Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a detachable switch. Background Technology

[0002] The internal circuit board of the free-adhesive switch contains a power supply component and a wireless communication module. The wireless communication module wirelessly connects to a gateway or electrical device, allowing wireless control of the device via the switch. Because the free-adhesive switch has a built-in power supply and does not require a high-voltage power connection, it can be freely pasted and installed in any desired location according to personal habits and preferences.

[0003] While batteries can be installed inside switches, existing technology uses ribs to keep the batteries within the casing. However, this makes the batteries prone to loosening and falling off when the switch is pressed, and dust can easily get in, thus reducing battery performance. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a free-attach switch that prevents the battery from falling off and enhances the battery's dustproof effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This application provides a free-mount switch, comprising a cover plate, a pressure plate, a circuit board, and a switch base stacked sequentially. The circuit board is electrically connected to a power supply, a wireless communication module, and at least one micro switch.

[0007] The pressure plate is provided with at least one first through hole, which corresponds to at least one micro switch. A pressing element is installed in each first through hole, and the at least one pressing element acts on at least one micro switch.

[0008] The circuit board has a second through hole, and the pressure plate has a third through hole corresponding to the second through hole. The power supply is installed in the second and third through holes and is electrically connected to the circuit board. A power supply protective cover is installed in the third through hole.

[0009] In one possible implementation, the power supply protective cover includes a covering surface, and the side of the covering surface is provided with a first buckle and a first boss protruding from the covering surface at intervals. A first groove is provided on the side wall of the third through hole, and a limiting rib is provided on the back of the pressure plate. The first boss is correspondingly installed in the first groove, and the first buckle extends into the back of the pressure plate and abuts against the limiting rib along the thickness direction of the pressure plate.

[0010] In one possible implementation, the pressure plate further includes a strip-shaped elastic through hole located on the side of the limiting rib away from the third through hole and parallel to the limiting rib.

[0011] In one possible implementation, a circular rib is provided on the back of the power supply protective cover, an clearance groove is provided in the switch base, a support rib is provided at the bottom of the clearance groove, the circular rib abuts against the top of the power supply, and the support rib abuts against the bottom of the power supply.

[0012] In one possible implementation, the upper surface of the power supply cover is flush with the upper surface of the pressure plate, or the upper surface of the power supply cover is located within the third through hole.

[0013] In one possible implementation, the power supply includes a positive terminal located on the side and a negative terminal located at the bottom. The circuit board is electrically connected with a negative terminal connector and a positive terminal connector. The negative terminal connector extends from the back of the circuit board and extends to the center of the second through hole. The positive terminal connector extends from the back of the circuit board and extends to the side of the second through hole. The power supply is interference-fitted into the second through hole. The side of the power supply is interference-fitted with the positive terminal connector to achieve electrical connection. The bottom of the power supply is electrically connected to the negative terminal connector.

[0014] In one possible implementation, the cover plate has two second latches spaced apart on the side facing the pressure plate. Each second latch includes two latch arms with a latch groove between them. The pressure plate has a latch shaft corresponding to the second latches. The latch shaft is installed in the latch groove, and the two latch arms clamp the latch shaft, allowing the cover plate and the pressure plate to be rotated. The rotation axis of the cover plate is located on the plane of the pressure plate, or the rotation axis of the cover plate is located inside the pressure plate.

[0015] In one possible implementation, two first fixing posts are spaced apart inside the switch base, and two first notches are provided on both sides of the circuit board. The two first notches are correspondingly locked onto the two first fixing posts. The first fixing posts are hollow structures and include first through holes. A fourth through hole is spaced apart on the pressure plate, and the fourth through hole corresponds to the first through hole.

[0016] In one possible implementation, the circuit board is provided with at least one light-emitting element, and the cover plate is provided with at least one display window. The at least one display window and the at least one light-emitting element correspond one-to-one, and each light-emitting element and each display window corresponds to a pressing element, wherein the pressing element is a light-transmitting elastic pressing element.

[0017] In one possible implementation, the pressing member includes a first mounting portion and a second mounting portion, the first mounting portion protruding from the second mounting portion, and the first mounting portion being interference-fitted into a first through hole in the pressure plate.

