The first mounting position can install either the light guide or the limiting member. When the light guide is installed in the first mounting position, pressing the cover plate at the position corresponding to and near the light guide causes the driving protrusion on the cover plate near the light guide to drive the corresponding micro switch. When the limiting member is installed in the first mounting position, pressing the cover plate at the position corresponding to and near the limiting member causes the limiting member to limit the cover plate so that the driving protrusion near the limiting member cannot drive the corresponding micro switch.

[0015] In one possible implementation, the wall switch includes a receiving slot for accommodating excess light guides and / or limiting elements.

[0016] In one possible implementation, the first mounting position is located on the side of the cover plate facing the first pressure plate, the first mounting position includes a limiting frame, the light guide includes a fixing body fixedly mounted to the limiting frame, the limiting member includes a mounting body fixedly mounted to the limiting frame, and the thickness of the mounting body of the limiting member is greater than the thickness of the fixing body of the light guide.

[0017] In one possible implementation, the light guide further includes a first light-inlet portion and a first light-outlet portion connected to both ends of the fixed body along its length. The first light-inlet portion corresponds to a first light-guiding through-hole on the first pressure plate, and the first light-outlet portion corresponds to a display window. The first light-guiding through-hole is offset from the display window, and the first light-inlet portion and the first light-outlet portion are also offset.

[0018] In one possible implementation, the limiting frame has a first notch, the display window is located outside the limiting frame and on one side of the first notch, and the fixing body includes a first extension extending out of the first notch, with the first light-emitting part located in the first extension.

[0019] In one possible implementation, the light guide is a light-transmitting light guide; the limiting member is an opaque limiting member.

[0020] In one possible implementation, the first mounting position is located on the side of the cover plate facing the first pressure plate, or the first mounting position is located on the side of the first pressure plate facing the cover plate.

[0021] In one possible implementation, the wall switch is further provided with a drive element, and the drive protrusion of the cover plate indirectly drives the micro switch through the drive element.

[0022] In one possible implementation, the first pressure plate includes at least two locking shafts, and the cover plate facing the first pressure plate is provided with two first buckles, which are rotatably engaged with the two locking shafts; the first pressure plate includes at least two locking holes or slots, the locking shafts are located in the locking holes, the first buckles include two clamping arms, a retaining ring is formed between the two clamping arms, the retaining ring is engaged with the locking shaft, and the two clamping arms clamp the locking shaft.

[0023] In one possible implementation, at least one elastic element is provided on the side of the first pressure plate facing the cover plate. The first pressure plate includes at least one elastic through hole. The at least one elastic element and the at least one elastic through hole correspond one-to-one along the thickness direction of the wall switch. One end of the elastic element is integrally injection molded and connected to the first pressure plate, and the other end is movably disposed and extends toward the cover plate. The elastic element can be inserted into the elastic through hole when subjected to force. The elastic element generates elastic force through plastic deformation to drive the cover plate to reset.

[0024] In one possible implementation, the first pressure plate has at least two opposing sides, each including at least one first inner buckle protrusion. The mounting box includes at least one first inner buckle groove or first inner buckle hole corresponding to the position of the at least one first inner buckle protrusion.

The side of the mounting box with the first inner buckle groove or first inner buckle hole is provided with at least one third limiting protrusion. The at least one third limiting protrusion abuts against the at least one first limiting notch after limiting, thereby limiting the movement of the first pressure plate and the mounting box in the thickness direction of the wall switch.

[0025] In one possible implementation, the circuit board is installed inside a mounting box, and the second pressure plate is snap-fitted to the mounting box, limiting the movement of the circuit board in the thickness direction of the wall switch; the second pressure plate includes at least one extension arm extending toward the mounting box, the extension arm being provided with a second snap-fit ​​protrusion, the mounting box including at least one extension arm through hole, the mounting box being provided with a second snap-fit ​​hole or a second snap-fit ​​groove at a corresponding position of the extension arm through hole, at least one of the extension arms extending into at least one of the extension arm through holes, and at least one second snap-fit ​​protrusion being snap-fitted to at least one second snap-fit ​​hole or second snap-fit ​​groove.

