Abstract
A luminous keyboard includes plural keys, a membrane switch circuit board and a light-emitting element. The membrane switch circuit board includes an upper wiring plate, a lower wiring plate, a conductor line pattern, a separation layer and an etched line pattern. The lower wiring plate includes a wiring plate opening. The conductor line pattern is arranged between the upper wiring plate and the lower wiring plate. The etched line pattern is arranged between the separation layer and the lower wiring plate. The etched line pattern is exposed through the wiring plate opening. The light-emitting element is electrically connected with the etched line pattern through the wiring plate opening in order to acquire electric power. Consequently, it is not necessary to install the illumination circuit board to provide the electric power to the light-emitting element.
