MECHANICAL KEYBOARD OPTICAL TYPE SWITCHES REVIEW
The article discusses the principle of operation of optical mechanical keyboards, and compares it with classical variants. It is noted that more and more areas of the technogenic sphere require precise control, due to which optics is becoming more and more in demand. The authors describe the device and the principle of operation of the optical switch. The switch is defined as an important mechanism that is located under the cap of the key. The main modern types of keyboards are highlighted: membrane, mechanical, and optical mechanical. As a result, a conclusion is made about the prospects of optical switch technology.
