Light triggered mechanical keyboard switch

Abstract

The invention relates to a light triggered mechanical keyboard switch, which comprises a keyboard fixing base, a non-contact electronic assembly and a PCB (Printed Circuit Board) arranged below the keyboard fixing base, and is characterized in that the non-contact electronic assembly comprises a light receiving component, a light emitting component, a light guiding column, a light collecting column, the light receiving component and the light emitting component are correspondingly arranged on the PCB, and the keyboard fixing base is provided with a switch body. The light triggered mechanical keyboard switch has the beneficial effects that output of switching signals is realized by adopting switching of optical signals, and the switch body is not required to be internally provided with a metal piece, so that a circumstance of poor contact between metal pieces does not appear, a circumstance of short circuit does not appear either, and the waterproofness of the switch body is realized; both the light emitting component and the light receiving component are arranged on the PCB, and the switch body is arranged on the keyboard fixing base, so that the switch body is enabled to be assembled and disassembled easily; and the light emitting component and the light guiding column serve as a light source of the switch body, thereby enabling the switch body to realize the property of light emitting on the one hand, and also providing a light source for the non-contact electronic assembly at the same time.

Description

technical field [0001] The invention relates to the field of mechanical keyboard switches, in particular to a light-triggered mechanical keyboard switch. Background technique [0002] Mechanical keyboard (English: Mechanical Keyboard) is a type of keyboard. In terms of structure, each key of the mechanical keyboard has a separate switch to control the closure. Mechanical keyboards have appeared in the early days of keyboards, and they have experienced a period of prosperity. For example, early servers were equipped with mechanical keyboards. It was soon replaced by high-quality and cheap membrane keyboards, but the mechanical keyboard has not disappeared. It has been developed as a representative of high-end products until today. The characteristics of the mechanical keyboard itself cannot be submerged, so when the mechanical keyboard experienced prosperity and decline. After that, the current situation is that more and more computer users and game players have put forward ...

AI Technical Summary

Problems solved by technology

[0004] First, both the static contact piece and the dynamic contact piece are metal pieces, which are easy to oxidize, and once oxidized, it will cause poor contact;

[0005] Second, the dustproof performance is poor. Once the dust covered on the static contact piece and the dynamic contact piece inside the mechanical switch reaches a certain level, it will affect the contact between the static contact piece and the dynamic contact piece, resulting in poor contact;

[0006] Third, the waterproof performance is poor. Once the metal sheet comes into contact with water, it will cause poor contact and even cause a short circuit of the entire keyboard;

[0007] Fourth, since each button of the mechanical keyboard has a separate switch to control the closure, in order to realize the electrical connection between the mechanical switch and the PCB board, the conventional structure is to weld the metal sheet on the PCB board by welding To achieve conduction, once one or more mechanical switches are damaged, the maintenance procedure is relatively cumbersome, and the maintenance cost is also relatively high. Many users directly use the scrapped method to dispose of the partially damaged keyboard, resulting in greater waste; therefore , the connection between the mechanical switch and the PCB board has directly affected the service life of the entire keyboard product