[0027] In one possible implementation, the wall switch includes at least one decorative panel, and the cover plate has a panel mounting groove on the side facing away from the first pressure plate. The decorative panel is fixed to the panel mounting groove by a snap fastener or glue. The decorative panel has at least one second display window, and the at least one second display window corresponds to the display window on the cover plate in the thickness direction of the wall switch.

[0028] Compared to existing technologies, this application provides a wall switch with a first mounting position capable of installing either a light guide or a limiting member. When the light guide is installed at the first mounting position, pressing the cover plate at the corresponding position and vicinity of the light guide causes a driving protrusion on the cover plate adjacent to the light guide to drive a corresponding micro switch. When the limiting member is installed at the first mounting position, pressing the cover plate at the corresponding position and vicinity of the limiting member causes the limiting member to restrict the cover plate, preventing the driving protrusion adjacent to the limiting member from driving the corresponding micro switch. Thus, by installing either a light guide or a limiting member at the first mounting position, the pressable position of the cover plate can be changed, satisfying various user needs regarding the cover plate's operating position. For example, it can satisfy the user's need to press the lower end when the upper end is fixed, or press the upper end when the lower end is fixed, or even allow pressing from both the upper and lower ends.

[0029] In addition, the thickness of the limiting member is greater than the thickness of the light guide member. When the cover plate is pressed at the corresponding position and near the limiting member, the larger thickness of the limiting member abuts against the first pressure plate or the cover plate, which can reduce the rotation angle of the cover plate, prevent the cover plate from continuing to rotate, and prevent the cover plate from driving the micro switch at its corresponding position.

[0030] In addition, the wall switch includes a receiving slot for accommodating excess light guides and / or limiting members. When not in use, the light guides and limiting members can be placed in the receiving slot for easy access and placement.

[0031] In addition, the light guide further includes a first light-inlet portion and a first light-outlet portion connected to both ends of the fixed body along its length. The first light-inlet portion is located on the side of the fixed body facing the light-emitting element and extends towards the light-emitting element, and the first light-outlet portion is located on the side of the fixed body facing the display window and extends towards the display window. The limiting member further includes an operating portion perpendicularly connected to the mounting body. The mounting body is installed within the limiting frame, and the operating portion faces the first pressure plate. The first light-inlet portion and the first light-outlet portion are used to guide light from the light-emitting element to the display window, thereby increasing the light guiding intensity.

[0032] In addition, a first reflective slope is provided at the connection position between the first light-inlet part and the fixed body. The first reflective slope is used to reflect the light entering the first light-inlet part to the first light-outlet part.

[0033] In addition, the wall switch also includes a second pressure plate stacked between the first pressure plate and the circuit board. The second pressure plate is fixedly installed with the mounting box, limiting the movement of the circuit board and enhancing the stability of the circuit board after installation.

[0059] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0060] The pressing position of existing wall switches cannot be adjusted as needed, and the pressing area is fixed, which cannot meet the diverse needs of consumers.

[0061] like Figures 1-9 As shown, this application provides a wall switch including at least one cover plate 1, a first pressure plate 2, a second pressure plate 3, a circuit board 4, and a mounting box 5. At least one cover plate 1 is disposed on the first pressure plate 2, and the first pressure plate 2, the second pressure plate 3, the circuit board 4, and the mounting box 5 are stacked. The cover plate 1 is rotatably connected to the first pressure plate 2, the first pressure plate 2 is fixedly connected to the mounting box 5, the circuit board 4 is installed inside the mounting box 5, and the second pressure plate 3 is fixedly connected to the mounting box 5, limiting the movement of the circuit board 4 in the thickness direction of the wall switch to enhance the stability of the circuit board 4 after installation. Wherein, as... Figure 1 and Figure 4 As shown in the figure, this application illustrates an embodiment in which three side-by-side cover plates 1 are mounted on a first pressure plate 2.

