Description

Technical Field

[0001] This invention relates to the field of switch technology, and more particularly to a stacked dual-circuit independent switch. Background Technology

[0002] Switches, as common electrical control components, are widely used in lighting, electrical control, and other applications. Depending on their function and structure, switches are classified into single-gang, double-gang, and multi-gang types, as well as single-control, double-control, and multi-control types. Among these, the double-gang single-pole switch (also known as a dual-path single-pole switch) is a common structural form. This type of switch typically has two operating areas on a panel: the upper part controls the first circuit, and the lower part controls the second circuit, thus enabling a single switch to independently control two loads simultaneously.

[0003] Figure 1 A schematic diagram of the wiring terminal arrangement for a dual-channel single-control switch provided for the prior art, as shown below. Figure 1 As shown, in the prior art, the typical wiring method for a double-pole single-control switch is as follows: two common terminals are set, each connected to the live wire of the power supply; simultaneously, a first output terminal (L1 pole) and a second output terminal (L2 pole) are set, each connected to the first load and the second load, respectively. In this way, the switch can achieve one input and one output, that is, the common terminal to L1 pole controls one path, and the common terminal to L2 pole controls the other path.

[0004] In existing technologies, L1 and L2 poles typically each have only one terminal, mainly due to limitations imposed by the switch body size and wiring method. For common small-sized switches, if a crimp-type wire disconnection structure is used, this structure requires a certain amount of space at each pole position, making it difficult to simultaneously arrange more wiring ports within a limited installation space. Consequently, each output terminal generally can only have one wiring hole, failing to directly meet the requirement of connecting multiple loads to one circuit.

[0005] However, with the increasing complexity of usage scenarios, existing switch structures have the following shortcomings:

[0006] First, the number of output terminals is limited. Traditional L1 and L2 output terminals each have only one wiring hole, which can only be directly connected to one load. If two or more loads need to be controlled simultaneously by the same switch, it must be achieved externally through terminals, parallel wiring, etc., which not only increases the complexity of construction but also easily leads to messy wiring and safety hazards.

[0007] Secondly, it has poor scalability. When users renovate or upgrade their homes, if they want to add lights or appliances controlled by the same circuit, they often need to rewire or install wiring terminals, which lacks flexibility.

[0008] Third, reliability and safety issues. In the existing structure, if the user leads out multiple wires through a single wiring hole, it is easy to cause the compression to be not firm, the contact to be poor, and further to cause heating or safety accidents.

[0009] In summary, the existing double single control switch has obvious limitations in the number and function of the output end, especially with the extrusion disconnection structure in the miniaturized product, limited by the space occupation of the extrusion disconnection structure, only a limited number of wiring terminals can be provided, and it is difficult to meet the use demand of controlling multiple loads.

[0010] Therefore, to solve the problem of space limitation of the double single control switch in the prior art, a compact switch structure and layout method are provided, which becomes a technical problem urgently to be solved in the field. SUMMARY

[0011] The purpose of the present application is to provide a stacked double-circuit independent switch to solve the above technical problems in the prior art.

[0012] The stacked double-circuit independent switch comprises a button, a dialing block, a transmission assembly, a pressing assembly, a bearing assembly, a first pole module, a second pole module and a common terminal module. The pressing assembly and the bearing assembly are relatively matched, and a first accommodating cavity, a second accommodating cavity and a third accommodating cavity located between the first accommodating cavity and the second accommodating cavity are defined therebetween. The first accommodating cavity is used for accommodating the first pole module, the second accommodating cavity is used for accommodating the second pole module, and the third accommodating cavity is used for accommodating the transmission assembly and the common terminal module. The button is fixedly connected with the dialing block, and the dialing block is fixedly connected with the transmission assembly. The transmission assembly is provided with a first contact portion, a second contact portion and a third contact portion, and the third contact portion is in contact with the common terminal module. When the button is operated, the dialing block drives the transmission assembly to be located at a first position or a second position in the third accommodating cavity. When the transmission assembly is located at the first position, the first contact portion is in contact with the first pole module. When the transmission assembly is located at the second position, the first contact portion is in contact with the second pole module.

