At least two side walls of the outer side of the insulating base 1 are provided with a fastening portion 14 having at least one fastening block 141. An end group 15 is arranged inside the insulating base 1 as described above. The end group 15 has at least one first terminal 151, at least one second terminal 152 and a plurality of third terminals 153 that do not contact each other. One side of the first terminal 151 extends to form a first welding portion 1511 that penetrates out of the insulating base 1, and the other end of the first welding portion 1511 extends to form a first contact portion 1512 that is flat in the terminal groove 11.

On one side of the plurality of third terminals 153, third welding portions 1531 extend in the same direction towards the second welding portion 1521, and on the other side of the plurality of third welding portions 1531, third contact portions 1532 that are respectively located in the two fixing grooves 13 are bent and extended.

[0027] The trigger assembly 2 includes at least one conductive elastic sheet 21 and a pressing member 22 arranged in the accommodating groove 10. The conductive elastic sheet 21 is in a disc shape, and a pressing portion 211 that is arched is formed on the central surface of the conductive elastic sheet 21. An abutting portion 212 extends downward around the pressing portion 211. The pressing member 22 is arranged on the top of the conductive elastic sheet 21, and the pressing member 22 has a base portion 221. An elastic member 222 having a pressing portion 2221 is provided on the top surface of the base portion 221, and a pressing portion 223 that abuts against the pressing portion 211 of the conductive elastic sheet 21 protrudes from the bottom surface of the base portion 221.

[0028] At least two sides of the body 31 of the push button piece 3 protrude with reinforcing blocks 311 that are correspondingly accommodated in at least two of the pressing grooves 12. At least two sides of the body 31 corresponding to at least two of the fixing grooves 13 are recessed with hollow grooves 312.

[0029] A light-emitting element 411 is provided on the surface of the main body 41 of the lamp base 4. At least two sides of the main body 41 corresponding to at least two of the fixing grooves 13 extend with a supporting portion 42 that is located in the positioning groove 132 and abuts against the stopping surface 131. At least two docking terminals 43 that are in contact conduction with the light-emitting element 411 are arranged in the main body 41. Each of the at least two docking terminals 43 has a fourth contact portion 431 that corresponds to the end of the supporting portion 42 and extends downward to be in contact conduction with the third contact portion 1532 in the fixing groove 13.

[0030] At least two sides of the bottom of the pressing cap 5 are convexly provided with a pushing portion 51 corresponding to at least two sides of the reinforcing block 311 of the push button piece 3. A receiving groove 50 for receiving the lamp holder 4 is formed at the bottom of the pressing cap 5. Further, openings 52 for the support portions 42 to pass through are provided by cutting at least two sides of the pressing cap 5 corresponding to at least two of the support portions 42. And a pressing cap 53 for a person to press is convexly provided at the top of the pressing cap 5.

[0031] The upper cover member 6 includes a metal upper cover 61 and an insulating gasket 62. A through hole 610 is provided through the central surface of the metal upper cover 61. And fastening portions 611 with at least one fastening hole 6110 provided therein are respectively bent downwardly and extended at two sides of the metal upper cover 61. And a through hole 620 corresponding to the through hole 610 is provided through the insulating gasket 62.

