[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1 This embodiment provides a switch with an operating mechanism, as shown in the attached diagram. Figures 1-11 As shown, it includes: The housing 18 has a receiving cavity 181.

[0036] An operating mechanism is housed in a receiving cavity 181. The operating mechanism includes an electromagnetic component, a transmission component 19, a rotating component 11 connected to the moving contact 15, and a torsion spring 20. The electromagnetic component includes two symmetrically arranged electromagnets 21 and a moving iron core 22. The two electromagnets 21 drive the moving iron core 22 to reciprocate along a first direction, which is the length direction of the housing 18. In this embodiment, the left-right direction is used as an example, meaning the moving iron core 22 can move to the left or right under the action of the two electromagnets 21, forming a reciprocating motion on both sides. The transmission component 19 rotates relative to the housing 18; the transmission component 19 can rotate. During its movement, the moving iron core 22 drives one end of the transmission component 19, and the other end of the transmission component 19 drives the rotating component 11. Here, one end of the transmission component 19 engages with the moving iron core 22, and the other end engages with the rotating component 11, creating a transmission effect between the moving iron core 22 and the rotating component 11. That is, when the electromagnet 21 drives the moving iron core 22, the moving iron core 22 drives one end of the transmission component 19, achieving the rotation of the transmission component 19. The other end of the transmission component 19 drives the rotating component 11, ultimately achieving the rotation of the moving contact 15. One end of the torsion spring 20 is connected to the transmission component 19, and the other end of the torsion spring 20 is connected to the housing 18. During the rotation of the transmission component 19, the torsion spring 20 serves to store and release energy, accelerating the rotation of the transmission component 19. By setting the transmission component 19, the transmission ratio can be adjusted through multi-stage transmission to reduce the torque, thereby controlling the volume of the electromagnet 21. Secondly, by setting the torsion spring 20, the torsion spring 20 can be fitted and housed in the receiving cavity 181, reducing the thickness space occupied by the torsion spring 20. At the same time, the torsion spring 20 can better achieve the energy storage and release effect. Moreover, the multi-stage transmission makes the transmission more stable.

[0037] Specifically, as shown in the attached document Figures 1-4As shown, one of the transmission member 19 and the inner wall of the receiving cavity 181 is provided with a rotating shaft portion 23, and the other of the transmission member 19 and the inner wall of the receiving cavity 181 is provided with a rotating shaft hole 24 that mates with the rotating shaft portion 23. The mate between the rotating shaft portion 23 and the rotating shaft hole 24 creates the effect of rotation of the transmission member 19. When the transmission member 19 is provided with a rotating shaft portion 23, the inner wall of the receiving cavity 181 is provided with a rotating shaft hole 24; conversely, when the transmission member 19 is provided with a rotating shaft hole 24, the inner wall of the receiving cavity 181 is provided with a rotating shaft portion 23. In this embodiment, the example of the transmission member 19 being provided with a rotating shaft portion 23 and the inner wall of the receiving cavity 181 being provided with a rotating shaft hole 24 is described. Furthermore, it should be noted that the rotating shaft hole 24 is specifically provided on the inner wall of the driving cavity 1811.

[0038] Specifically, as shown in the attached document Figures 1-4 As shown, the transmission component 19 is a cam structure. The length from the center position of the rotating shaft 23 to the first protrusion 191 and the length from the center position of the rotating shaft 23 to the position where it meshes with the rotating component 11 can be adjusted according to actual needs. In this embodiment, the length from the center position of the rotating shaft 23 to the first protrusion 191 is greater than the length from the center position of the rotating shaft 23 to the position where it meshes with the rotating component 11, thus forming a lever effect.

[0039] Specifically, as shown in the attached document Figures 1-4 As shown, the moving iron core 22 includes two ends 221 and a middle portion 222. The two ends of the middle portion 222 are connected to the two ends 221 respectively. Two stepped surfaces 223 are formed between the middle portion 222 and the two ends 221. In this embodiment, the two ends 221 have the same diameter, and the diameter of the two ends 221 is larger than the diameter of the middle portion 222, thus creating the effect of the stepped surfaces 223. The transmission member 19 is provided with a first protrusion 191 extending towards one side of the moving iron core 22. The first protrusion 191 is located on the movement trajectory of the two stepped surfaces 223. The rotation of the transmission member 19 is achieved by the driving effect of the first protrusion 191 formed by the stepped surfaces 223.

