The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0025] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] Reference will now be made to Figure 1 to Figure 6The embodiment of the application discloses a kind of ultra-thin switch, which includes key plate 1, key frame 2, switch pressing plate 3 and back cover 4, key plate 1 connects the front surface of key frame 2, the back surface of key frame 2 is connected with the front surface of switch pressing plate 3 to form first installation cavity, the back surface of switch pressing plate 3 is connected with back cover 4 to form second installation cavity, swing assembly is installed in first installation cavity, on-off component 6 is installed in second installation cavity, swing assembly includes swing lever 51 and swing arm 52 connected with swing lever, swing lever 51 is connected with on-off component, swing arm 52 drives swing lever 51 to swing with the pressing of key plate 1, and the on-off of on-off component 6 is realized in turn.The switch forms two installation cavities by key frame 2 and switch pressing plate 3, switch pressing plate 3 and back cover 4, swing assembly is installed in first installation cavity, on-off component 6 is installed in second installation cavity, which helps to realize the integration and modularization of components, so as to further reduce the overall thickness of the switch, space can be more effectively utilized, so that the thinning of switch thickness is further realized while the functionality is maintained, and meanwhile, the design of partition installation helps to maintain the structural strength of the switch.

[0027] In a specific embodiment of the embodiment, the swing lever 51 is provided in a T-shaped structure, and the horizontal two ends of the swing lever 51 are swingably installed on the back surface of the key frame 2. One end of the swing lever 51 away from the key frame 2 is provided with a V-shaped groove 511, and the V-shaped groove 511 is swingably connected with the on-off component.

[0028] The on-off component 6 includes a swing piece 61, a first metal sheet 62 and a second metal sheet 63. The first metal sheet 62 is provided with a convex column 64 sleeved with the swing piece 61. One end of the swing piece 61 is provided with a W-shaped gap 611. The inside of both sides of the opening of the V-shaped groove 511 is provided with a clamping structure matched with the W-shaped gap 611. The V-shaped groove 511 swings with the swing lever 51 to drive the swing piece 61 to press or move away from the second metal sheet 63, so as to realize the on-off of the second metal sheet 63 and the first metal sheet 61.

[0029] Traditional pendulum rods achieve on / off switching by oscillating the end of the contact plate against the surface of the plate. Over time, the surface of the plate is prone to wear and scratches, leading to adhesive stripping. In this embodiment, the V-groove 511 on the pendulum rod has engaging structures on both sides that match the W-shaped notch 611 on the plate. When the V-groove 511 swings backward with the pendulum rod, the upper side of the V-groove 511 presses down on the plate 61 and engages with the W-shaped notch 611, causing the plate 61 to abut against the second metal piece 63, thus connecting the first metal piece 62 and the second metal piece 63. When the V-groove 511 swings backward with the pendulum rod 51, the lower side of the V-groove 511 pushes the plate 61 upward and engages with the W-shaped notch 611, causing the plate 51 to disengage from the second metal piece 63, thus disconnecting the first metal piece 62 and the second metal piece 63. That is, the rocker arm 51 is provided with a V-shaped groove 511. Through the engagement of the V-shaped groove 511 with the W-shaped notch 611 on the rocker plate, the rocker arm 51 can move the rocker plate 61 back and forth when swinging, so as to realize the on / off control of the switch. Thus, the rocker arm 51 will not cause the rocker plate 61 to lose glue during assembly and use, resulting in the failure of the switch function.

[0030] The aforementioned switching assembly 6 also includes two mounting bases 65, with the first metal piece 62 and the second metal piece 63 respectively connected and fixed to one mounting base 65. To further reduce the overall thickness of the switch, the rear cover 4 is provided with a positioning port 41 for positioning and installing the mounting base 65, further saving space in the second mounting cavity and facilitating the wiring connection between the switching assembly and the outside.

[0031] In one specific implementation of this embodiment, the button frame 2 includes a mounting frame 21 and mounting plates 22 connected to two opposite sides of the mounting frame. The rocker arm 51 is mounted on the mounting plate 22. The rocker arm 51 has contact portions 512 extending from both horizontal ends. Each of the two contact portions 512 is linked to a rocker arm 52. When the button plate 1 is pressed, it drives the rocker arm 52 to swing, thereby the rocker arm 52 contacts or moves away from the contact portion 512 to drive the rocker arm to swing.

[0032] The switch plate 3 has an opening 31 on its back. The switching assembly 6 passes through the opening 31 and connects to the lever 51 in the first mounting cavity. In this way, the switching assembly 6 is installed from back to front, and the metal plates 61 and 62 on the switching assembly 6 do not need to extend too long for external wires, which can greatly reduce the overall thickness of the switch.

[0033] The switch plate 3 has a support frame 7 on its outer perimeter, and the support frame 7 is connected to the button frame 2.

[0034] The support frame 7 can further support the structural members of the switch, and can ensure that the switch is easily and firmly fixed on the wall, prevents the switch from shaking or falling off during use, and improves the overall appearance and stability of the switch.

[0035] In a specific implementation of the embodiment, a small swing angle design is adopted, and the swing angle between the key plate 1 and the key frame 2 is 1.8°, which significantly reduces the space occupation of the switch during operation, thereby helping to realize the ultra-thin design.

[0036] The swing arm angle of the swing arm 52 is 13°, and the swing lever angle of the swing lever 51 is 5.2°. The conventional switch directly uses a transmission mode to drive a contact piece to realize conduction. This structure requires a large-angle driving stroke to enable normal transmission of switch current. This large-angle switch is prone to jamming and stopping work. The swing angle of the swing assembly of the embodiment is reduced, and the required driving stroke is also shortened. The force exerted by the key plate on the swing assembly is reduced, so that the user does not need to press hard, the noise of pressing is reduced, the user experience is improved, and after the switch is installed on the wall, the appearance of the exposed operating part on the wall is thin, improving the appearance of the installed switch.

[0037] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of protection of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
