[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that the terms "first," "second," etc., used in this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with this disclosure.

[0022] Please see Figures 1-5 In this embodiment of the utility model, a convenient push button switch includes a housing 1; a circuit board 2 is provided inside the housing 1; a mechanical switch 3 is electrically connected to the center of the circuit board 2; the trigger switch of the mechanical switch 3 is located at the top; a push button cover 4 is slidably provided on the top of the housing 1; a top contact portion 5 is formed at the bottom of the push button cover 4; and the top contact portion 5 contacts the trigger button of the mechanical switch 3, thereby triggering the mechanical switch 3 by pressing any position of the push button cover 4.

[0023] Specifically, by setting a circuit board 2 and installing a mechanical switch 3 inside the housing 1, the electrical signal control is centralized, resulting in a compact and reliable structure. The mechanical switch 3 is located in the middle of the circuit board 2, enhancing the ability to trigger the mechanical switch 3 by pressing it at any position. The trigger button of the mechanical switch 3 is located at the top and contacts the top contact part 5 at the bottom of the button cover 4 that is slidably set on the top of the housing 1. When the user presses any position of the button cover 4, the top contact part 5 can transmit pressure downward to trigger the mechanical switch 3, achieving a sensitive and uniform trigger response, improving the ease of operation and user feel, while avoiding the trigger insensitivity problem caused by the traditional single-point pressing structure. Preferably, when the button cover 4 and the mechanical switch 3 are not triggered, the gap between them can be set to 1 mm. Of course, it can be finely adjusted according to actual needs.

[0024] Furthermore, the cross-section of the top part 5 is cross-shaped.

[0025] Specifically, the cross-section of the top contact part 5 is designed in a cross shape, which allows it to form a multi-directional force support structure when in contact with the trigger button of the mechanical switch 3. This structure not only enhances the overall rigidity and stability of the top contact part 5, but also effectively distributes the pressing force, ensuring that no matter from which direction or position the user presses the button top cover 4, the pressure can be evenly transmitted to the trigger button of the mechanical switch 3, thereby improving the trigger sensitivity and consistency of the button and avoiding malfunctions or incomplete triggering caused by bias pressure.

[0026] Furthermore, the bottom edge of the button top cover 4 is provided with several sliding hooks 6 with an L-shaped cross-section; and the edge of the housing 1 is formed with a through groove 7; and the sliding hooks 6 slide in conjunction with the through groove 7; when the mechanical switch 3 is pressed, the mechanical switch 3 is spring-reset, and the hook part of the sliding hook 6 abuts against the housing 1 to limit the travel of the button top cover 4.

[0027] Specifically, by setting several L-shaped sliding hooks 6 on the bottom edge of the button top cover 4, which slide in conjunction with the through grooves 7 on the edge of the housing 1, stable guidance and controllable sliding of the button top cover 4 are achieved. When the user presses the top cover to trigger the mechanical switch 3, the mechanical switch 3 pushes the top cover back when the spring returns to its original position. During the return process, the hooks of the sliding hooks 6 abut against the edge of the housing 1, thereby limiting the range of motion of the button top cover 4. This design ensures smooth sliding and reliable return of the button, and effectively prevents the top cover from detaching from the housing 1 due to excessive force, thus improving the overall durability and operational safety of the structure.

[0028] Furthermore, a bottom shell 8 is fitted into the bottom of the housing 1; and the bottom shell 8 is formed through several mounting holes 9; it is hung on the wall through the mounting holes 9.

[0029] Specifically, by fitting a bottom shell 8 into the bottom of the main housing 1, a stable connection between the main housing 1 and the bottom structure is achieved, improving the overall structural strength and ease of assembly. Several through-holes 9 on the bottom shell 8 are used for wall mounting, allowing the portable push-button switch to be directly fixed to a wall or panel, making installation simple and quick. This structure not only ensures the stability and reliability of the switch but also makes the overall appearance cleaner and more aesthetically pleasing, facilitating flexible application in various scenarios. When wall-mounted, matching brackets such as screws need to be driven into the wall; when not wall-mounted, it can be placed directly on a table for portable use, requiring only an internal battery power supply.

[0030] Furthermore, the mounting hole 9 is elongated; and the middle part of the mounting hole 9 has an outwardly expanding circular hole portion 10.

[0031] Specifically, the mounting hole 9 adopts an elongated strip structure with an outwardly expanding circular hole 10 in the middle, making the design more adaptable and flexible during installation. The elongated strip hole allows for fine-tuning of the installation position within a certain range, facilitating precise alignment with screws on the wall or mounting bracket; while the expanded circular hole 10 in the middle is used to accommodate screw heads or washers, making the installation more secure and reliable, while preventing the screws from loosening or slipping during long-term use, thereby improving the overall installation stability and service life of the push-button switch.

[0032] Furthermore, the inner wall of the bottom shell 8 is formed with several sliding grooves 11; and the outer wall of the bottom shell 8 is formed with strip blocks 12 corresponding to the sliding grooves 11; and when the bottom shell 8 is installed with the shell 1, the strip blocks 12 slide in along the sliding grooves 11.

[0033] Specifically, by forming several sliding grooves 11 on the inner wall of the bottom shell 8 and strip blocks 12 corresponding to the sliding grooves 11 on the outer wall, a sliding assembly connection between the bottom shell 8 and the shell 1 is achieved. During installation, the strip blocks 12 slide smoothly into the sliding grooves 11, achieving rapid positioning and stable connection. This not only improves the efficiency of assembly and disassembly and facilitates later maintenance or replacement, but also enhances the guiding and seismic performance of the structure through the cooperation between the sliding grooves 11 and the strip blocks 12, ensuring that the bottom shell 8 and the shell 1 are tightly connected and not easily loosened.

[0034] Furthermore, the bottom of the bottom shell 8 is provided with several L-shaped limiting blocks 13; and the bottom of the shell 1 is formed with several insertion holes 14 corresponding to the limiting blocks 13; and by inserting the limiting blocks 13 into the insertion holes 14, the shell 1 and the bottom shell 8 are securely installed.

[0035] Specifically, by setting several L-shaped limiting blocks 13 at the bottom of the inner shell 8, and forming insertion holes 14 at corresponding positions on the bottom of the shell 1, a stable plug-in connection between the two is achieved. During installation, after the limiting blocks 13 are inserted into the insertion holes 14, their L-shaped structures can form an effective mechanical engagement, preventing the shell 1 from loosening or shifting under force or vibration. This not only improves the bonding strength and structural stability between the shell 1 and the bottom shell 8, but also simplifies the assembly process, facilitating quick disassembly and maintenance, and has good practicality and reliability.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
