For a specific electric connection mode, a direct contact mode or a welding mode can be adopted. Specifically, the first elastic conductive via 3 may directly contact the first electrical connection region 11, or be welded on the first electrical connection region 11; similarly, the second elastic via 4 may directly contact the second electrical connection region 12, or may be soldered on the second electrical connection region 12.
When the switch main body 2 is mounted on the PCB board 1, the first elastic conductive body 3 is electrically connected to the first conductive terminal 211 and the first electrical connection area 11, respectively, so as to electrically connect the first conductive terminal 211 and the first electrical connection area 11. Because the first elastic conduction body 3 has elasticity, the first elastic conduction body 3 just abuts between the first conduction terminal 211 and the first electrical connection area 11, so that the electrical connection between the first conduction terminal 211 and the first electrical connection area 11 can be ensured, excessive force cannot be applied to the first conduction terminal 211 and the first electrical connection area 11, and particularly, the first electrical connection area 11 cannot be propped by the excessive force, and therefore, the switch conduction performance can be ensured while the repeated plugging and unplugging function is realized.
Similarly, the second elastic conductive vias 4 are electrically connected to the second conductive terminals 212 and the second electrical connection regions 12, respectively, so as to electrically connect the second conductive terminals 212 and the second electrical connection regions 12. Because the second elastic conduction body 4 has elasticity, the second elastic conduction body 4 just abuts between the second conduction terminal 212 and the second electrical connection area 12, so that the electrical connection between the second conduction terminal 212 and the second electrical connection area 12 can be ensured, excessive force cannot be applied to the second conduction terminal 212 and the second electrical connection area 12, and particularly, the second electrical connection area 12 cannot be propped by the excessive force, and therefore, the switch conduction performance can be ensured while the repeated plugging and unplugging function is realized.
In this embodiment, specifically, the first electrical connection region 11 is one of a solder paste coating and a pad, and the second electrical connection region 12 is one of a solder paste coating and a pad.
In order to prevent the first elastic conductive body 3 and the second elastic conductive body 4 from shifting or falling when the switch main body 2 is pulled out, one end of the first elastic conductive body 3 and one end of the second elastic conductive body 4 are fixed in this embodiment. Specifically, one of the first conduction terminal 211 and the PCB 1 is integrally connected to the first elastic conductive via 3, preferably, the first elastic conductive via 3 is welded or clamped on the first conduction terminal 211, or the first elastic conductive via 3 is welded on the PCB 1; one of the second conduction terminal 212 and the PCB 1 is integrally connected to the second elastic via 4, preferably, the second elastic via 4 is welded or clamped on the second conduction terminal 212, or the second elastic via 212 is welded on the PCB 1.
When the first elastic conduction body 3 is connected with the first conduction terminal 211 integrally, the first elastic conduction body 3 is separated from the PCB board 1 when the switch main body 2 is pulled out from the PCB board 1; when the first elastic conductive via 3 is connected with the PCB 1, it can be welded with the first electrical connection area 11, and when the switch main body 2 is pulled out from the PCB 1, the first elastic conductive via 3 is left on the PCB 1. Similarly, when the second elastic conduction body 4 is connected with the second conduction terminal 212 integrally, when the switch main body 2 is pulled out from the PCB board 1, the second elastic conduction body 4 is separated from the PCB board 1; when the second elastic conductive via 4 is integrally connected to the PCB 1, it can be integrally welded to the second electrical connection area 12, and when the switch main body 2 is pulled out from the PCB 1, the second elastic conductive via 4 is left on the PCB 1.

The upper part of the first spring and the upper part of the second spring are limited by the arrangement of the first cavity 22 and the second cavity 23.
In the specific structure design, the first conduction terminal 211 and the second conduction terminal 212 may be set not to penetrate through the first cavity 22 and the second cavity 23, so that when the switch main body 2 is mounted on the PCB 1, the first conduction terminal 211 does not contact with the first electrical connection area 11, the second conduction terminal 212 does not contact with the second electrical connection area 12, only the lower portion of the first spring contacts with the first electrical connection area 11 to realize electrical connection, and the lower portion of the second spring contacts with the second electrical connection area 12 to realize electrical connection.

