Flexible printed circuit membrane switches are high-performance electronic components integrating flexible printed circuit (FPC) and membrane switch technology, widely utilised in consumer electronics, medical equipment, industrial control systems, automotive electronics and other fields.
Ultra-miniaturised design: Employing precision etching techniques, circuit line widths can reach 0.05mm with minimum spacing also achieving 0.05mm. This enables complex circuit layouts within extremely compact spaces, meeting demands for high-density, miniaturised products.
High-Sensitivity Operation: Based on capacitive or pressure-sensing principles, it effortlessly detects minute touches or pressure variations, enabling precise control.
Slim Profile and Flexibility: Typically measuring 0.1–0.5mm in thickness, it can be freely bent or folded to conform tightly to confined spaces or irregular surfaces, such as curved handles or the inner surfaces of wearable device straps.
High reliability: Withstands over one million press cycles, featuring robust waterproof and dustproof performance. Achieves IP67 protection rating for stable operation in harsh environments.
High customisation: Switch shape, dimensions, colour, and key layout can be tailored to requirements. Integration of components like LED lights and metal springs accommodates diverse product design specifications.
Consumer Electronics: Widely employed in mobile phones, tablets, remote controls, smartwatches, headphones and similar devices for controlling buttons, touch panels or as flexible connectors. Effectively reduces device thickness while enhancing portability and aesthetic appeal.
Medical Devices: Commonly used in compact medical instruments such as blood glucose monitors, blood pressure monitors and portable ventilators. Its sealed design prevents liquid ingress, facilitates cleaning and sterilisation, and meets hygiene requirements for medical equipment.
Industrial Control: Integrated into compact industrial control panels and handheld testers, providing multiple operational buttons within confined spaces. Exhibits robust vibration and impact resistance, meeting the stringent demands of industrial environments.
Automotive Electronics: Suitable for in-car applications including rear-view mirror adjustment buttons, window control switches, and seat adjustment controls. Its compact dimensions and high reliability optimise interior space allocation and enhance the driving experience.
Smartwatch Buttons: Compact FPC membrane switches can be integrated along the watch face edge or inside the strap, enabling function switching, power cycling and other operations. This design minimises space requirements while ensuring responsive operation and durability.
Home Appliance Remote Controls: For devices such as air conditioners and televisions, compact FPC membrane switches enable slimmer remote designs with optimised button layouts, while enhancing tactile feedback and extending button lifespan.
