Description

Technical Field

[0001] This utility model relates to the field of metal spring switch technology, and more specifically to a double-layer metal spring switch assembly. Background Technology

[0002] Dome switches, typically made of stainless steel, are an important component of any switch system. They function as a switch between the operator and the product through their conductivity, and their stable rebound force allows them to automatically return to their original position after being pressed, providing excellent tactile feedback. However, current dome switches on the market are single-layer dome switches, resulting in a weaker tactile feel. For switches requiring a stronger tactile feedback (such as game control switches), the traditional dome switch's rebound performance is insufficient. Therefore, there is a need for a spring switch with both good rebound and a superior tactile feel. This invention provides a double-layer metal spring switch assembly to solve these problems. Utility Model Content

[0003] To solve the problems mentioned in the background art, the technical solution adopted by this utility model is: a double-layer metal spring switch assembly, which includes a first PET film, a second PET film, a first dome switch and a second dome switch, wherein the first dome switch is bonded between the first PET film and the second PET film, and the second dome switch is bonded to the bottom of the second PET film, so that the first dome switch and the second dome switch are bonded into an integral double-layer structure.

[0004] As a preferred technical solution of this utility model, the first PET film is provided with a first exhaust port and a second exhaust port symmetrically opened on both sides of the first dome piece, and the second PET film is provided with a third exhaust port and a fourth exhaust port symmetrically opened on both sides of the second dome piece.

[0006] As a preferred embodiment of the present invention, a first pot-shaped PET film is disposed between the first exhaust port and the second exhaust port, and a second pot-shaped PET film is disposed between the third exhaust port and the fourth exhaust port.

[0007] As a preferred embodiment of this utility model, the first PET film is bonded to the middle of its bottom end by a first pot-shaped PET film, and the second PET film is bonded to the middle of its bottom end by a second pot-shaped PET film.

In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figures 1-5 This utility model relates to a double-layer metal spring switch assembly, comprising: a first PET film 1, a second PET film 2, a first dome switch 3 bonded to the middle of the first PET film 1 and the second PET film 2, and a second dome switch 4 bonded to the middle of the bottom end of the second PET film 2, so that the first dome switch 3 and the second dome switch 4 are bonded together as an integral double-layer structure. The first PET film 1 has a first vent 7 and a second vent 8 symmetrically opened on both sides of the first dome switch 3, and the second PET film 2 has a third vent 9 and a fourth vent 10 symmetrically opened on both sides of the second dome switch 4. The first dome switch 3 and the second dome switch 4 are both made of stainless steel, and the first PET film 1 and the second PET film 2 are both made of silicone or a material with equivalent connecting and rebound properties.

[0021] Among them, the first exhaust port 7, the second exhaust port 8, the third exhaust port 9, and the fourth exhaust port 10 are all fan-shaped structures. The first exhaust port 7 corresponds to the third exhaust port 9, and the second exhaust port 8 corresponds to the fourth exhaust port 10. A first pot-shaped PET film 5 is disposed between the first exhaust port 7 and the second exhaust port 8. A second pot-shaped PET film 6 is disposed between the third exhaust port 9 and the fourth exhaust port 10. The bottom center of the first PET film 1 passes through the first pot-shaped PET film 5. The first dome film 3 is bonded together with the second PET film 2. The second dome film 4 is bonded to the bottom center of the second dome film 5 via the second dome film 6. The first dome film 5 and the second dome film 6 are the same size and structure. Both the first dome film 5 and the second dome film 6 have annular edges 11 on their outer circumferences. The first PET film 1 and the second PET film 2 are the same size and shape. The first dome film 3 and the second dome film 4 are the same size and shape. The first dome film 3 and the second dome film 4 have annular flared openings 12 on their outer circumferences. The outer diameter of the annular edge 11 is smaller than the outer diameter of the annular flared opening 12. The annular edge 11 ensures that the elastic recovery deformation performance of the first dome film 5 and the second dome film 6 is enhanced. Similarly, the annular flared opening 12 enhances the elasticity performance of the first dome film 5 and the second dome film 6.

[0022] Specifically, the first PET film 1 and the second PET film 2 are bonded together to form a double-layer overlap between the first PET film 3 and the second PET film 4, thereby enhancing the rebound performance, increasing the pressing pressure, and improving the feel. The first PET film 3 and the second PET film 4 are designed independently, so as not to affect the rebound effect of a single PET film. The pot-shaped design of the first pot-shaped PET film 5 and the second pot-shaped PET film 6 can further enhance the rebound when pressed. The first vent 7, the second vent 8, the third vent 9, and the fourth vent 10 opened on the first PET film 1 and the second PET film 2 facilitate the expulsion of air when pressing the first PET film 3 and the second PET film 4.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
