Membrane switch is a kind of anti environment switch, anti environment is able to resist harsh external environment, such as dust, temperature and moisture. Water is lethal to commodities, especially electronic commodities. This kind of lethality is like dropping water wears away stones. If it can't block the harm brought by water, it can reduce the impact of water on the longevity of commodities.

　　Membrane switch is not afraid of water, that is, it can reduce the impact of water on switch life to a certain extent. Facing strong water, the survival factors of the switch are related to its structure, manufacturing data and manufacturing properties. The membrane key switch belongs to a sealed structure, which can prevent the invasion of foreign impurities to a certain extent. The switch manufacturing materials are waterproof materials and guaranteed brand materials, so it can maintain the original life when contacting with a small amount of moisture. As for the manufacturing nature of the switch, it is to change the traditional switch and make the existing switch play a greater role in the whole machine goods. As for the membrane switch, it has many functions different from the ordinary switch, and it can also be used as the appearance of the whole machine goods to protect the whole machine goods from external danger.

　　The service life of membrane switch can be as high as 1 million times, so there is no need to worry too much about the harm caused by external influence. Waterproof is only one of the main functions of membrane switch.
