They play an indispensable role in industrial production, smart homes, kitchen appliances, and other fields. They can flexibly adjust equipment output power or operating status based on actual needs, significantly improving device convenience and applicability, and providing users with diverse operating options. Taking the kitchen appliance egg beater as an example, a multi-speed control switch is widely used to adjust the stirring speed and whipping strength. By rotating the gear switch, users can switch between different speed gears to adapt to the needs of whipping different ingredients such as egg liquid and cream. However, the internal conductive components of the multi-speed control switch of the existing egg beater are not only quite complex in structure design, involving the precise arrangement of multiple contacts, the superposition and combination of multiple layers of conductive sheets, and complex insulation isolation design, but also have many parts, and each conductive point needs to be independently riveted and installed. This series of characteristics directly leads to the entire production process becoming extremely cumbersome, and places extremely high demands on the processing accuracy and assembly tolerance of the parts, which increases the number of steps in the production process and greatly reduces its production efficiency.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. The described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] Example 1: Please see the attached Figure 1-2 The conductive component of the present application includes a conductive component 1 and a shell 3, wherein the conductive component 1 is embedded in the shell 3. The conductive component 1 includes a plurality of independently arranged gear guides 11, auxiliary guides 12, and inertial guides 13, and the plurality of gear guides 11, auxiliary guides 12, and inertial guides 13 are in the same plane. The shell 3 includes a body 31, a movable groove 32, a plurality of first through holes 33, a plurality of second through holes 34, and a plurality of punching holes 35 passing through the body 31; the first through holes 33 are arranged corresponding to the gear guide 11, the second through holes 34 are arranged corresponding to the auxiliary guide 12, and the punching holes 35 are arranged corresponding to the connection points of the plurality of gear guides 11, auxiliary guides 12, and inertial guides 13; the auxiliary guides 12 and inertial guides 13 are passed through the movable groove 32; wherein, the gear guide 11, the auxiliary guide 12, and the inertial guide 13 all have a cut portion 14 protruding toward the corresponding punching hole 35.

[0030] The gear guide plate 11 refers to a metal sheet structure used to establish a basic gear conduction path, and can be specifically formed by copper alloy stamping. Each gear guide plate 11 corresponds to the electrical connection of a specific gear.

[0031] The auxiliary guide plate 12 refers to an additional conductive path for enhancing operating energy. It can be an independent plate made of the same material as the gear guide plate 11. When it is turned on, a parallel circuit is formed to increase the current.

[0032] The inertial guide vane 13 refers to a neutral conductive path that does not change the original energy output and can be manufactured using the same process as the auxiliary guide vane 12 . When conducting, it maintains the main gear current parameters.

[0033] The shell 3 refers to an integrated support structure formed by injection molding the conductor 4, which can be specifically realized by injection molding a thermoplastic conductive resin material followed by curing. Its function is to integrate and fix the conductive component 1 with the mechanical structure, eliminating the positioning deviation caused by traditional separate assembly.

[0034] The movable groove 32 refers to a recessed area opened on the surface of the shell body 31, which can be specifically realized by reserving a slot structure during mold forming. Its function is to provide displacement space for the second connection end 223 of the auxiliary control component 22, thereby realizing the connection between the second connection end 223 and the auxiliary guide vane 12 or the inert guide vane 13.

[0035] The first through hole 33 refers to a hole structure that passes through the shell body 31. Specifically, it can be achieved by setting a corresponding punch in the injection mold to form a hole. Its function is to accurately constrain the installation position of the gear guide 11 and ensure that the first contact end 212 enters the first through hole 33 and is connected with the corresponding gear guide 11, while ensuring that the spacing between adjacent gear guides 11 meets the electrical isolation requirements.

[0036] The second through hole 34 refers to a through hole that matches the position of the auxiliary guide plate 12. It can be specifically realized by simultaneous injection molding with the first through hole 33. Its function is to fix the auxiliary guide plate 12 and maintain its relative position relationship with the gear guide plate 11, ensuring that the second contact end 213 enters the second through hole 34 and connects with the auxiliary guide plate 12.

[0037] The punching hole 35 refers to a hole-like structure provided at the connection point of the guide plates. Specifically, it can be achieved by forming a thin-walled area at the connection point of the conductor 4 during injection molding. Its function is to provide a precise processing reference point for the subsequent punching process to ensure the reliability of the electrical connection between the guide plates.

[0038] The cut portion 14 refers to a structure formed after the tool punches through the punching hole 35 .

