Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a switching device. Background Technology

[0002] A switching device is an electrical device used to control the on / off state of a circuit. It changes the connection mode of contacts based on user operation, thereby controlling the circuit in which the switching device operates. Switching devices typically include a panel and a lever. The lever extends from the panel, and the user can operate the lever to change the state of the switching device.

[0003] However, the design of the switching devices is not reasonable enough, which makes the panels and levers of the switching devices easy to be damaged, and may even affect the normal operation of other structures in the switching devices. Utility Model Content

[0004] This application provides a switching device that can reduce the possibility of damage to the panel and toggle lever, and improve the reliability of the switching device.

[0005] This application provides a switching device with a first orientation. The switching device includes a panel, a partition, a contact assembly, a support member, and a lever. The panel, partition, and contact assembly are distributed along the first orientation. The panel has a first mounting hole, and the partition has a locking plate that is fitted into the first mounting hole. The support member is located on the side of the partition facing away from the panel, and the side of the support member facing away from the panel cooperates with the contact assembly. The support member is used to control the switching of the working state of the contact assembly. The locking plate has a second mounting hole, and the lever is connected to the side of the support member facing the panel and extends out of the panel through the second mounting hole. The support member and the lever are integrally formed.

[0006] In this embodiment, the connection between the support and the lever is relatively reliable, which can reduce the damage caused by the lever becoming loose or separating from the support due to the toggle operation. Furthermore, the partition plate positioned between the support and the panel can further reduce the possibility of panel damage, thereby improving the reliability of the switching device.

[0007] Optionally, the lever is made of metal and the support is made of plastic.

[0008] In this way, the lever and the support can be integrally molded by injection molding, which makes the connection between the metal lever and the plastic support stronger and reduces the possibility of breakage at the connection between the lever and the support.

[0009] Optionally, the switching device further includes a pressure plate disposed between the partition and the contact assembly, and a support member rotatably connected to the pressure plate so that the support member can switch between a first position and a second position. When the support member is in the first position, the contact assembly is in a first operating state, and when the support member is in the second position, the contact assembly is in a second operating state.

[0010] With the above configuration, the support can be installed in the switching device via a pressure plate, so that when the lever receives a toggle operation, it can drive the support to rotate, thereby realizing the switching of the contact assembly between different working states.

[0011] Optionally, the partition includes base blocks and mounting blocks distributed and connected to each other along the axial direction of the second mounting hole. The surface of the mounting block facing the panel is curved, the mounting platform is connected to the curved surface, and the base block is connected to the support. The dimension of the mounting platform on the side closer to the mounting block is larger than the dimension of the mounting platform on the side farther away from the mounting block. When the support rotates, different parts of the mounting platform are embedded in the first mounting hole.

[0012] This reduces interference between the partition and the panel, restricting the rotation of the card slot and thus limiting the possible effect of the support on the contact assembly.

[0013] Optionally, the support member has a snap-fit ​​hole on the side facing the base block, and the base block has a snap-fit ​​strip on the side facing the support member, the snap-fit ​​strip engaging with the snap-fit ​​hole. Alternatively, the support member has a snap-fit ​​block on the side facing the base block, and the base block has a snap-fit ​​groove on the side facing the support member, the snap-fit ​​block engaging with the snap-fit ​​groove.

[0014] With the above settings, the support and the base block can be connected in different ways, which can improve the flexibility of the connection between the support and the base block.

[0015] Optionally, a first limiting platform and a second limiting platform are provided at intervals on the side of the pressure plate facing the panel. When the support is in the first position, the support abuts against the first limiting platform, and when the support is in the second position, the support abuts against the second limiting platform.

[0016] Thus, after the support rotates to the point where the contact assembly successfully switches to the working state, the support can abut against the first or second limiting stage to prevent the support from continuing to rotate and potentially damaging the contact assembly.

[0017] Optionally, the support includes an interconnected body and a mating part, with the lever located on the side of the body opposite to the mating part. The pressure plate has a mounting hole, through which the mating part passes and mates with the contact assembly.

[0018] In this way, the mating part can extend to the side where the contact assembly is located, and the support member can mate with the contact assembly through the mating part. When the support member rotates, the support member can control the contact assembly through the mating part to switch the working state of the contact assembly.

