[0017] In another embodiment of the present disclosure, the interior of the housing has a core-pulling injection channel;
[0018] The first port of the core-pulling injection channel is located on the outer side wall of the shell, and the second port of the core-pulling injection channel is located on the groove wall of the accommodating groove.
[0019] In yet another implementation of the present disclosure, the housing has a hinge seat on a side facing the panel;

[0028] The technical solutions provided by the embodiments of the present disclosure have the following beneficial effects:
[0029] When the switch provided by the embodiments of the present disclosure turns an electrical system on or off, the user toggles the lever assembly, causing it to swing relative to the housing, thereby causing the lever assembly to swing along with it. During the swinging of the on / off assembly, the switch can be turned on or off, thereby turning the electrical system on or off.
[0030] When the switch is turned on or off, arc light generated by the switch assembly is transmitted through the housing and toward the panel.

DETAILED DESCRIPTION
[0047] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.
[0048] The embodiment of the present disclosure provides a switch, Figure 1 For the exploded view of the switch, see Figure 1 The switch includes a panel 10, a housing 20, a switching assembly 30 and a lever assembly 40.
[0049] Figure 2 This is a cross-sectional view of the switch, combined with Figure 2 In this embodiment, the panel 10 is arranged on one side of the shell 20, the on-off assembly 30 is located in the shell 20 and can swing relative to the shell 20, the lever assembly 40 is pivotally connected to the shell 20, the lever assembly 40 is inserted into the inner through hole 210 to cover the inner through hole 210, the lever assembly 40 is in contact with the on-off assembly 30, and the lever assembly 40 is configured to swing the on-off assembly 30 to turn the switch on or off.
[0050] When the switch provided by the embodiment of the present disclosure turns the electrical system on and off, the user toggles the lever assembly 40, causing the lever assembly 40 to swing relative to the housing 20, thereby causing the lever assembly 40 to swing along with the on / off assembly 30. During the swinging process of the on / off assembly 30, the switch can be turned on or off, thereby turning the electrical system on and off.
[0051] When the switch is turned on or off, arc light generated by the switch assembly 30 is transmitted through the housing 20 and toward the panel 10. Because the lever assembly 40 is inserted into the internal through-hole 210, it can shield the internal through-hole 210, effectively reducing the gap between the housing 20 and the lever assembly 40. As a result, when arc light is transmitted through the gap between the housing 20 and the lever assembly 40, the lever assembly 40 can effectively block the arc light, preventing the arc light from flashing out of the switch.
[0052] In some examples, the switch assembly 30 includes a seesaw and a terminal block. Silver dots are located at each end of the seesaw, and the seesaw's swing axis is located between the two ends. This design creates a seesaw-type switch. The silver dots at each end of the seesaw serve as the moving contacts, while the copper sheet connected to the terminal block serves as the stationary contact.
[0053] In other examples, the switch assembly 30 includes a pendulum and a terminal block. One end of the pendulum has a silver dot, and the pendulum's swing axis is located at the other end. This design creates a pendulum-type switch. The silver dot at the end of the pendulum serves as the moving contact, while the copper plate connected to the terminal block serves as the stationary contact.
[0054] The arc light generated by the switch assembly 30 is first transmitted to the housing 20 and then to the panel 10. Therefore, in this embodiment, the two gaps are shielded to block the arc light.
[0055] Figure 3 This is a schematic diagram of the assembly between the lever assembly and the housing, combined with Figure 3 In this embodiment, the orthographic projection of the lever assembly 40 on the plane where the inner through hole 210 is located covers the inner through hole 210 .
[0056] In the above implementation, the positional relationship between the inner through hole 210 and the housing 20 is designed in this manner to ensure that the lever assembly 40 effectively shields the inner through hole 210. Furthermore, because the orthographic projection of the lever assembly 40 is guaranteed to cover the inner through hole 210, the lever assembly 40 can always shield the inner through hole 210 even when the lever assembly 40 swings.
[0057] Continue to see Figure 3 In this embodiment, the housing 20 has a receiving groove 220 on one side facing the panel 10 , the inner through hole 210 is located at the bottom of the receiving groove 220 , and the lever assembly 40 is received in the receiving groove 220 .
[0058] Since the inner through hole 210 is located at the bottom of the accommodating groove 220 , the inner through hole 210 can be effectively shielded by the groove wall of the accommodating groove 220 , thereby preventing the arc light from being directly emitted from the inner through hole 210 .
[0059] In this embodiment, the wall of the receiving groove 220 has a roughened layer.
[0060] In the above implementation, the groove wall of the accommodating groove 220 is designed to be a roughened layer, which can reflect the arc light irradiated on the groove wall of the accommodating groove 220 in the form of diffuse reflection, thereby reducing the brightness of the reflected arc light.
[0061] In this embodiment, the switch further includes a light shield (not shown). The light shield is located in the receiving groove 220 and is sleeved on the outside of the lever assembly 40 so that the light shield covers the inner through hole 210 .
