Acrylic membrane switch panels are flexible film panels manufactured from acrylic (plexiglass) material, integrating key functions, indicator components and instrument operating interfaces. Their structure typically comprises four layers: an acrylic panel layer printed with identification symbols, an upper circuit layer with contacts, an isolation layer, and a lower circuit layer. When external pressure is applied to the panel, the upper circuit contacts deform to make electrical contact with the lower circuit plates, establishing a conductive path. Upon release, the film rebounds to break the circuit, triggering the signal. This design combines decorative appeal with functionality, serving as a critical component in the human-machine interface of electronic devices.
1. Excellent weather resistance and acid-alkali tolerance, exhibiting no yellowing or hydrolysis even after prolonged exposure to sunlight and rain.
2. Extended lifespan, lasting over three years longer than products made from other materials.
3. Excellent light transmission exceeding 92%, requiring lower lighting intensity and reducing energy consumption.
4. Exceptional impact resistance, sixteen times stronger than ordinary glass, making it suitable for high-security installations.
5. Superior electrical insulation properties, compatible with all types of electrical equipment.
6. Lightweight construction, half the weight of standard glass, minimising structural and support loads.
7. Vivid colours and high brightness unmatched by other materials.
8. High malleability with extensive design flexibility and ease of processing.
9. High recyclability, aligning with growing environmental awareness.
10. Low maintenance: easily cleaned by rainwater or with soap and a soft cloth.
Durability and reliability: Employing a combination of metal spring contacts and silicone rubber buttons, the operational lifespan exceeds one million cycles, making it suitable for high-frequency usage scenarios (such as access control systems with over 30,000 daily operations). Environmental Adaptability:
IP67-rated protection withstands moisture exposure (e.g., Shenzhen's rainy season at 95% humidity).
Antimicrobial materials achieve 99.2% inhibition of E. coli, suitable for sterile environments like hospitals.
Interaction Enhancements: Translucent illuminated film reduces night-time misoperation rates (e.g., automatic backlighting in night-time access control systems).
Space Optimisation: Ultra-thin construction (thickness <0.3mm) reduces device footprint by 37%, enhancing installation flexibility. Characters remain washable and undamaged, suitable for long-term outdoor applications.
