The metal dome 4 is supported on the dome slot 14 by the dome legs 42, and the top of the metal dome 4 abuts against the bottom of the key 2. By setting the metal dome 4 and pressing the metal dome 4, the metal dome 4 and the dome legs 42 form a downward pressure deformation, the metal dome abuts against the first pin and the second pin to conduct, and the metal dome 4 is released, and the metal dome automatically restores its deformation.

[0038] Specifically, as shown in the figure, the lamp slot 15 is provided in the middle position of the shrapnel slot 14.

By setting the above - mentioned structures of the first pin 31 and the second pin 32, during installation, the four shrapnel feet of the metal shrapnel are respectively supported in the four connecting parts. One of the shrapnel feet remains in conductive contact with the first bending arm 311, and the remaining three shrapnel feet are only in a supporting state. By setting the stable connection platform 321 and the three conductive bumps 322 arranged on its top surface, when pressing the metal shrapnel, when the shrapnel foot deforms downward under pressure, it comes into contact with one or more of the conductive bumps 322, and can form conduction with the first pin 31. Therefore, the user does not need to apply a vertical force to activate the tactile switch, thus increasing the stability of the tactile switch.

[0039] Specifically, as shown in the figure, the inner ends of the third pin 33 and the fourth pin 34 are both formed with second bending arms 35. The two second bending arms 35 are respectively electrically connected to the positive and negative electrodes of the surface - mounted LED lamp 5, and the positive and negative electrodes of the surface - mounted LED lamp 5 are located on the same side.

By adding the bottom sleeve 8, the first pin, the second pin, the third pin, and the fourth pin are set to limit the positioning, and the user can directly perform the Haba welding on the pin 3 on one side of the bottom sleeve 8, which further increases the stability of the welding. At the same time, the bottom sleeve can be used as a plug-in mechanism. In addition to the welding method, the bottom sleeve can also be directly inserted downward to form a plug-in guide connection with the docking component, which further increases the convenience of use.
