[0032] A wall switch is an electrical switch installed on a wall to connect and disconnect circuits, controlling lighting. Currently, existing wall switches typically include a panel, panel frame, mounting bracket, switch button, moving contact bridge, stationary contact, and terminal blocks. The mounting bracket is fixed to the wall, the panel frame is fixed to the outside of the mounting bracket, and the panel is hinged to the panel frame. The switch button, moving contact bridge, stationary contact, and terminal blocks are mounted on the mounting bracket. Pressing the panel activates the switch button, switching the on / off state.

[0033] However, the existing wall switch panel frames and mounting brackets are prone to deformation and misalignment during assembly, leading to switch malfunction or a poor feel. Additionally, uneven wall surfaces can also cause switch malfunction or a poor feel.

[0034] This application provides a wall switch, such as... Figure 1 , Figure 2 As shown: It includes panel buttons 1, panel frame 2, mounting bracket 3, switch buttons 4, and rear seat assembly 5.

[0035] Among them, mounting bracket 3 is the fixing part of the wall switch, which is usually fixed to the wall by screws or other means, providing stable support for the entire switch. Specifically, for example... Figure 3 As shown, the system includes a base plate and a mounting frame 32 connected to the outer periphery of the base plate. The mounting frame 32 has mounting holes 321 on both sides for fixing to a wall with screws, specifically to a switch box inside the wall. The panel frame 2 serves as the external structure of the switch, connecting to the mounting bracket 3 and supporting the switch panel buttons 1. It also serves as a decorative element for the wall switch, concealing the mounting structure of the mounting bracket 3. The panel buttons 1 are hinged within the panel frame 2, and their number can be set as needed, such as single-on, double-on, or more. The figure shows a single-on structure. Switch buttons 4 are hinged within the mounting bracket 3, corresponding to the number of panel buttons 1 and engaging with each one individually. The rear seat assembly 5 is connected to the rear side of the base plate and contains a conductive structure, specifically including a moving contact bridge, a stationary contact, and terminals. It engages with the switch buttons 4 through switch drive through holes 31 on the base plate to transmit the switch's action.

[0036] To address the problems in related technologies, this application provides a first snap-fit ​​connection structure between the panel frame 2 and the mounting bracket 3, specifically, as follows: Figure 3 As shown, the mounting frame 32 is provided with at least two first snap-fit ​​grooves 322 extending along the depth direction, and a first snap-fit ​​block 323 is provided in the first snap-fit ​​groove 322; as Figure 4 , Figure 5 As shown, the panel frame 2 is provided with a first rack 22 corresponding to the position of the first snap-fit ​​groove 322, and the first rack 22 is provided with at least two first toothed grooves 221 extending along the depth direction Z; wherein, as Figure 7As shown, the first rack 22 is inserted into the first snap-fit ​​groove 322, and the first snap-fit ​​block 323 engages with one of the at least two first toothed grooves 221. In this application, the depth direction Z refers to the direction perpendicular to the wall surface. During installation, the worker first fixes the mounting bracket 3 to the wall, and then aligns the first rack 22 of the panel frame 2 with the first snap-fit ​​groove 322 and inserts it. Fixing is achieved by the first snap-fit ​​block 323 engaging with the selected first toothed groove 221. Multiple first toothed grooves 221 are allowed to engage at different depths, so that the relative height positions of the panel frame 2 and the mounting bracket 3 at different engagement points can be different, in order to compensate for the deformation of the mounting bracket 3 or the unevenness of the wall surface. This provides height adjustability during assembly, reduces the skewing problem caused by the deformation of the mounting bracket or the unevenness of the wall surface, thereby improving the overall structural stability and operational reliability of the switch. At the same time, it simplifies the installation process, eliminates the need for precise alignment, and reduces the risk of failure caused by assembly errors.

[0037] Optionally, in some embodiments, the mounting frame 32 is square, and the first snap-fit ​​slots 322 are provided with four slots distributed near the four corners of the mounting frame 32. The mounting frame 32 adopts a rectangular structure, with the four first snap-fit ​​slots 322 located at the four corners of the frame. The four snap-fit ​​slots distributed at the four corners provide balanced support and prevent the panel frame from tilting due to local stress, which is especially suitable for large-size switch panels. At the same time, the multi-corner design simplifies the alignment process, and even if the wall surface is slightly uneven, the panel can be kept level by adjusting the engagement depth of different snap-fit ​​slots. In the assembly process, the worker first fixes the mounting bracket 3, and then inserts the first toothed racks 22 of the panel frame 2 one by one. The optimal engagement toothed groove in each snap-fit ​​slot is selected according to the flatness of the wall surface. For example, if a corner of the wall is concave, a deeper toothed groove is selected at that corner to compensate for the height difference.