[0018] Compared to existing arbitrarily attached switches, this invention comprises a cover plate, a pressure plate, a circuit board, and a switch base stacked sequentially. The circuit board is electrically connected to a power supply, a wireless communication module, and at least one microswitch. The pressure plate has several first through holes, each corresponding to at least one microswitch. A pressing element is installed within each first through hole, and each pressing element acts on at least one microswitch. The circuit board also has second through holes, and the pressure plate has third through holes corresponding to the second through holes. A power supply protective cover is installed within the third through hole. The power supply protective cover prevents the power supply from loosening or falling off when the cover plate is pressed, improving the power supply's dustproof capability and protecting it. The power supply protective cover also facilitates battery replacement.

[0019] Furthermore, when the power supply protective cover is installed in the third through hole, the two first protrusions are installed in the two first grooves respectively. Pressing the power supply protective cover causes it to plastically deform. The first buckle extends into the back of the pressure plate. The back of the pressure plate is provided with a limiting rib. The first buckle and the limiting rib abut against each other along the thickness direction of the pressure plate. The limiting rib enhances the plastic deformation effect of the power supply protective cover, making the power supply protective cover more firmly installed.

[0020] Furthermore, the pressure plate also includes a strip-shaped elastic through hole, which is located on the side of the limiting rib away from the third through hole and parallel to the limiting rib. The elastic through hole in the pressure plate improves the elasticity of the structure between the elastic through hole and the third through hole. In this embodiment, the elastic through hole specifically enhances the elasticity of the limiting rib, allowing the limiting rib to plastically deform, facilitating the installation and removal of the power supply protective cover.

[0021] Furthermore, the pressing component in this application is a light-transmitting elastic pressing component made of light-transmitting elastic material, which can simultaneously serve as an elastic reset and a light guide post, eliminating the need for a separate light guide post, reducing the number of parts and the overall thickness.

Detailed Implementation

[0038] 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.

[0039] like Figures 1-15 As shown, the free-adhesive switch provided in this application includes a cover plate 1, a pressure plate 2, a circuit board 3, and a switch base 4 stacked sequentially. The circuit board 3 is electrically connected to a power supply 5, a wireless communication module (not shown in the figure), and at least one micro switch 31. The wireless communication module can receive and send commands, and can wirelessly control electrical equipment or other devices by controlling the free-adhesive switch. The pressure plate 2 has several first through holes 21, and a pressing element 32 is installed in each first through hole 21. At least one pressing element 32 passes through at least one first through hole. 21 acts on at least one microswitch 31. The switch base 4 includes a base groove, and the back of the pressure plate 2 includes a circuit board receiving groove. The circuit board 3 and the pressure plate 2 are installed in the base groove. The circuit board 3 is located between the bottom of the base groove and the pressure plate 2, and is located in the circuit board receiving groove on the pressure plate 2. The surface area of ​​the cover plate 1 is larger than that of the pressure plate 2. The cover plate 1 is rotatably installed on the pressure plate 2 and cooperates with the switch base 4 to wrap the pressure plate 2 and the circuit board 3. The overall structure is compact, easy to install, and highly reliable. The back of the pressure plate 2 is the side facing the switch base 4. Figure 1 An exploded view of the electronic wall switch of this application is shown.

[0040] The circuit board 3 has a second through hole 37, and the pressure plate 2 has a third through hole 23 corresponding to the second through hole 37. The power supply 5 is installed in the second through hole 37 and the third through hole 23 and is electrically connected to the circuit board 3. Part of the power supply 5 is located in the second through hole 37 and part is located in the third through hole 23.

[0041] Compared to existing technologies, the overall thickness of the free-adhesive switch of this utility model is thinner, making it smaller, lighter, and more in line with current aesthetic needs.

[0042] Preferred, such as Figure 1 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, the pressure plate 2 includes a third through hole 23, which can accommodate part of the power supply 5. A power supply protective cover 51 is installed in the third through hole 23 of the pressure plate 2. After the power supply 5 is installed or replaced, the power supply protective cover 51 is installed in the third through hole 23 from the front of the pressure plate 2. The power supply protective cover 51 can prevent the power supply 5 from loosening or falling off when the cover plate 1 is pressed, prevent dust from entering, improve the dustproof capability of the power supply 5, and protect the power supply 5. At the same time, the power supply protective cover 51 also facilitates battery replacement.