[0062] Preferably, in one embodiment, the wall switch may not have the second pressure plate 3, and the first pressure plate 2 is fixedly installed with the mounting box 5 and then limits the circuit board 4, or the circuit board 4 is fixedly installed with the mounting box 5 and then limits its position.

[0063] like Figures 3-4 , Figures 7-8As shown, the circuit board 4 includes at least one micro switch 41 electrically connected. The first pressure plate 2 includes at least one first drive through hole 21, and the second pressure plate 3 includes at least one second drive through hole 31. At least one of the cover plates 1 is provided with at least one drive protrusion 11 on the side facing the first pressure plate 2. At least one micro switch 41, at least one first drive through hole 21, at least one second drive through hole 31 and at least one drive protrusion 11 correspond one-to-one in the thickness direction of the wall switch. Pressing the cover plate 1 causes at least one drive protrusion 11 to pass through at least one first drive through hole 21 and at least one second drive through hole 31 in sequence and act on at least one micro switch 41, driving the micro switch 41 to open or close.

[0064] Preferred, such as Figures 3-4 , Figures 7-8 As shown, the circuit board 4 is electrically connected to at least one light-emitting element 42, and at least one light-emitting element 42 is close to at least one micro switch 41 in a one-to-one correspondence. The cover plate 1 includes at least one display window 12, and the display window 12 is adjacent to the driving protrusion 11. The first pressure plate 2 is provided with at least one first light-guiding through hole 22, and the second pressure plate 3 is provided with at least one second light-guiding through hole 32.

[0065] like Figure 1 As shown, the improvement of this application is that the wall switch further includes at least one light guide 6 and at least one limiting member 7 that can be interchanged with each other, and the wall switch is provided with a first mounting position 13 adjacent to the display window 12, the first mounting position 13 can install any one of at least one light guide 6 and at least one limiting member 7.

[0066] When the light guide 6 is installed at the first mounting position 13, pressing the cover plate 1 at the corresponding position and near the light guide 6 will cause the driving protrusion 11 on the cover plate 1 adjacent to the light guide 6 to drive the corresponding micro switch 41.

[0067] When the limiting member 7 is installed at the first mounting position 13, the cover plate 1 is pressed at the corresponding position and the vicinity of the limiting member 7. The limiting member 7 limits the cover plate 1 so that the driving protrusion 11 adjacent to the limiting member 7 cannot drive the corresponding micro switch 41.

[0068] The light guide 6 or the limiting member 7 is located between the light-emitting element 42 and its corresponding display window 12 in the thickness direction of the wall switch. The light-emitting element 42 may be, but is not limited to, an LED light, and the light guide 6 may be made of a light-transmitting material, such as light-transmitting silicone, light-transmitting glass, or light-transmitting plastic.

[0069] Preferably, the first mounting position 13 is located on the side of the cover plate 1 facing the first pressure plate 2, or the first mounting position 13 is located on the side of the first pressure plate 2 facing the cover plate 1.

[0070] like Figure 4 As shown, in this embodiment, the cover plate 1 has at least one first mounting position 13 on the side facing the first pressure plate 2, the display window 12 is located at the first mounting position 13, and at least one driving protrusion 11 corresponds to and is close to the at least one first mounting position 13.

[0071] By installing a light guide 6 or a limiting member 7 at the first mounting position 13, the pressable position of the cover plate 1 can be changed, satisfying various user needs for the operating position of the cover plate 1. In practical applications, it can meet the needs of consumers to press the lower end while fixing the upper end, or press the upper end while fixing the lower end, or even press both the upper and lower ends.

