[0002] With the continuous upgrading of various electronic product technologies, people have more and more requirements for the usage functions of electronic products.

[0040] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following details the specific implementation manners of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0041] Embodiment 1:

[0042] Please refer to Figures 1 to 5, this embodiment provides a single-pole double-throw push-button switch, which includes a base 1 and an upper cover 2. The upper cover 2 is covered on the base 1 to form an accommodation cavity. In the accommodation cavity, a guide core 3 and an elastic member 4 located below the guide core 3 are respectively arranged. An opening 21 for the upper end of the guide core 3 to pass through is provided on the upper cover 2. The single-pole double-throw push-button switch of this embodiment further includes a single-pole double-throw conduction component 5 arranged in the accommodation cavity and on the side of the guide core 3, and a pushing component 6 arranged in the accommodation cavity and driven by the guide core 3 to generate displacement. Among them, the single-pole double-throw conduction component 5 includes a static contact structure 51 and a moving contact structure 52 arranged oppositely. Specifically, as Figure 5 shown, the static contact structure 51 is mainly composed of an upper static contact 511 and a lower static contact 512. An upper static contact point 5110 is arranged on the upper static contact 511, and a lower static contact point 5120 is arranged on the lower static contact 512; specifically, as Figure 4 shown, an upper moving contact point 5221 corresponding to the upper static contact point 5110 and a lower moving contact point 5231 corresponding to the lower static contact point 5120 are respectively arranged on the moving contact structure 52; the pushing component 6 faces the moving contact structure 52.

[0043] In this embodiment, as Figure 4 shown, the moving contact structure 52 is mainly composed of a moving contact body 521, an upper elastic piece 522 and a lower elastic piece 523 respectively bent from one end of the moving contact body 521 toward the side of the static contact structure 51, and a moving contact terminal 524 connected to the moving contact body 521. Among them, the upper moving contact point 5221 is arranged on the side surface of the upper elastic piece 522, the lower moving contact point 5231 is arranged on the side surface of the lower elastic piece 523, the moving contact terminal 524 is inserted into the base 1 and extends to the outside of the base 1, and is electrically connected to the PCB board arranged outside the base 1. Specifically, the moving contact terminal 524 can be directly welded to the PCB board.

[0044] In order for the pushing component 6 to better push the upper elastic piece 522 and the lower elastic piece 523, in this embodiment, the end parts of the upper elastic piece 522 and the lower elastic piece 523 respectively have a protruding part (5220, 5230), and the protruding part (5220, 5230) faces the pushing component 6. When the pushing component 6 pushes the upper elastic piece 522 and the lower elastic piece 523 to cause the upper elastic piece 522 and the lower elastic piece 523 to deform, the pushing component 6 directly contacts the protruding part (5220, 5230) and applies an action to the protruding part (5220, 5230).

[0045] In this embodiment, as Figure 5As shown, the lower stationary contact piece 512 mainly consists of a lower stationary contact piece body 5121 and a lower stationary contact piece terminal 5122 connected to the lower stationary contact piece body 5121. Among them, the lower stationary contact 5120 is arranged on the side surface of the lower stationary contact piece body 5121, and the lower stationary contact piece terminal 5122 is inserted into the base 1 and extends to the outside of the base 1. At the same time, the upper stationary contact piece 511 mainly consists of an upper stationary contact piece body 5111, an upper stationary contact piece extension 5112 connected to the upper stationary contact piece body 5111 and extending above the lower stationary contact piece body 5121, and an upper stationary contact piece terminal 5113 connected to the upper stationary contact piece body 5111. Among them, the upper stationary contact 5110 is arranged on the side surface of the upper stationary contact piece extension 5112, and the upper stationary contact piece terminal 5113 is inserted into the base 1 and extends to the outside of the base 1. The lower stationary contact piece terminal 5122 and the upper stationary contact piece terminal 5113 are respectively electrically connected to the PCB board arranged outside the base 1. Specifically, the lower stationary contact piece terminal 5122 and the upper stationary contact piece terminal 5113 can be directly welded to the PCB board.

