[0026] Compared with the embodiments of the prior art in which a mounting plate is provided, the present application does not provide a mounting plate. Without reducing the structural strength, the number of parts is reduced, making the wall switch thinner. By providing a panel mounting slot on the mounting frame, the panel is at least partially installed in the panel mounting slot, thereby reducing the thickness of the wall switch and improving the aesthetics. By providing the mounting hole in the panel mounting slot, the panel and the mounting frame are rotatably connected to completely cover the panel mounting slot. When the wall switch and the wire trough box are installed, only the panel needs to be removed to fix the wall switch and the wire trough box, making installation and disassembly simpler. By setting the upper surface of the pressure plate as a pressure plate arc surface, the distance from the pressure plate arc surface, the first arc surface or the second arc surface to the panel is gradually reduced, which can increase the swing angle of the panel and the button assembly while reducing the thickness of the wall switch.

The disassembly brims facilitate the disassembly of the panel, and the third shielding plates are used to shield the inside of the wall switch, which has dust-proof and safety protection functions. The connection position between the upper surface of the mounting frame and the panel mounting groove forms two opposite first notches. When the disassembly brims are against the first notches, the disassembly brims are at least partially located in the first notches, limiting the swing angle of the panel. When the wall switch is in the on and off states, the cooperation between the disassembly brims and the first notches is used to weaken the thickness of the disassembly brims, so that the transition between the upper surface of the panel and the upper surface of the mounting frame is smooth when they contact, and the distance between the panel and the mounting frame is reduced, thereby reducing the thickness of the wall switch and improving the aesthetics.

[0028] In addition, the two sides of the panel mounting slot include two first clips, and the first clips include an avoidance groove or an avoidance hole, and a card shaft arranged in the avoidance groove or the avoidance hole, so that the card shaft is located below the upper surface of the panel mounting slot. The position of the card shaft is lowered through the avoidance groove or the avoidance hole so that the rotating shaft of the panel is located below the panel mounting slot, which can reduce the thickness of the wall switch.

[0029] In addition, the button assembly includes a button, a spring and a push rod. The push rod can slide in the spring mounting groove and can swing relative to the push rod driven part within a certain range. In this way, the panel and the button assembly only need to rotate a small angle to drive the push rod driven part to swing past the equilibrium position. The push rod driven part can also swing a certain angle relative to the push rod, driving the moving contact to swing a larger angle to increase the opening distance and improve the insulation distance.

[0030] In addition, a slide plate is added between the panel and the pressure plate. The panel drives the slide plate to rotate and slide, and the slide plate drives the button assembly to swing at a large angle, and then the button assembly drives the moving contact to contact or separate with the static contact. Only one component is added, and the height of the exposed mounting position of the switch is reduced; at the same time, the side of the slide plate facing the pressure plate also includes two driving arms, and the button includes two passive arms. The two driving arms of the slide plate drive the two passive arms of the button to indirectly drive the button to swing, so that the slide plate slides with less displacement and the panel swings at a smaller angle, further realizing a larger swing of the button, and then realizing the connection and disconnection of the switch, reducing the swing angle of the wall switch, making the wall switch appear thinner, and improving the overall aesthetics. It is simple to assemble, low cost, easy to implement and has stable performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present utility model. The protection scope of the present utility model is not limited to the description of the following embodiments.

[0056] like Figure 1 and Figure 2 As shown, a wall switch includes a button assembly 1, a pressure plate 2, a contact assembly 3, a mounting frame 4 and a panel 5.

[0057] The mounting frame 4 is sequentially provided with a first baffle 431, a panel mounting slot 41, and a second baffle 432 along a first direction. A first curved surface 413, a contact assembly mounting slot 36, and a second curved surface 414 are sequentially provided within the panel mounting slot 41 along a second direction. The contact assembly 3 is mounted within the contact assembly mounting slot 36, and two mounting holes 42 are located on the first curved surface 413 and the second curved surface 414, respectively, along the second direction. The contact assembly 3 includes at least one movable contact 32 and at least one stationary contact 34. The pressure plate 2 is mounted within the panel mounting slot 41, covering the contact assembly mounting slot 36. The button assembly 1 is rotatably mounted on the pressure plate 2 and passes through the pressure plate 2 to engage with the movable contact 32. The panel 5 is at least partially located within the panel mounting slot 41 and rotatably connected thereto, and the panel 5 completely covers the panel mounting slot 41. The rotating axis of the panel 5 is disposed within the panel mounting slot 41 along a second direction, with the first direction being perpendicular to the second direction. The panel 5 swings to drive the button assembly 1 to swing, thereby driving the moving contact 32 to contact or separate from the static contact 34 , thereby switching the state of the contact assembly 3 .