[0043] And it will not increase the thickness. Specifically, the front side of the pressure plate 2 faces the cover plate 1. Figure 6 This is a structural diagram of the front of pressure plate 2. Figure 7This is a structural diagram of the back of pressure plate 2. Figure 10 This is a structural diagram of the front of the power supply protective cover 51. Figure 11 This is a structural diagram of the back of the power supply protective cover 51.

[0044] Furthermore, the upper surface of the power supply protective cover 51 is flush with the upper surface of the pressure plate 2 (that is, the side of the pressure plate 2 facing the cover plate 1), which reduces the grooves between the power supply protective cover 51 and the pressure plate 2, prevents dust accumulation, further improves the dustproof effect of the power supply 5, and the flush structure makes the power supply protective cover 51 look more aesthetically pleasing after it is installed on the pressure plate 2.

[0045] Furthermore, such as Figure 4 As shown, the upper surface of the power supply protective cover 51 is located inside the third through hole 23 and is not flush with the upper surface of the pressure plate 2.

[0046] Preferably, the pressing member 32 in this application is a light-transmitting elastic pressing member made of light-transmitting elastic material, which can simultaneously serve as an elastic reset and a light guide post, eliminating the need for a separate light guide post, reducing the number of parts and the overall thickness. Figure 8 and Figure 9 These are schematic diagrams of the front and back sides of the pressing member 32 in this embodiment.

[0047] Preferred, such as Figure 1 , Figure 3 and Figure 4 As shown, the cover plate 1, pressure plate 2, circuit board 3, and switch base 4 are all rectangular structures. The height of the switch base 4 is greater than the thickness of the pressure plate 2. In a preferred embodiment, the depth of the base groove is greater than the thickness of the pressure plate 2. The circuit board 3 is installed in the base groove, and the pressure plate 2 covers the circuit board 3. The circuit board 3 is located in the circuit board receiving groove, which can further reduce the thickness of the electronic wall switch. Figure 3 A longitudinal sectional view of the electronic wall switch in this embodiment is shown. Figure 4 A cross-sectional view of the electronic wall switch in this embodiment is shown.

[0048] Preferred, Figures 13-15 As shown, the base groove includes a circuit board mounting groove. The four groove walls of the circuit board mounting groove protrude to form a first rectangular rib 41, and the four groove walls of the pressure plate 2 protrude to form a second rectangular rib 24. The length and width of the second rectangular rib 24 are greater than the length and width of the first rectangular rib 41. The circuit board 3 is installed in the circuit board mounting groove, and the circuit board receiving groove on the back of the pressure plate 2 wraps around the circuit board mounting groove. That is, the second rectangular rib 24 wraps around the first rectangular rib 41.

[0049] Furthermore, the second rectangular rib 24 abuts against the bottom of the base groove.

[0050] Furthermore, such as Figure 10 and Figure 11 As shown, the power supply protective cover 51 includes a covering surface. The covering surface has an installation structure and two first protrusions 512 spaced apart on its sides. The installation structure includes a first buckle 511 protruding from the covering surface. The two first protrusions 512 extend outwards from both sides of the covering surface. Two first grooves 231 are provided on the two side walls of the third through hole 23 of the pressure plate 2. When the power supply protective cover 51 is installed in the third through hole 23, the two first protrusions 512 are correspondingly installed in the two first grooves 231. Pressing the power supply protective cover 51 causes it to plastically deform, and the first buckles 511 extend into the back of the pressure plate 2. In a preferred embodiment, the back of the pressure plate 2 is provided with a limiting rib 232, and the first buckles 511 and the limiting rib 232 abut against each other along the thickness direction of the pressure plate 2. The limiting rib 232 enhances the plastic deformation effect of the power supply protective cover 51, making the power supply protective cover 51 more securely installed.

[0051] When replacing the power supply 5, the cover plate 1 can be removed, and a flathead screwdriver or other tools can be used to pry open the mounting structure of the power supply protective cover 51 to plastically deform the power supply protective cover 51. After the first buckle 511 separates from the limiting rib 232, it can extend from the back of the pressure plate 2, thereby removing the power supply protective cover 51 and taking out the power supply 5 through the third through hole 23, making the disassembly and replacement of the power supply 5 simple.

[0052] Preferred, such as Figure 6 and Figure 7 As shown, the pressure plate 2 also includes a strip-shaped elastic through hole 29. The elastic through hole 29 is located on the side of the limiting rib 232 away from the third through hole 23 and is parallel to the limiting rib 232. The elastic through hole 29 on the pressure plate 2 improves the elasticity of the structure between the elastic through hole 29 and the third through hole 23. In this embodiment, the elastic through hole 29 is specifically used to enhance the elasticity of the limiting rib 232, allowing the limiting rib 232 to plastically deform, facilitating the installation and removal of the power supply protective cover 51.