[0013] Further, the pressing assembly includes a first pressing plate and a second pressing plate, and the bearing assembly includes a rear core. The first pressing plate and the rear core are respectively matched. The second pressing plate includes a surrounding wall and a through cavity formed by the surrounding wall. The through cavity has a first opening and a second opening opposite to each other. The surrounding wall has a first notch and a second notch opposite to each other. The actuating block extends into the second pressing plate from the first opening, and the third contact portion of the transmission assembly extends out from the second opening of the second pressing plate. When the transmission assembly is in the first position, the first pole module contacts the first contact portion through the first notch. When the transmission assembly is in the second position, the second pole module contacts the second contact portion through the second notch.

[0014] Further, the first pole module, the second pole module, and the common terminal module each sequentially include a first pole in contact with the first contact portion, a second pole in contact with the second contact portion, and a common terminal in contact with the transmission assembly; the first pole, the second pole, and the common terminal each have a wiring cavity, and a wiring spring is disposed within the wiring cavity. The wiring cavity has a back and a front portion opposite to the back, and the front portion has a through hole adapted to the disconnect button, the disconnect button being disposed corresponding to the through hole; the wiring spring includes a wiring template. The device includes a main body and at least two hook-shaped contact portions extending from it for contacting different wires. The main body contacts the back of the wire-holding cavity, and the hook-shaped contact portions form a wire-holding space between it and the front to accommodate the wires. When wiring, the hook-shaped contact portions contact and limit the wires when the wires are inserted into the wire-holding space. When disconnecting the wires, the disconnecting tool presses the disconnecting button to move it through the through hole toward the back, causing the hook-shaped contact portions to deform and creating a wire-out space to pull out the wires.

[0015] Furthermore, the top outer surface of the common terminal's wiring cavity is provided with an arc-shaped groove; the transmission assembly includes an elastic element and a swing plate fixedly connected to the elastic element, the first contact portion and the second contact portion are located on both sides of the swing plate, the third contact portion is located at the end of the swing plate, and the third contact portion is disposed in the arc-shaped groove; when the button is operated, the toggle block drives the elastic element to deform, causing the swing plate to swing around the arc-shaped groove as a fulcrum until the first contact portion of the swing plate contacts the first pole, or the second contact portion of the swing plate contacts the second pole.

[0016] Further, the wiring body is an H-shaped body, and the wiring spring includes four hook-shaped contact portions extending from the four ends of the H-shaped body, wherein two hook-shaped contact portions located on the same side of the H-shaped body are used to contact the same wire, and each wiring spring connects two wires; the first pole includes a first back and a first front portion disposed opposite to each other, two first side portions disposed opposite to each other, and a first contact end extending from the first back portion, wherein the first back portion, the first front portion, and the two first side portions form the wiring cavity, and the two side portions extend inward from the two sides of the through hole of the first front portion to divide the space on the front side of the wiring cavity, forming spaces on both sides of the through hole of the first front portion corresponding to the hook-shaped contact portions on both sides of the wiring spring; the H-shaped body contacts the first back portion, and the hook-shaped contact portions on both sides of the wiring spring are respectively located in the spaces on both sides of the through hole of the first front portion; the second pole has the same structure as the first pole, and the second pole includes a second contact end; the first contact end contacts the first contact portion, and the second contact end contacts the second contact portion.

[0017] Furthermore, the elastic element is a spring; the middle part of the actuating block protrudes outward to form a tubular cavity, the tubular cavity is a blind hole structure, used to accommodate the spring; the middle part of the first end of the swing plate has a flared notch with a gradually decreasing diameter, the bottom of the flared notch is provided with a limiting protrusion, the first end of the spring abuts against the bottom of the tubular cavity, and the second end of the spring is sleeved on the limiting protrusion.

[0018] Further, the first pressure plate includes a first enclosure wall located in the middle, and a first protrusion and a second protrusion located at both ends; the rear core includes a second enclosure wall located in the middle, and a first recess and a second recess located at both ends; wherein, the first pressure plate and the rear core are assembled opposite to each other, the first protrusion and the first recess form the first receiving cavity, the second protrusion and the second recess form the second receiving cavity, and the first enclosure wall and the second enclosure wall form the third receiving cavity.