[0032] Furthermore, during the assembly of the present invention, the terminal group 15 is positioned inside the insulating base 1 through injection overmolding, so that at least one of the first terminals 151, at least one of the second terminals 152, and the plurality of third terminals 153 are respectively positioned into the plurality of terminal slots 11 and at least two of the fixing slots 13. Moreover, the first contact portions 1512, the second contact portions 1522, and the plurality of third contact portions 1532 are respectively exposed at the bottom surface of the accommodating slot 10 and within at least two of the fixing slots 13. On the other side, the first welding portions 1511, the second welding portions 1521, and the plurality of third welding portions 1531 respectively penetrate through the wall surface of the insulating base 1 to the outside and are in an electrically connected state with a preset circuit board (not shown in the figure) outside. Subsequently, the trigger assembly 2, the push button piece 3, the lamp socket 4, and the pressing cap 5 are sequentially inserted into the accommodating slot 10. Thus, the abutting portion 212 at the periphery of at least one of the conductive elastic pieces 21 of the trigger assembly 2 contacts the first contact portion 1512 of at least one of the first terminals 151 to form electrical conduction. Also, the pressing portion 223 protruding from the bottom surface of the pressing member 22 contacts the surface of the pressing portion 211 of the conductive elastic piece 21. And the bottom surface of the push button piece 3 presses against the pressing portion 2221 of the elastic member 222 of the pressing member 22. Moreover, the reinforcing blocks 311 protruding from at least two sides of the main body 31 of the push button piece 3 are disposed within the pressing slots 12. The bottom surface of the main body 41 of the lamp socket 4 presses against the surface of the main body 31 of the push button piece 3. And the docking terminals 43 extending downward at the ends of the supporting portions 42 on at least two sides of the lamp socket 4 pass through the hollow slots 312 on at least two sides of the push button piece 3, so that the fourth contact portion 431 of the docking terminal 43 contacts the third contact portion 1532 within the fixing slot 13 to form contact conduction. The supporting portions 42 on at least two sides of the lamp socket 4 are positioned within the positioning slots 132 of the insulating base 1 and abut against the stopping surface 131. The pressing cap 5 covers the lamp socket 4. And the openings 52 provided by cutting at least two sides of the pressing cap 5 are higher than the supporting portions 42, and the openings 52 allow the supporting portions 42 to pass through without interference. Furthermore, the bottom surface of the pressing cap 5 can press against the surface of the push button piece 3 without contacting the lamp socket 4. And the pushing portions 51 on at least two sides of the pressing cap 5 press against the surface of the reinforcing blocks 311 of the push button piece 3. Finally, the metal upper cover 61 and the insulating gasket 62 of the upper cover member 6 are assembled onto the insulating base 1. After the pressing cap 5 sequentially passes through the through hole 620 of the insulating gasket 62 and the through hole 610 of the metal upper cover 61, at least one of the buckle holes 6110 of the buckling portion 611 is buckled onto at least one of the buckling blocks 141 of the corresponding buckling portion 14 on the outer side wall of the insulating base 1, and thus the assembly of the present invention is completed.

[0033] Please continue to refer to Figure 5 、 Figure 6As shown, they are respectively the front side view sectional drawing before pressing and the rear side view sectional drawing after pressing of the present invention. It can be clearly seen from the figure that when the present invention is actually applied, a downward force is applied to the surface of the pressing cap 53 of the pressing cap 5, so that the bottom surface of the pressing cap 5 crosses the lamp holder 4 to press the push button piece 3 downward. The pressing part 2221 of the pressing member 22 of the trigger assembly 2 is displaced downward due to the oppression of the bottom surface of the push button piece 3, and then the pressing part 223 on the bottom side of the pressing member 22 is pushed to press against the surface of the conductive elastic sheet 21 to form an arched pressing part 211 that deforms downward, so that the pressing part 211 can be electrically conducted with the second contact part 1522 of the second terminal 152, and at least one first terminal 151, at least one second terminal 152 and the plurality of third terminals 153 can generate a conduction signal through the conductive elastic sheet 21. At least two docking terminals 43 of the lamp holder 4 transmit the conduction signal to the light emitting element 411 of the lamp holder 4 after contacting the third contact part 1532 of the plurality of third terminals 153, so that the light emitting element 411 generates light and projects upward, so as to complete the action of driving the light emitting element 411 to emit light by pressing once. And when the force applied to the surface of the pressing cap 53 is released, the pressing part 211 of the conductive elastic sheet 21 will return to its original position through the elastic restoring force and be separated from the second contact part 1522 of the second terminal 152. Therefore, by applying force to the surface of the pressing cap 53 again to form an electrical switch, the switch and the light emitting element 411 can be controlled to be turned off, and the use of the present invention can be completed.

[0034] As described above, the pushing parts 51 on at least two sides of the pressing cap 5 press against the surface of the reinforcing block 311 of the push button piece 3, so as to further increase the pushing force when pressing downward, so as to avoid the ineffective switch switching due to inaccurate pressing.

[0035] Furthermore, the lamp holder 4 positions at least two docking terminals 43 inside the main body 41 through injection overmolding, and then contacts and conducts with the light emitting element 411 inside the main body 41.

[0036] In addition, the push button piece 3 and the insulating gasket 62 are made of insulating plastic, rubber or silica gel materials to avoid short circuit.

[0037] Furthermore, when a force acts on the surface of the pressing cap 5 and causes it to move, the openings 52 on at least two sides of the pressing cap 5 are provided for the at least two support portions 42 of the lamp base 4 to pass through without interference, so that when the pressing cap 5 is pushed downward, it can move downward over the lamp base 4 to prevent the at least two docking terminals 43 on at least two sides of the lamp base 4 from moving downward during pressing and rubbing against the surface of the third contact portion 1532 of the plurality of third terminals 153. Furthermore, the main feature is to prevent the at least two docking terminals 43 from being worn out and the product life being reduced due to long-term friction and sliding.

[0038] The above are only the preferred embodiments of the present invention, and thus do not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the content of the specification and drawings of the present invention should be equally included in the patent scope of the present invention.
