Although these "shafts" are good to the touch, they are switched by closing a switch of a metal part, which causes a delay. In addition, the oxidation phenomenon of the metal contact points can also occur under the long-time use even if gold or silver metal with extremely low oxidation speed is plated on the contact points, and in addition, the environment used by each mechanical keyboard is different, air is humid, and sulfide and acidic substances in the air are higher, so that the oxidation and blackening of the metal contact points are directly aggravated, and the problems of double-click, continuous click, no response and the like of the keyboard are caused.

Therefore, in recent years, photoelectric switches developed based on optical principles and optical coupling technologies have gradually emerged, and due to the characteristics of optical sensing principles, no contact, zero abrasion and long theoretical life, photoelectric switch keyboard products are beginning to emerge in the market.

In order to realize the two-touch impact sound of the simulated mechanical keyboard shaft, a completely independent new structure for generating the paragraph-touch impact sound is adopted, but noise is generated in some occasions needing silence, such as meeting occasions or night work, so that rest of other people is influenced. The application scene range of the switch module for generating the two-time touch impact sound and controlling the integrated input equipment by the photoelectricity is narrow.
