In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0031] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] When installing a wall switch in a wire box on a wall, it is usually necessary to first fix the PCB board with the micro switch 113 on the switch back seat 100, then insert the switch back seat 100 into the wire box, and fix the switch back seat 100 to the connection holes on both sides of the edge of the wall wire box by screws. When the screws are tightened, the switch back seat 100 will move away from the wire box opening, causing the two sides of the frame bracket 110 to be pulled and deformed by the switch back seat 100, thereby bearing a large torque, causing the switch PCB board 112 inside the switch to deform, and then causing the position of the micro switch 113 installed on the PCB board to change, causing the contact part of the switch button and the position of the micro switch 113 to be misaligned, so that the switch button cannot trigger the micro switch 113 correspondingly, and finally causing the switch button to fail.

[0033] In order to solve the above technical problems, the embodiments of the present application provide a wall switch installation structure and a wall switch.

[0034] Reference Figure 1 , Figure 2 As shown, an installation structure of a wall switch provided in an embodiment of the present application includes a switch back seat 100, which is arranged in a wire box installed on the wall. A switch PCB board 112 and an abutment plate 104 are provided on the switch back seat 100. The abutment plate 104 is arranged at the edge of the switch back seat 100 and extends to the outside of the opening of the wire box. The abutment plate 104 can abut against the wall and generate a supporting force acting on the switch PCB board 112; the switch PCB board 112 is provided with a micro switch 113 at a position close to the abutment plate 104.

[0035] It should be noted that, in the embodiment of the present application, the micro switch 113 is placed close to the abutment plate 104, so that the abutment plate 104 can reliably support the micro switch 113. Since the abutment plate 104 is located at the edge of the switch PCB board 112, the deformation is small, and the abutment plate 104 can be supported by the wall, so that the micro switch 113 and the button can be accurately aligned.

[0036] Among them, a sink 101 for mounting a switch PCB board 112 is provided on the switch rear seat 100 of the embodiment of the present application. The switch PCB board 112 is embedded in the sink 101. The sink 101 is provided with connecting parts 103 connected to the wire box on both sides of the first direction 102.

[0037] It should be noted that the plane formed by the intersection of the first direction 102 and the second direction 118 in the embodiment of the present application is parallel to the wall. The extension directions of the first direction 102 and the second direction 118 can be selected by those skilled in the art as needed, and are not particularly limited.

[0038] Exemplarily, the first direction 102 is perpendicular to the second direction 118. The first direction 102 may be a vertical direction, and the second direction 118 may be a horizontal direction.

[0039] It should be noted that the sink 101 is a recessed platform, and the switch PCB can be embedded in the sink 101. The plane where the sink 101 is located is parallel to the plane where the wall where the wire box is installed. In addition, it should be noted that the sink 101 is arranged at one end of the switch rear seat 100 close to the wall surface.

[0040] When the switch back seat 100 of the embodiment of the present application is inserted into the wire box, the abutment plate 104 extends outward and abuts against the edge of the wire box, and this part of the structure can abut against the wall. In a specific application, the connection part 103 fixes the switch back seat 100 through a connection piece such as a bolt, so that the left and right sides of the switch back seat 100 are deformed. The upper and lower sides abut against the wall through the abutment plate 104 to form an effective support for the switch PCB board 112.

[0041] It should be noted that the switch PCB board 112 is not connected to the left and right sides and the connecting part 103, that is, the left and right sides of the switch PCB board 112 can be separately set from the connecting part 103, so that the switch PCB board 112 is always clamped and fixed by the upper and lower abutment plates 104 to prevent deformation during assembly.

[0042] The embodiment of the present application provides a mounting structure of a wall switch, comprising a switch back seat 100, which is arranged in a wire box installed on the wall, and a switch PCB board 112 and an abutment plate 104 are arranged on the switch back seat 100, and the abutment plate 104 extends to the outside of the opening of the wire box, and the abutment plate 104 can contact and abut against the wall and generate a supporting force acting on the switch PCB board 112; the switch PCB board 112 is provided with a micro switch 113 at a position close to the abutment plate 104. The abutment plate 104 of the embodiment of the present application can abut against the wall through the part extending out of the opening, thereby achieving better support for the switch PCB board 112, effectively preventing the switch PCB board 112 from being deformed, ensuring that the micro switch 113 and the button can be accurately aligned, and effectively reducing the failure rate of the wall switch.

The buckle assembly can be arranged on both sides of the second direction, or on the edge of the abutment plate 104, to prevent the left and right sides of the switch bracket plate 107 from being connected to the switch rear seat 100. To a certain extent, the left and right sides of the switch bracket plate 107 can be prevented from being pulled and deformed during installation, which is conducive to preventing the micro switch 113 from being deformed.