[0040] Specifically, as shown in the attached document Figures 1-4 As shown, the receiving cavity 181 is provided with a first groove 1813, and the transmission component 19 is partially embedded in the first groove 1813. Here, the first groove 1813 is located on the inner wall of the driving cavity 1811. Through the digging structure, the transmission component 19 is fixed. Secondly, the thickness of the inner wall of the driving cavity 1811 can also be reduced, thereby adjusting the thickness of the entire housing 18.

[0041] Specifically, as shown in the attached document Figures 1-4As shown, the inner wall of the receiving cavity 181 is provided with a protrusion 1814, and the protrusion 1814 is provided with a first insertion hole 1815. The transmission component 19 is provided with a second protrusion 192, and the second protrusion 192 is provided with a second insertion hole 193. One end of the torsion spring 20 is inserted into the first insertion hole 1815, and the other end of the torsion spring 20 is inserted into the second insertion hole 193. Both the first insertion hole 1815 and the second insertion hole 193 achieve the fixing effect of the torsion spring 20. In this embodiment, the central area of ​​the torsion spring 20 is limited by the thickness of the driving cavity 1811. Alternatively, a fixed shaft can be provided so that the central area of ​​the torsion spring 20 is sleeved on the fixed shaft to achieve the effect of limiting and fixing.

[0042] Specifically, the second protrusion 192 extends toward the side of the torsion spring 20.

[0043] Specifically, the transmission member 19 and the rotating member 11 are gear driven. Here, the rotating member 11 is provided with a gear section, and the area where the transmission member 19 and the rotating member 11 cooperate is a sector gear structure, thereby realizing the meshing between the two.

[0044] Specifically, as shown in the attached document Figures 1-4 As shown, the operating mechanism also includes a handle 25, which is gear-driven to the rotating member 11. One end of the handle 25 is located outside the housing 18, and the end of the handle 25 extending into the receiving cavity 181 is also a sector gear structure, thereby achieving meshing with the rotating member 11 to form a gear drive. The operating mechanism can be manual or electric, and those skilled in the art can adjust it according to actual needs.

[0045] Specifically, as shown in the attached document Figures 1-4 As shown, the receiving cavity 181 includes a driving cavity 1811 and a first chamber 1812. The driving cavity 1811 and the first chamber 1812 are formed by assembling three components of the housing 18. The three components are joined along the thickness direction. The component on one side and the component in the middle form the driving cavity 1811, and the component on the other side and the component in the middle form the first chamber 1812. The lower ends of the driving cavity 1811 and the first chamber 1812 are connected. The electromagnetic component is located in the first chamber 1812. The first protrusion 191 extends through the driving cavity 1811 to the first chamber 1812, realizing the transmission between the first protrusion 191 and the stepped surface 223. The transmission component 19 is housed in the driving cavity 1811, and the handle 25 passes through the top surface of the driving cavity 1811 into the driving cavity 1811. The gear portion of the rotating component 11 is located within the drive cavity 1811. One end of the rotating component 11 extends into the first chamber 1812 and connects with the rotating component 11 located in the first chamber 1812, achieving a transmission effect between the two rotating components 11. A moving contact 15 is fixed to the rotating component 11 located in the first chamber 1812. The other end of the rotating component 11 extends away from the first chamber 1812, and a moving contact 15 is also fixed to this end.