[0019] Optionally, the contact assembly includes a first stationary contact, a second stationary contact, and a swing plate. The first and second stationary contact are spaced apart, and the swing plate is located between the first and second stationary contact. The swing plate engages with a mating part, and a support member is used to drive the swing plate to move relative to the first stationary contact through the mating part. When the contact assembly is in a first operating state, the swing plate is in contact with the first stationary contact; when the contact assembly is in a second operating state, the swing plate is in contact with the second stationary contact.

[0020] In this configuration, the contact assembly can engage with the support via a swing plate. The support can drive the swing plate to move through the mating part, allowing the swing plate to contact different parts of the contact assembly, thereby changing the flow of current in the switching device.

[0021] Optionally, the contact assembly includes a fixed contact and a movable contact. The fixed contact is located on the side of the partition facing away from the panel, and the movable contact cooperates with a support member. When the support member rotates, it can drive the movable contact to move, so that the movable contact can contact or separate from the fixed contact.

[0022] In this configuration, the moving contact can control the circuit containing the switching device based on a toggle operation.

[0023] Optionally, the switching device also includes a base housing, which is connected to the panel and encloses the panel to form an installation space. The partition, contact assembly, and support are all located within the installation space.

[0024] In this way, the panel and the bottom shell can protect the partitions, contact assemblies and supports inside the installation space, reducing the possibility of damage to the partitions, contact assemblies and supports by external forces. Attached Figure Description

[0043] The switching device 100 provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, this application provides a switching device 100. The switching device 100 has a first direction X and includes a panel 10, a partition 20, a contact assembly 30, a support member 40, and a lever 50. The panel 10, partition 20, and contact assembly 30 are distributed along the first direction X. The panel 10 is provided with a first mounting hole 101. The partition 20 is provided with a locking platform 21, which is embedded in the first mounting hole 101. The support member 40 is provided on the side of the partition 20 opposite to the panel 10. The side of the support member 40 opposite to the panel 10 cooperates with the contact assembly 30, and the support member 40 is used to control the switching of the working state of the contact assembly 30. The locking platform 21 is provided with a second mounting hole 211. The lever 50 is connected to the side of the support member 40 facing the panel 10 and extends out of the panel 10 through the second mounting hole 211. The support member 40 and the lever 50 are integrally formed.

[0045] In this embodiment, the lever 50 can pass through the mounting plate 21 on the partition 20 via the second mounting hole 211 and extend out of the panel 10. Thus, the lever 50 can serve as a component of the switching device 100 for receiving user operations, and can drive the support member 40 to move based on the toggle operation. In turn, the support member 40 can control the contact assembly 30 to switch working states, thereby realizing the function of the switching device 100.

[0046] The support member 40 and the lever 50 are integrally formed, which makes the connection between the support member 40 and the lever 50 stronger. This can improve the reliability of the support member 40's control over the contact assembly 30 when the lever 50 receives a toggle operation. It also reduces the possibility that the reliability of the connection between the lever 50 and the support member 40 will decrease due to excessive force during the toggle operation or frequent toggle operation, which could lead to the lever 50 becoming loose or even detaching from the support member 40. This would make it difficult for the lever 50 to control the contact assembly 30 to switch working states through the support member 40.

[0047] Furthermore, in this application, the partition 20 is located between the support member 40 and the panel 10, and the partition 20 can provide a certain degree of support for the panel 10. After long-term use of the switching device 100, if the portion of the panel 10 opposite to the support member 40 collapses, the partition 20 and the retaining plate 21 on the partition 20 will support the panel 10, reducing the possibility of excessive collapse of the panel 10 causing damage, or even affecting the normal operation of the support member 40 or other components.

[0048] In summary, in this embodiment, the connection between the support member 40 and the lever 50 is relatively reliable, which can reduce the damage caused by the lever 50 becoming loose due to tossing operations or separating from the support member 40. Furthermore, the partition 20, positioned between the support member 40 and the panel 10, can further reduce the possibility of damage to the panel 10. Therefore, in this application, the structure of the switching device 100 is reasonably designed, reducing the likelihood of damage to the lever 50 and the panel 10, thereby improving the reliability of the switching device 100.

[0049] In some embodiments, the lever 50 may be a metal part and the support 40 may be a plastic part.

[0050] Thus, the lever 50 can be made of metal, while the support 40 can be made of plastic. The lever 50 and the support 40 can be integrally molded by injection molding, which results in a strong connection between the metal lever 50 and the plastic support 40, reducing the possibility of breakage at the connection point.

[0051] The metal material has high strength, which allows the lever 50 to withstand large or frequent tossing operations, reducing the possibility of breakage or damage due to tossing operations. The support 40 is made of plastic, which makes it insulating and reduces the possibility of leakage when the support 40 is in contact with the contact assembly 30.

