[0018] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0019] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0020] like Figure 1 As shown, a switch includes a switch body and a switch button 100. The switch body includes a base 200 and a housing 300 covering the base 200. The switch body is provided with a contact assembly. The switch button 100 is swayably connected to the upper end of the switch body 100 and cooperates with the contact assembly to allow the switch to be pressed.

[0021] like Figure 2As shown, the contact assembly includes two sets of pin assemblies fixed on the base 200 and two moving contact bridges 410 that cooperate with the two sets of pin assemblies respectively. Each set of pin assemblies includes a common pin 420 and a first side pin 430 and a second side pin 440 located on both sides of the common pin 420 respectively. The moving contact bridge 410 is supported in the middle on the upper end of the common pin 420 and has moving contacts 411 at both ends respectively. The first side pin 430 and the second side pin 440 are respectively provided with a first stationary contact 431 and a second stationary contact 441 for cooperating with the moving contacts 411. The switch button 100 cooperates with the moving contact bridge 410 to drive the moving contact bridge 410 to swing synchronously between the first side pin 430 and the second side pin 440, so that the two common pins 420 simultaneously contact the first side pin 430 or simultaneously contact the second side pin 440.

[0022] Furthermore, a light-emitting component 500 is fixed between the base 200 and the housing 300, such as... Figures 2-5 As shown, the light-emitting component includes a circuit board 510, a first indicator light 520 and a second indicator light 530 fixed on the circuit board 510. The circuit board 510 is fixed in the switch body. The housing 300 is provided with a light guide structure corresponding to the first indicator light 520 and the second indicator light 530. The switch button 100 is provided with a light-transmitting structure corresponding to the first indicator light 520 and the second indicator light 530, so that the indicator light of the first indicator light 520 and the second indicator light 530 can be displayed.

[0023] The first and second indicator lights are used to indicate the first and second switch states, respectively. In the first switch state, the two moving contact bridges are in synchronous contact with the two first side pins. In the second switch state, the two moving contact bridges are in synchronous contact with the two second side pins. Therefore, after the switch wiring in this embodiment is used, when the two moving contact bridges 410 are in synchronous contact with the two first side pins 430, the first indicator light 520 is on and the second indicator light 530 is off; when the two moving contact bridges 410 are in synchronous contact with the two second side pins 440, the second indicator light 530 is on and the first indicator light 520 is off. During use, the indicator lights are on in both switch states, making it easy for users to judge the switch state. Furthermore, the indicator lights remain on at night, helping users quickly locate the switch.

[0024] The circuit board 510 has a first contact and a second contact that are electrically connected to two common pins 420 respectively. A first unidirectional conducting electronic component 540 is provided on the first control line connecting the first contact, the first indicator light 520, and the second contact. A second unidirectional conducting electronic component 550 is provided on the second control line connecting the first contact, the second indicator light 530, and the second contact. The first and second unidirectional conducting electronic components 540 and 550 have opposite conduction directions. By reversing the power input directions of the first and second contacts, the first indicator light 520 and the second indicator light 530 are controlled to illuminate respectively. Specifically, when the first and second contacts are respectively positive and negative, the first indicator light 520 illuminates and the second indicator light 530 is off; when the first and second contacts are respectively negative and positive, the second indicator light 530 illuminates and the first indicator light 520 is off.

[0025] Specifically, circuit board 510 also includes a first resistor 560, a second resistor 570, a first indicator light 520, a second indicator light 530, a first unidirectional conducting electronic component 540, a second unidirectional conducting electronic component 550, and the first resistor 560 and second resistor 570, forming an integrated module with circuit board 510. The first contact, the second contact, the first indicator light 520, the first resistor 560, and the first unidirectional conducting electronic component 540 are connected in series to form a first control circuit for controlling the first indicator light 520. The first contact, the second contact, the second indicator light 530, the second resistor 570, and the second unidirectional conducting electronic component 550 are connected in series to form a second control circuit for controlling the second indicator light 530. To achieve the opposite power input directions of the first and second contacts, that is, in the two states of the control switch, the positive and negative terminals of the two common terminal pins 420 are connected in opposite directions, the positive and negative wiring of the two first side pins 430 of the two sets of pin assemblies is opposite to the positive and negative wiring of the two second side pins 440.