[0046] Specifically, as shown in the attached document Figures 5-11 As shown, the assembly also includes a first stationary contact 12, a second stationary contact 13, a third stationary contact 14, and an elastic member 16. The rotating member 11 has a cavity 111 with a side opening 112, which is a radial opening. The two ends of the moving contact 15 are a first contact head 151 and a second contact head 152, respectively. The moving contact 15 extends into the cavity 111, and the portion of the moving contact 15 extending into the cavity 111 has a through groove 153 that passes through the moving contact 15 vertically. After the moving contact 15 and the rotating member 11 are assembled, the channel is located within the cavity 111. The moving contact 15 is electrically connected to the third stationary contact 14. The elastic element 16 is located within the through groove 153. Both ends of the elastic element 16 abut against the inner wall of the through groove 153, and a portion of the elastic element 16 extends beyond the through groove 153. Specifically, the height direction of the rotating element 11 refers to its axial direction. The elastic element 16 can extend upwards, downwards, or both. The portion of the elastic element 16 extending beyond the through groove 153 lies on the movement trajectory of the inner wall of the cavity 111. That is, when the rotating element 11 rotates, the inner wall of the cavity 111 abuts against the elastic element 16, compressing it and creating contact pressure. In this embodiment, in a set of switches with an operating mechanism, the number of elastic elements 16 is only one.

[0047] The rotation center line of the moving contact 15 and the rotation center line of the rotating member 11 are collinear. The moving contact 15 and the rotating member 11 rotate coaxially and relative to each other. The rotating member 11 drives the moving contact 15 to rotate. When the moving contact 15 is stationary, the rotating member 11 can continue to rotate.

[0048] In the first state, during the rotation of the rotating member 11, the moving contact 15 is driven to rotate, and the rotating member 11 presses against the elastic member 16, so that the first stationary contact 12 and the first contact head 151 are in contact. When the first stationary contact 12 and the first contact head 151 are in contact, the rotating member 11 continues to rotate, so as to press against the elastic member 16. The elastic member 16 applies pressure to the first contact head 151 to form contact pressure, thereby ensuring the stability of the electrical connection between the first stationary contact 12 and the first contact head 151.

[0049] In the second state, as the rotating member 11 rotates, it drives the moving contact 15 to rotate, and the rotating member 11 presses against the elastic member 16, so that the second stationary contact 13 and the second contact head 152 abut against each other. When the second stationary contact 13 and the second contact head 152 abut against each other, the rotating member 11 continues to rotate, achieving the effect of pressing against the elastic member 16. The elastic member 16 applies pressure to the second contact head 152, forming contact pressure, thereby ensuring the stability of the electrical connection between the second stationary contact 13 and the second contact head 152. With this structural arrangement, the contact pressure effect can be achieved through a single elastic member 16. This structural arrangement is simple and easier to install.

[0050] Specifically, as shown in the attached document Figures 5-11 As shown, the inner wall of the cavity 111 is provided with a second groove 113. The second groove 113 is located near the side opening 112 and communicates with the side opening. The two side walls of the second groove 113 abut against the two ends of the elastic member 16. When the elastic member 16 is fixed in the through groove 153, the two ends of its portion extending beyond the through groove 153 abut against the two ends of the second groove 113, creating the effect of the rotating member 11 driving the elastic member 16. The provision of the second groove 113 further improves the cooperation effect between the cavity 111 and the elastic member 16, allowing the rotating member 11 to apply pressure to the elastic member 16 during rotation.

[0051] Specifically, as shown in the attached document Figures 5-11 As shown, there are two second grooves 113, which are symmetrically arranged relative to the moving contact 15. The two second grooves 113 are arranged vertically symmetrically. When the moving contact 15 is inserted into the cavity 111, one second groove 113 is located above the moving contact 15, and the other second groove 113 is located below the moving contact 15. When the elastic member 16 is located in the through groove 153, the elastic member 16 extends upwards and downwards beyond the through groove 153. At this time, the two ends of the portion of the elastic member 16 extending upwards abut against the two ends of the upper second groove 113, and the two ends of the portion of the elastic member 16 extending downwards abut against the two ends of the lower second groove 113. The symmetrical arrangement of the two second grooves 113 creates axial balance, further improving overall stability. Alternatively, the number of second grooves 113 can also be one; those skilled in the art can adjust this according to actual needs.