[0052] It should be noted that, in this embodiment, the material of the lever 50 can be aluminum alloy, copper, stainless steel, etc., and this embodiment does not specifically limit the material of the lever 50.

[0053] In the embodiments of this application, the material of the support member 40 may be polycarbonate (PC), acrylonitrile butadiene styrene copolymer (ABS), or polyamide (PA), etc., and this application does not make any specific limitation.

[0054] It should also be noted that, in order to reduce the possibility of stress and cracks at the position of the support 40 near the lever 50, the lever 50 can be heated first during the injection molding process. Then, the heated lever 50 can be placed in the mold, and finally, injection molding can be performed to form an integrated composite product. Specifically, to ensure that the lever 50 can be properly placed into the mold, an interface can be pre-reserved in the mold. Injection molding can then be performed after the lever 50 is installed at the interface, reducing the possibility of the lever 50 wobbling within the mold during the injection molding process.

[0055] In addition, in this embodiment, the lever 50 extends beyond the panel 10 to receive toggle operations and is directly exposed to the outside of the switching device 100. To ensure better consistency in the appearance of the switching device 100, the lever 50 can be polished, painted, or anodized to make its color more consistent with the panel 10. Of course, levers 50 in other colors can also be made according to usage scenarios and requirements.

[0056] In some embodiments, such as Figure 1 and Figure 3 As shown, the switching device 100 may further include a base shell 70, which is connected to the panel 10 and encloses the panel 10 to form an installation space. The partition 20, the contact assembly 30, and the support member 40 are all located in the installation space.

[0057] Thus, the panel 10 and the base shell 70 can be combined to form the housing of the switching device 100, and a space can be formed between the panel 10 and the base shell 70 for mounting the partition 20, the contact assembly 30, and the support member 40. In this way, the panel 10 and the base shell 70 can protect the partition 20, the contact assembly 30, and the support member 40 inside the mounting space, reducing the possibility of damage to the partition 20, the contact assembly 30, and the support member 40 from external forces.

[0058] In some embodiments, such as Figure 1 and Figure 3 As shown, the switching device 100 may further include a pressure plate 60, which is disposed between the partition 20 and the contact assembly 30. A support member 40 is rotatably connected to the pressure plate 60 so that the support member 40 can switch between a first position and a second position. When the support member 40 is in the first position, the contact assembly 30 is in a first working state; when the support member 40 is in the second position, the contact assembly 30 is in a second working state.

[0059] With the above configuration, the support member 40 can be installed in the switching device 100 via the pressure plate 60. Since the support member 40 is rotatably connected to the pressure plate 60, after the lever 50 receives a toggle operation, the lever 50 can drive the support member 40 to rotate, allowing the support member 40 to switch between a first position and a second position. Simultaneously, the support member 40 can also drive the contact assembly 30 to move, thereby enabling the contact assembly 30 to switch between different operating states.

[0060] Specifically, such as Figure 1 , Figures 3 to 5 As shown, a connecting plate 65 can be provided on the side of the pressure plate 60 facing the panel 10. A rotating hole 602 can be provided on the connecting plate 65. A rotating shaft 43 can be provided on the side of the support member 40 facing the connecting plate 65. The rotating shaft 43 can be embedded in the rotating hole 602 to realize the rotating connection between the support member 40 and the pressure plate 60.

[0061] The rotating shaft 43 and the rotating hole 602 can be configured in different ways. For example, the rotating shaft 43 can be cylindrical, and the rotating hole 602 can be a circular hole. Or, as... Figure 4 and Figure 5 As shown, the rotating shaft 43 can also be a shaft with a teardrop-shaped cross-section, including a semi-cylindrical shaft and a triangular prism shaft connected to each other, and the side of the triangular prism shaft facing away from the semi-cylindrical shaft is an arc surface. Correspondingly, the rotating hole 602 has the same shape as the rotating shaft 43, both being teardrop-shaped, but the size of the rotating hole 602 is larger than the size of the rotating shaft 43.

[0062] When the rotating shaft 43 is a shaft with a cross-section similar to a teardrop shape, in order to ensure that the rotating shaft 43 and the rotating hole 602 can be correctly engaged to realize the rotational connection of the support member 40, a pre-compressed elastic member can also be provided between the support member 40 and the contact assembly 30, or between the support member 40 and the bottom shell 70, so that the triangular prism shaft part of the rotating shaft 43 can cooperate with the rotating hole 602.