[0058] The wall switch of this embodiment has a panel mounting groove 41 provided on the mounting frame 4, and the panel 5 is at least partially installed in the panel mounting groove 41, thereby reducing the thickness of the wall switch and improving the aesthetics; by setting the mounting hole 42 in the panel mounting groove 41, the panel 5 is rotatably connected to the mounting frame 4 to completely cover the panel mounting groove 41. When the wall switch and the wire trough box are installed, it is only necessary to remove the panel 5 to fix the wall switch and the wire trough box, and installation and disassembly are simpler. Compared with the embodiment of the prior art in which a mounting plate is provided, the present application does not provide a mounting plate. Without reducing the structural strength, the number of parts is reduced, making the wall switch thinner.

[0059] Preferably, Figure 1As shown, the mounting frame 4 includes a mounting frame box 44, the panel mounting slot 41 is formed on the mounting frame box 44, and a first shielding plate 431 and a second shielding plate 432 protrude from both sides of the top of the mounting frame box 44. During installation, the mounting frame box 44 extends into the interior of the wire trough box, and the first shielding plate 431 and the second shielding plate 432 protrude from the wire trough box, providing dust and water protection and aesthetically pleasing shielding.

[0060] Further, such as Figure 1 、 Figure 2 As shown, the upper surface of the pressure plate 2 is a pressure plate arc surface, and the pressure plate arc surface, the first arc surface 413 and the second arc surface 414 are symmetrical along the rotation axis of the panel. From the side of the pressure plate arc surface and the first arc surface 413 away from the rotation axis to the side close to the rotation axis, the distance from the pressure plate arc surface, the first arc surface 413 or the second arc surface 414 to the panel 5 gradually decreases, which can increase the swing angle of the panel 5 and the button assembly 1 while reducing the thickness of the wall switch.

[0061] Preferably, Figure 2 and Figure 4 As shown, the panel 5 includes two detachable brims 51 located on both sides of the panel 5 along the first direction, and two third shielding plates 54 respectively connected to the two detachable brims 51. The two third shielding plates 54 extend toward the direction of the pressure plate 2. The two detachable brims 51 extend to both sides along the first direction to protrude from the third shielding plates 54 and are perpendicular to the third shielding plates 54. The detachable brims 51 are provided to facilitate the detachment of the panel 5. The third shielding plates 54 are provided to shield the interior of the wall switch, thereby providing dustproof and safety protection.

[0062] Two opposite first notches 411 are formed at the connection position between the upper surface of the mounting frame 4 and the panel mounting groove 41. During the swinging process of the panel 5, when the disassembled brim 51 abuts against the first notch 411, the disassembled brim 51 is at least partially located in the first notch 411, limiting the swinging angle of the panel 5.

[0063] When the wall switch is in the on and off states, the cooperation between the disassembly brim 51 and the first notch 411 is used to weaken the thickness of the disassembly brim 51, so that the transition between the upper surface of the panel 5 and the upper surface of the mounting frame 4 is smooth when they contact, and the distance between the panel 5 and the mounting frame 4 is also reduced, thereby reducing the thickness of the wall switch and improving the aesthetics.

[0064] Further, such as Figure 2 and Figure 3 As shown, the disassembly brim 51 is a long strip structure or at least a point structure; the first notch 411 is a long strip structure or at least a point structure.

[0065] Preferably, Figure 2 and Figure 3As shown, the panel mounting groove 41 further includes two first panel avoidance grooves 412 located on two side walls of the panel mounting groove 41 perpendicular to the first direction. The panel 5 is at least partially located in the first panel avoidance grooves 412, reducing the thickness of the wall switch.

[0066] Further, such as Figure 2 As shown, the two side walls of the panel mounting groove 41 along the second direction are structural reinforcement walls 415, which are used to enhance the structural strength of the wall switch. The first panel avoidance groove 412 is located on the upper surface of the structural reinforcement wall 415. The two first panel avoidance grooves 412 are connected end to end with the two first notches 411 and have the same depth.

[0067] Preferably, Figure 1 and Figure 4 As shown, the button assembly 1 includes a button 11, a spring 12, and a push rod 13, with the spring 12 connected between the button 11 and the push rod 13. The button 11 has a "T"-shaped structure, including a panel driving portion 111 and a push rod driven portion 112 that are perpendicular to each other. The spring 12 is connected between the push rod driven portion 112 and the push rod 13. Furthermore, the push rod driven portion 112 includes a spring mounting groove, within which the spring 12 is mounted. One end of the push rod 13 is connected to the spring 12, and the other end of the push rod 13 is used to drive the moving contact 32. The push rod 13 is at least partially located within the spring mounting groove.

