What is a mechanical keyboard? What other keyboards are there besides mechanical keyboards? What are the red, black, tea, green and white axes? What is the difference?

mechanical keyboard, and can not be determined from the feel, sound and other subjective feelings, or from the structure to define the mechanical keyboard, each key has a separate Switch (that is, the switch) to control the closure of the switch is also known as the "axis". Although the Cherry mechanical shaft is the most famous, but in addition to it, the market has other brands of mechanical shafts, including the early Nissan ALPS shaft, Taiwan ALPS simple shaft, Taiwan white shaft and so on. In addition to mechanical keyboards and membrane keyboards, that is, we commonly used, and then capacitive keyboards, more expensive than the mechanical. full name without contact electrostatic capacitive keyboard (Capacitive?0?2Keyboard) This type of keyboard is rare and expensive, featuring a green circuit board you will see a piece of green, on the top of the circuit, but the keys do not have any mechanical components "welded" in the corresponding circuit board. The tactile sensation is created by rubber and spring, etc. The switch's on and off is determined by electrostatic capacitance induction, so it is rare to see a high level of technical skill to make it accurate. The well-known capacitive keyboards on the market today are Topre's Realforce series keyboards and Fujitsu's Happy ?0?2Hacking series keyboards look at the picture for an explanation of the axes.
