A mechanical keyboard PCB is so precise with special tactile feedback that it allows you to have super fast and precise execution of each click, and in its duration longer than any other keyboard by such a type of keyboard. Due to its unique architecture, incredible durability and ultra-fast responsiveness, its demand is growing every day.

Depending on the switch, there are usually two types of computer keyboards. The first is a PCB membrane keyboard, which is easily available in the market, which is why it is used in all situations. The other is a mechanical keyboard. Currently, there is no substitute for gaming mice and mechanical keyboards for gamers. Many people are interested in using mechanical keyboards for all reasons such as response time, build quality, appearance and RGB. Since it is not like a traditional keyboard, its price is higher than that of a normal keyboard. Mechanical keyboards are now widely used by gamers, but now many content creators use mechanical keyboards. In games or typing, the mechanical keyboard brings a new typing experience. However, depending on the price, brand and type of switch, the fun of using a mechanical keyboard is different. Moreover, if there are RGB LEDs on the keyboard, you can change the color of the keys as needed. Mechanical keyboards are usually made of PCB printed circuit boards and switches. Metal objects and springs are used inside the switch. When two metal objects touch the key, the key is registered. Since the mechanical keys are located on the printed circuit board, if the switch does not work, the switch can be replaced. One of the main differences between mechanical keyboards and membrane keyboards is that, unlike mechanical keyboards, they do not have separate key switches. Place the rubber dome on top of the film sheet to register it on the keyboard when the key is pressed.

For mechanical keyboard PCB, there are 3 types of keyboard switches.

Linear

touch

Clicky

These three types of switches have some unique characteristics, called the color of the switch.

Linear: Black Cherry MX, Red MX, Linear Gray MX, Logitech R G

Touch: Cherry MX brown, MX transparent, MX tactile, razor orange GT

Click "Switch": Razor Cherry MX blue, MX green, MX white and chroma green GT.

This is Logitech's Cherry, and Razor is the brand of the switch manufacturer. One of the most popular is Cherry MX Switch. Cherry is a company located in Germany. Many Chinese switch manufacturers also manufacture mechanical switches in the form of Cherry MX switches. For example, Otemu, Gritech, GETRON, etc. Most importantly, there are now optical mechanical switches that feel similar to mechanical keyboards, and keyboards claim to have faster response times. However, depending on the name of the switch, the switch will be clickable, muted or tactile. In most cases, we say that the toggle click refers to the blue switch. When typing on the keyboard, the click sound provides a comfortable feeling. Tactile switches usually don't click, but they do have tactile feedback. Like Cherry MX Brown or Razor Orange Switch. On the other hand, linear switches are very quiet, and there is no click or feedback like linear switches. Like Cherry MX Black and MX Red, in the early 1970s, the IBM keyboard was one of the first keyboards known for its capacitive sensor beam spring switch. In the past, on the keyboard, capacitive sensing technology is similar to touch screen technology. It works exactly the same as the touch screen, but there is a small pad under the switch under the finger, which can simulate your finger instead of using your finger directly. Touch the screen. To increase electrode capacitance. In the end, this technology gave way. The way the beam spring behaves is unique. When pressed, some internal parts will reverse and rise. The keyboard feels almost like using a typewriter. The real goal of developing something that makes people feel like a real typewriter. Because at that time most people were familiar with the sound and nose of a typewriter. The keyboard is beautiful because it has two keystrokes, a separate space bar and a huge weight of 10 pounds. Her voice is louder than that of the IBM model. It also uses a solenoid that triggers with every click, making a louder noise and giving a more printed feel. However, the size and weight of this keyboard are very large and impractical. Moreover, it is very expensive, in 1970 its price was 1,500 US dollars, according to today's market price is 8,000 US dollars. IBM has been producing some of the best keyboards for decades, and the Model F switch is one of the best. The main goal is to provide the same typewriter feel in a more compact size frame at a lower cost, and this method has been successful. Nowadays, professional typewriters prefer the mechanical keyboard circuit board, because in the membrane keyboard, it is likely to fall when you press it. This means that you think you have pressed it, but you cannot use it because the membrane cannot touch the keys. There are great possibilities in the keyboard. If you click the switch, it will definitely respond due to its unique mechanism.
