The way that the through terminal is directly welded on the PCB board enables the first through terminal and the second through terminal to have the function of switching electrical conduction, and also have the ability to repeatedly and quickly insert and pull out. When the main body of the switch is defective or damaged, the main body of the switch can be directly pulled out for repair or replacement, which is convenient and quick to repair and replace.

A large force resists the first electrical connection area and the second electrical connection area, so the switch can be turned on while realizing the function of repeated plugging and unplugging.
(3)通过由开关主体上弹性倒扣结构的特殊结构设计,可以将开关主体直接插到PCB板上,实现将开关主体定位固定于PCB板上,从而代替传统焊锡固定的方式;同时,可实现开关主体在PCB板上的快速插拔操作,而且,弹性倒扣结构可以反复使用,可以在不使用任何工具的条件下,实现快速插板的效果。(3) Through the special structural design of the elastic inverted structure on the switch body, the switch body can be directly inserted into the PCB board, so that the switch body can be positioned and fixed on the PCB board, thereby replacing the traditional soldering method; The quick plug-in operation of the switch body on the PCB board is realized, and the elastic inverted buckle structure can be used repeatedly, and the effect of quick plug-in can be realized without using any tools.

Due to the elasticity of the second elastic conducting body 4 , the second elastic conducting body 4 just abuts between the second conducting terminal 212 and the second electrical connection area 12 , which not only ensures that the second conducting terminal 212 and The electrical connection between the second electrical connection areas 12 will not exert excessive force on the second conductive terminal 212 and the second electrical connection area 12 , and especially will not withstand the The two electrical connection regions 12, therefore, while realizing the function of repeated plugging and unplugging, the switch conduction performance can also be ensured.
