[0003] Existing panel-mounted switches often face several problems in use, such as assembly complexity and insufficient insulation performance, which may lead to safety risks such as poor contact and leakage. Furthermore, although panel-mounted switches are designed to simplify installation, in practice, if the panel opening size does not match the switch body or if the installation is improper, it may result in insecure installation and poor sealing, thus affecting the switch's performance. In addition, regarding stability and lifespan, traditional panel-mounted switches typically use a simple snap-fit ​​structure for fixing, which may loosen over long-term use, causing poor contact, deteriorated operating feel, or even switch detachment, thereby affecting the normal use of the equipment.

[0019] Figure 1 This is a perspective view of a preferred embodiment of the present invention.

[0020] Figure 2 This is a schematic diagram of the single-side structure of this utility model.

[0021] The components include: 1. Switch operating part; 2. Ring-shaped locking step edge; 3. Insulating outer shell; 4. Second recessed part; 5. Second wiring structure; 6. First recessed part; 7. Elastic buckle; 8. First wiring structure. Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] See Figure 1 A preferred embodiment of a snap-fit ​​button switch is provided. In this embodiment, the button switch is used for embedding on a metal plate. A circular mounting hole is pre-formed on the corresponding metal plate to match the button switch. After the button switch is pre-wired, it can be directly aligned with the mounting hole and pressed in to complete the assembly operation.

[0024] The switch body of the push-button switch is mainly composed of an insulating outer shell 3, which is made of high-quality insulating material to ensure good insulation performance and effectively prevent safety hazards such as leakage. The main body of the insulating outer shell 3 is designed as a regular cylindrical body with a closed bottom, and the interior of the cylinder is used to encapsulate the switch functional components. In this embodiment, the regular cylindrical body is a cylinder that matches the circular mounting hole on the metal plate to enable insertion assembly at the circular mounting hole. The upper edge of the regular cylindrical body extends outward to form an annular locking step 2, and the surface of the annular locking step 2 has a reserved assembly part for the switch operating part 1.

[0025] In this embodiment, the switch operation unit 1 is a push-button limit switch unit, and the user can realize the switch function by operating the switch operation unit 1.

[0026] The insulating outer shell 3 has two first recesses 6 formed in the middle of the column at the lower part of the corresponding annular locking step 2. The two first recesses 6 are positioned opposite each other, and elastic buckles 7 are formed at the lower part of the first recesses 6. These elastic buckles 7 are upwardly curved and outwardly flared buckles. The base of the elastic buckle 7 is fixedly connected to the lower part of the first recess 6, and the upper edge matches the annular locking step 2, together forming a combined locking structure. This design requires that the outer radial dimension of the elastic buckle 7 is larger than the outer radial dimension of the regular cylindrical body, so that the elastic buckle 7 can be elastically deformed inward by the pressure of the mounting plate surface during installation. When the elastic buckle 7 crosses the mounting plate surface, the elastic buckle 7 returns to its original shape, thus locking into the mounting plate surface, achieving a tight locking between the switch and the mounting plate surface. This design not only simplifies the installation process, but also ensures a firm connection between the switch and the mounting plate surface, effectively avoiding problems such as insecure installation and detachment. Meanwhile, the top surface of the free end of the elastic buckle 7 is formed with anti-slip texture, which further enhances the stability and reliability of the snap-fit, so that the switch can be firmly snapped into the assembly plate, effectively avoiding the problem of insecure installation.

[0027] In another embodiment, considering the strength and structural stability of the elastic buckle 7, in addition to optimizing the material and size structure of the insulating housing 3, it is also possible to form reinforcing ribs at the connection position between the base of the elastic buckle 7 and the first recess 6 to enhance the overall strength and stability of the elastic buckle 7, ensuring that it is not easily deformed or damaged during multiple assembly and disassembly processes, thereby extending the service life of the switch.

[0028] In another embodiment, considering that the distance between the top surface of the elastic buckle 7 and the bottom surface of the annular locking step 2 needs to match the thickness of the corresponding mounting plate surface to ensure the tightness and stability of the locking, in another embodiment, the elastic buckle 7 can also be designed as a detachable structure on the insulating housing 3. Its detachable assembly method can be a slot connection or a buckle connection, so as to adapt to mounting plate surfaces of different thicknesses by replacing elastic buckles 7 of different sizes.

[0029] In this embodiment, a set of wiring structures, namely the first wiring structure 8 and the second wiring structure 5, are formed on the bottom surface and the lower side of the insulating housing 3, respectively. These two sets of wiring structures are electrically connected to the switch function component, providing users with convenient wiring operations.

[0030] In this embodiment, the first wiring structure 8 consists of downwardly extending contact pins. The lower ends of these contact pins form contact pads on the bottom surface of the insulating housing 3, facilitating connection with circuit boards or other terminals via solder joints. The second wiring structure 5 is located on one side of the lower part of the insulating housing 3, specifically in the second recess 4. It is a plug-in wiring structure, allowing wires to be inserted into plug holes via plug-in connection, and then secured with screws on the bottom surface for a stable connection.

[0031] In order to reduce the interference of the elastic clip 7 on the wiring of the second wiring structure 5 in the second recess 4, the position of the second recess 4 is perpendicular to the corresponding plane of the first recess 6. This design ensures the independence of the wiring structure, avoids mutual interference during installation and use, and further improves the reliability and practicality of the switch.

[0032] In practical applications, users can choose to use either the first wiring structure 8 or the second wiring structure 5 for wiring operations as needed. The existence of two wiring structures provides users with more wiring options and convenience, making the push-button switch more flexible and reliable in terms of electrical connection, thereby improving the convenience and efficiency of wiring.

[0033] To achieve the above wiring method, there are two implementation methods in different embodiments:

[0034] One is that the first wiring structure 8 and the second wiring structure 5 are respectively equipped with contact pins, and then electrically connected to the switch function component through the contact pins.

[0035] Secondly, the contact pins of the first wiring structure 8 and the second wiring structure 5 are integrated into a T-shaped structure. Under this structural feature, the upper end of the contact pin is electrically connected to the switching function component, while the lower end extends downwards from the closed surface of the insulating housing to form the first wiring structure 8, which is used for connection to external circuits or other wiring terminals. The side branch of the contact pin extends from the lower side of the insulating housing 3, with a reserved wiring socket, which is the second wiring structure 5, to facilitate the connection of wires by plugging in.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
