[0028] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, the present invention provides a preferred embodiment of a push switch.

[0030] Combination Figures 1 to 3 The push switch includes a housing 10, a pressing member 20, a first terminal 30, a second terminal 40, a common terminal 50 and an elastic conductive component 60, wherein the elastic conductive component 60 includes a deformable fixed conductive end 61 and a movable conductive end 62, and an elastic conductive member 63 disposed between the fixed conductive end 61 and the movable conductive end 62, wherein the first terminal 30, the second terminal 40 and the common terminal 50 are all used as electrical connection terminals and are all disposed on the housing 10; the pressing member 20 is connected to the movable conductive end 62 and drives the movable conductive end 62 to move. The electrical terminal 62 moves in the housing 10; the fixed conductive terminal 61 is electrically connected to the common terminal 50; the movable conductive terminal 62 is electrically connected to the first terminal 30 at the initial position, forming a first electrical path consisting of the first terminal 30, the elastic conductive component 60 and the common terminal 50; and the movable conductive terminal 62 is pressed toward the fixed conductive terminal 61 by the pressing member 20, causing the fixed conductive terminal 61 to deform and also be electrically connected to the second terminal 40, forming a second electrical path consisting of the second terminal 40, the elastic conductive component 60 and the common terminal 50.

[0031] By providing a deformable fixed conductive end 61, a movable movable conductive end 62 and an elastic conductive member 63, the movable conductive end 62 is electrically connected to the first terminal 30 at the initial position, forming a first power path consisting of the first terminal 30, the elastic conductive component 60 and the common terminal 50; the pressing member 20 is pressed, and pressure is applied to the elastic conductive member through the movable conductive end 62 to compress it, and the movable conductive end 62 presses toward the fixed conductive end 61, so that the fixed conductive end 61 is deformed and connected to the second terminal 40, forming a second power path consisting of the second terminal 40, the elastic conductive component 60 and the common terminal 50, so that the common terminal 50 has different connection states with the first terminal 30 and the second terminal 40, and different connection states can trigger the generation of different control signals, or the continuous pressing action combination of the pressing member 20 can trigger the generation of multiple control signals, which is rich in functions and greatly expands the performance of the product. Among them, the connection state includes the common terminal 50 being electrically connected only to the first terminal 30, the common terminal 50 being electrically disconnected from both the first terminal 30 and the second terminal 40, and the common terminal 50 being electrically connected only to the second terminal 40. These three connection states can trigger the generation of different control signals, so that when the first terminal 30, the second terminal 40 and the common terminal 50 of the push switch are connected to the applied circuit, different control signals can be triggered during the process of the pressing member 20 being pressed.

[0032] Among them, reference Figure 3 Specifically, a first mounting column 11 can be provided in the housing 10, a through hole 51 can be provided at the end of the common terminal 50 and the center of the fixed conductive terminal 61, and the common terminal 50 is connected to the fixed conductive terminal 61 and is fixed on the first mounting column 11 through the through hole 51. In addition, the fixed conductive terminal 61 can be a conductive spring sheet, and its material can be brass, which has good conductivity. Of course, in other embodiments, other conductive metal materials can also be used, such as copper, aluminum and its alloys.

[0033] Furthermore, the elastic conductive member 63 is a first spring, and the two ends of the first spring are respectively connected to the fixed conductive end 61 and the movable conductive end 62. The material of the first spring can be carbon steel wire. Of course, in other embodiments, the elastic conductive member 63 can also be other elastic conductive components, such as conductive foam, etc. When the pressing member 20 is pressed, pressure is applied to the movable conductive end 62, and the movable conductive end 62 compresses the first spring and presses toward the fixed conductive end 61, so that the fixed conductive end 61 is deformed and electrically connected to the second terminal 40.

[0034] refer to Figures 4 to 6In this embodiment, the fixed conductive end 61 is a bowl-shaped structure, and its concave surface is arranged toward the movable conductive end 62, and the common terminal 50 is arranged at the bottom of the bowl-shaped structure. The movable conductive end 62 presses against the fixed conductive end 61, so that the fixed conductive end 61 of the bowl-shaped structure is deformed, and the edge is abutted and electrically connected with the second terminal 40. The fixed conductive end 61 of the bowl-shaped structure can prevent the push switch from being triggered by mistake, that is, when the pressing member 20 is accidentally pressed, the pressing force is not enough to cause the fixed conductive end 61 to deform, thereby preventing the fixed conductive end 61 from being electrically connected with the second terminal 40, thereby achieving the effect of false triggering.

