Weather resistance and durability: Acrylic material exhibits outstanding weather resistance, withstanding sun exposure and rain without yellowing or hydrolysis, boasting a service life exceeding three years. The membrane switch structure employs a sealed design, with vertical contact points reducing wear and tear to further extend operational longevity.
Lightweight and Portable: Acrylic material weighs only 50% of ordinary glass. Combined with the ultra-thin design of the membrane switch (weighing merely grams to tens of grams), the overall structure is lighter, facilitating portability and installation.
Waterproof and Dustproof: The membrane switch employs an integrated sealed structure, effectively isolating moisture and dust for suitability across diverse environments. Acrylic material inherently possesses moisture-resistant properties, further enhancing the protection rating.
Light Transmission and Energy Efficiency: Acrylic achieves over 92% light transmission, enabling reduced energy consumption when paired with lighting designs. Surface patterns on membrane switches can be rendered with high-precision display effects via screen printing, combining decorative appeal with practical functionality.
Processing and Maintenance Convenience: Acrylic supports cutting, thermal bending, and other fabrication methods, accommodating complex design shapes. Surface stains can be cleaned with soapy water or rainwater, ensuring low maintenance costs.
Waterproof and dustproof
Features a polycarbonate (PC) or polyester (PET) panel with excellent sealing properties, effectively preventing moisture and dust ingress.
Corrosion-Resistant and Durable
Materials exhibit strong corrosion resistance, operating stably within a temperature range of -20°C to +70°C, with a service life exceeding 5 million cycles.
User-Friendly Operation
Flat-panel design minimises accidental activation. Metal spring-loaded structure provides consistent tactile feedback with extended press endurance (over 5 million cycles).
Aesthetically Pleasing and Compact
Panels support full-colour printing to match home appliance aesthetics. Lightweight and space-saving design optimises installation efficiency.
