[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 6, is a thin swing switch device according to an embodiment of the present invention, comprising a base 100 , a button 200 , a movable contact piece 300 and a swing structure 400 . The button 200 is rotatably arranged on the base body 100 and can swing relative to the base body 100. The rotation axis of the button 200 is arranged along the front-to-back direction, and two toggle parts 210 are arranged side by side on the left and right of the button 200; the dynamic contact piece 300 is rotatably arranged on the base body 100; the upper end of the swing structure 400 is rotatably arranged on the base body 100 and the rotation axis is arranged along the front-to-back direction, the rotation axis of the swing structure 400 is located below the rotation axis of the button 200, and the lower end of the swing structure 400 abuts against the dynamic contact piece 300, and the swing structure 400 is provided with a toggle matching part 410, which is located between the two toggle parts 210, and the toggle matching part 410 is spaced apart from the rotation axis of the swing structure 400; wherein, auxiliary abutment parts 450 are respectively provided on the left and right sides of the swing structure 400, and the button 200 can abut against the auxiliary abutment part 450 and drive the swing structure 400 to swing.

[0035] When the switch device is in use, the key 200 swings, and the toggle portion 210 pushes the toggle mating portion 410, causing the swing structure 400 to swing, pushing the contact piece 300 to swing and control the on / off state. If the swing structure 400 does not swing into place, the key 200 will directly push the auxiliary abutment portion 450 during its swing, causing the auxiliary swing structure 400 to swing to a predetermined angle, allowing the switch device to stably enter the on / off state, thereby making the control on / off capability of the thin swing switch device more stable. In this switch device, the key 200 area can be made larger, and the noise is reduced. The switch device is compact and reduces space occupation.

[0036] Specifically, when the button 200 pushes the auxiliary abutment 450 on the left side of the swing structure 400, the swing structure 400 swings to the right. At this time, the button 200 is separated from the auxiliary abutment 450 on the right side of the swing structure 400, which facilitates the smooth rotation of the swing structure 400; when the button 200 pushes the auxiliary abutment 450 on the right side of the swing structure 400, the swing structure 400 swings to the left. At this time, the case is separated from the auxiliary abutment 450 on the left side of the swing structure 400, which facilitates the smooth rotation of the swing structure 400.

[0037] Specifically, the left and right sides of the toggle matching portion 410 are in contact with the two toggle portions 210 respectively.

[0038] In this embodiment, the auxiliary abutment 450 is a rod, the lower end of which is located below the rotation axis of the swing structure 400, and the upper end of which is positioned toward the key 200. The lower side of the key 200 is provided with two pressing protrusions 220, which are opposite the auxiliary abutment 450. The auxiliary abutment 450 is a rod, and the key 200 contacts the upper end of the rod by pressing the protrusions 220, thereby assisting in driving the swing structure 400 to rotate. This makes the swing structure 400 compact and saves manufacturing materials.

[0039] Specifically, the pressing protrusion 220 is a block protruding from the underside of the key 200, and the auxiliary abutment 450 is an L-shaped rod, which provides good force transmission and is relatively easy to manufacture. It is conceivable that in other embodiments, the auxiliary abutment 450 may also be a plate, with a downwardly facing pressure rod disposed on the underside of the key 200. When the key 200 swings, the pressure rod contacts the plate, causing the swing structure 400 to swing.

[0040] In this embodiment, the lower end of the auxiliary abutment portion 450 is located between the rotation axis of the swing structure 400 and the toggle-matching portion 410. With the above structure, when the key 200 swings at a small angle, the auxiliary abutment portion 450 can also enable the swing structure 400 to swing at a large angle. Furthermore, when the toggle portion 210 and the toggle-matching portion 410 are operating normally, the key 200 does not contact the auxiliary abutment portion 450, resulting in relatively smooth transmission between the swing structure 400 and the key 200. It is understood that the lower end of the auxiliary abutment portion 450 can also be located at other positions on the swing structure 400, and those skilled in the art can configure the position according to actual needs.

[0041] In this embodiment, the base 100 includes a switch bracket 110 and a mounting block 120. The upper end of the swing structure 400 is rotatably connected to the mounting block 120. The button 200 is located on the upper side of the switch bracket 110, and the mounting block 120 is mounted on the lower side of the switch bracket 110. The swing structure 400 is indirectly mounted to the switch bracket 110 via the mounting block 120, which facilitates assembly of the swing structure 400 with the base 100 and the production process of the switch bracket 110.

[0042] Specifically, the swing structure 400 has a rotating shaft, and the mounting block 120 has an axial hole. The rotating shaft passes through the axial hole, allowing the swing structure 400 to be rotatably connected to the mounting block 120. The switch bracket 110 has a plug slot 113 defined on its underside. The mounting block 120 is inserted into the plug slot 113 and engages with the slot wall of the plug slot 113, achieving a stable assembly of the mounting block 120 and the switch bracket 110. The assembly structure is relatively simple.

[0043] It is conceivable that the swing structure 400 can be provided with an axis hole, and the mounting block 120 can be provided with a rotating shaft, and the rotating shaft is passed through the axis hole, so that the swing structure 400 is rotatably connected to the mounting block 120; the mounting block 120 can be installed on the switch bracket 110 by screw locking or magnetic attraction.

