This specification describes a dedicated membrane switch/control panel for nurse call systems. It utilizes antimicrobialsurface materials and precision circuit technology, designed specifically for high-frequency-use medical environmentsrequiring easy cleaning and disinfection. It offers stable, long-lasting tactile feedback and visual guidance.
1 Materials & Construction
Front Layer
Antimicrobial polyester film (with antibacterial coating, resistant to common disinfectants such as alcohol andisopropyl alcohol).
Or Medical-grade silicone (waterproof, slip-resistant, easy to clean, customizable soft-touch feel).
Circuit Layer
Flexible Printed Circuit (FPC) with high-precision silver or copper foil traces.
Optional Light Guide Film (LGF) backlighting for uniform, low-power illumination, supporting multi-color LEDindicators.
Key Mechanism
Metal dome (tactile, crisp feel, lifespan of 200k to 1 million cycles, customizable per client requirements).
Silicone rubber keypad (quiet operation, soft tactile feel, can integrate backlighting).
Adhesive Layer
Medical-grade pressure-sensitive adhesive ensures long-term bonding without residue.
