In the internal structure, the structure of the waterproof switch is the same as other switches. The specially designed metal shrapnel can withstand hundreds of thousands of presses, and it can also complete a very excellent button feel; and all the difference is that the waterproof metal tact switch has better touch and air tightness. In addition to the shrapnel, a waterproof silicone film is added. , It can fill the gap inside the push button switch closely to ensure the integrity of the overall external structure.
Because of the need to ensure sufficient waterproof performance, the production process of waterproof metal switches is significantly more messy, requiring 6 processes such as stamping, cleaning, and molding. In addition, because waterproof metal tact switches generally require a waterproof level of IP67 or above, they have strict requirements on the precision of parts processing. Although the technology of the waterproof metal switch is more sophisticated, its price is relatively stable because of the maturity of the market, and it is less affected by the market's raw materials.
