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 and close. This switch is also called “axis”. The classification of switches, mechanical keyboards can be divided into traditional brown switches, green switches, white switches, black switches, red switches, and Romer-G and optical switches. It is precisely because each button is composed of an independent micro-motion, so the button has a strong sense of paragraph, resulting in a special feel suitable for game entertainment, so it is usually used as a relatively expensive game peripheral.
The plastic (resin) is a terpolymer of acrylonitrile, butadiene and styrene (A for acrylonitrile, B for butadiene, S for styrene). It should be a widely used material in the PC industry, chassis panels, monitor shells, keyboards and mice, etc., it can be seen almost everywhere. It has the characteristics of tasteless and non-toxic. It can be used at a low temperature of minus 40 degrees Celsius, the melting temperature is as high as 217 degrees Celsius (the heat distortion temperature is 93-118 degrees Celsius), and it has strong impact resistance and is not easy to deform. It has good insulation and is not easily affected by humidity. and frequency effects.
There are many keycaps in all materials. Of course, the main reason is that the craftsmanship is sophisticated and the price is cheap. You can see ABS data keycaps from ordinary keyboards of tens of yuan to goods of thousands of yuan. ABS keycaps have various colors and can be made translucent to meet the needs of backlighting, which is unmatched by other materials. The keycap made of this material is softer than other materials, not very hard and gentle to the touch, and has a certain ability to resist oil, but it is not as good as POM and
