[0025] like Figures 1-6 As shown, this utility model discloses a switch with adjustable and volume-reducing structure, including a base 1 and a button 2 that is sleeved on the base 1 and can move up and down. A return spring 3 is connected between the button 2 and the base 1. The button 2 is a split structure, including an upper button 21 and a lower button 22 connected together. The outer periphery of the upper button 21 is provided with a wall 211, and the outer plane of the wall 211 is slidably sleeved with the window on the top of the base 1. The lower button 22 is placed in the wall 211 of the lower button 22. The middle part of the lower button 22 is provided with a guide post 221 that extends downward, and the guide post 221 is slidably sleeved with the guide groove 11 inside the base 1.

[0026] Both the guide post 221 and the base 1 of the lower button 22 are molded from plastic. The bottom of the guide post 221 of the lower button 22 collides with the middle contact point of the base 1, achieving plastic-to-plastic collision contact and reducing impact noise. The materials of both can be changed to adjust the button sound effect to the user's needs. For example, the upper button 21 can be made of POM material, while the lower button 22 (where the guide post 221 is integrally molded with the overall structure of the lower button 22, meaning the guide post 221 and the overall structure of the lower button 22 are made of the same material) and the base 1 can be made of PA / POM / PC or other materials.

[0027] The inside of the guide post 221 is a sensor mounting groove, and the bottom of the sensor mounting groove is a closed structure. The sensor 4 is embedded in the inner bottom of the sensor mounting groove. The sensor 4 can be a magnet or a metal rod. When the sensor 4 is a magnet, the switch is turned on and off by the magnet and the Hall sensor. When the sensor 4 is a metal rod, the switch is turned on and off by the metal rod and the inductor.

[0028] The bottom of the middle horizontal plate of the upper button 21 is provided with a positioning post 212, which extends into the guide post 221 and abuts against the top of the sensor 4. The purpose of this design is to prevent the sensor 4 from becoming loose and affecting the conduction performance when the button 2 is pressed.

[0029] The outer surface of the enclosure 211 of the upper button 21 is provided with an elastic part 213 and a stepped part 214 formed by a groove. The elastic part 213 is set higher than the stepped part 214. The inner side of the cavity of the base 1 is provided with a limiting platform 12 for abutting against the elastic part 213 and the stepped part 214 to prevent the button 2 from popping out of the base 1. The elastic part 213 is formed by grooves on both sides and a hollowed-out groove on the back. Therefore, the elastic part 213 can provide sufficient soft contact. When the button 2 rebounds, the elastic part 213 hits the limiting platform 12 of the base 1. The elastic part 213 is subjected to a downward force and a force that pulls the button 2 inward, which plays an effective role in buffering and noise reduction. The step part 214 is used to prevent the button 2 from popping out of the base 1, especially when the user pulls out the keycap, and has sufficient positioning ability. In addition, the elastic part 213 and the stepped part 214 can be provided on the same outer surface of the enclosure 211 of the button 2, or they can be provided on different outer surfaces of the enclosure 211.

[0030] The upper button 21 and the lower button 22 can be connected together by riveting or by a snap-fit ​​structure.

[0031] like Figure 4 As shown, when the upper button 21 and the lower button 22 are connected by riveting, the upper button 21 has multiple rivet posts 215 on its middle horizontal plate, and the lower button 22 has riveting holes 222 corresponding to each rivet post 215. At this time, the riveting point is below the middle horizontal plate of the upper button 21.

[0032] like Figure 5 As shown, when the upper button 21 and the lower button 22 are connected by riveting, the upper button 21 has multiple riveting holes 216 on its middle horizontal plate, and the lower button 22 has rivet posts 223 that mate with each riveting hole. At this time, the riveting point is above the middle horizontal plate of the upper button 21.

[0033] like Figure 6 As shown, when the upper button 21 and the lower button 22 are connected by a snap-fit ​​structure, the side of the middle horizontal plate of the upper button 21 is provided with a buckle 217, and the side of the lower button 22 is snapped into the buckle 217. This structure facilitates the assembly and disassembly of the upper button 21 and the lower button 22.

[0034] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