[0052] Specifically, the elastic element 16 is a spring. Preferably, the elastic element 16 is a straight spring. However, those skilled in the art can adjust the structure of the elastic element 16 according to actual needs, and it can be changed to a torsion spring 20 or other structures. It should also be noted that the size and stiffness of the spring can be adjusted according to actual needs.

[0053] Specifically, as shown in the attached document Figures 5-11As shown, the first stationary contact 12 and the second stationary contact 13 are arranged vertically parallel to each other and face the same direction. In this embodiment, the first stationary contact 12 is located above the second stationary contact 13. The area where the first stationary contact 12 and the moving contact 15 cooperate is vertically arranged, thus forming an effect facing to the left. The moving contact 15 rotates to the left of the first stationary contact 12, forming an electrical connection between the moving contact 15 and the first stationary contact 12. The second stationary contact 13 is located below the first stationary contact 12. The area where the second stationary contact 13 and the moving contact 15 cooperate is also vertically arranged, also forming an effect facing to the left. The moving contact 15 rotates in the opposite direction to the left of the second stationary contact 13, forming an electrical connection between the moving contact 15 and the second stationary contact 13. In this embodiment, the moving contact 15 needs to rotate more than 180° to achieve the switching from the first stationary contact 12 to the second stationary contact 13. This large-angle rotation cannot be achieved using a tension spring; only a torsion spring 20 can achieve it.

[0054] Specifically, as shown in the attached document Figures 5-11 As shown, the cavity 111 is provided with a first driving surface 114 and a second driving surface 115. In a first state, a first gap 116 is provided between the first driving surface 114 and the moving contact 15. The rotating member 11 rotates through the first gap 116, causing the first driving surface 114 to abut against the moving contact 15, thereby achieving the effect of the rotating member 11 driving the moving contact 15 to rotate. In a second state, a second gap 117 is provided between the second driving surface 115 and the moving contact 15. The rotating member 11 rotates through the second gap 117, causing the second driving surface 115 to abut against the moving contact 15, thereby achieving the effect of the rotating member 11 driving the moving contact 15 to rotate. The arrangement of the first gap 116 and the second gap 117 forms a buffering effect.

[0055] Specifically, as shown in the attached document Figures 5-11 As shown, the moving contact 15 has a rotating part 154, which has a first through hole 155. The rotating component 11 has a second through hole 118, and the first through hole 155 and the second through hole 118 are coaxially arranged. At this time, the pin passes through the first through hole 155 and the second through hole 118, causing the moving contact 15 to rotate relative to the pin. The pin is connected to the rotating component 11; when the pin rotates, it drives the rotating component 11 to rotate, and the moving contact 15 rotates relative to the pin. The pin is not shown in the attached figure, but those skilled in the art should know how the pin is arranged. Alternatively, other connection methods can be used to achieve the relative rotation effect of the moving contact 15.

[0056] Specifically, as shown in the attached document Figures 5-11As shown, it also includes two arc-extinguishing components 17, which are respectively disposed on one side of the first stationary contact 12 and the second stationary contact 13. One arc-extinguishing component 17 is located on the path through which the first contact head 151 moves to engage with the first stationary contact 12, and the other arc-extinguishing component 17 is located on the path through which the second contact head 152 moves to engage with the second stationary contact 13. The arrangement of the arc-extinguishing components 17 creates an arc-extinguishing effect. Here, the arc-extinguishing component 17 includes an arc-extinguishing grid, which is prior art and will not be described in detail.

[0057] Specifically, as shown in the attached document Figures 5-11 As shown, the moving contact 15 is provided with a connecting portion 156, which is flexibly connected to the third stationary contact 14. The connecting portion 156 facilitates the electrical connection between the third stationary contact 14 and the moving contact 15. This flexible connection can be a soft copper wire connection or a conductor connection. One end of the soft copper wire is connected to the third stationary contact 14, and the other end is connected to the connecting portion 156.

[0058] Specifically, in the third state, the first stationary contact 12 separates from the first contact head 151, and the second stationary contact 13 separates from the second contact head 152, resulting in a complete disconnection.

[0059] Specifically, the switch in this embodiment can be a dual-power switch or a double-throw isolating switch.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
