Description
Technical Field
The invention relates to the technical field of key design and manufacture of mechanical keyboards, in particular to an adjustable key switch.
Background
A keyboard is a device for inputting instructions and data for operating a device, and also refers to a set of function keys (e.g., typewriter, computer keyboard) arranged through the system to operate a machine or device. The trigger shaft body related to the application can be a micro switch or a key of a game handle besides an input shaft body of a keyboard.
Along with the gradual improvement of the living standard of people in recent years, the requirements of people on keyboards are gradually improved. From the current keyboard market, keyboard architectures are divided into membrane keyboards and mechanical keyboards. Wherein the mechanical keyboard is favored by game players and IT practitioners by ITs ability to create a special feel suitable for game play or text entry.
The mechanical keyboard has the advantages of excellent hand feeling, clear classification and capability of facing different customer group demands. The service life of the mechanical keyboard is very long and is many times that of a film keyboard, and the hand feeling of the mechanical keyboard is still unchanged after the mechanical keyboard is used for a long time. This is a significant reason for many users to select a mechanical keyboard.
Structurally, each key of a mechanical keyboard has a separate switch for controlling closing, which is also referred to as a "shaft" or "shaft body", and the current Cherry MX axis can be broadly divided into a voiced paragraph axis, a unvoiced paragraph axis, and a linear axis. For example, the shaft of the sound paragraph in US4467160 is the green shaft, while the green, dark green, blue, milk shafts, etc. are springs based on the shaft body of the sound paragraph that are replaced with different pressure grams. The silent section shaft is a tea shaft, and the burnt tea shaft, the gray shaft, the white shaft and the like are springs with different pressure grams based on the shaft body of the silent section. The linear shaft is a black shaft, the red shaft, the silver shaft, the white shaft, the gray shaft and the like are all linear-based shafts, springs with different pressure gram numbers are replaced, and the silver shaft is a shaft triggering key stroke which is shorter than that of other shafts. The popular combination axis in the market is the panda axis, which advances the stroke of the pressing segment based on the combination axis of the silent segment. The paragraph sense, the trigger key stroke and the pressure gram number of each shaft are different, and the hand feeling is very different; wherein the black axis is suitable for game entertainment and the green axis is suitable for character input. According to different personal habits and purposes of consumers, different requirements are made on the hand feeling of the keyboard, but various shaft structures also bring trouble to the purchase and use of consumers to a certain extent. Some users need to input a large amount of characters in working time, amateur time can take more time in game entertainment, and the required key hand feeling span is larger, which is the extreme opposite.
Therefore, how to make a single shaft body possess multiple pressing senses and multiple triggering key processes is a technical problem to be solved.