[0053] Preferred, such as Figures 12-14As shown in this embodiment, the power source 5 is a button cell battery. The bottom surface area of ​​the button cell battery is smaller than its top surface area. The side and top of the button cell battery are the positive terminal 52, and the bottom of the button cell battery is the negative terminal 53. The power source 5 is installed in the second through hole 37 of the circuit board 3. The circuit board 3 is electrically connected to a negative terminal connecting piece 34 and a positive terminal connecting piece 35. The negative terminal connecting piece 34 extends from the back of the circuit board 3 to the middle of the second through hole 37, and the positive terminal connecting piece 35 extends from the back of the circuit board 3 to the side of the second through hole 37. The power source 5 is interference-fitted into the second through hole 37. The side of the power source 5 is interference-fitted with the positive terminal connecting piece 35 to achieve electrical connection, and the bottom of the power source 5 is electrically connected to the negative terminal connecting piece 34. The back of the circuit board 3 faces the switch base 4. Figure 12 This is a schematic diagram of the power supply 5 in an embodiment of this application. Figure 13 A schematic diagram of the front structure of circuit board 3 is shown. Figure 14 A schematic diagram of the structure on the back of circuit board 3 is shown.

[0054] Furthermore, such as Figure 11 As shown, a circular rib 513 is provided on the back of the power supply protective cover 51. The power supply 5 is installed with its bottom (i.e., negative terminal) facing down in the second through hole 37. After the power supply protective cover 51 is installed in the third through hole 23, the circular rib 513 abuts against the top (i.e., positive terminal) of the power supply 5, which can squeeze and limit the power supply 5. By squeezing the power supply 5, the electrical connection between the negative terminal 53 and the negative terminal connecting piece 34 can also be made more stable.

[0055] Furthermore, such as Figure 15 As shown, the bottom of the circuit board mounting slot of the switch base 4 is provided with a clearance groove 44, which corresponds to the position of the power supply 5. After the circuit board 3 is installed in the switch base 4, the clearance groove 44 is used to avoid the power supply 5. The bottom of the clearance groove 44 is provided with a support rib 45, for example, which can be Figure 15 The cross-shaped rib shown in the diagram, the supporting rib 45 abuts against the negative terminal of the power supply 5, making the electrical connection between the negative terminal of the power supply 5 and the negative terminal connecting piece 34 more stable.

[0056] Furthermore, such as Figure 15 As shown, two first fixing posts 42 are spaced apart in the circuit board mounting slot, and two first notches 36 are provided on both sides of the circuit board 3. After the circuit board 3 is installed in the circuit board mounting slot, the two first notches 36 are correspondingly locked on the two first fixing posts 42, which can limit and fix the circuit board 3. The first fixing posts 42 on both sides of the circuit board mounting slot are hollow structures, including a first through hole. A through hole plug 43 is installed in the first through hole to close the through hole. The first through hole can be used for heat dissipation or for installation and fixation. For example, it can be fixed by passing a mounting screw through the first through hole.

[0057] Furthermore, such as Figures 13-15 As shown, the circuit board 3 has multiple mounting holes 38 spaced apart on its upper surface, and the switch base 4 has multiple mounting protrusions 39 spaced apart on its circuit board mounting groove. These protrusions 39 are installed within the mounting holes 38. This design is used to confine the circuit board 3 within the switch base 4, preventing the circuit board 3 from shaking.

[0058] Preferred, such as Figure 1 and Figure 13 As shown, the circuit board 3 is provided with at least one light-emitting element 33, and the cover plate 1 is provided with at least one display window 11. The at least one display window 11 and the at least one light-emitting element 33 correspond one-to-one, and each light-emitting element 33 and each display window 11 correspond to a pressing element 32.

[0059] Furthermore, the light-emitting element 33 can be positioned near the micro switch 31, sharing a pressing element 32 with the micro switch 31.

[0060] Furthermore, such as Figure 1 As shown in this embodiment, two light-emitting elements 33 are spaced apart in the middle of the circuit board 3. Correspondingly, the pressure plate 2 has a first through hole 21 and a pressing element 32 at the corresponding position. Two display windows 11 corresponding to the light-emitting elements 33 are spaced apart in the middle of the cover plate 1. The light-emitting elements 33 may be, but are not limited to, LED lights.

