Description

Technical Field

[0001] This utility model relates to a switch, specifically a small-angle swing plate switch. Background Technology

[0002] With the increasing number of electrical appliances, switches are used more and more in daily life, and their panels are typically mounted prominently on the wall. The growing demand for personalized home decoration, emphasizing decorative style, has placed new requirements on the design of wall switches. Most existing wall switches are rocker switches. The rocker (usually an integrated structure with the lever) is typically located above the mounting base. Pressing the operating button causes the rocker to swing, which in turn moves the lever. To ensure the lever reaches its designated position, the moving contact in existing switches is usually flat and horizontally positioned. To allow for a certain breaking distance, the lever's swing angle must typically reach approximately 6.5°, which is reflected in the button's swing distance (or angle). Common wall switches have relatively large swing angles for their buttons or operating parts, for example, within the range of + / -3° or 0–6°. A larger button swing angle results in a corresponding increase in the thickness of the outer edge of the switch product exposed above the wall.

[0003] The significant thickness of these switches inevitably results in a large portion of the switch protruding from the wall after installation, occupying considerable space and making the switch more susceptible to damage from impacts, potentially posing a safety hazard. The thicker components also waste materials and create an unattractive overall appearance. Furthermore, existing moving contacts are typically single-point, while double-point moving contacts, where both contacts are installed through the same hole, present challenges in actual production. Applying silver to both sides is difficult, increasing production costs and making the contact itself more difficult to manufacture. Assembling the two silver contacts with the moving contact is also challenging, leading to poor heat dissipation and a shorter product lifespan. Additionally, the double-point moving contact structure uses a staggered double-contact design. While this is simpler to manufacture, the staggered silver points cause inconsistent left-right movement of the moving contact, resulting in performance differences, reduced product reliability, and a worse tactile feel for the user.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings: Depend on Figure 1 Combination Figure 2-8 As shown, a small-angle oscillating plate switch includes a housing 1 and an internal functional component 2. The internal functional component 2 includes a moving contact 3, and further includes: Button 4, located on housing 1, is used to control the swing of movable contact 3; Cover plate 5, the cover plate 5 is provided with a first swing shaft 51, the cover plate 5 is provided on the housing 1 through the first swing shaft 51 and is swing-connected to the housing 1. The swing arm 6 has a second swing shaft 61. The swing arm 6 is mounted on the housing 1 and oscillatingly connected to the housing 1 via the second swing shaft 61. The button 4 is driven by the cover plate 5 to swing the swing arm 6, thereby causing the moving contact 3 to move. The horizontal height of the first swing shaft 51 is higher than the horizontal height of the second swing shaft 61. The beneficial effects of this invention are that the first and second swing shafts, with a height difference between them, allow the swing arm to amplify the swing angle of the button and the cover plate, thereby increasing the movement distance of the moving contact and achieving reliable disconnection. This avoids the button protruding excessively from the wall during use, resulting in a thinner overall product and reduced production costs. This invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life.

[0025] The cover plate 5 is provided with a driving part 52 and a pressing part 53. There are two driving parts 52, which are located on both sides of the second swing shaft 61 of the swing arm. The pressing part 53 is located above the swing arm 6. Specifically, the driving part 52 is located on the outside of the swing arm 6, and there are two pressing parts 53, both of which are located above the swing arm 6. When the button 4 is pressed, the swing arm 6 is pressed by the pressing part 53 on one side of the second swing shaft 61 and driven by the driving part 52 on the other side of the second swing shaft 61 to swing around the second swing shaft 61. When the button is pressed, the pressing part instantly exerts a pressing effect, causing the swing arm to swing. Then, the driving part on the other side drives the swing arm to swing again, thereby increasing the swing distance of the swing arm. This achieves the function of driving the swing arm to swing at a larger angle with a small angle rotation of the button (cover plate), so that the button protrudes less from the mounting surface (wall), making the product more aesthetically pleasing.

