Mechanical keyboard player-the introduction of mechanical keyboard can not be determined by subjective feelings such as feel and sound, but defined by structure. Each key has a separate switch (switch) to control the closing. This switch is also called "shaft". Although the cherry mechanical shaft is the most famous, there are other brands of mechanical shafts on the market, including the early Nissan ALPS shaft, the simple ALPS shaft in Taiwan Province Province and the White shaft in Taiwan Province Province. In fact, in the early days of keyboards, mechanical keyboards have already appeared and experienced a period of prosperity. For example, early servers were equipped with mechanical keyboards. Then it was quickly replaced by a cheap film keyboard, but the mechanical keyboard did not disappear. As a representative of high-end products, the characteristics of mechanical keyboard itself cannot be overwhelmed. Therefore, after the prosperity and decline of mechanical keyboards, the current situation is that more and more computer users and gamers put forward higher requirements for the comfort, feel and quality of using computers. As one of the peripherals, the keyboard has also undergone some changes, and the mechanical keyboard is no longer the favorite of enthusiasts.
