However, current mouse buttons have fixed travel distances and cannot adapt to the usage habits of specific users, hindering the completion of more precise control tasks in video games and causing inconvenience. Technical issues

[0003] Traditional mice primarily use mechanical contact switches. In practical use, these switches rely mainly on direct contact between contacts to trigger the switch. However, their lifespan is relatively limited due to mechanical or electrical aging. Conventional improvements mainly focus on optimizing the alloy material of the contacts and the structure of the springs, but these solutions are costly and present challenges in subsequent design and manufacturing.

The preferred embodiment of the invention, the embodiment of the invention, and its industrial applicability.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This embodiment, referring to Figures 1-4, specifically implements a magnetically triggered micro switch, including an insulating body 1 and a triggering component. The triggering component includes a button 3, a spring structure, and a magnetic sensor 2 disposed below the button 3. A magnet 4 is disposed inside the button 3. The spring structure includes a bracket and a rocker 5 supported at the bottom of the button 3. The bracket includes a first contact portion 6, a second contact portion 7, a first fulcrum 8, and a second fulcrum 9. One end of the rocker 5 is connected to the first fulcrum 8, and the other end can swing along the first fulcrum 8, so that the end of the rocker 5 away from the first fulcrum 8 can contact the first contact portion 6 or the second contact portion 7. A spring piece 10 for connecting with the second fulcrum 9 is disposed in the middle of the rocker 5.

[0023] Furthermore, a positioning cylinder 12 is provided at the bottom of the button 3, and the magnet 4 is fitted inside the positioning cylinder 12. The positioning cylinder 12 is provided with a receiving groove for fitting and installing the magnet 4. The fitting installation method improves the assembly and production efficiency of the switch.

[0024] The outer peripheral surface of the button 3 is provided with a guide portion, and the insulating body 1 is provided with a guide groove that matches the guide portion, which is used to guide the button 3 and ensure the stability of the button 3 during the pressing process.

[0025] Furthermore, the rocker arm 5 is provided with a first slot 14 and a second slot 15 spaced apart in the middle. The spring piece 10 is integrally bent at one end of the first slot 14, and the other end of the spring piece 10 is connected to the second fulcrum 9. When the rocker arm 5 is pressed by the button 3, the elastic deformation of the spring piece 10 allows the rocker arm 5 to swing along the reset point 8, thereby achieving the trigger feedback effect of the original mechanical contact switch. The positioning cylinder 12 passes through the second slot 15, and a gap is provided between the outer circumferential surface of the positioning cylinder 12 and the inner wall of the second slot 15 to ensure that the rocker arm 5 is not interfered with by the positioning cylinder 12 during swinging, thus ensuring the flexibility and stability of the rocker arm 5's swing. The provision of the first slot 14 and the second slot 15 not only provides space for the installation of the spring piece 10, but also provides a certain stroke range for the swing of the rocker arm 5, allowing the rocker arm 5 to accurately contact the first contact part 6 or the second contact part 7 to realize the closing or opening of the switch.

[0026] Furthermore, one end of the rocker 5 is provided with a contact point 11 for contacting the first contact part 6 or the second contact part 7. The contact method of the contact point 11 can significantly enhance the trigger feedback effect when the button 3 is pressed.

[0027] Furthermore, the first fulcrum 8 and the second fulcrum 9 are respectively provided with V-shaped grooves for engaging with the rocker arm 5 and the spring contact 10. The spring contact 10 engages with the V-shaped grooves via U-shaped grooves. This snap-fit ​​installation method facilitates the quick installation and removal of the rocker arm 5 and the spring contact 10, improving the assembly efficiency and maintenance convenience of the switch. The V-shaped groove design also effectively prevents the rocker arm 5 and the spring contact 10 from loosening or falling off during use, ensuring the stability and reliability of the switch.

[0028] Furthermore, the spring 10 has an arc-shaped structure. This arc-shaped design allows the spring 10 to undergo uniform elastic deformation when subjected to external forces, thereby ensuring that the rocker 5 can swing smoothly and improving the triggering sensitivity and stability of the switch. The arc-shaped structure of the spring 10 can also effectively disperse the effects of external forces on the spring 10, extending its service life.

[0029] Compared to traditional mechanical contact switches, this invention employs a contactless magnetic induction triggering mechanism, resulting in a longer service life and higher stability. It avoids the wear and electrical aging problems caused by direct contact of the mechanical contacts 11, significantly improving the switch's durability. Furthermore, the magnetic induction triggering mechanism allows for precise adjustment of the trigger stroke, providing a more personalized operating experience for different users. Secondly, this invention retains the impact-effect rebound structure on top of the magnetic induction triggering mechanism, enabling the micro switch to achieve both contactless triggering and the trigger feedback of the original mechanical contact switch, greatly enhancing the user experience.

[0030] The magnetic sensor 2 is disposed inside the insulating body 1 and corresponds to the magnet 4. When the button 3 is pressed, the magnet 4 moves with the button 3, changing the distance between it and the magnetic sensor 2, thereby triggering the magnetic sensor 2 to output an electrical signal, realizing the trigger control of the micro switch.

[0031] The magnetic sensor 2 is preferably a Hall sensor, AMR sensor, GMR sensor, or TMR sensor. When the button 3 is pressed, the magnet 4 moves with the button 3 into the sensing range of the Hall sensor, thereby triggering the switch action. In addition, the spring 10 of the rebound structure is made of a highly elastic metal material to ensure that the rocker 5 can quickly return to its initial position after the button 3 is released, improving the sensitivity and service life of the switch.

[0032] When the user presses down on button 3, magnet 4 also moves downwards. This causes the magnetic sensor 2 on the PCB board 13 at the bottom of the microswitch to detect the increase in magnetic field strength. Magnetic sensor 2 converts the detected change in magnetic field strength into a voltage change signal, which is transmitted to the mouse controller via PCB board 13, thus recognizing that button 3 has been pressed. When the user releases their hand, the spring force of the contact spring 10 rebounds, causing button 3 and magnet 4 to move upwards. Magnetic sensor 2 then detects the decrease in magnetic field strength. Similarly, magnetic sensor 2 converts the detected change in magnetic field strength into a voltage change signal, which is transmitted to the mouse controller via PCB board 13, allowing the mouse controller to recognize that button 3 has been released.

[0033] Furthermore, since the downward travel of button 3 causes magnet 4 to move downwards as well, the distance between magnet 4 and magnetic sensor 2 gradually decreases. We know that the magnetic field strength around magnet 4 decreases with increasing distance and increases with decreasing distance. This means that the magnetic field strength sensed by magnetic sensor 2 gradually increases as button 3 is pressed downwards. Magnetic sensor 2 can convert this gradually increasing magnetic field strength into a gradually changing voltage signal. Similarly, when button 3 is released, as the spring 10 rebounds, the distance between button 3 and magnetic sensor 2 increases, and magnetic sensor 2 can also convert this into a reverse voltage signal. Based on the monotonic correspondence between button travel and voltage signal, the mouse controller can adjust the trigger travel of button 3 by setting different trigger voltage thresholds, and can even set different values ​​for the trigger travel of pressing button 3 and releasing the microswitch.