[0068] Preferably, Figure 5 As shown, the push rod 13 can slide in the spring mounting groove and the push rod 13 can swing within a certain range relative to the push rod active portion 112. In this way, the panel 5 and the button assembly 1 only need to rotate a small angle to drive the push rod active portion 112 to swing past the equilibrium position. The push rod active portion 112 can also swing a certain angle relative to the push rod 13, driving the moving contact 32 to swing a larger angle to increase the opening distance and improve the insulation distance.

[0069] Preferably, Figure 4 As shown, the panel 5 is linked to the button assembly 1, and the side of the panel 5 facing the button assembly 1 includes a first linkage part, which cooperates with the panel driving part 111 of the button assembly 1 to make the panel 5 and the button assembly 1 linked.

[0070] Furthermore, the first linkage portion includes two linkage plates 52 extending toward the button assembly 1, the two linkage plates 52 being oppositely positioned at both ends of the lengthwise direction of the panel drive portion 111; alternatively, the first linkage portion includes four linkage plates 52 extending toward the button assembly 1, two linkage plates 52 being positioned at both ends of the lengthwise direction of the panel drive portion 111, and the other two linkage plates 52 being positioned on both sides of the panel drive portion 111. Of course, other numbers of linkage plates 52 may also be provided.

[0071] Further, such as Figure 1 As shown, the pressing plate 2 includes a first through hole 21 , the push rod 13 passes through the first through hole 21 and is connected to the contact assembly 3 , and the button 11 is rotatably connected to the pressing plate 2 .

[0072] Furthermore, the pressing plate 2 includes a first limiting portion, and the button 11 includes a second limiting portion. The first limiting portion and the second limiting portion cooperate to enable the button 11 to be rotatably connected to the first pressing plate 2.

[0073] Further, such as Figure 1 As shown, the first limiting portion includes two limiting retaining walls 22 protruding from the upper surface of the pressure plate 2. The two limiting retaining walls 22 are arranged opposite to each other and include opposing limiting holes or limiting grooves. The second limiting portion includes limiting protrusions 113 located on both sides of the button 11. The limiting protrusions 113 are rotatably mounted in the limiting holes or limiting grooves. Alternatively, in other embodiments, the two limiting retaining walls 22 include opposing limiting protrusions 113, and the second limiting portion includes limiting grooves located on both sides of the button 11 or a limiting hole that penetrates the button 11.

[0074] Further, such as Figure 4 As shown, the two sides of the middle part of the first through hole 21 include two limit platforms. When the button assembly 1 swings to the closed state, one side of the panel drive part 111 in the length direction is against one limit platform. When the button assembly 1 swings to the open state, the other side of the panel drive part 111 in the length direction is against the other limit platform, limiting the swing angle of the button assembly 1.

[0075] Preferably, Figure 1 and Figure 2 As shown, the panel 5 is rotatably mounted on the mounting frame 4 through a snap-fit structure. The two sides of the panel mounting groove 41 include two first snap-fits 45, which are respectively arranged on the first curved surface 413 and the second curved surface 414 and located outside the two mounting holes 42. The side of the panel 5 facing the mounting frame 4 includes two second snap-fits 53, and the first snap-fits 45 and the second snap-fits 53 are rotatably connected.

[0076] The first clip 45 includes an avoidance groove or avoidance hole, and a card shaft arranged in the avoidance groove or avoidance hole, so that the card shaft is located below the upper surface of the panel mounting groove 41. The position of the card shaft is lowered through the avoidance groove or avoidance hole, so that the rotating shaft of the panel 5 is located below the panel mounting groove 41, which can reduce the thickness of the wall switch.

[0077] The second buckle 53 includes two buckle arms and a bayonet located between the two buckle arms. The clamping shaft is located in the bayonet. The bayonet and the clamping shaft are rotatably matched. The two buckle arms can clamp the clamping shaft.

