Description

Technical Field

[0001] This invention relates to the field of electrical switch technology, and more particularly to a multi-control wall switch. Background Technology

[0002] Multi-control wall switches, as core components of distributed circuit control, are widely used in various low-voltage circuit control scenarios such as home lighting, commercial shops, and offices. They undertake the core functions of independent start-up and shutdown of multiple circuits and zoned control. Most conventional products on the market adopt modular splicing or multi-unit integrated structure, which controls different branch circuits through multiple independent switch units to meet the centralized control needs of multiple areas and multiple lines, and have become a common accessory in daily electrical wiring.

[0003] When the circuit containing the switch experiences current overload, partial short circuit, or abnormal heating due to poor contact of the internal contacts, the continuous accumulation of internal heat prevents timely power cut-off. This not only accelerates the aging and deformation of internal components such as the plastic housing and terminals, but also poses safety hazards such as short circuits, housing burning, and even leakage and fire, threatening electrical safety. Furthermore, the multiple control units, terminals, and fixing clips within this type of switch are interconnected, resulting in a high degree of integration but also overly strong structural interrelationships. During later maintenance, disassembly, line repair, or component replacement, faulty components are prone to loosening, wiring detachment, or even internal misalignment. This not only disrupts the internal structure but also increases the difficulty of repair and the probability of rework, significantly raising the operational threshold for installation and maintenance.

[0004] In addition, existing switches often lack intuitive indicators when malfunctioning, making it difficult for users to quickly identify the fault location. Users and maintenance personnel cannot quickly locate the faulty branch and cause of the fault, and can only troubleshoot one by one, which is time-consuming and laborious. Furthermore, if the temperature recovers after the circuit is disconnected, the switch may frequently turn on and off, causing unstable operation of controlled lights and electrical appliances, affecting the lifespan of equipment and the stability of the circuit.

[0005] Therefore, there is a need for a multi-control wall switch that can solve the above-mentioned defects, and can also protect against overheating and avoid frequent tripping. Summary of the Invention

[0010] Preferably, a traction groove is provided on one side of the rocker; a positioning pin is fixedly connected to the side wall of the pressure rod, the positioning pin can slide along the traction groove, and the rotation of the pressure rod can disengage the positioning pin from the traction groove; a guide groove is provided inside the mounting cover, one end of the rocker is placed in the guide groove, and the rocker can slide along the guide groove.

[0011] Preferably, the mounting cover has an arc-shaped groove in the middle, the guide sleeve is placed in the arc-shaped groove and can slide along it; the housing has a locking groove at the position corresponding to the mounting cover; the mounting cover is fixedly connected to an elastic limiting member at the position corresponding to the locking groove, and the elastic limiting member can be engaged in the corresponding locking groove.

[0012] Preferably, the synchronization plate has clearance holes at both ends, and the pressure rods pass through the corresponding clearance holes; a guide rod is fixedly connected to one side of the synchronization plate, the end of the guide rod penetrates the housing, and a reset member is sleeved on the outside of each guide rod.

[0013] Preferably, a gripping disc is fixedly connected to the outer side of the pressing sleeve for adjusting the relative rotation of the pressing sleeve and the guide sleeve; a synchronizing sleeve is fixedly connected to the side of the panel near the housing, and the synchronizing sleeves are respectively sleeved on the ends of the corresponding pressing sleeves.

[0014] Preferably, a limiting boss is fixedly connected to the inner side of the outer frame, and a limiting notch is provided on the panel corresponding to the position of the limiting boss. The limiting notch is engaged with the outer side of the limiting boss. A fluorescent part is fixedly installed on the side of the panel away from the housing to facilitate observation of the panel position.

[0015] Preferably, limiting grooves are provided in the housing at the positions corresponding to the input plate, the first output plate, and the second output plate to prevent them from shaking; the ends of the mounting covers are in contact with the end faces of the corresponding input plate, the first output plate, and the second output plate.

[0016] Preferably, the connecting terminals are interference-fitted to the side of the housing away from the end face, and each connecting terminal is fitted with a bolt for pressing the wire to the corresponding input board, the first output board and the second output board.

