As a leading membrane keypad supplier, HONGMAO integrates advanced materials like UV-stabilized PET and polycarbonate to create keypads resistant to chemicals, extreme temperatures (-30°C to +70°C), and UV exposure. Our keypads support backlighting options (LED/EL), ESD shielding, and multi-language legends, ideal for IoT control panels and laboratory equipment.
HONGMAO membrane keypads offer 50% cost savings over mechanical switches without sacrificing performance. Slim profiles (2.5mm thickness) suit handheld devices, while multi-layer EMI shielding ensures signal integrity. Explore spill-proof designs with 12-month replacement guarantees.
HONGMAO’s LED-integrated keypads deliver uniform illumination (5-100cd/m² adjustable) with <0.3mm light leakage. Choose RGB, monochrome, or electroluminescent options. Our optical bonding technique prevents delamination, perfect for low-light marine or lab environments.
Industrial automation demands reliability. HONGMAO’s membrane keypads employ military-grade polyester overlays with chemical-resistant coatings, ensuring functionality in oil, dust, and moisture-heavy settings. Our patented dome-switch technology guarantees 10M+ press cycles, while UV-cured printing prevents legend fading. Trust HONGMAO’s IEC 60529-certified designs to reduce downtime by 35% versus mechanical alternatives.
Every HONGMAO keypad undergoes 20+ tests, including 500-hour salt spray, 10,000-cycle abrasion, and 85°C/85% humidity exposure. Our automated optical inspection (AOI) system detects defects at 0.1mm resolution, ensuring <0.01% failure rates.
