(1) Durability
The life of a membrane switch keyboard can generally reach more than one million times. The reason for such a long life is that the action of the switch is only realized by the vertical movement of the elastic membrane. Although the elastic film has undergone a million times of creeping, due to the small creep range, only 0.1~0.3mm (that is, the switching stroke), and the rationality of the material selection, it is far from reaching the yield limit of the film, so the film material Can withstand more than one million times of life without deformation. On the other hand, the contacts of the switch are in vertical contact, and the amount of wear is very small; while the screen printed contacts can form a sufficient thickness, and a layer of conductive carbon is printed on the silver paste contacts to achieve high The purpose of wear resistance and self-lubrication, so the life of the membrane switch is dozens of times longer than that of the mechanical contact switch.
(2) Good sealing performance
Because the membrane switch keyboard is an integrally sealed structure, the contacts of the switch are not corroded by harmful gases and are not easily oxidized; it has the characteristics of waterproof and dustproof, which is more suitable for use in various harsh environments.
(3) Small size, light weight and reliable structure
membrane switch keyboard 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 films. The connecting wires and lead wires between all switches are screen printed one-time Completed, the total thickness is 1~3mm, so the volume is reduced, the quality is reduced, and the reliability is improved.
(4) Rich colors and beautiful appearance
membrane switch keyboard can be personalized in the design of the color pattern according to the user's design concept, and the comprehensive characteristics of the beautiful material, the beautiful decoration and the beautiful craftsmanship can be reflected in the decoration effect.
(5) Reduce the cost of supporting mechanical and electrical products
Traditional mechanical switches need to be welded during installation, and even must be fitted with a fixed bracket. The installation of the membrane switch is paste type, 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 into the socket of the rear circuit of the whole machine, and the circuit can be connected in an instant. It saves labor and materials, and reduces the cost of the complete machine.