[0026] Furthermore, the first indicator light 520 and the second indicator light 530 are respectively set on both sides of the swing of the switch button 100, so that the user can easily judge the position of the two switch states of the switch button 100.

[0027] Specifically, the base 200 is provided with a partition 210, two sets of pin assemblies are respectively fixed on both sides of the partition 210, two sets of moving contact bridges 410 are also respectively located on both sides of the partition 210, and the circuit board 510 is fixed above the partition 210, such as... Figure 3 , Figure 4As shown, a swing assembly 700 is provided between the base 200 and the housing 300. The swing assembly 700 is connected between the switch button and the moving contact bridge 410. The swing assembly 700 has a clearance groove, and the circuit board 510 and the partition 210 are located in the clearance groove. As an alternative embodiment, a structure for fixing the circuit board 510 can also be provided on the inner wall of the housing 300. However, since it is fixed by the base 200, it is easier to assemble, especially for automated production assembly.

[0028] Furthermore, the common terminal pin 420 has an integrally formed upwardly extending indicator light pin 421 near the partition 210. The first and second contacts of the circuit board 510 correspond to the positions of the two indicator light pins 421, and the two indicator light pins 421 are electrically connected to the first and second contacts of the circuit board 510 through plugging and / or soldering. As an alternative embodiment, wires can also be used for electrical connection. However, the integrated indicator light pins 421 with the common terminal pin 420 facilitate assembly.

[0029] like Figure 6 As shown, the light guiding structure on the housing 300 includes a first through hole disposed on the upper sidewall of the housing 300 and a light guiding post 600 fixed within the first through hole. Specifically, as shown... Figure 7 As shown, the light guide column 600 has a cone-shaped light-inlet structure 610 at its lower end near the light-emitting component and a spherical concave light-emitting structure 620 at its upper end away from the light-emitting component, thus achieving efficient "light capture" and uniform "light emission".

[0030] like Figure 8 As shown, the switch button 100 includes a rocker arm 110 and a panel 120 fixed above the rocker arm 110. The rocker arm 110 has a hinge structure connected to the housing 300. Both the rocker arm 110 and the panel 120 are made of opaque material. The light-transmitting structure includes two second through holes 111 on the rocker arm 110, two third through holes 121 on the panel 120, and a filter 130 fixed between the rocker arm 110 and the panel 120. The two filters 130 corresponding to the first indicator light 520 and the second indicator light 530 are of different colors to achieve different color indication effects for the two indication functions. Furthermore, the two third through holes 121 are of different shapes to achieve different indication effects for different indication symbols for different indication functions.

[0031] As an alternative embodiment, the rocker 110 can also be made of a transparent material for light transmission. To achieve different color indication effects for two different indication functions, the rocker 110 can be made of a two-color light-transmitting material to replace the two different color filters 130, for example, through a two-color injection molding process or splicing assembly. Alternatively, indicator lights of different light-emitting colors can be used as the first indicator light 520 and the second indicator light 530, respectively.

[0032] like Figure 2 , Figure 8 As shown, the rocker arm 110 has a drive rod 112 at its bottom, and the housing 300 has a through hole for the drive rod 112 to extend into. Specifically, as... Figure 9 As shown, the swing assembly 700 of this embodiment includes a swing member 710 and two push rods 720. The swing member 710 includes two push rod sleeves 711 spaced apart and a linkage part 712 connecting the upper ends of the two push rod sleeves 711. The upper end of each push rod sleeve 711 is provided with a rotating part 7111 and the lower end is provided with an opening for the push rod 720 to extend into. The push rod 720 extends into the push rod sleeve 711 and a compression spring 730 is provided between the push rod 720 and the inner end of the push rod sleeve 711. The space between the two push rod sleeves 711 spaced apart forms a clearance groove for the circuit board 510 and the partition 210 to be installed. Figure 4 As shown, two sets of mating top rod sleeves 711 and top rods 720 are located on both sides of the partition plate 210 and the light-emitting component 500, respectively. The linkage part 712 is located above the light-emitting component 500. Under the action of the compression spring 730, the lower end of the top rod 720 maintains abutment with the moving contact bridge 410 and forms a rotatable engagement relationship with the rotating part 7111 and the inner wall of the housing 300. The linkage part 712 is inserted into the drive rod 112 that extends into the housing 300, so that the swing component 700 can be driven to swing between the base 200 and the housing 300 by the swing rocker 110.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
