Smaller button designs can provide more occasions and changes, such as the use of hiding buttons in electronic products. The button design can be called a push switch (or a micro switch). The push switch is a contact mechanism that has a small contact interval and a snap-action mechanism, and uses a specified stroke and a specified force to switch action. It is covered by a shell. A switch with a drive rod outside, and the push switch can be applied to various electronic products, such as air-conditioning switches, microwave ovens, small electric cookers, communication equipment, water heaters and other electrical products that can generate ON/OFF electronic signals through a small mechanical switch structure , And can be hidden in these products through the miniaturized push switch, so as to enhance the beauty of the product.

The structural design of the push switch is roughly that there is an accommodating space in a seat, and a plurality of terminals can be accommodated in the accommodating space, and a conductive elastic piece under the pressing part is pushed through a pressing part to contact the plural contacts on the terminals Part, to make these terminals have electrical connections to switch the ON/OFF state of electronic products, and the above push switch design does not include Dust-proof and waterproof design, so that in a humid environment or a room with a lot of dust, the push switch may be short-circuited or poor contact, and it does not have the design of noise reduction function. When the switch is pressed again Excessive noise is produced, which is inconvenient to use in situations requiring quietness, and if the user who presses the switch does not produce a good pressing feel when pressing, he will often apply more force and then press the switch, which will reduce the pressure of the switch in the long run. The service life, and how to avoid the aforementioned problems, needs to be solved by those engaged in this industry.

Therefore, in view of the above-mentioned problems and deficiencies, the creators collected relevant information, and through multiple evaluations and considerations, they began to design the creation of this kind of push switch structure.
