[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] The present invention provides the following technical solutions:

[0023] As attached Figure 1-6As shown, the present invention discloses a wall switch with a double-swing-piece springboard 5, comprising a switch panel 1, a panel bracket 2 and a switch back seat 3, wherein the switch panel 1 is arranged on the panel bracket 2, the panel bracket 2 is arranged on the switch back seat 3, a mounting cavity 4 is formed in the switch back seat 3, a double-swing-piece springboard 5 and a power-on component 6 are arranged in the mounting cavity 4, at least one moving contact 7 is arranged on the double-swing-piece springboard 5, the power-on component 6 is connected to the moving contact 7 on the double-swing-piece springboard 5, a swinging member 8 is arranged on the switch back seat 3, one end of the swinging member 8 extends into the mounting cavity 4 and is connected to the double-swing-piece springboard 5, and the swinging member 8 drives the double-swing-piece springboard 5 and the power-on component 6 to perform circuit on-off control. Specifically, in the present design, by arranging a double-swing-plate springboard 5 in the installation cavity 4, at least one moving contact 7 is arranged on the two springboard swinging parts 10 on the double-swing-plate springboard 5, so that the power-carrying components 6 in different installation positions can be adapted, that is, there is no need to fix the main or auxiliary position in the switch rear seat 3, so that the installation is more flexible and convenient. At the same time, the double-swing-piece springboard 5 is designed to contact the swinging member 8, and swings under the drive of the swinging member 8. During the swinging process of the springboard body 9, it can drive the springboard swinging member 10 to swing so that the moving contacts 7 on the springboard swinging member 10 can contact or disconnect with the static contacts on the power-carrying component 6, thereby achieving the purpose of controlling the on-off of the circuit; compared with the traditional springboard switch, the present design achieves circuit on-off control through the swinging of the springboard swinging member 10, which can improve the pressing feel and improve the user experience; and compared with the traditional swing-piece switch, the present design uses line contact between the springboard body 9 and the power-carrying component 6 to increase the contact area between the two, reduce temperature rise, and extend the service life of the double-swing-piece springboard 5.

[0024] Further, the double swing plate springboard 5 has a springboard body 9 and a springboard swinging part 10, the springboard swinging part 10 includes a first swinging part 11 and a second swinging part 12, the first swinging part 11 and the second swinging part 12 are respectively arranged on different sides of the two ends of the springboard body 9, the power-on component 6 is arranged on both sides of the double swing plate springboard 5 corresponding to the positions of the first swinging part 11 and the second swinging part 12, the moving contact 7 is arranged on the first swinging part 11 and / or the second swinging part 12, and the swinging member 8 is connected to the springboard body 9. Specifically, in this embodiment, the design of the double swing plate springboard 5 allows the moving contact 7 to be flexibly arranged on the first swinging part 11 and / or the second swinging part 12 to adapt to the power-on components 6 at different positions, thereby increasing the flexibility of installation. At the same time, the swinging member 8 is connected to the springboard body 9, and the swinging of the swinging member 8 can drive the springboard body 9 and the springboard swinging part 10 to swing, thereby realizing the on-off control of the circuit. This design not only improves the pressing feel, but also increases the contact area and reduces the temperature rise through the line contact between the springboard body 9 and the power-on component 6, thereby extending the service life of the double-swing-piece springboard 5.

[0025] Furthermore, the power-on component 6 includes a conductive sheet 13 and a terminal 14, a slot 15 corresponding to the terminal 14 is arranged in the cavity wall of the installation cavity 4, the terminal 14 is fixed in the slot 15, the conductive sheet 13 is connected to the terminal 14, a plurality of the terminal 14 are arranged, a springboard mounting portion 16 is formed between the terminal 14, the double-swing-plate springboard 5 is arranged in the springboard mounting portion 16, a springboard limiting structure 17 is arranged in the springboard mounting portion 16, and the springboard limiting structure 17 limits the position of the double-swing-plate springboard 5 in the springboard mounting portion 16. Specifically, in this embodiment, the terminals 14 fixed in the slots 15 on both sides of the double swing plate springboard 5 are respectively the main terminals 141, the auxiliary terminals 142 and the dual control terminals 143, the main terminals 141 and the auxiliary terminals 142 are arranged on the same side, and because the double swing plate springboard 5 is arranged, the first swing part 11 and the second swing part 12 on the double swing plate springboard 5 can be matched with the corresponding terminals 14, and both can be welded with the moving contact 7 on the first swing part 11 and the second swing part 12, and the moving contact 7 can be matched with the static contact on the conductive sheet 13 on the corresponding terminal 14, so there is no need to distinguish and limit the positions of the main terminals 141 and the auxiliary terminals 142, thereby greatly improving the flexibility and convenience of the switch installation. In addition, by setting the springboard limiting structure 17, the position of the double swing plate springboard 5 in the springboard installation part 16 can be ensured to be stable, preventing it from being offset or shaking during operation, and ensuring the accuracy and stability of the circuit on and off.