[0078] Preferably, Figure 1 and Figure 4 As shown, the contact assembly 3 of this embodiment includes three terminals (a first terminal 311, a second terminal 312, and a third terminal 313), a movable contact 32, a support plate 33, and two stationary contacts 34. The two stationary contacts 34 are located above the movable contact 32 along the thickness direction of the wall switch. The movable contact 32 includes two movable contacts at each end, and the stationary contacts 34 include stationary contacts. The two stationary contacts 34 are fixedly connected to the first terminal 311 and the second terminal 312, respectively. The support plate 33 is connected to the third terminal 313 and is vertically supported within the mounting frame 4. The end of the support plate 33 that contacts the movable contact 32 is bent to form a supporting arc surface. The middle portion of the movable contact 32 is supported on the supporting arc surface for seesaw motion. The movable contact 32 and the stationary contacts 34 are preferably made of copper, but aluminum, iron, or other conductive alloy materials are also acceptable.

[0079] Furthermore, the middle portion of the movable contact 32 includes a recessed area 35, and the push rod 13 at least partially extends into the recessed area 35. The panel 5 swings, causing the push rod 13 to swing left and right within the recessed area 35, driving the movable contact 32 to perform a seesaw motion with the supporting arc surface as a fulcrum, causing one end of the movable contact 32 to move upward and the other end to move downward. One end of the movable contact 32 contacts the corresponding static contact 34, and the other end disconnects from the corresponding static contact 34, thereby achieving circuit connection and disconnection. Of course, as another embodiment, the contact assembly 3 can also be provided with only one static contact 34.

[0080] Preferably, Figure 5 As shown, in another embodiment of the button assembly 1, the diameter of the push rod 13 is slightly smaller than the inner diameter of the spring mounting groove, and the push rod 13 can swing slightly relative to the button 11. When the panel 5 is pressed, the panel 5 drives the button assembly 1 to swing, and the button 11 drives the push rod 13 to swing through the spring mounting groove and the spring 12. The push rod 13 slides in the recessed area 35. When the push rod 13 slides to the supporting curved surface of the support plate 33, it reaches the equilibrium position. At this time, the spring 12 is compressed to the extreme. After the push rod 13 slides over the supporting curved surface of the support plate 33, the panel 5 and the button 11 continue to drive the push rod 13 to swing. At the same time, the spring 12 also drives the push rod 13 to swing slightly relative to the button 11, so that the panel 5 and the button assembly 1 only need to rotate a small angle to drive the movable contact 32 to swing a larger angle.

[0081] Preferably, Figure 1 and Figure 2As shown, the pressure plate 2 is snap-connected to the mounting frame 4, and the contact assembly 3 is limited in the contact assembly mounting groove 36. The side of the pressure plate 2 facing the mounting frame 4 includes at least one support plate 23 extending in the direction of the mounting frame 4. The mounting frame 4 includes at least one support hole 46 for the support plate 23 to pass through. The mounting frame 4 includes a snap-on protrusion located near the support hole 46. The support plate 23 includes a snap-on hole or a snap-on groove. The support plate 23 extends into the support hole 46 along the installation direction of the pressure plate 2 and the mounting frame 4, and the snap-on protrusion is snap-connected to the snap-on hole or the snap-on groove; alternatively, the support plate 23 includes a snap-on protrusion and the mounting frame 4 includes a snap-on groove or a snap-on hole, which is also possible and within the scope of protection of this application.

[0082] Furthermore, in this embodiment, the four supporting holes 46 are located in the contact assembly mounting slot 36 .

[0083] Further, such as Figure 2 As shown, the two first buckles 45 are distributed along the second direction on both sides of the contact assembly mounting slot 36. In this embodiment, the two first buckles 45 and the two mounting holes 42 are located in the same straight line.

[0084] Preferably, a silicone pad is provided in the mounting hole 42 , and the silicone pad can perform dust-proof and insulating treatment on the mounting hole 42 .

[0085] Preferably, the static contact 34 includes a plug leg and a contact arm connected at a right angle. The plug legs of the two static contacts 34 are respectively inserted into the first terminal 311 and the second terminal 312 and are relatively parallel. The contact arm is parallel to the bottom surface of the mounting frame 4 and the ends of the contact arms of the two static contacts 34 away from the plug legs are opposite to each other.

[0086] A first support column is positioned within the contact assembly mounting slot 36. The side of the pressure plate 2 facing the mounting bracket 4 includes at least two downward pressure columns. The first support column is positioned between the two downward pressure columns and compresses the contact arm relative to the wall switch along its thickness. This design provides a more stable mounting structure for the stationary contact 34.

[0087] Preferably, Figure 6 As shown, the wall switch also includes a slide plate 6 arranged between the panel 5 and the button 11, the panel 5 and the slide plate 6 are driven to cooperate, the slide plate 6 is connected to the button 11, and the sliding direction of the slide plate 6 is set along the second direction or is set at an angle to the second direction; the slide plate 6 can rotate and slide under the drive of the panel 5 to switch between the first position and the second position and drive the button 11 to swing to switch the state of the contact assembly 3, so that the button 11 can drive the moving contact 32 to contact or separate with the static contact 34.