[0019] Furthermore, the rear core is provided with a first disconnect hole and a first connection hole penetrating the first receiving cavity. The first disconnect hole corresponds to the disconnect button in the first pole module, and the first connection hole corresponds to the wiring space of the first pole. The rear core is also provided with a second disconnect hole and a second connection hole penetrating the second receiving cavity. The second disconnect hole corresponds to the disconnect button in the second pole module, and the second connection hole corresponds to the wiring space of the second pole. The rear core is also provided with a third disconnect hole and a third connection hole penetrating the third receiving cavity. The third disconnect hole corresponds to the disconnect button in the common terminal module, and the third connection hole corresponds to the wiring space of the common terminal.

[0020] Furthermore, one side of the button is the operating surface, and the other side of the button is provided with a receiving cavity. Two first snap-fit ​​structures are respectively provided on the two opposite side walls of the receiving cavity. The toggle block is an integral structure, and a second snap-fit ​​structure is provided at each of the four corners. The first snap-fit ​​structure and the second snap-fit ​​structure are engaged in a locking fit.

[0021] Furthermore, the actuating block also includes two polygonal extensions and two recesses arranged opposite to each other; a third snap-fit ​​structure is provided in the recesses, and the third snap-fit ​​structure snaps into the holding component.

[0022] The present invention provides a stacked dual-circuit independent switch, comprising: a button, a toggle block, a transmission assembly, a holding assembly, a carrying assembly, a first pole module, a second pole module, and a common terminal module. The holding assembly and the carrying assembly cooperate with each other, defining a first receiving cavity for accommodating the first pole module, a second receiving cavity for accommodating the second pole module, and a third receiving cavity located between the first and second receiving cavities, accommodating the transmission assembly and the common terminal module. The button is fixedly connected to the toggle block, and the toggle block is fixedly connected to the transmission assembly. When the button is operated, the toggle block drives the transmission assembly to a first position or a second position within the third receiving cavity. When the transmission assembly is in the first position, its first contact portion contacts the first pole module; when the transmission assembly is in the second position, its first contact portion contacts the second pole module, and its third contact portion contacts the common terminal module. This invention, through the relative cooperation of the holding component and the bearing component, defines three cavities for installing the first pole module, the second pole module, and the transmission component and common terminal module, respectively. This cavity partitioning arrangement allows for a rational spatial division of the functional modules, avoiding mutual interference and achieving a compact internal structure for the switch, facilitating miniaturization design. Simultaneously, in the third receiving cavity, the transmission component is in continuous contact with the common terminal module. A button drives a toggle block, which in turn drives the transmission component. The transmission component and toggle block cooperate, allowing the transmission component to contact the first or second pole module at different positions, ensuring clear action transmission and reliable switching of different circuits. Since the first pole module, second pole module, and common terminal module are all installed within the receiving cavities, one or more wiring holes can be provided on each module. Users can connect the same wiring terminal to one or more loads according to actual needs. Compared to the existing technology where each L1 and L2 pole has only one wiring hole, this allows for functional expansion to support multiple loads per circuit, reducing external parallel wiring operations and improving construction convenience. In summary, due to the structural design of this embodiment, modular partitioning is achieved within a limited switch volume, allowing the first pole module, second pole module, and common terminal module to be configured with one or more wiring holes as needed, thereby resulting in a compact switch structure, flexible connection, simple construction, and safe and reliable technical effects.

[0065] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0066] refer to Figures 2 to 33 As shown, the embodiments of this application will be described in detail below.

[0067] In one embodiment, such as Figures 2 to 6 As shown, the stacked dual-circuit independent switch in this embodiment includes: a button 10, a toggle block 20, a transmission component 30, a holding component 40, a bearing component 50, a first pole module 60, a second pole module 70, and a common terminal module 80.

[0068] Among them, such as Figure 7 As shown, button 10 is an externally exposed component of the stacked dual-circuit independent switch, directly operated by the user. Its function is to switch the circuit on and off by driving the internal contact group through a mechanical transmission mechanism. It is typically a rectangular or square button, covering the front of the switch. In the stacked dual-circuit independent switch, button 10 is divided into a first half and a second half, each controlling two different circuits. The first half and the second half are distinguished by a dividing line or a raised design to prevent accidental operation. When the user presses the first half, one internal contact closes; when the user presses the second half, the other internal contact closes.

