Description

technical field [0001] The invention relates to a computer peripheral device, in particular to a dust-proof keyboard device for a computer external input device, and belongs to the technical field of computers. Background technique [0002] The keyboard is the most common computer input device. It is widely used in microcomputers and various terminal equipment. Computer operators input various instructions and data to the computer through the keyboard to direct the work of the computer. The running status of the computer is output to the monitor. The operator can easily use the keyboard and monitor to talk to the computer, modify and edit the program, control and observe the running of the computer. The conventional keyboard has two kinds of mechanical keys and capacitive keys. In the industrial computer keyboard, there is also a keyboard with light touch membrane keys. The mechanical keyboard is the earliest structure adopted. It is generally similar to the principle of a ...

AI Technical Summary

Problems solved by technology

In theory, this kind of switch is non-contact and non-contact, the wear rate is extremely small or even negligible, and there is no hidden danger of poor contact. It has low noise, easy to control the feel, and can produce high-quality keyboards, but the process is relatively mechanical complex structure

There is also a keyboard for industrial computers that uses light-touch membrane keys for complete sealing, which is only suitable for special occasions
