http://www.sblindia.com - Solar Biotronic Laboratories Illuminated keyboards are specially made for dim light areas. Solar Biotronic Laboratories uses SMD LEDs, EL Layers or Optical fibers to illuminate such keyboards. To enhance Illumination, Solar Biotronic Laboratories uses special raw materials and assembly techniques. Illumination can also be achieved using back lighted mechanical switches.
The specifications for these switch panels are similar to the specifications of Sealed Keyboard Panels (Low Profile Push button Switches). The working of these switches is based on Charge Detector (CD) technology. When any user touches the key / switch area the capacitive charge from the user’s body is detected by a specially developed circuit, and the signal is passed on to the system. The solid state nature of the circuit makes the life of such a switch virtually infinite.
