Description

Mechanical keyboard switch {MECHANICAL KEYBOARD SWITCH}

The present invention relates to a mechanical keyboard switch, and more particularly, to a mechanical keyboard switch that minimizes a noise problem that occurs when typing on a mechanical keyboard.

A keyboard refers to a device for inputting a program or data by sending a signal by pressing a key of a character desired by a user in relation to an electronic product such as a computer. Such a keyboard may be divided into a capacitive keyboard and a mechanical keyboard according to a method of detecting a pressed state of a key or a method of transmitting a current. Here, the mechanical keyboard refers to a keyboard that detects the press of a key by the flow of current by attaching and detaching the two metals under the key, and a mechanical keyboard switch refers to one of the keyboard keys It is configured to convert the physical movement that the user presses into an electrical signal.

A mechanical keyboard works by generating a current signal by connecting the two broken metal circuits on the board as the metal plate of the key touches the bottom plate when a key is pressed. Restoration of the key is accomplished by the force of the spring.

Mechanical keyboards are characterized by a loud sound whenever a key is pressed, and there are many people who prefer mechanical keyboards because they have a sense of time when the keys are struck. However, when a key is pressed, the sound is so loud that it is sometimes perceived as noise. Therefore, a noise problem occurs in the case of a mechanical keyboard used in a quiet office or a person who is sensitive to noise.