[0038] Optionally, in some embodiments, the panel frame 2 includes a connecting frame 21, the shape of which is adapted to the shape of the mounting frame 32 so that it covers the top and outer periphery of the mounting frame 32, and the first toothed rack 22 is disposed on the connecting frame 21. The connecting frame 21 covers the upper surface and sides of the mounting frame 32, forming a wrap-around structure, and the first toothed rack 22 is directly fixed to the inner sidewall of the connecting frame 21; after assembly, the connecting frame 21 hides the edge of the mounting frame 32, improving the neatness of the appearance, enhancing the aesthetics and protective performance of the wall switch, effectively concealing the internal structure, and preventing dust and foreign objects from entering the switch. During the manufacturing process, the connecting frame 21 is integrally injection molded, and the first toothed rack 22 is directly molded as part of the frame, ensuring structural strength and dimensional accuracy. As an alternative embodiment, those skilled in the art can also design the connecting frame 21 to only partially cover the mounting frame 32, for example, only covering the top without wrapping the sides, to simplify the assembly.

[0039] Alternatively, in some embodiments, such as Figure 4 As shown, a crossbeam 23 is provided inside the connecting frame 21, and both ends of the crossbeam 23 are fixedly connected to the connecting frame 21. The crossbeam 23 is arranged horizontally inside the connecting frame 21, and its two ends are fixed to the frame to form an internal support skeleton; after assembly, the crossbeam 23 shares the load of the panel and prevents the frame from deforming. Specifically, the two ends of the crossbeam 23 are integrally injection molded to form a connection with the connecting frame 21, reducing assembly steps. The crossbeam 23 connects the two ends of the frame 21 to form a closed frame, effectively distributing the operating force and reducing the bending deformation of the panel frame 2 during repeated opening and closing actions, ensuring consistent and reliable switch feel.

[0040] Optionally, in some embodiments, the crossbeam 23 is provided with at least two hinged mounting portions 231, and the at least two hinged mounting portions 231 are spaced apart along the transverse X direction. The hinged mounting portions 231 are protrusions or grooves distributed on the surface of the crossbeam 23 for mounting panel buttons 1. The number of hinged mounting portions 231 can be large to accommodate the installation of different numbers of panel buttons 1.

[0041] Alternatively, in some embodiments, such as Figure 6 As shown, a second snap-fit ​​connection structure is provided between the crossbeam 23 and the base plate of the mounting bracket 3. Specifically, as shown... Figure 4 As shown, the bottom of the crossbeam 23 is provided with a snap-fit ​​connecting seat 24, and the snap-fit ​​connecting seat 24 is provided with a second snap-fit ​​groove 241 extending along the depth direction, and a second snap-fit ​​block 242 is provided in the second snap-fit ​​groove 241; as Figure 3 As shown, the base plate of the mounting bracket 3 is provided with a second rack 33 corresponding to the position of the second snap-fit ​​groove 241, and the second rack 33 is provided with at least two second toothed grooves 331 extending along the depth direction; wherein, as Figure 8 , Figure 9As shown, the second rack 33 is inserted into the second snap-fit ​​groove 241, and the second snap-fit ​​block 242 engages with one of the at least two second racks 331. The snap-fit ​​connector 24 is fixed to the lower surface of the crossbeam 23. The engagement method between the second snap-fit ​​groove 241 and the second rack 33 is similar to that of the first snap-fit ​​structure. During assembly, the second rack 33 is inserted into the second snap-fit ​​groove 241, and the second snap-fit ​​block 242 engages with the selected second rack 331. This structure provides additional connection points, enhances the stability between the crossbeam and the base plate, avoids the crossbeam 23 from arching, and prevents the switch surface of the multi-opening structure from arching, thus strengthening the overall structural integrity and deformation resistance of the wall switch. The multi-stage engagement of the second snap-fit ​​groove 241 and the second rack 33 allows for height adjustment to compensate for unevenness of the base plate, reducing switch malfunctions caused by installation errors. At the same time, this design shares the load of the first snap-fit ​​structure, improving the reliability of the installation structure. During the assembly process, the worker first fixes the mounting bracket 3 base plate to the wall, then presses down the panel frame 2, and the second rack 33 automatically inserts into the second snap-fit ​​slot 241. By selecting different second rack slots 331 to mesh, the worker adapts to the height difference of the base plate.

[0042] Optionally, in some embodiments, the two sides of the snap-fit ​​connector 24 protrude relative to the two sides of the crossbeam 23, and each of the protruding portions is provided with a second snap-fit ​​groove 241. The two protrusions of the snap-fit ​​connector 24 extend beyond the width of the crossbeam 23, and each protruding portion integrates a second snap-fit ​​groove 241; during assembly, this increases the number of connection points and improves the meshing strength. As an alternative embodiment, those skilled in the art may also provide a protrusion on only one side, but the double-sided design is more balanced. This solution is beneficial for enhancing the robustness and torsional resistance of the connection structure: the two protrusions on both sides are provided with second snap-fit ​​grooves 241, forming symmetrical support, effectively resisting lateral forces or torsional loads, and preventing the switch panel from loosening. Optionally, in some embodiments, the snap-fit ​​connector 24 is provided with at least two snap-fit ​​connectors 24 spaced apart in the lateral X direction. The lateral spacing of at least two snap-fit ​​connectors 24 disperses the operating force of the panel, which is particularly suitable for wide-range switches and reduces the risk of local deformation; at the same time, it allows each connection point to be independently adjusted in height to adapt to uneven walls or bases. Specifically, the snap-fit ​​connector 24 and the crossbeam 23 are integrated into a single design, reducing the number of parts. This optimization reduces production costs and improves assembly efficiency.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
