Abstract: A keyboard with lighting source provides two conductive sheets made of copper foil, tin foil or aluminum foil as electrodes of semiconductor light emitting components. Multiple through holes are provided at the upper conductive sheet electrode. The semiconductor light emitting components are attached to and connected to the lower conductive sheet electrode at the areas exposing from the through holes and the upper conductive sheet electrode at the areas near the through holes. No light guide plate or printed circuit board with complicated layout is necessary to meet the required features such as thinness, uniform luminance, and simplicities of structure and fabricating process.

Abstract: A membrane switch including a first film, a second film and an insulating layer is provided. The first film has a first circuit, a first outlet cable and a second outlet cable. The first circuit is electrically connected with the first outlet cable, and the second outlet cable is disposed adjacent to the first outlet cable. A single outlet joint is formed from the first and second outlet cables. The second film has a second circuit and an outlet terminal, wherein the outlet terminal is electrically connected to the second circuit. The insulating layer is disposed between the first film and the second film so that the first film and the second film are electrically insulated. The outlet terminal is electrically connected to the second outlet cable. The membrane switch is economical and meets the needs of customers.