[0046] In this embodiment, as Figure 9 shown, a conduction component slot 11 for inserting the stationary contact piece structure 51 and the moving contact piece structure 52, a guide core moving slot 12 for the up and down movement of the guide core 3, and a pushing component moving slot 13 that communicates between the conduction component slot 11 and the guide core moving slot 12 and into which the pushing component 6 is inserted and can move are respectively formed on the base 1.

[0047] In this embodiment, as Figure 3 、 Figure 6 、 Figure 7 and Figure 10 shown, the pushing component 6 includes an upper piston 61 located between the guide core 3 and the upper elastic piece 522, and a lower piston 62 arranged below the upper piston 61 and located between the guide core 3 and the lower elastic piece 523. Both the upper piston 61 and the lower piston 62 are inserted into the pushing component moving slot 13. At the same time, as Figure 8 shown, a pushing convex block 31 for pushing the upper piston 61 and the lower piston 62 is arranged on the side edge of the guide core 3. Specifically, the upper part of the pushing convex block 31 has an upper inclined surface 311, and the lower part has a lower inclined surface 312.

[0048] In this embodiment, the upper piston 61 and the lower piston 62 are inserted into the pushing component moving slot 13. Preferably, the pushing component moving slot 13 is filled. Therefore, liquid and dust will not enter the conduction component slot 11 from the pushing component moving slot 13. At the same time, the upper piston 61 and the lower piston 62 will only move horizontally under the push of the pushing convex block 31 and will not move longitudinally.

[0049] Specifically, as Figure 6As shown, the upper piston 61 is mainly composed of an upper piston body 611 and an upper push limiter 612 connected to the end surface of the upper piston body 611 and located on the side of the upper spring sheet 522. Figure 7 As shown, the lower piston 62 is mainly composed of a lower piston body 621, a lower push limit portion 622 connected to the end surface of the lower piston body 621 and located on the side of the lower spring sheet 523, and a support portion 623 connected to the upper end surface of the lower piston body 621 and facing the upper piston body 611; the upper push limit portion 612 and the lower push limit portion 622 are both located in the conductive component slot 11, and the lengths of the upper push limit portion 612 and the lower push limit portion 622 are both greater than the width of the push component active slot 13, thereby ensuring that the upper push limit portion 612 and the lower push limit portion 622 will not enter the push component active slot 13, and the upper piston 61 and the lower piston 62 will not separate from the push component active slot 13 during the lateral movement. Figure 3 shown.

[0050] At the same time, an arc portion (6111, 6211) is respectively provided on the end surface of the upper piston body 611 and the lower piston body 621 close to the pushing protrusion 31. When the pushing protrusion 31 pushes the upper piston 61 and the lower piston 62, the pushing protrusion 31 directly contacts the arc portion (6111, 6211) and applies a lateral force to the arc portion (6111, 6211).

[0051] In this embodiment, if Figure 9 As shown, a guide column 14 is protruded upward in the guide core movable groove 12, a guide plug hole 141 is recessed downward at the upper end of the guide column 14, and a guide shaft 32 inserted into the guide plug hole 141 is protruded downward at the lower end of the guide core 3, as shown in FIG. Figure 8 The elastic member 4 is a spring 4 ', the spring 4 'is sleeved around the guide column 14, and the upper end of the spring 4 'extends to the lower end surface of the guide core 3, such as Figure 13 When the guide core 3 is pressed downward, the guide core 3 moves up and down along the guide column 14, and the spring 4' provides a pressing restoring force.