[0026] Further, the springboard limiting structure 17 is arranged at the two ends of the double swing plate springboard 5, and the springboard limiting structure 17 is two limiting blocks arranged at a distance, and a limiting groove 18 is formed between the limiting blocks, and the two ends of the double swing plate springboard 5 extend into the corresponding limiting groove 18 and are connected to the springboard limiting structure 17. Specifically, in this embodiment, the springboard limiting structure 17 composed of the limiting blocks can limit the two ends of the double swing plate springboard 5 in the limiting groove 18, so that the position of the double swing plate springboard 5 in the springboard mounting portion 16 is fixed, and the double swing plate springboard 5 is prevented from shaking in the mounting cavity 4, which affects the stability of the circuit on-off control. At the same time, a certain gap is formed between the limiting blocks and the two ends of the double swing plate springboard 5, so that the double swing plate springboard 5 will not be subjected to excessive resistance during the swinging process, and the flexibility of the swinging of the springboard is guaranteed.

[0027] Furthermore, the first springboard swinging part 10 and the second springboard swinging part 10 both have a supporting part 19, an inclined connecting part 20 and a contact mounting part 21, the inclined connecting part 20 is arranged between the supporting part 19 and the contact mounting part 21, and the end of the supporting part 19 away from the inclined mounting part is connected to the springboard body 9.

[0028] Furthermore, the angle formed between the inclined connection part 20 and the support part 19 and the contact mounting part 21 is 135°±4°. Such a structural setting can make the contact between the springboard body 9 and the power-carrying component 6 more stable during the swinging process of the double-swing-piece springboard 5, reduce the contact resistance, and improve the stability of the switch. At the same time, such a structural setting can also make the contact between the moving contact 7 and the static contact end 22 smoother during the swinging process of the springboard swinging part 10, reduce wear, and extend the service life of the switch. In addition, under this structure, the swinging angle of the moving contact 7 during the swinging process is moderate, so that the static contact does not need to be placed far away from the moving contact 7, thereby reducing the required space and reducing the volume of the switch box.

[0029] Further, swing limit ends 23 are provided on both sides of the springboard body 9, the swing limit ends 23 are bent toward the upper part of the springboard body 9, and a rounded structure 24 is provided between the swing limit ends 23 and the springboard body 9, and the angle of the central angle of the rounded structure 24 is 107°±3°. Specifically, in the present embodiment, swing limit ends 23 are provided on both sides of the springboard body 9, which are bent toward the upper part of the springboard body 9, and a rounded structure 24 is formed between the springboard body 9. This design accurately limits the swing position of the swing member 8 on the springboard body 9, ensuring the stability and reliability of the switch. During the swing of the swing member 8 on the springboard, due to the provision of the rounded structure 24, it is possible to avoid the swing member 8 from being directly contacted with the swing limit ends 23 when the switch is pressed, causing wear of the swing member 8, and can improve the feel of pressing the switch, ensuring the smoothness of the switch pressing.

[0030] In this embodiment, the double swing plate springboard 5 is used in a single-opening wall switch, while in other embodiments, the double swing plate springboard can also be used in a two-opening switch, a three-opening switch, and a four-opening switch, and can better reflect the installation flexibility of the double swing plate springboard. In the design of a multi-opening switch, the double swing plate springboard 5 can be adapted to different contact layouts and wiring requirements through simple adjustment. Since the double swing plate springboard 5 adopts a line contact method, it can increase the contact area and reduce the contact resistance, thereby reducing the temperature rise and improving the stability and service life of the switch.