[0069] like Figure 2 , Figure 3 and Figure 5As shown, button 10 is fixedly connected to toggle block 20, and toggle block 20 is fixedly connected to transmission assembly 30. When button 10 is operated, toggle block 20 is driven, further driving transmission assembly 30 to different positions. Holding assembly 40 and bearing assembly 50 cooperate with each other, defining a first receiving cavity, a second receiving cavity, and a third receiving cavity located between the first and second receiving cavities. The first receiving cavity is used to accommodate the first pole module 60, the second receiving cavity is used to accommodate the second pole module 70, and the third receiving cavity is used to accommodate the transmission assembly 30 and common terminal module 80. The first pole module 60, the second pole module 70, and the common terminal module 80 are metal modules that realize the switching of the circuit.

[0070] The transmission assembly 30 is provided with a first contact portion 321, a second contact portion 322 and a third contact portion 323. The third contact portion 323 is in continuous contact with the common terminal module 80. The first contact portion 321 is used to contact the first pole module 60, and the second contact portion 322 is used to contact the second pole module 70. The first pole module 60 is provided with one or more wiring holes to connect to one or more loads located in the first circuit. The second pole module 70 is also provided with one or more wiring holes to connect to one or more loads located in the second circuit. The common terminal module 80 is provided with one or more wiring holes.

[0071] When button 10 is activated, the toggle block 20 drives the transmission assembly 30 to be positioned in either the first or second position within the third receiving cavity, such as... Figure 3 and Figure 4 As shown, when the transmission assembly 30 is in the first position, the first contact portion 321 contacts the first pole module 60, connecting the various loads of the first circuit; as Figure 5 and Figure 6 As shown, when the transmission assembly 30 is in the second position, the first contact portion 321 contacts the second pole module 70, connecting each load of the second circuit.

[0072] The stacked dual-circuit independent switch provided in this embodiment, through the relative cooperation of the holding component and the bearing component, defines three cavities for installing the first pole module, the second pole module, and the transmission component and common terminal module, respectively. This cavity partitioning arrangement allows for a reasonable spatial division of the functional modules, avoiding mutual interference, thereby achieving a compact internal structure of the switch and facilitating miniaturization design. Simultaneously, in the third receiving cavity, the transmission component is in continuous contact with the common terminal module; a button drives a toggle block, which in turn drives the transmission component. The transmission component and the toggle block cooperate to ensure that the transmission component contacts the first pole module or the second pole module at different positions, achieving clear action transmission and ensuring the reliability of different circuit connections. Since the first pole module, the second pole module, and the common terminal module are all installed within the receiving cavities, one or more wiring holes can be provided on each module. Users can connect the same wiring terminal to one or more loads according to actual needs. Compared to the existing structure where each L1 pole and L2 pole has only one wiring hole, this allows for functional expansion of one circuit corresponding to multiple loads, reducing external paralleling operations and improving construction convenience. In summary, due to the structural design of this embodiment, modular partitioning is achieved within a limited switch volume, allowing the first pole module, second pole module, and common terminal module to be configured with one or more wiring holes as needed, thereby resulting in a compact switch structure, flexible connection, simple construction, and safe and reliable technical effects.

[0073] Alternatively, in one embodiment, such as 8 to Figure 14As shown, the actuating block 20 is engaged with the holding assembly 40, which cooperates with the supporting assembly 50. The holding assembly 40 includes a first pressure plate 41 and a second pressure plate 42. The supporting assembly 50 includes a rear core 51. The first pressure plate 41 and the rear core 51 cooperate with each other. A portion of the second pressure plate 42 is located within the first pressure plate 41, and another portion is located within the rear core 51. The second pressure plate 42 includes a surrounding wall 421 and a through cavity formed by the surrounding wall 421. The through cavity constitutes part of a third receiving cavity, and another portion of the third receiving cavity is located within the rear core 51. The through cavity has a first opening and a second opening opposite to each other. The surrounding wall has a first notch 422 and a second notch 423 opposite to each other. The first notch 422 communicates with the first receiving cavity, and the second notch 423 communicates with the second receiving cavity. The actuating block 20 extends into the second pressure plate 42 through the first opening, and the third contact portion 323 of the transmission assembly 30 connected to the actuating block 20 extends out from the second opening of the second pressure plate 42 and contacts the common end module 80. When the transmission assembly 30 is in the first position, the first pole module 60 located in the first receiving cavity contacts the first contact portion 321 of the transmission assembly 30 located in the third receiving cavity through the first notch 422. When the transmission assembly 30 is in the second position, the second pole module 70 located in the second receiving cavity contacts the second contact portion 322 of the transmission assembly 30 located in the third receiving cavity through the second notch 423.