[0061] Preferably, the pressing component 32 in this application is a light-transmitting silicone pad. The silicone pad is elastic, soft to the touch, and transparent, and can act as a light guide to transmit the light source of the light-emitting component 33. When the micro switch 31 is triggered, the light-emitting component 33 lights up, which can indicate to the outside world that it is working through the pressing component 32. At the same time, the silicone pad can be inserted into the first through hole 21 with an interference fit, making installation and disassembly convenient. On the other hand, because the silicone pad is elastic, after the silicone pad is forced to drive the micro switch 31 to act, the silicone pad returns to its original shape, driving the cover plate 1 to reset, replacing the reset component in the prior art, saving internal space of the arbitrarily attached switch, and reducing the size of the arbitrarily attached switch. The display window 11 can exist in the form of a through hole, or it can be provided with a transparent cover, or a silicone pad can also be provided in the through hole.

[0062] Furthermore, such as Figure 5 , Figure 8 and Figure 9As shown, at least one driving part 12 is provided on the side of the cover plate 1 facing the pressure plate 2. Each driving part 12 corresponds to at least one pressing member 32. The driving part 12 is a protrusion extending from the side of the cover plate 2 facing the pressure plate 2. The pressing member 32 has a driving groove 321 that mates with the driving part 12. The back of the driving groove 321 is a received groove 322 that mates with the micro switch 31. The driving part 12 can extend into the driving groove 321 of the pressing member 32, and the micro switch 31 extends into the received groove 322. When the cover plate 1 is pressed, the driving part 12 acts on the micro switch 31 through the pressing member 32. Since the pressing member 32 of this application is a translucent silicone pad, it has a soft touch and provides a better pressing experience.

[0063] Furthermore, such as Figure 6 and Figure 8 As shown, the pressing member 32 includes a first mounting portion 323 and a second mounting portion 324. The first mounting portion 323 and the second mounting portion 324 are arranged in a stepped manner, that is, the first mounting portion 323 protrudes from the second mounting portion 324. The first mounting portion 323 of the pressing member 32 is interference-fitted into the first through hole 21 of the pressure plate 2. The two sidewalls opposite to the first mounting portion 323 include a first concave-convex structure 325. The first concave-convex structure 325 includes a plurality of alternating grooves and protrusions. The two sidewalls opposite to the first through hole 21 of the pressure plate 2 include a second concave-convex structure 325 that cooperates with and limits the first concave-convex structure 325. The second concave-convex structure 211 includes multiple alternating grooves and protrusions. The protrusions of the second concave-convex structure 211 extend into the grooves of the first concave-convex structure 325, and the protrusions of the first concave-convex structure 325 extend into the grooves of the second concave-convex structure 211. By providing the first concave-convex structure 325 on the pressing member 32 and providing the second concave-convex structure 211, which cooperates with and limits the first concave-convex structure 325, the contact area between the pressing member 32 and the first through hole 21 can be increased, thereby increasing the friction force. The pressing member 32 is more firmly fixed after being installed in the first through hole 21. The first mounting part 323 and the second mounting part 324 of the pressing member 32 can be formed by stamping, which is simple, efficient, and low in cost.

[0064] Preferred, such as Figure 1 As shown in the embodiment of this application, four micro switches 31 are spaced apart on the circuit board 3, four first through holes 21 are correspondingly provided on the pressure plate 2, four pressing parts 32 are respectively installed in the four first through holes 21, and four driving parts 12 are correspondingly provided on the cover plate 1.

[0065] Furthermore, in other embodiments, the arbitrarily attachable switch includes multiple side-by-side cover plates 1, each cover plate 1 having at least two display windows 11. Each of the at least two display windows 11 corresponds to at least two pressing elements 32, and each of the at least two pressing elements 32 corresponds to at least two microswitches 31 and at least two light-emitting elements 33. The presence of at least two microswitches 31 provides better tactile feedback and a more sensitive response when pressing the cover plate 1, while the presence of at least two light-emitting elements 33 provides better light-guiding effect.