[0063] In the above-described manner, to ensure that the lever 50 remains in its current position after receiving a toggle operation, and that the contact assembly 30 remains in its current working state, a limiting structure can be provided between the base block 22 and the mating wall. The limiting function can be implemented through snap-fit, magnetic attraction, or other methods; similar structures in related technologies can be referenced, and will not be elaborated further in this embodiment.

[0064] Of course, in addition to the above-mentioned methods, the support member 40 can also have other configuration methods. For example, the support member 40 can be rotatably connected to the bottom shell 70, or slidably installed on the pressure plate 60, etc. The specific configuration method of the support member 40 is not specifically limited in this embodiment.

[0065] The following description uses the example of the support member 40 being rotatably connected to the pressure plate 60. Other methods can be referred to in the following description.

[0066] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the partition 20 is connected to the support member 40. With this configuration, after the lever 50 receives a toggle operation, the support member 40 can drive the partition 20 to rotate, thereby changing the relative position of the partition 20 and the panel 10. At this time, the mounting plate 21 can also rotate with the partition 20, changing the position of the mounting plate 21 relative to the first mounting hole 101.

[0067] In order to reduce the interference between the partition 20 and the panel 10 when the partition 20 rotates, which would restrict the rotation of the card table 21 and thus limit the possible effect of the support member 40 on the contact assembly 30, the present application also made the following design to the partition 20.

[0068] like Figure 2 and Figure 7 As shown, the partition 20 includes base blocks 22 and mounting blocks 23 distributed and connected to each other along the axial direction of the second mounting hole 211. The surface of the mounting block 23 facing the panel 10 is curved, and the mounting plate 21 is connected to the curved surface. When the support member 40 rotates, different parts of the curved surface are opposite to the first mounting hole 101.

[0069] Thus, when the axis of the second mounting hole 211 is parallel to the axis of the first mounting hole 101, the distance between the mounting block 23 and the panel 10 varies at different points on the surface of the mounting block 23 facing the panel 10. Furthermore, for the surface of the mounting block 23 facing the panel 10, the distance between the portion farther from the axis of the second mounting hole 211 and the panel 10 is larger than the portion closer to the axis of the second mounting hole 211. Therefore, the curved surface design provides more rotation space for the partition 20, reducing the possibility of interference between the partition 20 and the panel 10 after rotation.

[0070] The connection between the card holder 21 and the curved surface can be rounded to reduce the possibility of stress concentration between the card holder 21 and the mounting block 23, and to reduce the possibility that the transition between the card holder 21 and the mounting block 23 is too abrupt when installing the partition 20, which may easily scratch the staff or other parts.

[0071] In addition, such as Figure 2 and Figure 7As shown, the size of the mounting platform 21 closer to the mounting block 23 can be larger, while the size of the mounting platform 21 farther from the mounting block 23 can be smaller. This allows the mounting platform 21 to form a shape similar to a frustum. When the partition 20 rotates relative to the panel 10, different parts of the mounting platform 21 can be fitted into the first mounting hole 101, which can restrict the rotation of the mounting platform 21 and reduce the possibility of the mounting platform 21 wobbling. At the same time, the mounting platform 21 can also block the first mounting hole 101, reducing the possibility of external dust and other debris entering the installation space.

[0072] In addition, the mounting bracket 21 and the first mounting hole 101 can also enable the mounting bracket 21 to continuously support the panel 10, thereby reducing the possibility of the panel 10 being suspended below and thus easily collapsing.

[0073] In this embodiment, the support member 40 and the partition 20 can be connected by a snap-fit ​​mechanism. This facilitates both the assembly of the support member 40 and the partition 20 and the maintenance and repair of either the support member 40 or the partition 20. Specifically, the support member 40 and the partition 20 can be snap-fitted together in different ways, as described below.

[0074] like Figure 6 and Figure 7 As shown, the support member 40 has a snap-fit ​​hole 401 on the side facing the base block 22, and the base block 22 has a snap-fit ​​strip 24 on the side facing the support member 40. At this time, when connecting the support member 40 and the partition plate 20, the snap-fit ​​strip 24 can be embedded in the snap-fit ​​hole 401, so that the snap-fit ​​strip 24 snaps into the snap-fit ​​hole 401.