[0039] The conductive component in this embodiment is a structure in which the conductor 4 is fixed by injection molding, and then the connecting part of the conductor is punched through the punching hole 35 to form an independent gear guide 11, an auxiliary guide 12 and an inert guide 13, ensuring that the spacing between each guide is uniform and the insulation is reliable. Through this setting, the overall structure is simple, and the existing method of independently installing each individual conductive part in sequence can be avoided, effectively simplifying the production process, simplifying the operation, and thus improving production efficiency. In addition, the production process of this structure has fewer parts, which effectively reduces production costs. The guide is precisely fixed in the through hole of the shell 3 during the injection molding stage, eliminating manual assembly errors, realizing the precise positioning and installation of the guide component, and controlling the spacing error between multiple guides within the range of the injection mold processing accuracy, avoiding guide dislocation caused by manual assembly, and the production process is simple and fast.

[0040] In this structure, the integrated construction of the shell 3 simplifies the production process, allowing the guide vane to be positioned and molded simultaneously with the shell, reducing manual assembly costs. The shift guide vane 11 is fitted and secured to the first through-hole 33. Through the first through-hole 33, the shift guide vane 11 contacts the shift control component. The auxiliary guide vane 12 contacts the shift control component through the second through-hole 34. The auxiliary control component selectively connects to either the auxiliary guide vane 12 or the inertial guide vane 13 via the movable slot 32. This arrangement ensures that the shell 3 provides a stable support structure for the guide vane and maintains stable electrical connection between the guide vane and the control component, ensuring the reliability and durability of the conductive assembly.

[0041] In some embodiments, see the attached Figure 3 The gear guide plate 11 is provided with a first locking hole 111, and the auxiliary guide plate 12 is provided with multiple second locking holes 121; the size of the first locking hole 111 is smaller than the size of the first through hole 33, and the size of the second locking hole 121 is smaller than the size of the second through hole 34.

[0042] Because the size of the first engaging hole 111 is smaller than that of the first through hole 33, the gear guide 11 is able to pass through the first through hole 33. When the first contact 212 moves into the first through hole 33, it can conduct electricity with the corresponding gear guide 11. Similarly, because the size of the second engaging hole 121 is smaller than that of the second through hole 34, the auxiliary guide 12 is able to pass through the second through hole 34. When the second contact 213 moves into the second through hole 34, it can conduct electricity with the auxiliary guide 12, ensuring that the second conductive piece 211 enters the corresponding through hole after rotation. Specifically, the first contact 212 and the second contact 213 can be implemented as protruding semicircular shapes. This configuration allows for precise control of the corresponding gear position. Furthermore, with the first engaging hole 111 and the second engaging hole 121, the first contact 212 can be snapped into the first engaging hole 111, and the second contact 213 can be snapped into the second engaging hole 121, effectively ensuring stable conduction and overall operational reliability.

[0043] In some embodiments, see the attached Figure 4 The shell 3 also includes a blocking block 36, which is connected to the body 31 and is arranged on one side of the second through hole 34. The center point of the blocking block 36 is connected to the center point of the second through hole 34 in an arc shape. The blocking block 36 is used to place the gear control component 21 to disconnect the electrical connection between the gear control component 21 and the conductive component 1.

[0044] Among them, the blocking block 36 refers to a protruding structure connected to the shell body 31, which can be specifically realized by using an injection molding process to be integrally formed with the shell 3. Its spatial position is limited to the side of the second through hole 34, and physical isolation is achieved by blocking the contact path between the gear control component 21 and the conductive component 1.

[0045] The arc-shaped connection refers to the geometric relationship between the center point of the blocking block 36 and the center point of the second through hole 34. It can be achieved by determining the arc parameters through three-dimensional modeling. The arc matches the gear switching trajectory to ensure the precise positioning of the blocking block 36 on the rotation path.

[0046] Specifically, the blocking block 36 is integrated into the main body 31 of the shell 3 near the second through-hole 34, and its arc-shaped positioning feature remains coaxial with the rotation axis of the gear control component 21. When the gear control component 21 is switched to a specific position, its bottom structure is guided to the surface of the blocking block 36. At this time, the conductive contact surface between the gear control component 21 and the conductive component 1 is completely blocked by the blocking block 36. The physical structure of the blocking block 36 forms a physical barrier, preventing the gear control component 21 from making electrical contact with the auxiliary guide 12, thereby disconnecting the circuit. This blocking process does not rely on the deformation reset of the elastic contact member, but directly cuts off the current path through the spatial interference of the rigid structure.