[0088] Preferably, Figure 6As shown, in this embodiment, a linkage structure is provided between the slide plate 6 and the button 11. The slide plate 6 includes a first driving arm 210 and a second driving arm 220 spaced apart along the second direction. A first driving groove and a second driving groove are provided on both sides of the middle portion of the button 11. A first passive arm 402 and a second passive arm 403 are formed on both sides of the middle portion of the button 11 along the second direction. The first driving arm 210 cooperates with the first passive arm 402 in driving, and the second driving arm 220 cooperates with the second passive arm 403 in driving.

[0089] The slide 6 can rotate and slide under the drive of the panel 5 to switch between the first position and the second position. At the same time, the slide 6 drives the first passive arm 402 through the first driving arm 210 or drives the second passive arm 403 through the second driving arm 220 to drive the button 11 to rotate, so that the button assembly 1 drives the moving contact 32 to contact or separate from the static contact 34. Specifically, when the slide 6 slides and rotates from the second position to the first position, the first driving arm 210 drives the first passive arm 402 to swing the button 11 toward the side close to the first driving arm 210, and the button 11 drives the moving contact 32 to contact with one static contact 34 and separate from the other static contact 34; when the slide 6 slides and rotates from the first position to the second position, the second driving arm 220 drives the second passive arm 403 to swing the button 11 toward the side close to the second driving arm 220, and the button 11 drives the moving contact 32 to separate from one static contact 34 and contact with the other static contact 34.

[0090] A slide plate 6 is added between the panel 5 and the pressure plate 2. The panel 5 drives the slide plate 6 to rotate and slide, and the slide plate 6 drives the button assembly 1 to swing at a large angle, and then the button assembly 1 drives the moving contact 32 to contact or separate with the static contact 34. Only one component is added, and the height of the exposed mounting position of the switch is reduced; at the same time, the side of the slide plate 6 facing the pressure plate 2 also includes two driving arms, and the button 11 includes two passive arms. The two driving arms of the slide plate 6 drive the two passive arms of the button 11 to indirectly drive the button 11 to swing, so that the slide plate 6 slides with less displacement, and the panel 5 swings at a smaller angle, further realizing a larger swing of the button 11, and then realizing the connection and disconnection of the switch, reducing the swing angle of the wall switch, making the wall switch appear thinner, and improving the overall aesthetics. It is simple to assemble, low cost, easy to implement and has stable performance.

[0091] Furthermore, the first driving arm 210 protrudes toward the first passive arm 402 and extends into the first driving slot, and the second driving arm 220 protrudes toward the second passive arm 403 and extends into the second driving slot. This not only increases the swing angle of the button 11, but also does not increase the thickness of the switch, thereby enhancing the aesthetics of the switch. For example, the swing angle of the button 11 is greater than 4 degrees, while the swing angle of the panel 5 only needs to be 2 degrees or less. Figure 6As shown, a sliding structure is formed between the slide plate 6 and the pressure plate 2 in this embodiment. A first sliding protrusion 205 and a second sliding protrusion 206 are provided on the side of the slide plate 6 facing the pressure plate 2. The first sliding protrusion 205 and the second sliding protrusion 206 are spaced relative to each other along a second direction. The pressure plate 2 is provided with a first guide bevel 207 that slidably cooperates with the first sliding protrusion 205 and a second guide bevel 208 that slidably cooperates with the second sliding protrusion 206. The first guide bevel 207 and the second guide bevel 208 are each arranged at an angle with respect to the second direction. As the slide plate 6 rotates with the panel 5, the first sliding protrusion 205 acts on the first guide bevel 207, or the second sliding protrusion 206 acts on the second guide bevel 208, controlling the slide plate 6 to rotate and slide along the guide bevel on the pressure plate 2. Since the sliding distance of the slide plate 6 is controlled by the angle of the guide bevel on the pressure plate 2, the sliding distance of the slide plate 6 is more precisely controlled, thereby better controlling the swing angle of the button assembly 1 and the movement of the movable contact 32.

[0092] In this embodiment, the panel 5 rotates synchronously with the skateboard 6, and the skateboard 6 can slide relative to the panel 5 and the pressure plate 2 under the drive of the first guide bevel 207 or the second guide bevel 208 of the pressure plate 2. The panel 5 applies a rotational force to the skateboard 6, and the first guide bevel 207 or the second guide bevel 208 applies a sliding force to the skateboard 6.