[0075] Alternatively, the support member 40 may have a snap-fit ​​block on the side facing the base block 22, and the base block 22 may have a snap-fit ​​groove on the side facing the support member 40. In this case, when connecting the support member 40 and the partition plate 20, the snap-fit ​​block can be embedded in the snap-fit ​​groove, and the snap-fit ​​block can snap into the snap-fit ​​groove.

[0076] When the support member 40 and the base block 22 are engaged via snap-fit ​​holes 401 and snap-fit ​​strips 24, the number of snap-fit ​​holes 401 and snap-fit ​​strips 24 can be multiple, such as 2, 3, or 4. When the support member 40 and the base block 22 are engaged via snap-fit ​​blocks and snap-fit ​​slots, the number of snap-fit ​​blocks and snap-fit ​​slots can be multiple, such as 2, 3, or 4. This improves the strength of the engagement between the partition plate 20 and the support member 40.

[0077] Of course, when the support member 40 and the base block 22 are engaged through the snap-fit ​​hole 401 and the snap-fit ​​strip 24, the number of snap-fit ​​holes 401 and snap-fit ​​strips 24 can also be one. When the support member 40 and the base block 22 are engaged through the snap-fit ​​block and the snap-fit ​​groove, the number of snap-fit ​​blocks and snap-fit ​​grooves can also be one. In this respect, the embodiments of this application do not make specific limitations.

[0078] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the support member 40 may include a body 41 and a mating part 42 connected to each other. The lever 50 is located on the side of the body 41 away from the mating part 42. The pressure plate 60 is provided with an assembly hole 601. The mating part 42 passes through the assembly hole 601 and mates with the contact assembly 30.

[0079] Thus, the mating part 42 can extend to the side where the contact assembly 30 is located, and the support member 40 can engage with the contact assembly 30 through the mating part 42. When the support member 40 rotates, the support member 40 can control the contact assembly 30 through the mating part 42 to switch the working state of the contact assembly 30.

[0080] In the embodiments of this application, the contact assembly 30 has different configuration methods, and the following two examples will be used for specific description.

[0081] In one configuration, the contact assembly 30 includes a fixed contact and a movable contact. The fixed contact is fixed to the base shell, and the movable contact cooperates with the support member 40. In this configuration, the support member 40 can drive the movable contact to move, causing the movable contact to contact the fixed contact, thereby connecting the circuit containing the switching device 100. Alternatively, the movable contact can be separated from the fixed contact to disconnect the circuit containing the switching device 100.

[0082] In the case where the switching device 100 also includes a base housing 70, the fixed contact can be fixed to the base housing 70. The movable contact can be movably disposed on the base housing 70, or the movable contact can be made of a deformable material, with one end of the movable contact fixed to the base housing 70 and the other end cooperating with the support member 40.

[0083] In this configuration (Method 1), the moving contact can control the circuit containing the switching device 100 based on a toggle operation. In this case, the switching device 100 can be a single-pole switch, meaning that only one switching device 100 is needed to control the on / off state of a circuit.

[0084] In the second method, the contact assembly 30 includes a first stationary contact 31, a second stationary contact 32, and a swing plate 33. The first stationary contact 31 and the second stationary contact 32 are spaced apart, and the swing plate 33 is located between the first stationary contact 31 and the second stationary contact 32. The swing plate 33 cooperates with the mating part 42, and the support member 40 is used to drive the swing plate 33 to move relative to the first stationary contact 31 through the mating part 42.

[0085] In this configuration, the contact assembly 30 can cooperate with the support member 40 via the swing plate 33. The support member 40 can drive the swing plate 33 to move via the mating part 42, allowing the swing plate 33 to contact different parts of the contact assembly 30, thereby changing the flow pattern of current in the switching device 100. When the contact assembly 30 is in the first operating state, the swing plate 33 is in contact with the first stationary contact 31; when the contact assembly 30 is in the second operating state, the swing plate 33 is in contact with the second stationary contact 32.

[0086] When the contact assembly 30 is in the first operating state and current flows through the switching device 100, the current can flow between the swing plate 33 and the first stationary contact 31 without passing through the second stationary contact 32. That is, the swing plate 33 is connected to the first stationary contact 31, while an open circuit is formed between the swing plate 33 and the second stationary contact 32. When the contact assembly 30 is in the second operating state and current flows through the switching device 100, the current can flow between the swing plate 33 and the second stationary contact 32 without passing through the first stationary contact 31. That is, the swing plate 33 is connected to the second stationary contact 32, while an open circuit is formed between the swing plate 33 and the first stationary contact 31.

