The key switch has waterproof key switch and ordinary key switch. I believe that many users have such a question, what is the difference between ordinary key switches and waterproof key switches. How can the key switch be waterproof? Is there anything unique about the waterproof key switch, so it can play a waterproof effect? Yes, indeed, the waterproof key switch has one more component than the ordinary key switch, so it can achieve the waterproof effect.
First of all, in terms of structure, the waterproof key switch has an extra polyimide film than the ordinary key switch, and an extra layer of polyimide film is added on the reed of the key switch. Therefore, the waterproof effect is achieved, because the environment faced by the waterproof key switch is much more complicated than the environment faced by the ordinary key switch. Therefore, there will be more protection measures for the use of materials. The specific application of this waterproof key switch is restricted by many factors, such as: installation method and installation direction of the product, airflow, pressure difference acting on the product, strength of fluid rebound and working voltage; and so on. Even if the Arcolectric waterproof key switch with excellent sealing performance, its sealing technology has reached the leading level, it does not mean that the switch is completely sealed, and it is necessary to prevent the intrusion of corrosive gases or substances.

Waterproof Key Switch

Ordinary key switch and waterproof key switch In terms of performance, the biggest difference between ordinary key switches and waterproof key switches is that the waterproof key switch has one more function, which is waterproof. Ordinary key switches do not have this ability, but the other functions of the two are the same.
The key switch has the advantages of small contact resistance load, accurate operating force error, and diversified specifications. It has been widely used in electronic equipment and white goods, such as audio and video products, digital products, remote controls, communication products, and household appliances. , Security products, toys, computer products, fitness equipment, medical equipment, money detector pens, laser pen buttons and so on. Because of the environmental conditions of the key switch (elastic force with pressure less than 2 times/environmental temperature and humidity conditions and electrical performance), large equipment and high-load buttons are directly replaced by conductive rubber or dome switch hardware shrapnel, such as medical equipment, TV. machine remote control, etc.
