Illuminated Keyboards
Solar Biotronic Laboratories offer Illuminated Keyboards are specially made for dim light areas. They use SMD LEDs, EL layers or optical fibers to illuminate such keyboards. To enhance illumination, solar biotronic laboratories use special raw materials and assembly techniques. Illumination can also be achieved using back lighted mechanical switches.