[0047] This solution avoids arcing and poor contact caused by contact-type disconnection through the rigid isolation of blocking block 36, achieving zero-contact control of circuit disconnection during gear shifting, ensuring the stability of the power-off state and avoiding the risk of false triggering. Furthermore, its arc-shaped positioning design uses blocking block 36 as both a physical isolation component and a positioning reference, simplifying the structural layout while ensuring that the blocking block 36 and conductive component 1 always maintain a predetermined distance, improving the reliability of the device.

[0048] Example 2: This embodiment is based on the above embodiment. Figure 5 , provides a method for producing the above conductive component, the steps comprising: Prepare a conductor 4, which includes a connecting portion 41, several gear guides 11, auxiliary guides 12 and inertial guides 13. The connecting portion 41 is connected to the cut portions of different guides and is arranged corresponding to the punching holes 35. The connecting portion 41 is used to connect the several gear guides 11, auxiliary guides 12 and inertial guides 13 to form a whole.

[0049] The conductor 4 is punched out, the holes 35 are punched out correspondingly, and the connecting portion 41 is punched out to form the conductive component 1 .

[0050] The production method in this embodiment directly injects the conductor 4, which, after curing, forms the shell 3. The conductor 4 is embedded in the shell 3, with the connecting portion 41 corresponding to the punched hole 35. A tool is used to punch the connecting portion 41 in the punched hole 35, transforming the connecting portion 41 into the cut portion 14, thereby separating the conductor 4 into the independent position guide 11, auxiliary guide 12, and inertial guide 13. This production process simplifies the production process, requiring only continuous injection molding and punching to complete the production of the conductive assembly. This effectively reduces assembly errors, ensures accurate guide position, and reduces processing steps, lowering processing costs and labor, thereby improving the production efficiency of the multi-position control switch.

[0051] Example 3: This embodiment is based on the above embodiment. Figure 6 , provides a multi-speed control switch, including a conductive component and a control mechanism 2, the conductive component adopts the conductive component as described above, and the conductive component is relatively provided with a first plane 5 and a second plane 6.

[0052] The control mechanism 2 includes a gear control component 21 and an auxiliary control component 22. The gear control component 21 moves on the first plane 5 and is connected to the gear guide vane 11 and the auxiliary guide vane 12 for switching the operating state; the auxiliary control component 22 moves on the second plane 6 and is connected to either the inertial guide vane 13 or the auxiliary guide vane 12; when the auxiliary control component 22 is connected to the auxiliary guide vane 12, the auxiliary control component 22 is used to control the enhancement of the operating energy; when the auxiliary control component 22 is connected to the inertial guide vane 13, the operating state is the operating state when the gear control component 21 is connected to the gear guide vane 11.

[0053] The gear control component 21 in the control mechanism 2 is the mechanical structure that implements the main gear shifting. Specifically, it can be a rotary contact assembly that selects different gear guides 11 through physical contact. The auxiliary control component 22 is an additional energy adjustment module that connects the auxiliary guide 12 or the inertial guide 13 through displacement switching. The punching hole 35 in the production step refers to the cutting area reserved during the injection molding process. Specifically, it can be a mold-formed hole that guides the punching tool to cut the connection between the guides.

[0054] In the multi-speed control switch of this embodiment, the three types of guide plates arranged in parallel in the conductive component 1 are formed into independent conductive units through a punching process. When the gear control component 21 selects a specific gear guide plate 11, the device enters the basic operation mode. If the auxiliary control component 22 is connected to the auxiliary guide plate 12 at this time, an additional conductive path is formed, which increases the total current to achieve energy enhancement; if the inertial guide plate 13 is connected, the original current parameters are maintained. This solution directly changes the conductive path through a mechanical structure, reducing the complexity of the circuit. This structure makes the energy regulation function independent of the gear switching. During operation, the output intensity can be adjusted in real time without changing the original speed, realizing dynamic adjustment of the operating energy under the gear holding state. In the egg beater application, when the user maintains the current speed gear, the whipping force can be temporarily enhanced by switching the auxiliary guide plate 12. The ability to dynamically adjust the whipping parameters according to the characteristics of the food, environmental factors, etc. can be avoided. The sudden change of food properties caused by frequent gear changes further improves the performance of the egg beater, is highly practical, and effectively guarantees the whipping quality.

