Membrane switches constitute an integrated operating system combining key functions, indicator elements, and instrument panels. They comprise four components: the front panel, upper circuit, isolation layer, and lower circuit. Upon pressing the membrane switch, the upper circuit's contact point deforms downward, making contact with the lower circuit's electrode plate to complete the circuit. When the finger is released, the upper circuit contact point springs back, breaking the circuit and triggering a signal. Membrane switches feature a compact structure, aesthetically pleasing design, and excellent sealing properties. They offer moisture resistance and extended service life. These switches find widespread application across electronic communications, electronic measurement instruments, industrial control systems, medical equipment, the automotive industry, smart toys, and household appliances.
Hongmao specialises in customising various membrane switch panels, including dome switch keypads, FPC membrane switches, and circuit-integrated membrane switches.
Window-integrated industrial membrane switches are human-machine interface components that combine transparent viewing areas with control functions. Designed specifically for industrial environments, they offer high reliability, resistance to harsh conditions, and customisable features.
Industrial Automation: Control panels for CNC machine tools and PLC control cabinets, featuring vibration resistance (10–2000 Hz, 10g acceleration) and electromagnetic interference shielding.
Medical Equipment: Control interfaces for patient monitors and surgical instruments, compliant with ISO 13485 standards, withstanding high-temperature autoclaving (134°C) and alcohol wiping.
Smart Home Appliances: Touch panels for ovens and washing machines, featuring IP67 waterproof rating to withstand kitchen moisture and fingerprint-resistant coating for easy cleaning.
Outdoor Equipment: Agricultural machinery and traffic signal control boxes, passing UV ageing tests (1500 hours with no significant fading) and salt spray tests (48 hours with no corrosion).
