The core components of a mechanical keyboard

As a core component of the mechanical keyboard, the Cherry MX mechanical axis is only representative of the mechanical axis, in addition to the Cherry ML mechanical axis, Cherry MY mechanical axis, ALPS mechanical axis, Taiwan white axis is very rare, etc. But Since the Cherry MX axis is widely recognized, if you don’t specifically mention the type of shaft, it usually refers to the Cherry MX mechanical axis. First, let’s introduce the origin and characteristics of these axes.
The Cherry MX mechanical shaft is recognized as the most classic mechanical keyboard switch. The special feel and gold contacts make it double the quality. The MX series mechanical shafts are mainly used on the keyboard. The color of the shaft cap can be distinguished. It is rare in the market of green, tea, black, red and white, and the feel is very different, which can meet the various needs of different users. From the structural point of view, the MX axis is divided into a single-column base structure and a three-column base structure, which is at the bottom of the shaft, some of which are single-column structures, and some of which are three-column structures. The latter can be guaranteed to be more stable on the PCB board. From the internal wires of the shaft, some of the internal wires of the shaft have diodes, while some of the internal wires of the shaft do not. For example, in Cherry 1965, a tea shaft with a diode wire is used, which is costly. From the design of LED lights, the MX axis can be divided into two types: lighted and unlit. The colorful DECK illuminated keyboard and some special keys that can be illuminated use this mechanical shaft. After disassembling the Cherry MX mechanical shaft, you can see its structure and components. The base and the shaft cap distinguish the type of shaft, the cap retaining card, the spring, the metal leg and the contact metal piece by its color. If it is an axis with LED lights, there are LED lights. The difference between the MX mechanical shaft mainly comes from the structure of the shaft cap and the length and number of turns of the spring. The shaft caps of the green and green shafts are unique two-layer structures, which is also a factor in the most mechanical properties of the two shafts. All the other shaft caps are of one-piece construction, but the convex portions of the switch cap that are in contact with the metal sheet are not the same, which is another major factor affecting the hand feeling except the spring.
From the pressure grams index, the green axis = tea axis < black axis < white axis, from the above introduction of the mechanical axis can be seen more directly through the pressure grams index, so in the button feel, the tea axis The green axis keyboard is the easiest, while the black axis keyboard buttons require more power and the white axis will be larger.