[0072] At least one first mounting position 13, at least one first light guide hole 22, at least one second light guide hole 32, and at least one light-emitting element 42 correspond one-to-one in the thickness direction of the wall switch. Furthermore, the limiting member 7 is made of opaque material and is an opaque limiting member. When installed in the first mounting position 13, it blocks the first light guide hole 22, preventing light from the light-emitting element 42 from passing through, thus preventing the display window 12 from displaying and indicating that this area cannot be pressed. The light guide member 6 is a transparent light guide member. When installed in the first mounting position 13, it guides the light from the light-emitting element 42 to the display window 12, indicating that this area can be pressed. The light-emitting element 42 can use different colors to indicate the state of the wall switch.

[0073] The upper surface is the side of the first pressure plate 2 facing the cover plate 1.

[0074] like Figure 4 As shown in this embodiment, the cover plate 1 facing the first pressure plate 2 is provided with two first mounting positions 13, two display windows 12, and two driving protrusions 11. The two first mounting positions 13 are located at both ends (i.e., the upper and lower ends) of the cover plate 1 along its length. The two display windows 12 are located at both ends of the cover plate 1 along its length, and the two driving protrusions 11 are located at both ends of the cover plate 1 along its length. The display window 12, driving protrusion 11, and first mounting position 13 at each end are adjacent to each other. Thus, the user can install a light guide 6 on one of the first mounting positions 13 at each end and a limiting member 7 on the other, choosing to fix the upper end for pressing with the lower end, or fix the lower end for pressing with the upper end. Alternatively, both light guides 6 can be installed to achieve the requirement of pressing at both ends, or both limiting members 7 can be installed to disable one of the cover plates 1. Of course, as in other embodiments, three, four, or more first mounting positions 13 can be provided at different positions on the cover plate 1.

[0075] Preferably, the thickness of the limiting member 7 is greater than the thickness of the light guide member 6. When the cover plate 1 is pressed at the corresponding position and near the limiting member 7, the larger thickness of the limiting member 7 abuts against the first pressure plate 2 or the cover plate 1, which can reduce the rotation angle of the cover plate 1, prevent the cover plate 1 from continuing to rotate, and prevent the cover plate 1 from driving the micro switch 41 at the corresponding position.

[0076] And / or, the limiting member 7 is provided with a drive blocking part, the drive blocking part and the drive protrusion 11 are corresponding in the thickness direction of the wall switch. When the cover plate 1 and the corresponding position of the limiting member 7 are pressed and the drive blocking part of the limiting member 7 abuts against the corresponding drive protrusion 11, preventing the cover plate 1 from continuing to rotate, so that the drive protrusion 11 cannot drive the micro switch 41 corresponding to it.

[0077] And / or, the limiting member 7 is provided with a first drive through hole blocking part, the first drive through hole blocking part and the first drive through hole 21 are corresponding in the thickness direction of the wall switch. When the cover plate 1 and the corresponding position of the limiting member 7 are pressed and nearby, the first drive through hole blocking part of the limiting member 7 abuts against the corresponding drive protrusion 11, preventing the drive protrusion 11 from extending into the first drive through hole blocking part, preventing the cover plate 1 from continuing to rotate, so that the drive protrusion 11 cannot drive the micro switch 41 corresponding to it.

[0078] In another embodiment, the wall switch is also provided with a driving member. The driving protrusion 11 of the cover plate 1 indirectly drives the micro switch 41 through the driving member. When the limiting member 7 is installed in the first mounting position 13, it can limit the driving member so that when the cover plate 1 is pressed, the cover plate 1 cannot drive the corresponding micro switch 41.

[0079] Obviously, various different limiting elements 7 can be set to directly or indirectly limit the rotation of the cover plate 1, so that the driving protrusion 11 cannot press the micro switch 41.

