What Is an Overlay Keyboard?

Mechanical keyboard (English: Mechanical Keyboard) is a type of keyboard. In terms of structure, each key of the mechanical keyboard has a separate switch to control the closure. This switch is also called "axis". Classification of switches, mechanical keyboard can be divided into traditional tea axis, green axis, white axis, black axis, red axis, Romer-G and optical axis . It is precisely because each button is composed of an independent micro-motion, so the button feels strong, which produces a special feel suitable for game entertainment, so it is usually used as a relatively expensive high-end gaming peripheral.

1. The mechanical keyboard is the most important. The mechanical keyboard is more than ordinary

Mechanical keyboards have appeared in the early days of keyboards, and they have experienced a period of prosperity. For example, mechanical keyboards were equipped on early servers. It was soon replaced by an inexpensive film keyboard, but the mechanical keyboard has not disappeared. It has been developed as a representative of high-end products to this day. The characteristics of the mechanical keyboard itself cannot be overwhelmed. Therefore, when the mechanical keyboard experienced prosperity and decline, Since then, the status quo today is that more and more computer users and gamers have put forward higher requirements for the comfort, feel and quality of using the computer, and some changes have occurred to the keyboard as one of the peripherals. Mechanical The keyboard is no longer just a favorite of enthusiasts, and it is beginning to be recognized by more and more friends who seek quality and feel.

In recent years, another spring of mechanical keyboards has arrived. The most representative are Cherry original keyboards known for their excellent quality. Filco, which wins with a stylish, exquisite, simple appearance, but maintains a high production process, and game players. There is a higher status of SteelSeries in the mind.

Xuli Silitek, Chicony CHICONY, Yingqun BTC, Minebea NMB, undertake the OEM manufacturing of keyboards from world-renowned brands such as Microsoft, Logitech, IBM, HP, etc. But mechanical keyboards from these four foundries are very rare. So which factory produces many mechanical keyboards from Taiwan?

That is the controversial and closed Shengchun, from Steel 6G, 6G2 in Denmark, jazzykit in Taiwan to filco in Japan, etc., which are manufactured by Shengchun, there have been certain problems, so these products Has been the subject of controversy among players. jAKi JD002 is the successor to jazzykit JD001. Although the foundry has been replaced, it is still produced in Taiwan. So Taiwan is another rich place for mechanical keyboards. In addition, the current popular filco is produced by Taiwan Libao, and the SteelSeries 7G and 6Gv2 are produced by Taiwan Mingzhe.

Mechanical keyboard Germany

First look at Cherry, which everyone is most familiar with, a German brand established since 1953, and has established 12 companies and factories in the United States and around the world. Cherry's mainstream mechanical keyboards in the market are mainly produced in Germany and the Czech Republic, two highly developed mechanical manufacturing countries.

Mechanical keyboard Japan

Speaking of Japan, probably the first thing that keyboard enthusiasts think of is the Realforce101 capacitive keyboard, which has the same characteristics as a mechanical keyboard with a long life and a good feel. It is easy to be confused as a mechanical keyboard. Although its principle is completely different from a mechanical keyboard, As a type of high-end keyboard, it is specifically mentioned here.

In addition, the ALPS axis mechanical keyboard was once also very popular from Japan, but it has been discontinued for a long time. Later, it was improved by Taiwan manufacturers to form ALPS axis and simple ALPS axis, but the source is still from Japan.

Mechanical keyboard USA

The representative is IBM's curved squat spring film keyboard. The full name of this keyboard that was very active in the 286 era is buckling spring flexion spring shaft film mechanical keyboard, (buckling spring means spring that bends) and it is a mechanical switch keyboard. There is a big difference. Some people say that typing with it is just like playing beautiful music in front of the piano. It is sturdy and durable, and it is not easy to damage, so that they can still be circulated on the market even if the normal age has expired.

The structure is a double-layer keycap. Each layer of the keycap has a spring. Five layers of thin film sheets form a switch circuit on a metal disk. The upper black piece is made of rubber to protect the thin film piece. Layer of carbon film, the upper contacts are printed well. There is another layer of printed circuits and contacts, but if the two pieces are placed directly, each contact will be in a long-term connection.

When you press the keycap for nearly 3/4 of a stroke, the spring reaches the compression limit, and then it instantly bends and hits the inner wall to make a clicking sound. At the same time, due to the change of the angle, the lower module is pressed by the lever principle and contacts the lower film. Turn on the switching circuit. The key to achieving this clever design is the angle of the internal structure of the keycap.

This kind of keyboard has been discontinued due to its high cost. In order to control the overall cost of the PC, it is still very active in the market due to its irreplaceable feel and excellent quality.