[0052] When the key switch of this embodiment is in the natural state, Figure 12 and Figure 13As shown, the pushing bump 31 on the guide core 3 has pushed the upper piston 61 in the direction of the moving piece structure 52 (to the right), so the upper piston 61 pushes the upper elastic piece 522 of the moving piece structure 52 to the right, causing the upper moving contact 5221 on the upper elastic piece 522 to separate from the upper static contact 5110 on the upper static piece 511. Then, the moving piece structure 52 and the upper static piece 511 are in an open state, that is, an open circuit state. The pushing bump 31 on the guide core 3 has not yet contacted the lower piston 62 and has not exerted a force on the lower piston 62. Therefore, the lower piston 62 has not exerted a force on the lower elastic piece 523 of the moving piece structure 52 either. Then, the lower moving contact 5231 on the lower elastic piece 523 contacts the lower static contact 5120 on the lower static piece 512, and the moving piece structure 52 and the lower static piece 512 are in a closed conduction state.

[0053] When the guide core 3 is pressed downward, as Figure 14 shown in Figure 15 the figure, the guide core 3 moves downward, and the pushing bump 31 on the guide core 3 moves downward accordingly. During the downward movement of the pushing bump 31, the upper piston 61 moves to the left along the upper inclined surface 311 of the pushing bump 31 under the action of the elastic restoring force of the upper elastic piece 522 until the upper moving contact 5221 on the upper elastic piece 522 contacts the upper static contact 5110 on the upper static piece 511. That is, the moving piece structure 52 and the upper static piece 511 are in a closed conduction state. The guide core 3 continues to move downward, causing the lower inclined surface 312 of the pushing bump 31 to contact the lower piston 62. During the continuous downward movement of the guide core 3, the lower piston 62 moves along the lower inclined surface 312 and moves to the right due to the force exerted to the right. Then, the lower piston 62 pushes the lower elastic piece 523 of the moving piece structure 52 to the right, causing the lower moving contact 5231 on the lower elastic piece 523 to separate from the lower static contact 5120 on the lower static piece 512. Then, the moving piece structure and the lower static piece 512 are in an open state, that is, an open circuit state.

[0054] As described above, when the guide core 3 is pressed downward, the moving piece structure 52 and the upper static piece 511 are in a closed and conducting state, and the moving piece structure and the lower static piece 512 are in a disconnected state. In this state, the key switch is defined as being in a conducting state. When the guide core 3 is not pressed and the key switch is in its natural state, the moving piece structure 52 and the upper static piece 511 are in a disconnected state, and the moving piece structure 52 and the lower static piece 512 are in a closed and conducting state. Correspondingly, in this state, the key switch is defined as being in a disconnected state. When the key switch is in its natural state, since the moving piece structure 52 and the lower static piece 512 are also in a closed and conducting state, this state can be defined for other different functions to control other actions and achieve other functions. For example, it can be defined as lighting the lights around the key switch or lighting the LED lamp inside the key switch. That is, when the key switch is not pressed, since the moving piece structure 52 and the lower static piece 512 are in a closed and conducting state, the lights around the key switch or the LED lamp inside the key switch are lit, thus realizing the control of the lights, facilitating the user to clearly see the position of the key switch and playing an indicating role. After the key switch is pressed downward, the lights go out. Of course, other function definitions can also be made.

[0055] Compared with the existing key switch, in this embodiment, a new state of lower conduction and upper disconnection is given to the key switch in its natural non-pressed state. In this state, not only can the disconnection function of the key switch be realized, but also the control of other functions can be achieved. Therefore, the key switch in this embodiment adopts a single-pole double-throw conduction component 5, which can not only realize the control of the conduction and disconnection functions of the key switch, but also realize the control of other functions, such as lighting control, that is, it realizes the function of one switch with dual control, endows the key switch with one more function, meets more needs of users, and improves the user experience.

[0056] To improve the waterproof and dustproof performance of the key switch, as Figure 10 shown in Figure 11 , a dustproof cover 7 is covered on the conduction component slot 11 and the push component moving slot 13. The conduction component slot 11 and the push component moving slot 13 are covered by the dustproof cover 7 to prevent liquid and dust from entering and affecting the working performance of the single-pole double-throw conduction component 5, thereby ensuring the working performance of the single-pole double-throw conduction component 5 and increasing its service life.