[0017] This invention provides a multi-control wall switch, which has at least the following beneficial effects: 1. This invention, by incorporating a pressure sleeve, pressure rod, moving magnet, guide rod, stationary magnet, and elastic element, effectively achieves the purpose of overheating circuit disconnection. During use, the heat from the rocker is conducted to the moving magnet through the pressure rod, causing its magnetic force to decrease, thus weakening the repulsive force between it and the stationary magnet. Under the action of the elastic element, the moving magnet drives the pressure rod to move towards the stationary magnet, while the positioning pin drives the rocker upward synchronously through the traction groove, causing the rocker to disengage from the input board, disconnecting the circuit, achieving automatic power-off protection, and improving electrical safety.

[0018] 2. This invention, by incorporating a retaining ring, an elastic spring, a limiting ring, and a reset notch, avoids the problem of frequent switching on and off caused by temperature recovery after circuit disconnection. When the magnetic force of the moving magnet decreases, it slides towards the side closer to the stationary magnet. The guide rod drives the retaining ring, causing the end of the elastic spring to enter the limiting ring but not correspond to the reset notch. The positions of the guide rod and the moving magnet are temporarily locked, preventing them from automatically resetting even after the temperature drops and the magnetic force of the moving magnet recovers after circuit disconnection. When it is necessary to reset the moving magnet and the pressure rod, the limiting ring is rotated to align the reset notch with the elastic spring. The repulsive force between the moving and stationary magnets causes the end of the elastic spring to slide out of the limiting ring. Then, the limiting ring is manually rotated at a certain angle to misalign the reset notch with the elastic spring, completing the reset. The wall switch can then be reassembled and used again.

[0019] 3. This invention achieves the purpose of indicating faults by setting up a guide rod, elastic spring, limiting ring, color plate, and indicator. Under normal conditions, there is a gap between the end of the color plate and the surface of the panel, and it is in a slightly retracted state, which is not easily noticed from the outside. When the temperature rises and the moving magnet approaches the stationary magnet, the circuit component is disconnected, and the guide rod pushes the elastic spring into the limiting ring to lock the guide rod. At the same time, the end of the color plate approaches the indicator on the surface of the panel. Users can intuitively identify the faulty circuit through the color change of the indicator, reducing fault diagnosis time and improving repair efficiency.

[0020] 4. This invention, by incorporating a synchronization plate, clearance holes, guide rods, and a reset component, effectively avoids the problem of internal structural chaos during switch assembly and disassembly. When one side of the contact assembly / circuit assembly malfunctions, the lowering sleeve on the non-faulty side is manually rotated, causing the bottom of the lowering sleeve to press against the synchronization plate. At this time, both rocker arms on both sides are pressed against the corresponding input boards, with the rocker arms in the middle position. Neither end of the rocker arms contacts the corresponding first or second output board, thus disconnecting the circuit. Subsequently, the guide rod on the faulty side is manually rotated, causing the positioning pin to slide out of the corresponding traction groove, allowing the contact assembly on the faulty side to be removed, thus preventing the circuit assembly structure from becoming chaotic.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides, for example Figures 1 to 7The multi-control wall switch shown includes an outer frame 1 and a panel 2 movably mounted on one side of the outer frame 1. The switch is typically activated by swinging. A housing 3 is fixedly mounted on the side of the outer frame 1 away from the panel 2 to house and protect the internal electrical components. The outer frame 1, panel 2, and housing 3 are preferably made of high-temperature resistant and flame-retardant material. The switch also includes: two circuit assemblies 4, each mounted inside the housing 3 and connected to a circuit. The two circuit assemblies 4 are mounted on the left and right sides of the inner side of the housing 3, respectively, for independently controlling the on / off state of two circuits. The two circuit assemblies 4 are arranged in a circumferential array along the centerline of the housing 3; and a contact assembly 5. Each of the circuit components 4 corresponds to a circuit component 4 and is used to control the state of the circuit component 4, transmitting the swing operation of the panel 2 to the corresponding circuit component 4; the indicator part 6 is located in the middle of the panel 2 and corresponds to the corresponding contact component 5, and is used to indicate the circuit state. The side of the panel 2 away from the housing 3 of the indicator part 6 adopts a transparent / semi-transparent film structure to ensure the flatness and sealing of the panel 2; a synchronization plate 7 is slidably installed inside the housing 3, with its two ends respectively placed at the ends of the corresponding pressing sleeve 503, for pressing the circuit component 4 when disassembling the contact component 5, and for fixing the internal structure during disassembly and maintenance to prevent the components from falling off.