When the switch main body 2 is installed on the PCB 1, the inverted buckle insertion blocks 241 of the two elastic inverted buckle structures 24 are inserted into the card holes 14 on the PCB 1, when the switch main body 2 is inserted, because the elastic inverted buckle structures 24 have elasticity, and under the guiding action of the lower guiding inclined planes 2422 of the guiding convex angles 242, the two elastic inverted buckle structures 24 are bent inwards, so that the inverted buckle insertion blocks 241 of the two elastic inverted buckle structures 24 are inserted into the card holes 14 and elastically reset, so that the guiding convex angles 242 of the two elastic inverted buckle structures 24 are hooked on the lower surface of the PCB 1, and then the switch main body 2 is fixed on the PCB 1.
When the switch main body 2 is pulled out upwards, because the elastic reversing structures 24 have elasticity, and under the guiding action of the upper guiding inclined planes 2421 of the guiding convex angles 242, the two elastic reversing structures 24 are bent inwards, so that the guiding convex angles 242 of the two elastic reversing structures 24 are separated from the clamping holes 14 and are not fixed on the PCB board 1, and the whole switch main body 2 is pulled out from the PCB board 1.
Through the special structural design of the elastic inverted buckle structure 24 on the switch main body 2, the switch main body 2 can be directly inserted on the PCB 1, so that the switch main body 2 is positioned and fixed on the PCB 1, and the traditional soldering tin fixing mode is replaced; meanwhile, the quick plugging operation of the switch main body 2 on the PCB board 1 can be realized, and the elastic reverse buckling structure 24 can be repeatedly used, so that the effect of quick plugging can be realized without using any tool.
The first conducting terminal 211 and the second conducting terminal 212 of the conducting assembly 21 in this embodiment can be respectively a first conducting terminal and a second conducting terminal, and the switch conducting function is realized by the contact between the first conducting terminal and the second conducting terminal, and the switch disconnecting function is realized by the separation between the first conducting terminal and the second conducting terminal.

Specifically, a third electrical connection area 13 electrically connected to the third elastic conductive via 5 is disposed on the PCB board 1, and the third electrical connection area 13 is one of a solder paste coating and a pad; one of the common terminal 213 and the PCB board 1 is integrally connected to the third elastic conductive via 5; the third elastic conductive body 5 is a third spring, the upper portion of the third spring is sleeved on the periphery of the common terminal 213, and the lower portion of the third spring is electrically connected with the third electrical connection area 13; a third cavity 25 penetrating to the lower end face of the switch main body 2 is formed in the switch main body 2, and the common terminal 213 and the upper part of the third spring are located in the third cavity 25.
As shown in fig. 5 and 6, the specific configuration of the switch main body 2 as the micro switch includes a base 10, an upper cover 20 provided on the base 10, a guide core 30 provided in the upper cover 20, a reed 40 provided in the upper cover 20 and connected between a first conduction terminal 211 and a second conduction terminal 212, and the conduction assembly 21.
When switch main body 2 is in the non-pressed state, guide core 30 does not act on reed 40, and end 401 of reed 40 is separated from second conduction terminal 212, first conduction terminal 211 is disconnected from second conduction terminal 212, that is, the switch is in the off state, as shown in fig. 1. When the guide core 30 is pressed downward, the guide core 30 acts on the spring plate 40, the end 401 of the spring plate 40 deforms and moves downward, and contacts the second conduction terminal 212, so that the first conduction terminal 211 is conducted with the second conduction terminal 212, and meanwhile, since the first conduction terminal 211 is directly electrically connected to the PCB board 1 through the first elastic conduction body 3 and the second conduction terminal 212 through the second elastic conduction body 4, the switch is in a conduction state. When the pressing of the guide core 30 is released, the guide core 30 is restored by the elastic restoring force of the spring plate 40.
It should be noted that the specific structure of the switch main body 2 is not limited to the above description, nor to the structure shown in the drawings.