[0044] In this embodiment, the switch bracket 110 is provided with a first clearance hole 111 and a second clearance hole 112. The toggle portion 210 is provided through the first clearance hole 111, and the button 200 abuts against the auxiliary abutting portion 450 through the second clearance hole 112. Through the first and second clearance holes 111, 112, when the button 200 located on the upper side of the switch bracket 110 swings, the toggle portion 210 can pass through the first clearance hole 111 and directly drive the toggle mating portion 410, causing the swing structure 400 to rotate, which is direct, reliable, and compact. Similarly, if the swing structure 400 has not swung into position, the button 200 can also push the auxiliary abutting portion 450 through the second clearance hole 112, causing the swing structure 400 to swing into position, which is direct, reliable, and compact.

[0045] In this embodiment, the base 100 further includes a switch rear seat 130, which is connected to the switch bracket 110 and encloses a housing cavity within which the movable contact 300 and the swinging structure 400 are located. The housing cavity formed by the switch rear seat 130 and the switch bracket 110 encases the movable contact 300 and the swinging structure 400. Both the switch bracket 110 and the switch rear seat 130 provide protection for the movable contact 300 and the swinging structure 400, ensuring greater stability during use.

[0046] Specifically, the switch rear base 130 is assembled and connected to the switch bracket 110 by snapping. The movable contact piece 300 is rotatably mounted on the switch rear base 130. It is conceivable that the switch rear base 130 can also be assembled with the switch bracket 110 through other structures, such as by screwing the switch rear base 130 and the switch bracket 110.

[0047] In this embodiment, the base 100 further includes a mounting bracket 140, which is connected to the switch bracket 110 and is provided with screw-locking holes 141. The mounting bracket 140 is frame-shaped and surrounds the outer perimeter of the switch rear base 130. Mounting bracket 140 allows screws to be inserted through screw-locking holes 141 to secure the mounting bracket 140 and the switch bracket 110 to the wall base box, simplifying installation. The frame-shaped mounting bracket 140 facilitates avoiding the switch rear base 130, allowing the switch device to be thinner while maintaining good structural strength.

[0048] Specifically, the switch bracket 110 and the switch rear seat 130 are usually made of plastic with good insulation performance, and the mounting frame 140 can be made of metal to improve the overall strength of the base body 100 and facilitate the base body 100 to be relatively firm when installed on the bottom box.

[0049] Specifically, the mounting bracket 140 is mounted on the switch bracket 110 by snapping. It is conceivable that the mounting bracket 140 can also be mounted on the switch bracket 110 by screw locking or other methods.

[0050] In the embodiment, the swing structure 400 includes a swing member 420, an elastic member 430, and a telescopic member 440. The upper end of the swing member 420 is rotatably connected to the base 100. The swing member 420 is provided with a guide hole 421, the opening of the guide hole 421 facing the movable contact piece 300. The telescopic member 440 is telescopically arranged in the guide hole 421. The lower end of the telescopic member 440 abuts against the movable contact piece 300. The elastic member 430 is located in the guide hole 421, one end of the elastic member 430 abuts the bottom of the guide hole 421, and the other end of the elastic member 430 abuts against the telescopic member 440. When the swing structure 400 swings, in order to prevent the lower end of the swing structure 400 from pushing the contact piece 300 out of position, the telescopic member 440 cooperates with the elastic member 430 to ensure that the telescopic member 440 can maintain a certain force to push the contact piece 300, thereby ensuring that the swing of the swing structure 400 can be stably transmitted to the movable contact piece 300, and the switch has better stability in use.

[0051] Specifically, the auxiliary abutment portion 450 is provided on the swing member 420, the elastic member 430 is a spring, and the telescopic member 440 is slidably connected to the guide hole 421. It is conceivable that the elastic member 430 can also be a spring, a silicone block, or other elastic structure, and those skilled in the art can configure it according to actual needs.

[0052] In this embodiment, the left and right sides of the toggle mating portion 410 are respectively provided with curved surfaces 411. The toggle portion 210 is strip-shaped, and the two curved surfaces 411 slide and engage with one side of the two toggle portions 210 in a one-to-one correspondence. When the key 200 swings, the strip-shaped toggle portion 210 pushes the toggle mating portion 410, causing a small amount of relative sliding. Therefore, the left and right sides of the toggle mating portion 410 slide and engage with the two toggle portions 210 via the curved surfaces 411, ensuring relatively smooth transmission between the key 200 and the swing structure 400 and preventing wear on the toggle portion 210 and the toggle mating portion 410.

[0053] In an embodiment, the switch device further includes two static contact pieces 500. The middle part of the moving contact piece 300 is rotatably connected to the base body 100, and the rotation axis is arranged in the front-rear direction. The two static contact pieces 500 are respectively disposed on the left and right sides of the rotation axis of the moving contact piece 300, and the contact ends of the static contact pieces 500 are located above the moving contact piece 300. The layout of the above-mentioned static contact pieces 500 and moving contact piece 300 enables the moving contact piece 300 to conduct or cut off with the static contact piece 500 in an upwardly tilted contact manner. There is more space for arranging the static contact pieces 500, which is beneficial to reducing the vertical size of the switch device, that is, reducing the thickness of the switch device.

[0054] Specifically, the switch rear seat 130 is further provided with three wiring terminals 600, wherein two wiring terminals 600 are respectively and electrically connected to the two static contact pieces 500 in a one-to-one correspondence, and the other wiring terminal 600 is electrically connected to the moving contact piece 300.

[0055] Specifically, a rotating shaft is provided on the upper side of the switch bracket 110, and a card slot for embedding the rotating shaft is provided on the lower side of the button 200. The rotating shaft is embedded in the card slot, so that the button 200 can rotate relative to the switch bracket 110.
