Film switches are switches made by printing touch point circuits with conductive paste on various films, representing a type of contact switch. These switches are flat, multi-layered, and have a sealed structure, integrating push-button switches, panel function markings, transparent reading display windows, indicator light apertures, and circuitry into a complete electronic control system.
1. Excellent sealing performance
Film switches, being a fully sealed structure, are resistant to erosion by harmful gases and are not prone to oxidation; they feature waterproof and dustproof capabilities, making them particularly suitable for use in various harsh environments.
Rich in color and aesthetically pleasing
Film switches can reflect personalized design concepts of the user, showcasing a combination of color patterns, material beauty, decorative beauty, and craftsmanship excellence.
3. Compact, lightweight, and structurally reliable
The thin film switch can be arranged and combined into a thin film keyboard, featuring a high density setting. It is composed of a sealed, multi-layer thin film structure. The connection lines and lead-out lines between all switches are printed in one go using screen printing. The total thickness ranges from 1 to 3mm, thereby reducing the volume, weight, and improving reliability.
4. Reduce the matching costs of electromechanical products
Traditional mechanical switches require welding during installation and often need to be paired with a mounting bracket; in contrast, the installation of film switches is adhesive-based. Simply peel off the backing paper, and they can be securely粘贴 to the entire surface of the unit. The wire leads can then be inserted into the unit's rear circuitry's socket, instantly connecting the circuit.
5. Durability
The lifespan of membrane switches typically exceeds one million activations. The longevity is attributed to the switch's operation, which is solely achieved through the vertical bouncing of the elastic film. Despite undergoing one million蠕动 movements, the elastic film's deformation is minimal, merely 0.1 to 0.3mm (the switch's travel distance). Coupled with the rational choice of materials, it has not reached the yield limit of the film, allowing the material to withstand over one million activations without deformation. Furthermore, the switch's contact points are vertically engaged, resulting in minimal wear. The screen-printed contact points are thick enough and, in addition to the silver paste, have an extra layer of conductive carbon, enhancing wear resistance and self-lubrication. Consequently, the lifespan of membrane switches is dozens of times longer than that of mechanical contact point switches.
