What is the difference between a mechanical keyboard and a normal keyboard?

At present, most of the mechanical keyboards on the market are connected by soldering tin, which is commonly known as "welding keyboard". The shaft body is welded on the PCB board. The advantage is that the connection is stable. That is:

During the long-term use of this type of keyboard, if some shafts are damaged or you want to experience a different feel, you need to use tools such as electric soldering iron to disassemble the keyboard and then "de-solder and de-solder" the internal circuit board. It is not particularly friendly to most friends who have poor hands-on ability or feel that it is too troublesome to do it by themselves.

However, the hot-swappable keyboard just solves the pain point of players wanting to "easily switch axes". This type of keyboard is more common in the customization circle at first; players who want to experience the feel of different axes can keep the keyboard disconnected In some cases, the shaft body can be directly inserted and replaced through the shaft puller, and there is no need to disassemble it, which is troublesome and time-consuming.

However, compared with soldered keyboards, the connection of hot-swappable keyboards is relatively unstable. Poor contact may occur due to oxidation of copper sheets after frequent plugging and unplugging. Poor contact occurs when the body pins are bent, but for the latter, the player only needs to re-plug and straighten the shaft body pins to solve it. In terms of playability, the hot-swappable keyboard has to be said to be even better...