[0074] The stacked dual-circuit independent switch provided in this embodiment employs a structure in the holding assembly where a first pressure plate and a second pressure plate work together to enclose a cavity. This rationally divides the internal space, forming independent first, second, and third receiving cavities. Through the through-cavity and notch design on the second pressure plate, the actuating block, transmission assembly, and various hardware modules can be arranged and interconnected within their respective cavities. This structure not only makes the switch more compact, facilitating assembly and miniaturization, but also ensures a clear transmission path and accurate contact position, thereby improving conductivity reliability and service life.

[0075] Alternatively, in one embodiment, as shown in the figures above and Figures 15 to 20 As shown, the first pole module 60 includes a first pole 61 that contacts the first contact portion 321, the second pole module 70 includes a second pole 71 that contacts the second contact portion 322, and the common terminal module 80 includes a common terminal 81 that contacts the transmission assembly 30. Furthermore, the first pole 61, the second pole 71, and the common terminal 81 each have a wiring cavity, and the wiring cavity contains a wire spring and a disconnect button with the same structure. It should be noted that, for ease of description and distinction, the wire springs, disconnect buttons, etc., in the first pole module 60, the second pole module 70, and the common terminal module 80 are assigned different numbers, which do not constitute a structural difference limitation.

[0076] Among them, such as Figure 15and Figure 16 As shown, the first pole 61 has a first wiring spring 62, the wiring cavity has a first back 611 and a first front part 612 disposed opposite to the first back 611, the first front part 612 has a first through hole 613 adapted to the first disconnect button 63, and the first disconnect button 63 is disposed corresponding to the first through hole 613.

[0077] The first connector spring 62 includes a first connector body 621 and at least two first hook-shaped contact portions 622 extending from the first connector body 621 for contacting different wires. The first connector body 621 contacts the first back side 611 of the wire placement cavity, and a wire placement space for accommodating wires is formed between the first hook-shaped contact portions 622 and the first front portion 612.

[0078] like Figure 17 and Figure 18 As shown, the second pole 71 has a second wiring spring 72, the wiring cavity has a second back 711 and a second front part 712 disposed opposite to the second back 711, the second front part 712 has a second through hole 713 adapted to the second disconnect button 73, and the second disconnect button 73 is disposed corresponding to the second through hole 713.

[0079] The second wiring spring 72 includes a second wiring body 721 and at least two second hook-shaped contact portions 722 extending from the second wiring body 721 for contacting different wires. The second wiring body 721 contacts the second back side 711 of the wire placement cavity, and a wire placement space for accommodating wires is formed between the second hook-shaped contact portions 722 and the second front portion 712.

[0080] like Figure 19 and Figure 20 As shown, the common terminal 81 has a third wiring spring 82, and the wiring cavity has a common terminal back 811 and a common terminal front 812 disposed opposite to the common terminal back 811. The common terminal front 812 has a third through hole 813 adapted to the third disconnect button 83, and the third disconnect button 83 is disposed corresponding to the third through hole 813.

[0081] The third connector spring 82 includes a third connector body 821 and at least two third hook-shaped contact portions 822 extending from the third connector body 821 for contacting different wires. The third connector body 821 contacts the back of the common end 811 of the wire placement cavity, and a wire placement space for accommodating wires is formed between the third hook-shaped contact portions 822 and the front of the common end 812.

[0082] like Figures 21 to 24 As shown, taking the connection or disconnection of wire 91 to the second pole module 70 as an example (connection or disconnection to the first pole module 60 is similar and will not be described again here):

[0083] When wiring, when the wire 91 is inserted into the wiring space, the second hook-shaped contact part 722 contacts and limits the wire 91. When disconnecting the wire, the disconnecting tool 92 squeezes the second disconnecting button 73, so that the second disconnecting button 73 moves through the second through hole 713 toward the second back 711, squeezing the second hook-shaped contact part 722 to deform, creating a wire outlet space to pull out the wire 91.