[0055] In addition, the shift control component 21 moves on the first plane 5, and the auxiliary control component 22 moves on the second plane 6. This structural design is ingenious and compact, and the position design of the shift control component 21 and the auxiliary control component 22 is achieved by using both sides of the conductive component. This not only increases the functional effect and practicality, but also ensures a compact overall structure.

[0056] In some embodiments, see Figure 7 The auxiliary control component 22 includes a first conducting member 221 , a fixing member 224 and a first control member 225 .

[0057] The first conducting member 221 is provided with a first connecting end 222 and a second connecting end 223 opposite to each other, and the second connecting end 223 is connected to the inert guide vane 13 or the auxiliary guide vane 12; the fixing member 224 is provided on both sides of the first connecting end 222 and is used to fix the first connecting end 222; the first control member 225 is in contact with the first conducting member 221 and is provided between the first connecting end 222 and the second connecting end 223, and is used to control the second connecting end 223 to be connected to the inert guide vane 13 or the auxiliary guide vane 12.

[0058] The first conductive member 221 may be formed by stamping an elastic metal sheet, and the conductive path switching is achieved through deformation.

[0059] The fixing member 224 refers to a constraint structure for limiting the displacement of the first connection end 222 . Specifically, a plurality of positioning posts 217 may be used to surround the first connection end 222 to achieve the displacement constraint function.

[0060] The first control member 225 refers to an operating component that drives the first conductive member 221 to move. Specifically, a push rod mechanism can be used to change the shape of the conductive member through mechanical abutment. Its function is to accurately control the conductive switching of the second connection end 223.

[0061] In this embodiment, when increased operating energy is required, the first control member 225 pushes the first conductive member 221 to deform, causing the second connection end 223 to disengage from the inertial guide 13 and contact the auxiliary guide 12. The auxiliary guide 12 then provides additional energy to the circuit. When the basic gear energy is required, the external force exerted by the first control member 225 is removed, causing the first conductive member 221 to rebound, causing the first control member 225 to return to its original position, thereby restoring contact between the second connection end 223 and the inertial guide 13. The energy transfer path remains unchanged. The fixing member 224 secures the first connection end 222 by clamping it, ensuring its stability and enabling the downward pressure of the first control member 225 to cause the second connection end 223 to move, ensuring smooth energy enhancement. It also prevents contact failure caused by mechanical vibration during the conduction process. The first control member 225's abutment position is located between the first and second connection ends 222, 223. This leverage mechanism amplifies the displacement of the control action, ensuring reliable conduction switching.

[0062] This application adds an independently controllable auxiliary guide vane 12 conduction path, increases the energy regulation dimension on the basis of maintaining the gear switching function, enables the equipment operating energy to be adjusted in real time according to the actual working conditions, and realizes dynamic control of the operating energy during the gear switching process, avoiding the problem of equipment performance limitation caused by fixed energy output.

[0063] In kitchen appliance applications, when the whisk is switched to high speed, the auxiliary guide blade 12 provides additional energy to accelerate the whipping process. When the ingredients are close to the ideal state, the auxiliary guide blade 12 can be disconnected to reduce the energy output and prevent over-whipping. This dynamic adjustment mechanism effectively solves the technical defect of traditional switches that cannot adjust the energy output when the gear is fixed.

[0064] Preferably, a side of the first control member 225 close to the first connection end 222 abuts against the first conducting member 221 .

[0065] Specifically, the first control member 225 contacts the first conductive member 221 at a position close to the first connection end 222, and a force is applied through the contact point during operation. Since the first connection end 222 has been restricted by the fixing member 224, the first conductive member 221 rotates with this end as the fulcrum, and the second connection end 223 moves accordingly and disengages from the inert guide plate 13, making contact with the auxiliary guide plate 12. The abutment point forms a short lever arm structure close to the fulcrum, so that a small displacement of the first control member 225 can drive the second connection end 223 to produce a larger stroke, thereby ensuring that the first conductive plate is in full contact with the target guide plate. This structure reduces the elastic deformation of the first conductive member 221 when subjected to force, so that the contact pressure distribution between the second connection end 223 and the auxiliary guide plate 12 is more uniform, avoiding the increase in contact resistance caused by local stress concentration.

[0066] The present application significantly improves the displacement accuracy of the second connection end 223 under the same operating stroke by shortening the lever arm length, making the conduction state switching action of the auxiliary control component 22 more accurate and reliable. In scenarios where kitchen appliances such as egg beaters require frequent switching of energy levels, energy output fluctuations caused by insufficient contact pressure can be effectively avoided, ensuring that the whipping function can stably switch between the enhanced level and the conventional level, thereby solving the problem of over- or under-whipping of ingredients.