[0031] Specifically, the contact assembly 5 includes a mounting cover 501, which is detachably mounted on the side of the housing 3 near the panel 2 by means of clips or screws, and a guide sleeve 502 is slidably mounted in the middle of the cover. The guide sleeve 502 can swing relative to the housing 3 and can be removed from the housing 3. A pressing sleeve 503 is threaded in the middle of the cover and is movably inserted into the side of the panel 2 near the housing 3. The pressing sleeve 503 can swing with the panel 2 and make the guide sleeve 502 swing synchronously. A pressure rod 504 is slidably mounted in the pressing sleeve 503, and one end contacts the rocker arm 402 of the circuit assembly 4. The other end is fixedly connected to a moving magnet 505. In order to better contact the rocker arm 402, the side of the pressure rod 504 corresponding to the rocker arm 402 is flat, increasing the contact with the rocker arm 402. Contact area; guide rod 506, which is fixedly connected to the side of the moving magnet 505 away from the pressure rod 504, the end of the guide rod 506 corresponds to the indicator part 6, and the guide rod 506 is placed inside the pressure sleeve 503; stationary magnet 507, which is fixedly installed inside the pressure sleeve 503, the guide rod 506 slides through the middle of the stationary magnet 507, and an elastic element 508 is fixedly connected between the stationary magnet 507 and the moving magnet 505; the moving magnet 505 and the stationary magnet 507 are magnetically repelled; both the moving magnet 505 and the stationary magnet 507 are permanent magnets, and magnetic repulsion is ensured during installation. Affected by the repulsive force, the moving magnet 505 will push the pressure rod 504 so that its end contacts the rocker plate 402. The elastic element 508 is a component with tension such as a tension spring, and the tension of the elastic element 508 is less than the repulsive force between the moving magnet 505 and the stationary magnet 507.

[0032] It should be noted that the pressure rod 504 is made of a material with high thermal conductivity, which can better conduct heat. The moving magnet 505 and the stationary magnet 507 are permanent magnets, such as neodymium iron boron magnets. Under normal conditions, the moving magnet 505 is located away from the stationary magnet 507. When the temperature of the circuit component 4 rises due to factors such as current overload, heat is conducted to the moving magnet 505 through the pressure rod 504. The magnetic force of the moving magnet 505 decreases after heating, resulting in a weakening of the repulsive force between it and the stationary magnet 507. Under the action of the elastic element 508, the moving magnet 505 will drive the pressure rod 504 to move towards the stationary magnet 507 (i.e., upwards), thereby triggering the circuit component 4 to disconnect the circuit, achieving automatic power-off protection in response to temperature changes, and improving safety.

[0033] More specifically, circuit assembly 4 includes: an input board 401, which is fixedly installed inside the housing 3, with one end corresponding to the pressure rod 504; a rocker 402, which is placed between the pressure rod 504 and the input board 401 and can swing relative to the input board 401, with the end of the input board 401 corresponding to the rocker 402 being arc-shaped to reduce friction between the rocker 402 and the input board 401; a first output board 403, which is fixedly installed inside the housing 3, with one end able to contact the end of the rocker 402; a second output board 404, which is fixedly installed inside the housing 3, with one end able to contact the end of the rocker 402, and the first output board 403 and the second output board 404 are fixedly connected to the ends of the rocker 402 with contacts to improve the stability of the circuit after connection; and connection terminals 405 are installed on the ends of the input board 401, the first output board 403 and the second output board 404 away from the rocker 402 for connecting lines.

[0034] In normal operation, when the user presses panel 2, the rocker arm 402 is driven to swing via the contact assembly 5. Its middle section is connected to the input board 401, and one end of the rocker arm 402 contacts the first output board 403 (or the second output board 404), thus connecting the circuit. When overheating occurs, the pressure rod 504 is driven upwards by the passive magnet 505, and the rocker arm 402 moves upwards synchronously under the influence of the pressure rod 504, causing its middle section to separate from the input board 401, thus disconnecting the circuit.