[0057] To improve the pressing feel and sound sense, as Figure 11As shown in the figure, in this embodiment, a torsion spring 8 is provided on the base 1, and a pressing bump 33 for elastically moving the torsion spring 8 is provided on the side of the guide core 3. During the process of pressing the guide core 3 downward, the pressing bump 33 on the guide core 3 moves downward accordingly. The pressing bump 33 presses the elastic part 81 of the torsion spring 8 downward, and the elastic part 81 moves downward. When the elastic part 81 moves downward and touches the guiding inclined surface 10 on the base 1, it slides outward along the guiding inclined surface 10 until the elastic part 81 disengages from the pressing bump 33. At this time, the user will feel that the pressing force significantly decreases, thus generating a tactile sensation. At the same time, the elastic part 81 rebounds and resets, hitting the upper cover 2 to produce a sound, enhancing the acoustic sensation.

[0058] Embodiment Two:

[0059] As Figures 16 to 18 shown in the figure, the main difference between this embodiment and Embodiment One is that the pushing component 6 in this embodiment is a push rod 60 connected to the side of the guide core 3 and movable within the pushing component moving slot 13. The end of the push rod 60 extends to the sides of the upper elastic sheet 522 and the lower elastic sheet 523. And this embodiment does not include the upper piston 61 and the lower piston 62, and there is no need to provide a pushing bump 31 on the side of the guide core 3.

[0060] When the key switch in this embodiment is in the natural state, as Figure 19 shown in the figure, the push rod 60 on the guide core 3 has already pushed the upper elastic sheet 522 of the moving sheet structure 52 to the right, causing the upper moving contact 5221 on the upper elastic sheet 522 to separate from the upper static contact 5110 on the upper static sheet 511. Then, the moving sheet structure 52 and the upper static sheet 511 are in an open state, that is, an open - circuit state. And the push rod 60 on the guide core 3 has not exerted a force on the lower elastic sheet 523 of the moving sheet structure 52. Then, the lower moving contact 5231 on the lower elastic sheet 523 is in contact with the lower static contact 5120 on the lower static sheet 512. Then, the moving sheet structure 52 and the lower static sheet 512 are in a closed - conduction state.

[0061] When pressing the guide core 3 downward, as Figure 20 shown in the figure, the guide core 3 moves downward, and the push rod 60 on the guide core 3 moves downward accordingly. When the push rod 60 moves downward and disengages from the upper elastic sheet 522, the upper elastic sheet 522 rebounds and resets under the action of its own elastic restoring force. Then, the upper moving contact 5221 on the upper elastic sheet 522 is in contact with the upper static contact 5110 on the upper static sheet 511. That is, the moving sheet structure 52 and the upper static sheet 511 are in a closed - conduction state. The guide core 3 continues to move downward, causing the push rod 60 to contact the lower elastic sheet 523 of the moving sheet structure 52 and push the lower elastic sheet 523 to the right. The lower elastic sheet 523 moves to the right due to the applied right - ward force, causing the lower moving contact 5231 on the lower elastic sheet 523 to separate from the lower static contact 5120 on the lower static sheet 512. Then, the moving sheet structure and the lower static sheet 512 are in an open state, that is, an open - circuit state.

[0062] The functions implemented in this embodiment are the same as those in Embodiment 1. It can not only control the on and off functions of the push-button switch, but also control other functions, such as lighting control, that is, it realizes the function of one switch with dual control, endows the push-button switch with an additional function, meets more needs of users, and improves the user experience.

[0063] It should be noted here that for the setting of the lighting (LED lamp), the combination of the LED lamp and the PCB board, and the combination of the push-button switch and the PCB board in the above Embodiment 1 and Embodiment 2 of the present invention are all conventional technologies in the art and not the focus of the present invention. The present invention only details the technical features of the push-button switch, provides a new state and a new control method for the push-button switch, and combines the common general knowledge and conventional technologies in the art to define the functions of this state.

[0064] The above description is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as those in the above embodiments of the present invention are all within the protection scope of the present invention.