[0084] The stacked dual-circuit independent switch provided in this embodiment, by incorporating a wire-placement cavity, a wiring spring, and a through-hole structure that mates with the disconnect button in the first pole module, the second pole module, and the common terminal module, allows the wire to be reliably limited and stably conductive by the hook-shaped contact portion when inserted. Simultaneously, when disconnection is required, simply applying a disconnect tool to the disconnect button deforms the hook-shaped contact portion, creating a wire outlet space for easy wire removal. This structure not only simplifies wiring and disconnection operations and improves construction convenience but also ensures the reliability and safety of electrical connections. Furthermore, by providing at least two hook-shaped contacts for contacting different wires, it can support multiple wires being connected to a single terminal simultaneously, thereby enhancing the switch's scalability and applicability. Based on the stacked dual-circuit independent switch provided in this embodiment, each module can be equipped with two wiring holes and one disconnect hole on a dual-channel single-control switch with dimensions of approximately 46*24mm.

[0085] Alternatively, in one embodiment, as shown in the figures above and Figure 25 and Figure 26 As shown, the top outer surface of the wire-laying cavity of the common end 81 is provided with an arc-shaped groove 814. The transmission assembly 30 includes an elastic element 31 and a swing plate 32 fixedly connected to the elastic element 31. The first contact portion 321 and the second contact portion 322 are located on both sides of the swing plate 32, and the third contact portion 323 is located at the end of the swing plate 32, and the third contact portion 323 is disposed in the arc-shaped groove 814 to limit the swing of the swing plate 32. When the button 10 is operated, the elastic element 31 is deformed by the toggle block 20, such as... Figures 3 to 6 As shown, the pendulum 32 is made to swing around the arc-shaped groove 814 as the fulcrum until the first contact portion 321 of the pendulum 32 contacts the first pole 61, or the second contact portion 322 of the pendulum 32 contacts the second pole 71.

[0086] The stacked dual-circuit independent switch provided in this embodiment utilizes an arc-shaped groove on the outer surface of the common terminal's wiring cavity. The end of the swing plate in the transmission assembly is housed within this arc-shaped groove, allowing the swing plate to swing stably with the groove as a fulcrum. When the button is activated, the toggle block deforms the elastic element, reliably deflecting the swing plate at the fulcrum, connecting the first and second contact portions on either side to the first or second pole, respectively. This design not only ensures the stability of the swing plate's swing and the accuracy of the conduction position, improving the reliability and lifespan of the switch, but also provides a clear transmission path and a compact structure, making it suitable for miniaturized switch applications. Furthermore, the arc-shaped groove at the common terminal contacts the arc-shaped bottom of the swing plate, resulting in a larger contact area, better conductivity, and lower temperature rise compared to point contact methods in existing technologies.

[0087] Optionally, in one embodiment, the wiring springs in each module have the same structure. Taking the wiring spring in the second pole module as an example, such as... Figure 18 As shown, its second wiring head 721 is an H-shaped head, and the second wiring spring 72 includes four second hook-shaped contact parts 722 extending from the four ends of the H-shaped head. Among them, two second hook-shaped contact parts 722 located on the same side of the H-shaped head are used to contact the same wire, and the second wiring spring 72 connects two wires.

[0088] The first and second electrodes have the same structure. Taking the first electrode as an example, as follows... Figure 15 and 16 As shown, the first pole 61 includes a first back 611 and a first front 612 disposed opposite to each other, two first side portions 614 disposed opposite to each other, and a first contact end 615 extending from the first back 611. The first back 611, the first front 612, and the two first side portions 614 form a wiring cavity. The two side edges of the first through hole 613 of the first front portion 612 extend inwardly, dividing the space on the front side of the wiring cavity. First spaces 616 are formed on both sides of the first through hole 613, corresponding to the first hook-shaped contact portions 622 on both sides of the first connecting spring 62. The H-shaped main body contacts the first back 611, and the first hook-shaped contact portions 622 on both sides of the first connecting spring 62 are respectively located within the first spaces 616 on both sides of the first through hole 613. Figure 4 As shown, when the transmission assembly is in the first position, the first contact end 615 of the first pole 61 contacts the first contact portion 321 of the swing plate 32, as... Figure 6 As shown, the second pole 71 and the first pole 61 have the same structure. When the transmission assembly is in the second position, the second contact end 715 of the second pole 71 contacts the second contact portion 322 of the swing plate 32.