[0087] In this configuration (Method 2), the oscillating plate 33 can control the current flow in the circuit containing the switching device 100 based on a toggle operation. In this case, the switching device 100 can be a two-way switch; in application, two switching devices 100 can work together to control the on / off state of a circuit or the switching of an electrical device.

[0088] For ease of explanation, the following description will use the second configuration as an example to illustrate the cooperation between the contact assembly 30 and the mating part 42. The cooperation between the contact assembly 30 and the support member 40 in the first configuration can be referred to the following description. The embodiments of this application will not be repeated here.

[0089] The mating part 42 has a mating groove 421 at the end opposite to the lever 50, and part of the swing plate 33 is embedded in the mating groove 421, such as Figure 3 and Figure 5 As shown. In this way, the mating part 42 and the swing piece 33 can be mated, so that the swing piece 33 can move based on the rotation of the support member 40.

[0090] It should be noted that the oscillating plate 33 may have a moving contact, the first stationary contact plate 31 may have a first stationary contact, and the second stationary contact plate 32 may have a second stationary contact. When the oscillating plate 33 contacts the first stationary contact plate 31, specifically, the moving contact contacts the first stationary contact; when the oscillating plate 33 contacts the second stationary contact plate 32, specifically, the moving contact contacts the second stationary contact.

[0091] In order to reduce the impact of the groove wall of the mating groove 421 on the contact between the swing plate 33 and the first stationary contact plate 31, or the contact between the swing plate 33 and the second stationary contact plate 32, the position of the swing plate 33 that mates with the mating groove 421 can be offset from the moving contact.

[0092] Of course, the mating part 42 and the swing piece 33 can also be mated in other ways. For example, a slot can be provided on the swing piece 33, and the mating part 42 can be embedded in the slot, etc. The specific mating method of the swing piece 33 and the mating part 42 is not specifically limited in this embodiment.

[0093] In addition, in this embodiment, the pressure plate 60 can also limit the rotation angle of the support member 40, reducing the possibility of damage to the contact assembly 30 due to excessive rotation angle of the support member 40. Figure 2 , Figure 3 and Figure 4 As shown, the pressure plate 60 is provided with a first limiting platform 61 and a second limiting platform 62 at intervals on the side facing the panel 10. When the support member 40 is in the first position, the support member 40 can abut against the first limiting platform 61, and when the support member 40 is in the second position, the support member 40 can abut against the second limiting platform 62.

[0094] Thus, after the support member 40 rotates to the point where the contact assembly 30 successfully switches to the working state, the support member 40 can abut against the first limiting platform 61 or the second limiting platform 62 to prevent the support member 40 from continuing to rotate and potentially damaging the contact assembly 30.

[0095] In the case where the support member 40 includes a base block 22 and a mounting block 23, the base block 22 may abut against the first limiting platform 61 or the second limiting platform 62 to limit the rotation angle of the support member 40.

[0096] It should be noted that, in order to ensure that the first limiting platform 61 and the second limiting platform 62 can effectively limit the rotation angle of the support member 40, the size of the first limiting platform 61 can be greater than or equal to the size of the position on the base block 22 opposite to the first limiting platform 61, and the size of the second limiting platform 62 can be greater than or equal to the size of the position on the base block 22 opposite to the second limiting platform 62.

[0097] In some embodiments, such as Figure 4As shown, the pressure plate 60 may also be provided with a first boss 63 and a second boss 64. The opposite ends of the first boss 63 are respectively connected to the first limiting platform 61 and the second limiting platform 62, and the opposite ends of the second boss 64 are also respectively connected to the first limiting platform 61 and the second limiting platform 62. In this way, the first boss 63, the first limiting platform 61, the second boss 64, and the second limiting platform 62 can be arranged around the assembly hole 601. The first boss 63, the first limiting platform 61, the second boss 64, and the second limiting platform 62 can also act as reinforcing ribs for the pressure plate 60, especially at the position where the assembly hole 601 is located, reducing the possibility of damage to the pressure plate 60 at the assembly hole 601.

[0098] In this embodiment, the connection between the support member 40 and the lever 50 is relatively reliable, which can reduce the damage caused by the lever 50 becoming loose or separating from the support member 40 due to tossing operations. Furthermore, the partition 20 is disposed between the support member 40 and the panel 10, which can also reduce the possibility of damage to the panel 10. Therefore, in this application, the structure of the switching device 100 is reasonably designed, reducing the possibility of damage to the lever 50 and the panel 10, thereby improving the reliability of the switching device 100.

[0099] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