[0035] In this embodiment, the contact assembly 5 further includes a mechanism for fault indication and frequency skipping prevention. Specifically, the contact assembly 5 further includes: a retaining ring 509, which is fixedly fitted on the outside of the guide rod 506. At least two elastic springs 510 are fixedly connected to the outside of the retaining ring 509. The elastic springs 510 are evenly distributed around the circumference of the retaining ring 509 axis. The elastic springs 510 are preferably made of thin metal sheets and have an outward expansion elastic tendency. The elastic springs 510 are combined to form a downward-opening cone shape; and a limiting ring 511, which is rotatably mounted on... The pressure sleeve 503 is located away from the circuit assembly 4. The limiting ring 511 is sleeved on the outside of the guide rod 506 between the elastic spring 510 and the panel 2. The inner side of the limiting ring 511 has a reset notch 512, and the number of reset notches 512 corresponds one-to-one with the elastic spring 510. The color plate 513 is fixedly connected to the end of the guide rod 506 and placed inside the indicator part 6. The color plate 513 has a color, and preferably a dark color that is easy to observe. When the end of the elastic spring 510 is placed inside the limiting ring 511, the color plate 513 is close to the surface of the panel 2.

[0036] Under normal conditions, the end of the elastic spring 510 is constrained by the inner wall of the limiting ring 511. At this time, the end of the color plate 513 has a gap with the surface of the panel 2 and is in a slightly retracted state, which is not easily noticeable from the outside. When the moving magnet 505 moves the guide rod 506 upward due to the increase in temperature, the color plate 513 is pushed, and the end of the color plate 513 approaches the indicator part 6 on the surface of the panel 2. The user can intuitively identify the faulty circuit by the color change of the indicator part 6. The end of the elastic spring 510 enters the limiting ring 511 and does not correspond to the reset notch 512. At this time, the position of the color plate 513 is fixed, and the positions of the guide rod 506 and the moving magnet 505 are temporarily locked. Even if the temperature drops after the circuit is disconnected and the magnetic force of the moving magnet 505 is restored, it cannot reset itself. This effectively prevents the circuit from frequently switching on and off (frequency jumping) due to temperature fluctuations when the fault has not been eliminated.

[0037] When it is necessary to reset the moving magnet 505 and the pressure rod 504, remove the panel 2 and manually rotate the limiting ring 511 so that the reset notch 512 corresponds to the elastic spring 510. At this time, the pressure rod 504 is reset due to the repulsive force between the moving magnet 505 and the stationary magnet 507, and the end of the elastic spring 510 slides out of the limiting ring 511. Then, manually rotate the limiting ring 511 at a certain angle so that the reset notch 512 and the elastic spring 510 are misaligned to prevent the elastic spring 510 from automatically resetting after temperature changes.

[0038] More specifically, a traction groove 4021 is provided on one side of the rocker arm 402; a positioning pin 5041 is fixedly connected to the side wall of the pressure rod 504. The positioning pin 5041 can slide along the traction groove 4021. This design allows the upward movement of the pressure rod 504 to drive the rocker arm 402 upward synchronously through the cooperation of the positioning pin 5041 and the traction groove 4021, and to disengage the rocker arm 402 from the input plate 401. There is a certain gap between the positioning pin 5041 and the traction groove 4021 to prevent the pressure rod 504 from swinging and getting stuck. The rotation of the pressure rod 504 can disengage the positioning pin 5041 from the traction groove 4021. Since the side of the pressure rod 504 close to the rocker arm 402 is flat, the pressure rod 504 will not rotate relative to the rocker arm 402 during normal operation. When it is necessary to remove the pressure rod 504, it is necessary to manually rotate the pressure rod 504 so that the positioning pin 5041 can slide out from the traction groove 4021. At the same time, when the pressure rod 504 rotates (for example during adjustment or disassembly), after the pressure rod 504 rotates to a certain angle, the positioning pin 5041 can disengage from the traction slide 4021, making it easy to remove the pressure rod 504 and the entire contact assembly 5 from above the circuit assembly 4 for convenient maintenance.

[0039] It should be noted that the length of the traction slide 4021 is greater than the sliding distance of the positioning pin 5041. Therefore, during use, the positioning pin 5041 will not reach the extreme position at either end of the traction slide 4021. Furthermore, due to the relatively long length of the traction slide 4021, it is also convenient for the positioning pin 5041 to slide out of the traction slide 4021.

[0040] The mounting cover 501 has a guide groove 514. One end of the rocker 402 is placed in the guide groove 514, and the rocker 402 can slide along the guide groove 514. The guide groove 514 guides and limits the movement path of the rocker 402, ensuring the accuracy and stability of its movement.

