Each type has its own unique set of characteristics and advantages, and understanding these differences can help you choose the right keyboard for your needs.
Membrane Keys
Membrane keys are the most common type of keyboard button and are found in most standard keyboards. They are made up of a series of rubber or silicone membranes that are sandwiched between two layers of metal or plastic. When a membrane key is pressed, it depresses the membrane and completes the electrical circuit, registering the keystroke. Membrane keys are relatively inexpensive to produce and are easy to implement in a variety of keyboard designs.
Mechanical Keys
Mechanical keys, on the other hand, are more complex and expensive to produce. They use a physical mechanism to register a keystroke, which allows for a more tactile and responsive typing experience. There are several different types of mechanical keys, including those that use a spring mechanism, a scissor mechanism, or a switch mechanism. Each type of mechanical key has its own unique set of characteristics, such as travel distance, actuation force, and sound, which can affect the overall typing experience.
Optical Keys
Optical keys are the newest type of keyboard button and use an infrared light beam to detect when a key has been pressed. This technology allows for a more precise and accurate keystroke detection, as well as a more durable and long-lasting keyboard design. Optical keys are typically found in high-end gaming keyboards and are often paired with other advanced features, such as customizable RGB lighting and anti-ghosting technology.
Overall, the type of keyboard button you choose will depend on your personal preferences and the specific needs of your application. Whether you prefer the tactile feedback of mechanical keys, the durability of optical keys, or the simplicity of membrane keys, there is a keyboard type out there that will suit your needs.
Keyboard Switches
Keyboard switches are the heart of any mechanical keyboard. They are responsible for registering when a key is pressed and sending that input to the computer. There are three main types of keyboard switches: linear switches, tactile switches, and clicky switches.
- Linear switches: Linear switches are the most common type of switch found in mechanical keyboards. They have a smooth, consistent output with no bump or tactile feedback. This makes them ideal for typing and gaming, as they provide a consistent and fast typing experience. Linear switches are also quiet, making them suitable for use in quiet environments.
- Tactile switches: Tactile switches provide a distinct tactile bump or feedback when a key is pressed. This bump can be felt through the keycap, making it easier to identify when a key has been pressed. Tactile switches are often used in keyboards designed for typing, as they provide a more tactile and satisfying typing experience.
- Clicky switches: Clicky switches provide a distinct audible and tactile feedback when a key is pressed. They are often used in keyboards designed for typing and gaming, as they provide a more satisfying and audible feedback when a key is pressed. Clicky switches are also suitable for use in noisy environments, as they provide a clear and distinct sound when a key is pressed.
How Keyboard Switches Work
Mechanical Keyboard Switches
Mechanical keyboard switches are the heart of any mechanical keyboard. They are responsible for registering keystrokes and providing the tactile feedback that makes typing on a mechanical keyboard such a unique experience.
There are many different types of mechanical keyboard switches, each with its own unique characteristics. Some of the most popular switches include Cherry MX Blue, Cherry MX Brown, and Gateron Blue.
One of the key components of a mechanical keyboard switch is the lever mechanism. This mechanism is responsible for converting the physical motion of pressing a key into an electrical signal that can be registered by the computer. The lever mechanism is typically made up of a stem, a spring, and a cap.
The stem is the part of the switch that is attached to the keycap. When the key is pressed, the stem moves downward, causing the spring to compress. The spring then pushes the cap against the stem, creating the tactile feedback that is characteristic of mechanical keyboards.
The keycap movement is another important aspect of mechanical keyboard switches. When a key is pressed, the keycap moves downward, creating a physical separation between the keycap and the keyboard. This movement is what allows the switch to register the keystroke.
The sound and feel of a mechanical keyboard switch are also important factors to consider. Some switches are designed to be quiet, while others produce a distinctive “click” sound with each keystroke. The feel of the switch is also important, with some switches providing a more tactile response and others offering a smoother, more fluid typing experience.
Overall, mechanical keyboard switches are a critical component of any mechanical keyboard. They are responsible for registering keystrokes and providing the tactile feedback that makes typing on a mechanical keyboard such a unique experience.
Optical Keyboard Switches
Optical keyboard switches are a type of keyboard switch that use an optical sensor to detect when a key has been pressed. Unlike mechanical switches, which rely on physical contact to register a keystroke, optical switches use a beam of light to detect when a key has been pressed.
Keycap Movement
One of the main advantages of optical keyboard switches is that they do not require physical contact to register a keystroke. Instead, the keycap is moved by a small motor that pushes it down when a key is pressed. This means that optical switches can be much more durable than mechanical switches, as there are no physical contacts that can wear out over time.
Sound and Feel
Another advantage of optical keyboard switches is that they produce a very distinct sound and feel when a key is pressed. This is because the keycap is moved by a motor, which produces a more distinct sound than the mechanical switches found in traditional keyboards. Additionally, the lack of physical contact means that the keys on an optical keyboard will feel smoother and more responsive than those on a traditional keyboard.
Overall, optical keyboard switches offer a number of advantages over traditional mechanical switches. They are more durable, produce a distinct sound and feel, and do not require physical contact to register a keystroke. However, they are also more expensive than traditional mechanical switches, and may not be as responsive for gamers or typists who require a high level of tactile feedback.
Keyboard Button Durability
Factors Affecting Durability
Switch Type
The switch type is a crucial factor in determining the durability of keyboard buttons. Different switch types have varying lifespans, ranging from tens of millions to just a few million keystrokes. For instance, the Cherry MX Red switches, known for their smooth and linear feel, have a lifespan of up to 100 million keystrokes. In contrast, the Cherry MX Blue switches, known for their tactile bump and audible click, have a lifespan of approximately 50 million keystrokes. It is important to note that while higher-end switches tend to be more durable, they may also come with a higher price tag.
Keycap Material
The material used to make keycaps can also impact the durability of keyboard buttons. Keycaps made from high-quality materials, such as double-shot PBT (polybutylene terephthalate), are more resistant to wear and tear compared to keycaps made from lower-quality materials, such as ABS (acrylonitrile butadiene styrene).