[0062] For example, the light shield is a conical structure, with the smaller end of the light shield connected to the lever assembly 40 and the larger end of the light shield connected to the bottom of the receiving groove 220. This design can prevent the light shield from affecting the swing of the lever assembly 40, while ensuring that the light shield fully blocks the inner through hole 210.
[0063] For example, the sunshade is made of a flexible material. Such a design allows the sunshade to deform adaptively with the swing of the lever assembly 40, thereby further ensuring that the sunshade does not affect the swing of the lever assembly 40.
[0064] Figure 4 The cross-sectional view of the shell, combined with Figure 4 In this embodiment, the interior of the shell 20 has a core-pulling injection channel 230, the first port of the core-pulling injection channel 230 is located on the outer wall of the shell 20, and the second port of the core-pulling injection channel 230 is located on the groove wall of the accommodating groove 220.
[0065] In the above implementation, the core-pulling injection molding channel 230 is used to accommodate the core-pulling during the injection molding process of the shell 20. Since the core-pulling injection molding channel 230 is located inside the shell 20, it will not cause the shell 20 to be hollowed out, and can ensure that the shell 20 is an integral structure, which is conducive to shielding the on-off component 30 accommodated inside the shell 20.
[0066] It is worth noting that the positions of the first port and the second port of the core-pulling injection molding channel 230 can be adjusted according to actual needs, and it is only necessary to ensure that the final core-pulling injection molding channel 230 is located inside the shell 20.
[0067] Exemplarily, the housing 20 has a hinge seat 240 on one side facing the panel 10 . The hinge seat 240 is located in the accommodating groove 220 . The hinge seat 240 is pivotally connected to the lever assembly 40 . The pivot socket of the hinge seat 240 is opposite to the second port of the core-pulling injection channel 230 .
[0068] In the above implementation, the hinge base 240 serves as a mounting base for the lever assembly 40. Since the hinge base 240 needs to accommodate the rotating shaft of the lever assembly 40, the hinge base 240 has a pivot socket. The second end of the core-pulling injection channel 230 is aligned with the pivot socket of the hinge base 240. This allows the core puller to extend into the pivot socket of the hinge base 240 through the second end of the core-pulling injection channel 230 during the injection molding process. This increases the core puller's range of motion and facilitates the injection molding process.
[0069] In this embodiment, the hinge seat 240 has a first guide bevel 241 on the side facing the lever assembly 40, and the first guide bevel 241 is close to the notch of the accommodating groove 220. The end of the pivot axis of the lever assembly 40 has a second guide bevel 460, and the second guide bevel 460 is used to slide in contact with the first guide bevel 241.
[0070] During the process of pivoting the lever assembly 40 and the housing 20, the first guide bevel 241 and the second guide bevel 460 slide into contact. With the mutual cooperation of the first guide bevel 241 and the second guide bevel 460, the pivot axis of the lever assembly 40 is guided into the pivot socket of the hinge seat 240, thereby realizing the pivotal assembly between the lever assembly 40 and the housing 20.
[0071] Through the above-mentioned contents, it is possible to effectively block arc light from flashing out from the gap between the lever assembly 40 and the housing 20. The following will continue to describe the relevant contents of blocking arc light from flashing out from the gap between the lever assembly 40 and the panel 10.
[0072] Figure 5 This is the assembly diagram between the lever assembly and the panel, combined with Figure 5 In this embodiment, the panel 10 has an outer through hole 120 , and the lever assembly 40 is inserted into the outer through hole 120 to cover the outer through hole 120 .
[0073] Since the lever assembly 40 is inserted into the outer through hole 120, the lever assembly 40 can shield the outer through hole 120, effectively reducing the gap between the panel 10 and the lever assembly 40. In this way, the arc light at the outer through hole 120 can be effectively shielded, preventing the arc light from flashing out of the switch.
[0074] In this embodiment, the orthographic projection of the lever assembly 40 on the plane where the outer through hole 120 is located covers the outer through hole 120 .
[0075] In the above implementation, the positional relationship between the external through hole 120 and the lever assembly 40 is designed in this manner, thereby ensuring that the lever assembly 40 effectively shields the external through hole 120. Furthermore, since the orthographic projection of the lever assembly 40 covers the external through hole 120, the lever assembly 40 can always shield the external through hole 120 even when the lever assembly 40 swings.
[0076] Figure 6 This is a schematic diagram of the panel structure, combined with Figure 6 In this embodiment, the panel 10 has an outer recess 170 on a side facing away from the housing 20 , and the outer through hole 120 is located in the outer recess 170 .
[0077] In the above implementation, setting the external through hole 120 in the outer recess 170 can effectively reduce the length of the external through hole 120, that is, the wall thickness of the panel 10 corresponding to the inner edge of the external through hole 120, thereby reducing the accumulation of dust at the external through hole 120.