[0035] refer to Figure 3 , a plurality of pressing protrusions 621 for pressing the fixed conductive end 61 to deform it are provided on the end surface of the movable conductive end 62 facing the fixed conductive end 61. Specifically, three, four or more pressing protrusions 621 can be provided on the end surface of the movable conductive end 62, and the plurality of pressing protrusions 621 are evenly or unevenly distributed. Preferably, eight pressing protrusions 621 are provided on the end surface of the movable conductive end 62, and the eight pressing protrusions 621 are evenly distributed along the circumference of the fixed conductive end 61. The eight pressing protrusions 621 can evenly press the fixed conductive end 61 to deform it and abut against the second terminal 40 to generate an electrical connection.

[0036] Further, refer to Figures 3 to 5 The movable conductive end 62 is provided with a receiving groove 622, the end of the receiving groove 622 is extended outwardly along its circumferential direction, one end of the elastic conductive member 63 is arranged in the receiving groove 622, and a plurality of the pressing protrusions 621 are arranged on the end surface of the end of the receiving groove 622 extending outwardly along its circumferential direction, and are evenly distributed along its circumference. When pressure is applied to the elastic conductive member 63, it is gradually compressed and received in the receiving groove 622, and the overall volume of the elastic conductive component 60 is smaller, which is conducive to the miniaturization of the push switch. Specifically, when the elastic conductive member 63 adopts a first spring, the first spring is compressed and received in the receiving groove 622.

[0037] refer to Figure 3 In this embodiment, the push switch further includes a second spring 70 disposed between the movable conductive end 62 and the pressing member 20. The second spring 70 acts as a buffer in the process in which the pressing member 20 is pressed to apply pressure to the movable conductive end 62 and compress the elastic conductive member 63. The material of the second spring 70 can be brass, and the first terminal 30, the second terminal 40, the common terminal 50 and the movable conductive end 62 can all be made of brass, which has good electrical conductivity. Of course, in other embodiments, these components can also be made of other conductive metal materials, such as copper, aluminum and alloys thereof.

[0038] Furthermore, combined with Figure 4 and Figure 5The interior of the pressing member 20 is a hollow structure, and the inner wall surface thereof is provided with a first limiting protrusion 21. The second spring 70 is sleeved on the movable conductive end 62 and one end thereof abuts against the first limiting protrusion 21. The material of the second spring 70 may be carbon steel wire. Specifically, the second spring 70 is sleeved on the outer wall surface of the receiving groove 622 of the movable conductive end 62, and one end abuts against the end of the receiving groove 622 of the movable conductive end 62, and the other end abuts against the first limiting protrusion 21. The second spring 70 plays a buffering role in the process of the pressing member 20 pressing the movable conductive end 62 to move.

[0039] refer to Figure 4 and Figure 5 In this embodiment, the housing 10 is provided with a second limiting protrusion 12, and the outer periphery of the pressing member 20 is provided with a third limiting protrusion 22 for limiting the pressing member 20 from being separated from the housing 10, and the third limiting protrusion 22 abuts against the second limiting protrusion 12. Under normal conditions, the third limiting protrusion 22 abuts against the second limiting protrusion 12, and after the pressing member 20 is pressed, the third limiting protrusion 22 is separated from the second limiting protrusion 12.

[0040] refer to Figure 4 The housing 10 is provided with a cavity 13 for accommodating the fixed conductive end 61 , and the end of the second terminal 40 is protrudingly disposed in the cavity 13 and is electrically connected to the fixed conductive end 61 when the fixed conductive end 61 is deformed.

[0042] Furthermore, a second mounting post 163 is also provided on the annular protrusion 16, and the first terminal 30 is provided on the second mounting post 163 and its end protrudes from the second mounting post 163, and is electrically connected to the movable conductive end 62 at the initial position. The arrangement of the first mounting groove 161, the second mounting groove 162 and the second mounting post 163 makes the components of the push switch more compact. In the initial position state, the movable conductive end 62 is electrically connected to the end of the first terminal 30, and after the pressing member 20 is pressed, the movable conductive end 62 is pressed toward the fixed conductive end 61 by the pressing member 20, disconnected from the first terminal 30, and pressed against the fixed conductive end 61 to deform it, and electrically connected to the end of the second terminal 40.

At this time, the second terminal 40 and the common terminal 50 are in a disconnected electrical connection state; the push member 20 is pressed, exerting pressure on the movable conductive end 62, compressing the elastic conductive member 63 connected to the movable conductive end 62, and the conductive connection between the movable conductive end 62 and the first terminal 30 is triggered.