[0080] Preferred, such as Figures 4-6As shown, in this embodiment, the first mounting position 13 is located on the side of the cover plate 1 facing the first pressure plate 2, and the first mounting position 13 includes a limiting frame 131; the light guide 6 includes a fixing body 61 fixedly mounted to the limiting frame 131, and a first light-inlet portion 62 and a first light-outlet portion 63 connected to both ends of the fixing body 61 in the length direction, and the first light-inlet portion 62 is located on the side of the fixing body 61 facing the light-emitting element 42 and extends towards the light-emitting element 42, and the first light-outlet portion 63 is located on the side of the fixing body 61 facing the light-emitting element 42 and extends towards the light-emitting element 42, and the first light-outlet portion 63 is located on the side of the fixing body 61 facing the light-emitting element 42. One side of the display window 12 extends toward the display window 12. The first light-inlet portion 62 corresponds to the first light-guiding hole 22 on the first pressure plate 2, and the first light-outlet portion 63 corresponds to the display window 12. The first light-inlet portion 62 and the first light-outlet portion 63 are used to guide light from the light-emitting element 42 to the display window 12 and improve the light guiding intensity. In this embodiment, the first light-guiding hole 22 is misaligned with the display window 12, and the first light-inlet portion 62 and the first light-outlet portion 63 are also misaligned. The limiting member 7 includes a mounting body 71 that is fixedly installed with the limiting frame 131. Figure 5 A schematic diagram of the structure of the limiting member 7 in an embodiment of this application is shown. Figure 6 A schematic diagram of the structure of the light guide 6 in an embodiment of this application is shown.

[0081] Preferred, such as Figure 4 and Figure 6 As shown, the limiting frame 131 has a U-shaped structure and a first notch 132. The display window 12 is located outside the limiting frame 131 and on one side of the first notch 132. The fixing body 61 includes a first extension 66 extending out of the first notch 132, and the first light-emitting part 63 is located on the first extension 66. The sidewalls of the limiting frame 131 facing the first notch 132 include two first hooks 133 bending towards the first notch 132. The two sides of the fixing body 61 of the light guide 6 in the width direction include two limiting staggers 64, and the two first hooks 133 limit the two limiting staggers 64. Of course, in other embodiments, the limiting frame 131 may not be a U-shaped structure, but may be an elliptical structure, etc. In a less desirable embodiment, it is also possible to provide two opposing protrusions on the sidewalls of the limiting frame 131 facing the first notch 132, which is also within the scope of protection of this application. Of course, the limiting misalignment platform 64 on both sides of the fixed body 61 can also be replaced by a notch or a groove. The two first hook parts 133 can be inserted into the notch or groove to achieve the same fixing effect, which will not be described in detail here.

[0082] Furthermore, such as Figure 4As shown, the first mounting position 13 also includes a first limiting protrusion 134, which is located on one side of the first notch 132, and the display window 12 is located between the first limiting protrusion 134 and the first notch 132, for limiting one end of the light guide 6 in the length direction.

[0083] The inner wall of the limiting frame 131 includes a plurality of second limiting protrusions 135, which squeeze and limit the light guide 6 and the limiting member 7, thereby enhancing the stability of the light guide 6 and the limiting member 7.

[0084] After the light guide 6 is installed in the first mounting position 13, the fixed body 61 and the limiting frame 131 are fixedly installed. Multiple second limiting protrusions 135 on the inner wall of the limiting frame 131 clamp the fixed body 61. The first limiting protrusion 134 limits one end of the fixed body 61 in the length direction. Two first hook parts 133 extend into two limiting misalignments 64 to fix the light guide 6, which can improve the stability of the light guide 6 after it is installed in the first mounting position 13. The first light emitting part 63 extends into the display window 12, and the first light entering part 62 faces the first light guiding hole 22 of the first pressure plate 2.

[0085] Furthermore, such as Figure 6 As shown, a first reflective inclined surface 65 is provided at the connection position between the first light-inlet section 62 and the fixed body 61. Preferably, a second reflective inclined surface (not shown in the figure) is also provided at the connection position between the first light-outlet section 63 and the fixed body 61. The first reflective inclined surface 65 and the second reflective inclined surface are used to reflect the light entering the first light-inlet section 62 to the first light-outlet section 63, and then transmit it out from the display window 12.

