Introduction to the overall performance of the membrane switch

1. Durability: The service life of the membrane switch 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 direction of the elastic membrane. Although the elastic film has undergone millions of peristalsis, the creep amplitude is very small, only 0.1~0.3mm (the switch stroke), and the material selection is reasonable, which is far from reaching the yield limit of the film, thus the film material can withstand a life of more than one million times without deformation.


2, good sealing performance: because the membrane switch is the overall sealing structure, the contact of the switch is not corroded 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, rich colors and beautiful appearance: membrane switch can be based on the user's design concept, in the design of the color pattern to reflect the personalized, in the decorative effect reflects the beauty of the material, decorative beauty, craft beauty of the comprehensive characteristics.


4. Reduce the matching of mechanical and electrical products

Cost: The traditional mechanical switch needs to be welded during installation, and even needs to be matched with a fixed bracket; while the installation of the membrane switch is pasted, as long as the adhesive paper is removed, it can be firmly pasted on the surface of the whole machine, and its lead outlet is inserted On the socket of the rear circuit of the whole machine, the circuit can be connected instantly.


5. Small size, light weight and reliable structure: The membrane switches can be arranged and combined into a membrane keyboard in design, and its setting density is high, and it is a sealed sheet structure composed of multiple layers of membrane. The connection line and the lead wire between all switches are completed by screen printing at one time, with a total thickness of 1~3mm, thus reducing the volume, reducing the quality and improving the reliability.