[0067] In some embodiments, see Figure 8-9 The gear position control component 21 includes a second conducting piece 211 , a conducting shaft 214 , a third conducting piece 215 and a second control component 216 .

[0068] The second conducting piece 211 is provided with a first contact end 212 and a second contact end 213. The first contact end 212 is connected to the gear guide piece 11, and the second contact end 213 is connected to the auxiliary guide piece 12. The central axis of the first contact end 212 coincides with the central axis of the second contact end 213; the conducting shaft 214 is movably connected to the other end of the second conducting piece 211; the third conducting piece 215 is connected to the end of the conducting shaft 214 away from the second conducting piece 211, and is used to be connected to the wire; the second control component 216 is fixedly connected to the second conducting piece 211, and the conducting shaft 214 is provided through the second control component 216, and is used to control the second conducting piece 211 to be connected or disconnected with the corresponding gear guide piece 11.

[0069] The second conductive piece 211 can be specifically implemented by a double-contact spring formed by stamping copper alloy, and the first contact end 212 and the second contact end 213 are arranged so that the central axis thereof coincides with each other, thereby ensuring uniform distribution of contact pressure.

[0070] The conducting shaft 214 is a component that transmits mechanical motion and maintains a conductive path. Specifically, it can be implemented by a metal shaft with a silver-plated surface. Its movable connection design allows the second conducting piece 211 to rotate around the axis to switch the contact position.

[0071] The third conducting piece 215 refers to a fixed conductive interface connected to an external wire, and can be specifically implemented by a riveted terminal. Its direct connection with the conducting shaft 214 can reduce the contact resistance in the current transmission path.

[0072] The second control member 216 refers to an operating mechanism for driving the second conductive piece 211 to move, and can be implemented by a combination of an injection-molded knob and a metal sleeve. Its fixed connection through the conductive shaft 214 can ensure movement synchronization.

[0073] In this embodiment, when the second control member 216 is rotated, the conductive shaft 214 extending therethrough drives the second conductive piece 211 to rotate about its axis, causing the first contact 212 to disengage from the current gear guide 11 and move to the target gear guide 11 position. Because the central axes of the first contact 212 and the second contact 213 coincide, the second conductive piece 211 maintains contact between the first contact 212 and the gear guide 11, and the second contact 213 and the auxiliary guide 12, during rotation, ensuring synchronous contact and stable connection. The flexible connection between the conductive shaft 214 and the second conductive piece 211 allows them to form a stable conductive path during rotation. Simultaneously, the third conductive piece 215 connects the external wire to the circuit via the conductive shaft 214, ensuring the continuity of the current transmission path. The fixed connection between the second control member 216 and the second conductive piece 211 eliminates relative displacement between the components, ensuring precise correspondence between the contact switching action and the operational input.

[0074] This solution utilizes a dual-contact structure with overlapping central axes to ensure that the contact pressure on both sides of the conductive plate is always balanced during rotational switching, effectively eliminating the risk of contact surface deviation. Furthermore, in existing technologies, the control component and conductive plate often use a separate linkage structure, which can cause operation delays due to assembly errors. However, this solution's through-type fixed connection design achieves direct synchronization between the operating mechanism and the conductive component 1, improving the operational accuracy and electrical connection reliability of gear switching, and significantly enhancing the switching response accuracy.

[0075] In some embodiments, see Figure 10 The second control member 216 is provided with a positioning column 217 and a limiting block 218 . The positioning column 217 is passed through the second conductive piece 211 , and the limiting block 218 is provided on both sides of the second conductive piece 211 .

[0076] The positioning column 217 refers to a columnar structure that passes through the second conductive piece 211 , and can be specifically implemented by a cylinder made of metal or engineering plastic, and is used to constrain the second conductive piece 211 .

[0077] The limit block 218 refers to a block-shaped constraint structure arranged on both sides of the second conductive piece 211. Specifically, it can be implemented by a protruding structure integrally formed with the second control member 216. It maintains a gap with the side of the second conductive piece 211 and is used to limit the displacement of the second conductive piece 211 in a direction perpendicular to the rotation plane.

