AI Technical Summary
In the existing mechanical keyboard switch structure, the hard collision between the switch core and the bottom cover produces a noticeable and noisy knocking sound, which affects the user's operating experience and concentration.
Multiple cylindrical contact elements arranged in a ring array are set on the inner wall of the lower cover. Through embedded fixing and anti-friction coating design, the surface contact between the shaft core and the lower cover is transformed into point contact. The guide groove ensures the vertical movement of the shaft core, reducing rigid collisions and friction noise.
It effectively reduces the clicking sound, improves the trigger sensitivity and stability of the buttons, and enhances the user experience.
