Abstract
An illuminated keyboard includes a transparent frame plate, a key, a light source and a membrane switch circuit module. The light beam emitted by the light source is transmissible through the transparent frame plate. Consequently, the light source may be disposed on the membrane switch circuit module, between the key and the transparent frame plate, or under the transparent frame plate.