[0041] Specifically, the mounting cover 501 has an arc-shaped groove 515 in the middle, and the guide sleeve 502 is placed in the arc-shaped groove 515 and can slide along it. This allows the entire pressing sleeve 503 and pressing rod 504 assembly to be adjusted within a certain angle range to adapt to different installation requirements or to achieve different swing directions of the panel 2. The housing 3 has a locking groove 32 corresponding to the position of the mounting cover 501. An elastic limiting member 516 is fixedly connected to the mounting cover 501 at the position corresponding to the locking groove 32. The elastic limiting member 516 is, for example, an elastic buckle with a protrusion. The elastic limiting member 516 can be snapped into the corresponding locking groove 32. When the mounting cover 501 is installed in place, the elastic limiting member 516 can be inserted into the corresponding locking groove 32 to achieve quick snap-fit ​​fixation between the mounting cover 501 and the housing 3, and also facilitates disassembly.

[0042] More specifically, the synchronizing plate 7 has clearance holes 71 at both ends, and the pressure rods 504 pass through the corresponding clearance holes 71. The diameter of the clearance holes 71 is larger than the diameter of the pressure rods 504, ensuring that the movement of the pressure rods 504 is not interfered with by the synchronizing plate 7 during normal operation. A guide rod 72 is fixedly connected to one side of the synchronizing plate 7, and the end of the guide rod 72 penetrates the housing 3. A reset member 73 is sleeved on the outside of each guide rod 72. The reset member 73 is, for example, a compression spring, with one end abutting against the synchronizing plate 7 and the other end abutting against the inner wall of the housing 3. The reset member 73 provides a spring force for the synchronizing plate 7 to reset. When one side is pressed, the synchronizing plate 7 slides along the guide rod 72 and compresses the reset member 73; after being released, the synchronizing plate 7 automatically returns to its original position under the action of the reset member 73.

[0043] When one side of the contact assembly 5 fails, manually rotate the other side's pressing sleeve 503 to slide it relative to the guide sleeve 502. The bottom of the pressing sleeve 503 presses against the synchronization plate 7, pressing both sides of the rocker plates 402 firmly above the corresponding input plate 401. Then, manually rotate the guide rod 506 on the faulty side to slide the positioning pin 5041 on the faulty side out of the corresponding traction groove 4021. Then, manually press the elastic limit member 516 on the faulty side to remove the mounting cover 501, thus removing the contact assembly 5 on the faulty side and preventing the circuit assembly 4 from becoming disordered.

[0044] Specifically, a gripping disc 5031 is fixedly connected to the outer side of the pressing sleeve 503. This disc is used to adjust the relative rotation of the pressing sleeve 503 with respect to the guide sleeve 502, and is used for gripping tools or fingers to adjust the rotation of the pressing sleeve 503 relative to the guide sleeve 502. This facilitates the adjustment of the extension and retraction of the pressing sleeve 503. The pressing sleeve 503 presses the synchronizing plate 7 and the rocker arm 402. A synchronizing sleeve 22 is fixedly connected to the side of the panel 2 near the housing 3. The synchronizing sleeves 22 are respectively fitted onto the ends of the corresponding pressing sleeves 503. When the user presses the panel 2, the synchronizing sleeves 22 ensure that the swing of the panel 2 can be reliably transmitted to the pressing sleeves 503, so that the two move synchronously.

[0045] More specifically, a limiting boss 11 is fixedly connected to the inner side of the outer frame 1, and a limiting notch 21 is opened on the panel 2 corresponding to the position of the limiting boss 11. The limiting notch 21 is engaged with the outer side of the limiting boss 11. During installation, the limiting notch 21 of the panel 2 is engaged with the outer side of the limiting boss 11, thereby restricting the movement of the panel 2 on the outer frame 1 and preventing it from falling off or shifting excessively. A fluorescent part 8 is fixedly installed on the side of the panel 2 away from the housing 3 to facilitate observation of the position of the panel 2. The fluorescent part 8 can be a protrusion, a pit, or a mark with scales, so that users can touch or visually observe the current position of the panel 2 in the dark.

[0046] Specifically, limiting grooves 31 are provided inside the housing 3 at the positions corresponding to the input board 401, the first output board 403, and the second output board 404 to prevent them from shaking. The edges of the circuit board input board 401, the first output board 403, and the second output board 404 are engaged in the corresponding limiting grooves 31, which can effectively prevent them from shaking inside the housing 3 and ensure the reliability of electrical contact. The ends of the mounting cover 501 are in contact with the end faces of the corresponding input board 401, the first output board 403, and the second output board 404. After installation, the ends of the mounting cover 501 are in contact with the end faces of the corresponding input board 401, the first output board 403, and the second output board 404, forming an axial pressing limit on the circuit board to further prevent it from loosening.

