Their basic parameters are similar, they are structurally different only in the thickness of PU, it can be from 4 to 12 mm. Keyboards are backlit through the transparent light guide installed between the printed circuit board and the face layer of the PU. Light sources are economical and durable LED elements. The color of the glow can be very different due to the use of the corresponding LEDs and different colors of the illuminated zones. Keyboards with night lights are widely used in automobile engineering, aviation, as well as on other vehicles and special equipment.
