Problems solved by technology

The thin mechanical keyboard for laptop computers connects the keycap and the reinforced iron plate respectively through the scissors feet, and keeps the balance of the keycaps by the scissors feet in the process of pressing down the keycaps, and realizes the strike through the sound parts and contact shrapnels vertically arranged in the base. The sound of the sound and the conduction of the line, the vertically arranged sound parts and the contact shrapnel are placed in the base with the push button, which has the following disadvantages: 1. Due to the large thickness of the push button and the vertical arrangement of the contact shrapnel, its It is difficult to reduce the thickness, and the thickness of the base makes the overall thickness of the whole switch larger, which does not conform to the current trend of thinning; 2. The sound part of this key switch is set on one side of the base. When the user applies pressure, The force is uneven during the pressing down process, which is easy to damage the parts, and then affects the service life of the key switch; 3. The contact is located at the lower part of the contact piece, and the response is slow and the sensitivity is poor during the pressing down process.
