1. Durability
The service life of pet protective film can generally reach more than one million times. The reason for such a long service life is that the action of the switch is only realized by the vertical bouncing of the elastic film. Although the elastic film has undergone millions of times of creep, due to the small Creep Range, which is only 0.1 ~ 0.3mm (i.e. switching stroke), and the rationality of material selection, it is far from reaching the yield limit of the film. Therefore, the film material can withstand more than one million times of life without deformation
On the other hand, the contact of the switch is vertical contact, and the wear is very small; The screen printed contact can form sufficient thickness, and a layer of conductive carbon is printed on the silver paste contact to achieve the purpose of high wear resistance and self lubrication. Therefore, the service life of pet protective film is more than ten times higher than that of mechanical contact switch
2. Good sealing performance
Because the pet protective film is an integral sealing structure, the contact of the switch is not eroded by harmful gases and is not easy to oxidize; It has the characteristics of waterproof and dustproof, so it is more suitable for various harsh environments
3. Small size, light weight and reliable structure
The pet protective film can be arranged and combined into a film keyboard in design. Its setting density is large, and it is a sealed sheet structure composed of multi-layer films. The connecting lines and outgoing lines between all switches are completed at one time by screen printing, with a total thickness of 1 ~ 3mm. Therefore, the volume is reduced, the quality is reduced and the reliability is improved
4. Rich colors and beautiful appearance
Pet protective film can embody personalization in the design of color patterns and the comprehensive characteristics of material beauty, decoration beauty and process beauty in the decorative effect according to the user's design idea
5. Reduce the supporting cost of mechanical and electrical products
