Integral LED
The backlighting of membranes switches or graphic overlays can create a dramatic visual effect especially in low-light environments. So it¡¯s more and more popular used in the switch field.
Tortai can offer you a variety of backlighting solutions to fit your unique requirements.Our engineers will work with you to assist in designing an integrated backlighting solution to fit your requirements for cost, light uniformity, intensity, environmental requirements, and operating life.
Embossed Type
This construction provides for a 180¡ã view angle because the LED sits inside an embossed window. This also allows for a thinner construction.
 
Flat Overlay
This construction provides for a flat LED window. Filler is required to make up the height of the LED and this leads to a thicker construction.