[0066] Preferred, such as Figure 5 and Figure 6 As shown, a second buckle 13 is provided on the side of the cover plate 1 facing the pressure plate 2. The second buckle 13 includes two buckle arms and a buckle groove is provided between the two buckle arms. The pressure plate 2 is provided with a buckle shaft 25 corresponding to the second buckle 13. The buckle shaft 25 is installed in the buckle groove. The two buckle arms clamp the buckle shaft 25, so that the cover plate 1 and the pressure plate 2 are rotated and fixed by the buckle structure. The rotation axis of the cover plate 1 is located on the plane of the pressure plate 2, or the rotation axis of the cover plate 1 is located inside the pressure plate 2. Lowering the position of the rotation axis of the cover plate 1 can reduce the gap between the cover plate 1 and the pressure plate 2, thereby reducing the thickness of the arbitrarily attached switch.

[0067] Furthermore, such as Figure 5 and Figure 6 As shown, the cover plate 1 has two second buckles 13 on both sides of its back, and two retaining pins 25 extend from both sides of the pressure plate 2. The cover plate 1 is rotatably mounted on the pressure plate 2.

[0068] Furthermore, the arbitrarily attachable switch of this application includes three cover plates 1 arranged side by side, with the retaining shafts 25 extending from both sides of the pressure plate 2. Four retaining holes 26 or two retaining slots are spaced apart in the middle of the pressure plate 2, and retaining shafts 25 are provided in the retaining holes 26 or retaining slots. The cover plates 1 located on both sides of the pressure plate 2 correspond to a retaining shaft 25 extending to one side and a retaining shaft 25 provided in the retaining hole 26 or retaining slot, respectively. The cover plate 1 located in the middle of the pressure plate 2 corresponds to the retaining shaft 25 in the retaining hole 26 or retaining slot. The rotation axes of the three cover plates 1 are located in the plane of the pressure plate 2. Lowering the position of the rotation axis of the cover plates 1 can reduce the thickness of the arbitrarily attachable switch.

[0069] Preferred, such as Figure 7 and Figure 15As shown, two protruding third buckles 46 are respectively provided at intervals on the outer sides of the two opposite ribs of the first rectangular rib 41 of the circuit board mounting groove. A third through hole 47 is opened at the bottom of the circuit board mounting groove at the position of the third buckle 46. Two third protrusions 27 are respectively provided at intervals on the inner sides of the two opposite ribs of the second rectangular rib 24 on the back of the pressure plate 2. The third protrusions 27 protrude towards the switch base 4, and a third slot 28 is opened on the third protrusion 27. The opening of the third slot 28 is opposite to the third buckle 46. The pressure plate 2 and the switch base 4 are snapped together along the thickness direction of the switch base 4. The four third buckles 46 are respectively snapped into the corresponding third slots 28. The third protrusions 27 of the pressure plate 2 extend into the third through hole 47 of the switch base 4, which has a better limiting and fixing effect. The circuit board 3 is located between the pressure plate 2 and the switch base 4. The pressure plate 2 can squeeze the circuit board 3 to limit and fix it.

[0070] Preferred, such as Figure 6 and Figure 7 As shown, the pressure plate 2 has a fourth through hole 22 spaced apart, which corresponds to the first through hole on the switch base 4. The fourth through hole 22 allows the wall switch to be removed from its mounting position (e.g., the wall) without disassembling the pressure plate 2 by removing the mounting screws.

[0071] Furthermore, the pressure plate 2 may also include two fixing plugs, which are respectively embedded in the two fourth through holes 22. Setting the fixing plugs to block the fourth through holes 22 can prevent foreign objects from entering and improve the safety of the electronic wall switch. In a preferred embodiment, the fixing plugs are made of silicone, which is easy to install and disassemble.

[0072] Preferably, the bottom surface of the switch base 4 is provided with adhesive, such as 3M adhesive, which can be pasted at any desired installation location without drilling holes in the wall, making installation and disassembly simpler and more convenient.

[0073] Preferably, the surface of the switch base 4 is provided with an anti-static adhesive sheet to dissipate static charge and improve the safety performance of the arbitrarily attached switch. The anti-static adhesive sheet is mainly made of conductive materials, static dissipative materials, and synthetic rubber through various processes. It generally has a two-layer structure, with an inner conductive layer and an outer static dissipative layer. The anti-static adhesive sheet can prevent static-sensitive devices from being disturbed by electrostatic discharge, thereby achieving the effect of electrostatic protection and preventing damage to the devices.
