[0002] A mechanical keyboard usually includes a conductive plate and a plurality of keys arranged on the conductive plate. Each key includes a mechanical switch shaft and a keycap arranged on the mechanical switch shaft. The closing of the mechanical switch shaft is controlled by pressing the keycap, so that the mechanical segment feel of the key is stronger, thereby improving the user's pressing feel.

[0003] However, for competitive players, they need both the feel of mechanical switches and the function of magnetic axis keys. However, the switches of existing keyboards are either magnetic axes or key axes, which are subject to certain limitations and cannot have the two-in-one functions of magnetic axes and mechanical axes at the same time to provide users with greater freedom of choice. At the same time, during the pressing process of existing keys, due to tolerances in the manufacturing process, the axis core line of the key pressing will be displaced, resulting in a reduction in the service life of the key. Therefore, the applicant has made a useful design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] Reference example Figures 1 to 4A shaft switch combining a magnetic shaft and a mechanical shaft, comprising a shaft seat 1, a shaft cover 2 covering the shaft seat 1, and a key 3 slidably arranged on the shaft seat 1 and the shaft cover 2, guide grooves 4 are arranged on both sides of the shaft seat 1 and the shaft cover 2, the key 3 is provided with a magnetic shaft core 31, balls 8 are arranged on both sides of the key 3 and abut against the guide grooves 4, the shaft seat 1 is evenly distributed with a plurality of balls 8 with a dot as the axis center, and abut against the outer wall of the magnetic shaft core 31 when pressed down, a dynamic and static component 5 is arranged in the shaft seat 1, and when downward pressure is applied to the key 3, the key 3 abuts against the dynamic and static components 5, which is used to trigger the signal. When the button 3 is not in the trigger state, the magnetic axis core 31 maintains a certain distance from the Hall sensor on the circuit board. The Hall sensor senses the change of the magnetic flux of the magnetic axis button 3. When downward pressure is applied to the button 3, the distance between the magnetic axis core 31 and the Hall sensor on the circuit board is reduced, so that the potential difference in the Hall sensor increases as the magnetic axis core 31 approaches. When the potential difference reaches the threshold of the Hall sensor, the Hall sensor is triggered, and then the signal is triggered.

[0026] It is worth mentioning that the button 3 is provided with a guide portion 33 on both sides, the guide portion 33 is provided with a first groove 331, the button 3 is provided with a contact portion 32, the guide portion 33 is used in conjunction with the guide groove 4, the first groove 331 accommodates the ball 8, and the contact portion 32 is used to separate the moving contact 515 from the static contact 521;

[0027] It is worth mentioning that a blind hole 11 is provided at the bottom of the shaft seat 1, and a plurality of second grooves 12 are evenly distributed on the top of the blind hole 11 with a dot as the magnetic shaft core 31, and the blind hole 11 allows the magnetic shaft core 31 to enter therein so that the Hall sensor on the circuit board can sense it, and the second groove 12 is convenient for accommodating the ball 8;

[0028] It is worth mentioning that the ball 8 is arranged in the first groove 331 and the second groove 12, and the ball 8 provides guidance for the key 3 when it is pressed down and reduces the friction between the key 3 and the shaft seat 1 and the shaft cover 2, thereby reducing the deviation between the axis center line of the key 3 and the axis center line of the shaft cover 2 and the shaft seat 1 when the key 3 is pressed down, thereby ensuring that the pressing down of the key 3 causes the moving contact 515 to stably separate from the static contact 521;

[0029] It is worth mentioning that a cap 6 is fixedly arranged above the blind hole 11, and the cap 6 is provided with a hollow column 61. The cap 6 is provided with a third groove 62 corresponding to the second groove 12. A spring 7 is provided on the outer wall of the hollow column 61, and abuts against the key 3, so that the key 3 protrudes from the shaft cover 2. The balls 8 on both sides of the guide part 33 abut against the guide groove 4, providing a first guiding effect for the up and down movement of the key 3. The hollow column 61 provides a second guiding effect for the magnetic shaft core 31. The balls 8 in the second groove 12 abut against the magnetic shaft core 31 to provide a third guiding effect for the key 3. By providing multiple guides for the key 3, the axial deviation between the magnetic shaft core 31 and the hollow column 61 and the blind hole 11 is reduced. The cap 6 prevents the balls 8 in the second groove 12 from escaping, and the spring 7 resets the key 3 after being pressed down.

[0030] It is worth mentioning that the dynamic and static assembly 5 includes a dynamic spring piece 51 and a static spring piece 52. The static spring piece 52 is provided with a static contact 521. The dynamic spring piece 51 is provided with a first bent portion 511. The first bent portion 511 is extended with a second bent portion 512. Both sides of the second bent portion 512 are provided with extension portions 513. The extension portion 513 is provided with a third bent portion 514 and is located on the active track of the abutment portion 32. The second bent portion 512 is provided with a dynamic contact 515 and abuts against the static contact 521. When the dynamic spring piece 51 is inserted into the groove of the shaft seat 1, the first bent portion 511 is subjected to the top force of the side wall of the shaft seat 1, so that the first bent portion 511 moves a distance toward the static point, so that the first bent portion 511 stores energy, and at the same time, the distance between it and the first bent portion 511 is reduced. Thereby, the moving point is close to the static point, and the contact resistance between the two is reduced. When the key 3 is pressed down, the contact part 32 pushes the third bending part 514. When the contact part 32 is located at the highest bending point of the third bending part 514, the second bending part 512 is pushed to move in the direction of the first bending part 511, so that the moving contact 515 separates from the static contact 521, and the second bending part 512 stores energy. The circuit on the circuit board is separated by the moving contact 515 and the static contact 521, so that the circuit board is short-circuited to trigger the signal. The change in resistance generated by the contact between the contact part 32 and the third bending part 514 will have an obvious triggering feeling, which will affect the feel of the mechanical key 3. This product has the functions of a magnetic axis key 3 and a mechanical axis key 3, and can be adapted to different keyboards and meet user needs.

[0031] The above design scheme can make the product achieve the advantages of good stability, long service life and good adaptability.

It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
