metal components and are designed to provide tactile feedback and audible clicks when pressed. When a key is pressed, the mechanical switch registers the input, and when the key is released, the switch returns to its original position, ready for the next input. Mechanical keyboards are known for their distinct “clicky” or “clacky” sound and are favored by many typists and gamers for their tactile feedback and responsiveness.
On the other hand, membrane keyboards use a rubber dome beneath the keys. When a key is pressed, the rubber dome collapses and makes contact with a circuit board, registering the input. Membrane keyboards are generally quieter and less expensive than mechanical keyboards, but they lack the tactile feedback and responsiveness of mechanical keyboards.
There are several advantages to using mechanical keyboards. Firstly, the tactile feedback provided by mechanical switches can improve typing accuracy and reduce the likelihood of accidental key presses. The audible click can also give typists an audible confirmation of each key press, which can be helpful for touch typists.
Secondly, mechanical keyboards typically have a faster response time compared to membrane keyboards. This is because mechanical switches register input as soon as they are pressed, while rubber domes in membrane keyboards may require more force to register a key press.
Thirdly, mechanical keyboards are generally more durable than membrane keyboards. The individual mechanical switches used in mechanical keyboards are designed to withstand millions of key presses, making them more reliable in the long run.
However, mechanical keyboards also have some downsides. They are usually more expensive than membrane keyboards due to the cost of the individual switches. They can also be louder, which may not be desirable in certain environments where noise is a concern.
Additionally, the tactile feedback and responsiveness of mechanical keyboards may be a matter of personal preference, and some people may prefer the softer feel of membrane keyboards.
In summary, mechanical keyboards use individual mechanical switches for each key, providing tactile feedback, faster response time, and improved durability compared to membrane keyboards. However, they can be more expensive and louder, and personal preference plays a role in choosing between the two types of keyboards. Overall, it’s important to consider your typing style, preferences, and budget when deciding between a mechanical keyboard and a membrane keyboard.
Anatomy of a Mechanical Keyboard
Let’s take a look at the anatomy of a mechanical keyboard and how its components work together to create a unique typing experience.

How Mechanical Key Switches Work
Mechanical key switches are a type of switch used in mechanical keyboards that utilize physical mechanisms to register key presses. They are different from membrane switches commonly used in rubber dome keyboards, which rely on a layer of conductive material to complete the circuit and register key presses.
There are several different types of mechanical key switch mechanisms, including linear, tactile, and clicky switches. Linear switches have a smooth keystroke from top to bottom without any tactile feedback or audible click. Tactile switches provide feedback through a bump or tactile point during the keystroke, giving the typist a physical indication that the key press has been registered. Clicky switches combine the tactile feedback with an audible click sound, providing both physical and audible feedback.
Mechanical key switches consist of several key components, including the stem, spring, and housing. The stem is the part of the switch that extends above the housing and is typically attached to the keycap. When a key is pressed, the stem moves downward, compressing the spring and closing the circuit, which registers the key press. The housing holds the other components of the switch in place and helps guide the stem’s movement.
The stem plays a crucial role in determining the type of switch mechanism. In linear switches, the stem moves straight up and down without any tactile feedback or click. In tactile switches, the stem has a bump or tactile point that provides feedback during the keystroke, giving the typist a tactile sensation. In clicky switches, the stem has a bump and also a mechanism that produces an audible click sound when the key is pressed.
The spring in a mechanical key switch provides the resistance or actuation force needed to press the key. The actuation force is the amount of force required to register a key press. It varies among different switch types and can be measured in grams. Higher actuation force switches require more force to press, which can result in a heavier typing experience, while lower actuation force switches require less force and may result in a lighter typing experience.
The travel distance of a mechanical key switch is the distance the stem travels from its resting position to the point where it actuates and registers the key press. It is typically measured in millimeters. Different switch types have different travel distances, with some switches providing shorter travel distances for faster typing speeds, and others providing longer travel distances for more deliberate and precise typing.
The reset point of a mechanical key switch is the point at which the key resets and is ready for another key press. After actuation, the stem needs to return to its original position before another key press can be registered. The reset point is typically above the actuation point, meaning the key needs to be released slightly before it can be pressed again. The reset point can affect the typing experience, with a higher reset point potentially allowing for faster repeated key presses and a lower reset point requiring more deliberate key release and press.
In conclusion, mechanical key switches are a type of switch used in mechanical keyboards that rely on physical mechanisms to register key presses. They consist of components such as the stem, spring, and housing, which work together to provide different types of switch mechanisms, actuation forces, travel distances, and reset points, all of which can affect the typing experience.
Understanding these key components and their functions can help users choose the right mechanical key switch for their specific typing preferences. Overall, mechanical key switches offer a tactile and customizable typing experience that is preferred by many typists for its responsiveness and durability. So, whether you are a gamer, a programmer, or a typist, understanding how mechanical key switches work can greatly enhance your typing experience on a mechanical keyboard.
How Mechanical Keyboards Work
Here’s a detailed explanation of how mechanical keyboards work:
- Mechanical Switches: The key component of a mechanical keyboard is the mechanical switch. Mechanical switches are small mechanical devices that sit underneath each keycap and register the keypress when activated. They come in different types, such as Cherry MX, Razer, and Romer-G, and each type has its own unique design and characteristics.

- Actuation and Reset Points: Mechanical switches have two important points – the actuation point and the reset point. The actuation point is the point at which the switch registers a keypress, and the reset point is the point at which the switch resets and is ready for another keypress. When you press a key on a mechanical keyboard, the keycap depresses the mechanical switch, which actuates the switch and sends a signal to the computer to register the keypress.
- Spring and Stem: Inside the mechanical switch, there is a spring and a stem. The spring provides resistance to the keypress and helps to reset the key after it’s released. The stem is a small rod that moves up and down when the key is pressed and releases the actuation point when the key is released.
- Electrical Contacts: When the key is pressed, the stem pushes two electrical contacts together, completing an electrical circuit and sending a signal to the computer to register the keypress. When the key is released, the contacts separate, breaking the circuit and sending another signal to the computer to register the key release.
- N-Key Rollover and Anti-Ghosting: Mechanical keyboards often come with N-key rollover and anti-ghosting features. N-key rollover means that you can press multiple keys at the same time without any missed or ghosted key presses. Anti-ghosting prevents unintended key presses from being registered when multiple keys are pressed simultaneously.
- Backplate and PCB: The mechanical switches are mounted on a backplate, which is a metal or plastic plate that provides stability and rigidity to the keyboard. Underneath the backplate is a printed circuit board (PCB) that routes the electrical signals from the mechanical switches to the computer.
- Controller: The controller is the brain of the mechanical keyboard. It processes the electrical signals from the mechanical switches and sends them to the computer as a series of digital codes corresponding to the keys that were pressed or released.
In summary, mechanical keyboards work by using individual mechanical switches for each key, which register keypresses through the actuation and reset points, electrical contacts, and a controller. The keycaps, springs, stems, and backplate all play crucial roles in the operation of mechanical keyboards, providing tactile feedback, durability, and customization options for users.
The result is a keyboard that provides a distinct typing experience, precise input, and increased durability compared to traditional rubber dome keyboards.