[0026] The driving part 52 and the pressing part 53 form a driving groove 54, and the upper part of the second swing shaft 61 and the swing rod 6 are disposed within the driving groove 54. Specifically, the pressing part 53 is arc-shaped, and the end of the swing rod 6 near the driving part 52 is also arc-shaped. The driving groove can accommodate the upper part of the swing rod, facilitating reliable driving of the swing rod side by the driving part, thus ensuring reliable swing rod operation. The arc-shaped pressing part facilitates reliable pressing of the swing rod, and the arc-shaped swing rod side facilitates driving by the driving part, resulting in less interference during product swinging and better product control performance.

[0027] The horizontal height difference between the first swing shaft 51 and the second swing shaft 61 is 8-9 mm. This allows the swing arm to rotate approximately 6.5° when the cover plate rotates by about 2° (existing cover plates typically swing by about 3-6°), thus ensuring the swing of the moving contact piece, reliable circuit switching, and guaranteed product performance. In practice, the horizontal height difference between the first swing shaft and the second swing shaft 61 is 8.2-8.6 mm. Specifically, the distance from the first swing shaft to the contact point between the drive unit and the swing arm is proportional to the distance from the second swing shaft to the contact point between the drive unit and the swing arm, allowing a small-angle swing of the cover plate to generate a large-angle swing of the swing arm.

[0028] The cover plate 5 has a positioning hole 55, and the button 4 has a hook part 41 and a positioning block 42 that matches the positioning hole 55. The hook part 41 is connected to the cover plate 5 so that the button 4 and the cover plate 5 are linked. This structure allows the button and the cover plate to move synchronously. The structure is simple and easy to operate. The positioning hole and positioning block facilitate the installation of the cover plate.

[0029] The hook portion 41 and the button 4 are integrally molded from plastic, or the hook portion 41 is fixed to the button 4. In this utility model, the button can be made of plastic or glass. When the button is made of plastic, it can be integrally molded with the hook portion, which is simple in structure and easy to manufacture. When the plastic part is made of glass or other materials, the hook portion can be fixed to the button, making the product more aesthetically pleasing.

[0030] This utility model also includes a base 21, which is disposed on the housing 1. The internal functional component 2 includes a wiring terminal 22, which is disposed inside the base 21. The wiring terminal 22 is provided with a conductive sheet 23. The button 4 drives the movable contact 3 to connect with the conductive sheets 23 on different terminals to achieve circuit switching by swinging. This structure enables the product to achieve dual control, is simple in structure, and is convenient and reliable in operation. The movable contact and wiring terminal can be installed in the base first, and then fixed to the housing by the base. The structure is simple and easy to assemble.

[0031] The movable contact 3 includes: The contact body 31 is arranged in a sheet shape. The first contact piece 32 is disposed on the contact piece body 31; The first contact point 33 protrudes from the first contact piece 32; The second contact 34 is connected to the contact body 31 and / or the first contact 32; the contact body 31 and / or the first contact 32 are folded outward to extend the second contact 34. The second contact point 35 is disposed on the second contact piece 34; the second contact point 35 protrudes from the second contact piece 34 and is disposed on both sides of the contact piece body 31, respectively, along with the first contact point 33. This invention features a first contact piece and an outwardly folded second contact piece, with the first and second contact pieces respectively providing the first and second contact points. This increases the area of ​​the moving contact piece, improves heat dissipation, enhances product performance stability, and extends product lifespan. Specifically, the second contact point and the first contact point are at the same horizontal level, and a gap 36 is provided between the second and first contact pieces at the second and first contact points. The two contacts of this invention are at the same height and symmetrically arranged, resulting in even force distribution during swinging, better feel, reliable operation, and more stable product performance. Of course, the two contacts can also be on different horizontal planes. The end of the second contact point furthest from the second contact piece and the end of the first contact point furthest from the first contact piece are symmetrically arranged about the contact piece body. The symmetrical arrangement of the two contacts facilitates product processing, ensures stable product performance, and provides a better feel during operation. In fact, the bending of the first contact piece makes the first and second contacts symmetrical about the swing center of the moving contact piece, which makes the product operation smooth and reliable, the operation feel better, and the circuit switching stable and reliable.