[0086] Preferred, such as Figure 4 and Figure 5 As shown, the limiting member 7 also includes an operating part 72 of a columnar structure that is perpendicularly connected to the mounting body 71. The operating part 72 facilitates the installation and removal of the limiting member 7. The side of the mounting body 71 facing the first pressure plate 2 is the limiting part. The operating part 72 is connected to the limiting part. The mounting body 71 is installed in the limiting frame 131 of the first mounting position 13. The operating part 72 corresponds to the first light guide hole 22. When the cover plate 1 is pressed, the operating part 72 extends into the first light guide hole 22. The limiting part abuts against the upper surface of the first pressure plate 2, restricting the cover plate 1 from continuing to rotate, so that the driving protrusion 11 cannot drive the micro switch 41.

[0087] After the limiting component 7 is installed in the first mounting position 13, the mounting body 71 is fixedly installed with the limiting frame 131 and located inside the limiting frame 131. Multiple second limiting protrusions 135 on the inner wall of the limiting frame 131 clamp the mounting body 71 and fix the limiting component 7, which can improve the stability of the limiting component 7 after it is installed in the first mounting position 13.

[0088] Furthermore, such as Figures 4-6 As shown, in this embodiment, the limiting frame 131 of the first mounting position 13 and the mounting body 71 of the limiting member 7 are both rectangular structures, and the first light-entering part 62, the first light-exiting part 63 and the operation part 72 are all columnar structures.

[0089] Of course, in other possible implementations, the fixing body 61 and the mounting body 71 can also be cylindrical structures or other structures for fixed installation with the first pressure plate 2 or the cover plate 1. The first light-inlet part 62 and the first light-outlet part 63 can also be other structures for transmitting light sources. The operating part 72 can also be other operating structures that facilitate the installation of the limiting member 7. The limiting part of the limiting member 7 that contacts the first pressure plate 2 or the cover plate 1 can also be not just a plane, but can also be provided with a structure for abutting against the first pressure plate 2 or the cover plate 1. For example, it is also possible to provide a boss on the plane, which will not be elaborated further.

[0090] Furthermore, such as Figure 4 As shown, in the thickness direction of the wall switch, the length of the driving protrusion 11 is greater than the thickness of the mounting body 71 of the limiting member 7, and the thickness of the mounting body 71 of the limiting member 7 is greater than the thickness of the fixing body 61 of the light guide 6. This means that when the limiting member 7 is set at the first mounting position 13, and the limiting member 7 abuts against the upper surface of the first pressure plate 2, the driving protrusion 11 on the cover plate 1 cannot drive the micro switch 41 to close or open. When the light guide 6 is set at the first mounting position 13, the fixing body 61 of the light guide 6 abuts against or does not abut against the upper surface of the first pressure plate 2, so that the driving protrusion 11 on the cover plate 1 can drive the micro switch 41 to close or open.

[0091] Preferably, the wall switch includes a receiving slot (not shown in the figure) for accommodating excess light guide 6 and / or limiting member 7. When not in use, at least one of the light guide 6 and at least one limiting member 7 can be placed in the receiving slot for easy retrieval and placement.

[0092] Furthermore, the receiving groove is located near the rotation axis of the first pressure plate 2 and / or the second pressure plate 3 and / or the mounting box 5 and / or the cover plate 1.

[0093] Preferred, such as Figure 1 As shown, at least one cover plate 1 is rotatably mounted on the first pressure plate 2.

[0094] like Figure 3 and Figure 4As shown, the first pressure plate 2 includes at least two locking shafts 23, and the cover plate 1 is provided with two first buckles 14 on the side facing the first pressure plate 2. The two first buckles 14 are rotatably engaged with the two locking shafts 23. The first pressure plate 2 includes at least two locking holes or locking grooves. The locking shafts 23 are located in the locking holes. The first buckles 14 include two clamping arms, and a locking ring is formed between the two clamping arms. The locking ring is engaged with the locking shafts 23, and the two clamping arms clamp the locking shafts 23.

