A scissor switch keyboard has keys held closer to the keyboard, increasing longevity and responsiveness but making cleaning harder. The X-shaped switch limits key movement, increasing lifespan, but makes it harder to clean under keys. Scissor switches are more expensive but offer better typing experience and aesthetics.
A scissor switch is a type of switch that attaches keys to a keyboard and has a scissor shape. Unlike other keyboard switches, which hold the keys at a distance from the keyboard, a scissor key is often closer to the keyboard itself, minimizing the distance by about half. Helping to keep the keys in place, this thick switch increases the longevity of the keyboard. It makes it harder to get particles under the keys, but also harder to clean the area. This switch typically raises the price of a keyboard, because the keys are generally considered to be more comfortable for typing and more responsive.
Most keyboard switches are designed to hold the keyboard key approximately 0.15 inches (4 millimeters) away from the keyboard, but a scissor switch only holds the key approximately 0.07 inches (2 millimeters) away from the keyboard . This is the result of the shape of the switch. Normal switches are straight pieces of plastic, but a scissor switch uses an X-shaped piece of plastic that is able to hold the key closer while remaining responsive.
Most keyboards have keys that move slightly because they are only held in one spot in the center. This motion causes excessive wear on the keys and switch, which can result in decreased key life. With the scissor switch, the switch covers the entire key area. While this doesn’t completely eliminate movement, it drastically limits it. The keys can’t move freely, so they often last 5 million to 10 million keystrokes longer, on average, than the keys on a standard keyboard.
Particles often end up under keys, even if the user doesn’t intend for that to happen. Prolonged exposure to particles can reduce responsiveness or destroy keys. With a scissor switch, the chance of particles getting under the keys is reduced, but this creates its own problem. The keys are much lower and not as easy to pull out, which means it’s also more difficult to clean the area if dirt gets under them.
When comparing the different types of keyboard switches, a keyboard with a scissor switch type will usually be more expensive than a basic keyboard. The keys are often more responsive, and users may find it easier to type on these keyboards because the keys open much faster after being pressed. Some people also prefer the aesthetics of the keys over those used with other switches.
