Circuit membrane switches are a novel electronic component integrating key functions, indicator elements, and instrument panels, serving as the core interface connecting device circuits with user operations.
Flexible circuit keypads utilise flexible printed circuits (such as FPC or PCB) as their core component, exhibiting the following key features:
Flexible Circuit Design
Employing FPC or PET flexible materials as the circuit layer enables adaptation to any curved surface with exceptional bending performance.
High Reliability
Switch lifespan exceeding 5 million actuations (via conductive coating processes or metal spring structures)
Wide Operating Temperature Range (-20°C to +70°C)
Waterproof and Dustproof
Excellent sealing properties offering resistance to moisture, oil, and corrosive gases
Lightweight and Compact
Weighs only one-third to one-half of traditional switches with a more streamlined form factor.
Suitable for industrial control, medical equipment, electronic instruments, and similar scenarios, supporting washable panel designs.
Membrane switches, with their waterproof, lightweight and highly customisable characteristics, have found widespread application across multiple core sectors including consumer electronics, industrial control systems, medical equipment and automotive electronics.
Household appliances: Control panels for microwave ovens, rice cookers, washing machines, and air conditioners, enabling function selection and mode adjustment.
Small digital devices: Side buttons (volume, power) on smartphones, buttons on Bluetooth speakers, touch panels on fitness trackers.
Smart devices: Password input panels for smart door locks, operation buttons on robotic vacuum cleaners, dimming controls on smart desk lamps.
Automation Equipment: Operating panels for CNC machine tools and PLC control cabinets, used for parameter setting and start/stop control.
Testing Instruments: Function keys on digital multimeters, oscilloscopes, and water quality analysers, enabling data switching and measurement control.
Industrial terminals: Trigger buttons on logistics barcode scanners; operation panels on production line inspection terminals.
Vehicle control panels: Control buttons for in-car air conditioning, audio systems, and window operation; touch panels on central consoles for certain vehicle models.
Auxiliary equipment: Function keys on dashcams; display operation panels on tyre pressure monitoring systems.
New Energy Vehicles: Charging station operation interfaces, vehicle charging gun activation buttons.
Medical Devices: Programme selection and speed adjustment buttons for fitness equipment (e.g., treadmills, exercise bikes).
Aerospace: Operational panels for certain small onboard devices, requiring lightweight construction and anti-interference capabilities.
