Product Description
LGF Backlight Embossing Membrane Switch with 3M468 Adhesive
Backlit Membrane Switch Technology
Designed for low-light and dark working environments, our illuminated membrane switches feature advanced backlighting technology using Light Guide Film (LGF) with 3M 468 adhesive for secure mounting. LGF technology provides superior performance compared to traditional EL film, offering lower power loss and extended operational life.
LGF Technology Advantages
- Consistent backlighting across any shape or area
- Uniform lighting across multiple switch areas
- Minimal impact on button tactility
- Ideal for compact and thin devices
- Customizable lighting colors with different LED options