[0089] The stacked dual-circuit independent switch provided in this embodiment features an H-shaped main body with four hook-shaped contacts extending from its four ends. This allows two hook-shaped contacts on the same side to simultaneously clamp the same wire, enabling each contact spring to connect two wires. This structure increases wiring capacity compared to existing technologies, meeting the requirement of connecting two loads from one terminal. Simultaneously, it creates multi-point contact during wire insertion, improving conductivity stability and pull-out resistance. The space formed on both sides of the through-holes at the front of the first and second poles, combined with the hook-shaped contacts contacting different wires, accurately limits the wire's movement, further preventing loosening or misalignment and ensuring wiring reliability and safety.

[0090] Alternatively, in one embodiment, such as Figure 25 and Figure 26 As shown, the elastic element 31 is a spring, such as Figure 27 As shown, the middle part of the actuating block 20 protrudes outward to form a tubular cavity 21, which is a blind hole structure used to accommodate the spring. The middle part of the first end of the swing plate 32 has a flared notch 324 with a gradually decreasing diameter. The bottom of the flared notch 324 is provided with a limiting protrusion 325. The first end of the spring abuts against the bottom of the tubular cavity 21, and the second end of the spring is sleeved on the limiting protrusion 325.

[0091] The first half of the switch button 10 is located on the first side, and the second half is located on the second side. When the user presses the first half of the switch button 10, the button 10 causes the toggle block 20 to tilt towards the first side that is pressed. The tubular cavity of the toggle block 20 causes the spring to deform towards the second side, thereby causing the third contact portion 323 of the swing plate 32 to swing towards the second side with the arc-shaped groove 814 as the fulcrum in the common end 81, until the second contact portion 322 of the swing plate 32 contacts the second contact end 715 of the second pole 71, so that the circuit on the second side is connected. When the user presses the second half of the switch button 10, the button 10 causes the toggle block 20 to tilt towards the second side that is pressed. The tubular cavity of the toggle block 20 causes the spring to deform towards the first side, thereby causing the third contact portion 323 of the swing plate 32 to swing towards the first side with the arc-shaped groove 814 as the fulcrum in the common end 81, until the first contact portion 321 of the swing plate 32 contacts the first contact end 615 of the first pole 61, so that the circuit on the first side is connected.

[0092] The stacked dual-circuit independent switch provided in this embodiment uses a blind-hole tubular cavity integrally formed in the middle of the toggle block to axially limit one end of the spring, and the other end of the spring is sleeved on the limiting protrusion at the bottom of the trumpet-shaped notch at the first end of the swing plate. This makes the direction of the spring force coaxial with the transmission path, which not only prevents the spring from lateral swinging and deflection during compression and reset, but also provides stable preload and guidance, and simplifies assembly and positioning. This can significantly improve the smoothness of the operation and repeatability of the transmission components, reduce jamming and wear, extend the service life of the whole machine, and facilitate miniaturization.

[0093] Alternatively, in one embodiment, such as Figure 10 As shown, the first pressure plate 41 includes a first enclosure wall 411 located in the middle, and a first protrusion 412 and a second protrusion 413 located at both ends. The rear core 51 includes a second enclosure wall 511 located in the middle, and a first recess 518 and a second recess 519 located at both ends. The first pressure plate 41 and the rear core 51 are assembled opposite to each other, the first protrusion 412 and the first recess 518 form a first receiving cavity, the second protrusion 413 and the second recess 519 form a second receiving cavity, and the first enclosure wall 411 and the second enclosure wall 511 form a third receiving cavity.

