Acrylic membrane switches are flexible circuit control panels manufactured from polymethyl methacrylate (PMMA, commonly known as acrylic) material. Combining functionality with aesthetic appeal, they find extensive application across electronic communications, electronic measurement instruments, industrial control systems, medical equipment, the automotive industry, smart toys, and household appliances.
Sealing and Protection Performance
Featuring a fully sealed structural design, it offers dustproof, waterproof, and oil-resistant capabilities. This effectively isolates external contaminants from affecting internal circuitry, making it suitable for medical environments involving frequent exposure to chemical agents such as disinfectants and alcohol.
Reliability
Operating voltage typically ≤50VDC, with a temperature range of -20°C to +70°C. Service life exceeds 5 million cycles, ensuring stable operation of medical equipment.
Safety
Materials comply with medical industry safety standards, offering excellent insulation to prevent leakage risks. Meets high-temperature sterilisation requirements (e.g., stability at 70°C).
Customisation Capabilities
Supports bespoke keypad layouts and graphics tailored to instrument interface requirements, unifying functionality with aesthetics to meet specialised operational demands of medical equipment. Hongmao customises various membrane switch panels, dome switch keypads, FPC membrane switches, and circuit membrane switches.