[0047] More specifically, the connecting terminal 405 is interference-fitted onto the side of the housing 3 away from the end face. Each connecting terminal 405 is equipped with a bolt for pressing the wire to the corresponding input board 401, first output board 403 and second output board 404. During installation, the core of the external wire is inserted into the connecting terminal 405, and then the bolt is tightened. The end of the bolt is used to press the wire to the terminal of the corresponding input board 401, first output board 403 and second output board 404 to achieve a firm electrical connection. The bolt also allows the connecting terminal 405 to be fixed inside the housing 3.

[0048] In use, connect the wire to the corresponding connection terminal 405 and install the switch in the reserved position. During normal operation, manually press the panel 2 to make the panel 2 flip relative to the frame. Through the limit notch 21, the pressing sleeve 503 and the pressing rod 504, the rocker 402 swings relative to the input plate 401, switching the end of the rocker 402 to contact the first output plate 403 (or the second output plate 404), controlling the switching of the first output plate 403 or the second output plate 404 to connect with the input plate 401.

[0049] When the temperature of circuit component 4 rises due to factors such as current overload, the heat is conducted to the moving magnet 505 through the pressure rod 504. The magnetic force of the moving magnet 505 decreases after heating, weakening the repulsive force between it and the stationary magnet 507. Under the action of the elastic element 508, the moving magnet 505 drives the pressure rod 504 to move towards the stationary magnet 507. Through the cooperation of the positioning pin 5041 and the traction slide 4021, the rocker 402 moves upward synchronously, disengaging from the input plate 401 and triggering circuit component 4 to disconnect the circuit, achieving automatic power-off protection. Simultaneously, the guide rod 506 drives the retaining ring 509 upward synchronously, causing the end of the elastic spring 510 to enter the limiting ring 511 and not correspond to the reset notch 512. The end of the color plate 513 approaches the indicator part 6 on the surface of panel 2 and is fixed in position. The positions of the guide rod 506 and the moving magnet 505 are temporarily locked to prevent the moving magnet 505 from resetting after the temperature drops. At this time, the user can intuitively identify the faulty circuit side through the color change of the indicator part 6.

[0050] After the fault in the downstream equipment of the switch is cleared, the contact assembly 5 needs to be manually reset to make the switch work normally. When manually resetting the contact assembly 5, first remove the panel 2, then manually rotate the limiting ring 511 so that the reset notch 512 corresponds to the elastic spring 510. At this time, under the influence of the repulsive force between the moving magnet 505 and the stationary magnet 507, the pressure rod 504 is reset and the end of the elastic spring 510 slides out from the limiting ring 511. Then manually rotate the limiting ring 511 at a certain angle so that the reset notch 512 and the elastic spring 510 are misaligned. Finally, put the panel 2 back into the outer frame 1. At this time, the color plate 513 is close to the inside of the panel 2 and is not easily noticed from the outside.

[0051] When it is necessary to repair the contact assembly 5 or circuit assembly 4 on the faulty side, manually rotate the pressure sleeve 503 on the non-faulty side. Using a tool or your fingers, hold the pressure sleeve 503 and adjust its rotation relative to the guide sleeve 502. This will cause the pressure sleeve 503 to slide closer to the synchronization plate 7. The bottom of the pressure sleeve 503 will press against the synchronization plate 7, pressing the rocker arms 402 on both sides against the corresponding input plates 401. At this time, the rocker arms 402 are in the middle position, and neither end of them is in contact with the corresponding first output plate 403 or second output plate 404, thus disconnecting the circuit. Then, manually rotate the guide rod 506 on the faulty side to slide the positioning pin 5041 on the faulty side out of the corresponding traction groove 4021. Then, manually press the elastic limit member 516 on the faulty side to remove the contact assembly 5 on the faulty side, thus avoiding structural confusion of the circuit assembly 4. To disassemble circuit assembly 4, the contact assemblies 5 on both sides and the synchronization board 7 need to be removed, and then the various structures of circuit assembly 4 can be removed from the housing 3.