[0094] The stacked dual-circuit independent switch provided in this embodiment uses the first pressure plate's enclosure wall and the protrusion to cooperate, and the core's enclosure wall and the recessed partition to enclose the first, second and third receiving cavities located therebetween. This achieves spatial decoupling and rigid limiting of the conductive electrode module, transmission module and common terminal module, ensuring that the mounting surfaces of each functional component are consistent and the positioning is reliable, reducing mutual interference, and also improving the overall structural strength and deformation resistance of the housing. Thus, modularization, compactness and high assembly consistency are achieved within a limited volume, improving electrical safety margin and reliability.

[0095] Alternatively, in one embodiment, such as Figure 10 , Figure 28 and Figure 29 As shown, the rear core 51 is provided with a first disconnect hole 512 and a first wiring hole 513 penetrating the first receiving cavity. The first disconnect hole 512 corresponds to the first disconnect button 63 in the first pole module 60, and the first wiring hole 513 corresponds to the wiring space of the first pole 61. The rear core 51 is also provided with a second disconnect hole 514 and a second wiring hole 515 penetrating the second receiving cavity. The second disconnect hole 514 corresponds to the second disconnect button 73 in the second pole module 70, and the second wiring hole 515 corresponds to the wiring space of the second pole 71. The rear core 51 is also provided with a third disconnect hole 516 and a third wiring hole 517 penetrating the third receiving cavity. The third disconnect hole 516 corresponds to the third disconnect button 83 in the common terminal module 80, and the third wiring hole 517 corresponds to the wiring space of the common terminal 81.

[0096] The stacked dual-circuit independent switch provided in this embodiment has corresponding wiring holes and wire removal holes on the first, second and third receiving cavities on the rear core, so that the wiring space of the wiring spring and the wire removal button have direct access channels. That is, when wiring, the wire insertion path is short, the contact is reliable and not easy to deviate; when removing the wire, the wire can be released by simply pressing the wire removal button along the hole, which is intuitive and avoids accidental contact with other components. This significantly improves the wiring / removal efficiency and reduces the assembly difficulty.

[0097] Alternatively, in one embodiment, such as Figure 30 As shown, one side of the button 10 is the operating surface, and the other side extends from the back of the operating surface to form a receiving cavity 11. Two first locking structures 12 are respectively provided on the two opposite side walls of the receiving cavity 11. The toggle block 20 is an integral structure, which includes opposite first and second sides, as well as opposite third and fourth sides. The four corners of the first and second sides extend outward to form protrusions. At the protrusions of the third and fourth sides, second locking structures 22 are respectively provided. The toggle block 20 is engaged with the first locking structures 12 of the button 10 through the four second locking structures 22.

[0098] The stacked dual-circuit independent switch provided in this embodiment has a receiving cavity formed on the back of the button, which limits and accommodates the toggle block. The first snap-fit ​​structure on both sides of the receiving cavity and the second snap-fit ​​structure of the toggle block are provided for multi-point engagement, which can achieve self-positioning and uniform locking at the moment of assembly, and reduce the shaking and cumulative gap between the operating surface and the toggle block.

[0099] Alternatively, in one embodiment, such as Figures 30 to 33 As shown, the actuating block 20 also includes two oppositely arranged polygonal extensions 23 and two recesses 24; a third engaging structure 25 is provided in the recess 24, and the third engaging structure 25 engages with the holding assembly 40. Specifically, on the third and fourth sides, a polygonal extension 23 extending outward is provided between the two second engaging structures 22 on each side. The polygonal extension 23 is used to guide and limit the engagement of the actuating block 20 with the button 10, so as to ensure the stability of the assembly of the actuating block 20 and the button 10. At the same time, each polygonal extension 23 forms a support between the two second engaging structures 22 to enhance the strength of the actuating block 20 in the lateral direction and avoid damage caused by stress concentration. On the first and second sides, a recess 24 is defined between the two protrusions on each side. A third engaging structure 25 is provided at the position of the recess 24, and the actuating block 20 engages with the fourth engaging structure 414 of the first pressure plate 41 through the third engaging structure 25.

[0100] The stacked dual-circuit independent switch provided in this embodiment has a relatively polygonal extension on the toggle block that provides a geometric reference for anti-rotation and guidance. The third snap-fit ​​structure in the recessed part and the pressing component form an auxiliary locking and limiting mechanism, so that the toggle block can be stably supported in multiple axial directions, which can avoid the sway caused by lateral force during transmission.