[0095] Furthermore, such as Figure 3 As shown, at least one elastic element 24 is provided between the first pressure plate 2 and the cover plate 1. The elastic element 24 is used to drive the cover plate 1 to reset. In this embodiment, at least one elastic element 24 is provided on the side of the first pressure plate 2 facing the cover plate 1. The first pressure plate 2 includes at least one elastic through hole 25. The at least one elastic element 24 and the at least one elastic through hole 25 correspond one-to-one along the thickness direction of the wall switch. One end of the elastic element 24 is integrally injection molded and connected to the first pressure plate 2, and the other end is movably disposed and extends toward the cover plate 1. When the elastic element 24 is subjected to force, it can extend into the elastic through hole 25. The elastic element 24 generates elastic force through plastic deformation to drive the cover plate 1 to reset. Of course, in other embodiments, the elastic element 24 can also be a compression spring, torsion spring, tension spring, or elastic silicone pad, etc. Fixing the compression spring, torsion spring, tension spring, or elastic silicone pad between the first pressure plate 2 and the cover plate 1 can also achieve the effect of driving the cover plate to reset, which is also within the scope of protection of this application and will not be described in detail.

The side of the mounting box 5 where the first inner buckle groove 51 or first inner buckle hole is provided has at least one third limiting protrusion 52. The at least one third limiting protrusion 52 and the at least one first limiting notch 26 limit each other after being limited, thereby limiting the movement of the first pressure plate 2 and the mounting box 5 in the thickness direction of the wall switch.

[0098] Preferred, such as Figure 1 As shown, the circuit board 4 is installed inside the mounting box 5, and the second pressure plate 3 is snapped together with the mounting box 5 to limit the movement of the circuit board 4 in the thickness direction of the wall switch.

The extension arm 33 is provided with a second snap-fit ​​protrusion 34. The mounting box 5 includes at least one extension arm through hole 54.

At least one second snap-fit ​​protrusion 34 is snapped into at least one second snap-fit ​​hole or second snap-fit ​​groove in a one-to-one correspondence.

[0101] Furthermore, such as Figure 9 As shown, the mounting box 5 includes an integrally formed mounting bracket 55 and mounting frame 56. The surface area of ​​the mounting bracket 55 is larger than that of the mounting frame 56. Two mounting platforms 57 extend towards each other from opposite sides of the mounting bracket 55. Each mounting platform 57 is provided with screw holes 58. At least one extension arm through hole 54 is located at the connection position between the mounting bracket 55 and the mounting frame 56. The second snap-fit ​​hole or the second snap-fit ​​groove is provided on the outer side wall of the mounting frame 56. As another embodiment, a separate mounting bracket 55 can also be provided, that is, the mounting bracket 55 and the mounting box 5 are separately provided and fixedly connected.

[0102] Furthermore, such as Figure 3 , Figure 7 and Figure 8 As shown, the first pressure plate 2 has two screw through holes 27 on both sides and two first clearance notches 35 on both sides. The circuit board 4 has two second clearance notches 43 on both sides.

After the second pressure plate 3 and the mounting box 5 are fixedly installed, the two first clearance notches 35 and the two mounting platforms 57 limit each other. The two screw through holes 27 of the first pressure plate 2 and the screw holes 58 of the two mounting platforms 57 correspond one-to-one along the thickness direction of the wall switch. The screws pass through the screw through holes 27, screw holes 58 and the outer wall of the mounting box 5 in sequence and are fixedly installed with the wire trough box.

[0103] Preferred, such as Figure 1As shown, the wall switch includes at least one decorative panel 15, which is fixedly installed with the cover plate 1. The cover plate 1 has a panel mounting groove 16 on the side facing away from the first pressure plate 2. The decorative panel 15 and the panel mounting groove 16 can be installed by, but are not limited to, snap-fit ​​or glue. The decorative panel 15 is provided with at least one second display window 17, which corresponds to the display window 12 on the cover plate 1 in the thickness direction of the wall switch.