[0078] Specifically, the positioning post 217 is inserted into the second conductive piece 211. When the second conductive piece 211 rotates about the conductive axis 214, the positioning post 217 ensures the stable rotation of the second conductive piece 211, preventing the second conductive piece 211 from shifting and misaligning the contact with the gear guide piece 11 due to the shifting center of rotation. This improves the conduction accuracy between the first contact 212 and the second contact 213 and the guide piece. The limit blocks 218 are symmetrically distributed on both sides of the second conductive piece 211, forming a gap of 0.1-0.5 mm with the side walls of the second conductive piece 211, allowing rotational freedom while limiting lateral displacement. During the switching process, the second conductive piece 211 is doubly constrained by the positioning post 217 and the limit blocks 218, and its motion trajectory is confined to a single rotation plane, eliminating unexpected swing caused by mechanical vibration.

[0079] By adding a limit block 218 to form a bilateral constraint, the freedom of motion of the conductive piece is limited from two-dimensional planar motion to a single rotational motion, effectively reducing the impact of component wear on contact stability. This allows for precise positioning of the second conductive piece 211 during gear switching, ensuring that its contact surface with the gear guide piece 11 always remains completely overlapped. In egg beater applications, the operator can obtain a clear sense of gear positioning when rotating the control, avoiding accidental short circuits or poor contact between different gears due to conductive piece offset, making the stirring head speed switching more stable and improving the uniformity of food mixing.

[0080] In some embodiments, the second control member 216 is provided with a protrusion 219 , the upper end of the protrusion 219 abuts against the second conductive piece 211 to lift the second conductive piece 211 for easy rotation.

[0081] The bump 219 is a local protrusion extending from the surface of the second control member 216. Specifically, it can be implemented as an arc-shaped protrusion, a wedge-shaped block, or a rectangular parallelepiped. Its top end forms point, line, or surface contact with the lower surface of the second conductive piece 211. The geometric shape of the contact surface adjusts the tilt angle of the second conductive piece 211. The bump 219 is provided between the corresponding limit blocks 218.

[0082] Raising the second conductive piece 211 means applying an upward force to the conductive piece through the protrusion 219 to reduce the contact pressure between it and the gear guide piece 11. Specifically, the lifting amplitude can be adjusted by changing the height or tilt angle of the protrusion 219, thereby controlling the friction between the conductive piece and the guide piece.

[0083] Specifically, when the operator rotates the second control member 216, the relative position of the contact area between the top of the protrusion 219 and the second conductive plate 211 changes. At this point, the protrusion 219 exerts an upward lifting force on the conductive plate. This lifting force causes the second conductive plate 211 to deflect slightly around its connection point with the conductive shaft 214, creating a lever effect. During this process, the contact pressure between the second conductive plate 211 and the gear guide plate 11 is partially offset, reducing sliding friction resistance. At the same time, the deflection trajectory of the second conductive plate 211 is limited to the range of motion of the top of the protrusion 219, ensuring that the conductive plate maintains stable contact with the target gear guide plate 11 after lifting, avoiding electrical connection failure due to excessive separation.

[0084] The present application decomposes the rotational action into a composite motion of lifting and deflection through the structure of the protrusion 219, thereby reducing friction while maintaining the stability of the electrical contact, solving the problem of operational jamming, and realizing low-resistance rotation of the conductive piece during gear switching, thereby avoiding the difficulty of operation caused by excessive friction, and at the same time ensuring a reliable electrical connection between the second conductive piece 211 and the guide piece, thereby improving the operational smoothness and service life of the switch.

[0085] In some embodiments, the guide shaft 214 is a hollow guide shaft 214 .

[0086] The hollow conducting shaft 214 refers to a hollow structure that is provided inside the shaft body and runs through the axial direction. Specifically, it can be formed by stamping or cutting a metal pipe. The hollow structure reduces the amount of material used and forms a current transmission channel.

[0087] Specifically, the hollow conducting shaft 214 is designed as a tubular structure, and its internal cavity forms a continuous channel in the direction of the shaft extension. When the second conducting piece 211 and the third conducting piece 215 are respectively connected to the two ends of the hollow conducting shaft 214, the second conducting piece 211 and the third conducting piece 215 are connected. Compared with the existing technology, the traditional conducting shaft 214 adopts a solid metal rod structure, which is more bulky and has a higher material cost. The hollow structure of the hollow conducting shaft 214 is relatively light, and the material cost is much lower than that of a solid shaft. In addition, the heat dissipation of the solid shaft in the existing technology relies on external heat sinks, while the cavity of the hollow conducting shaft 214 can form an air convection channel, accelerating the dissipation of heat from the inside of the shaft.

Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0090] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted.
