於圖1C的實施例中，光源150係設置於下電路層146的上表面，即銅導通點146a、146b與銅導線146c、146d所在的表面，但不以此為限。如圖1D所示，於一變化例中，光源150可設置於下電路層146背向間隔層144之一側。舉例而言，光源150可為反向式發光二極體(reversed LED)，且下電路層146可為雙面線路層，即下電路層146的上表面具有開關電路(例如銅導通點146a、146b與銅導線146c、146d)，而下電路層146的下表面具有光源電路(例如銅導線152a、152b)。藉此，光源150可藉由銅導線152a、152b電連接於下電路層146背向間隔層144之一側，並穿過下電路層146之孔洞146e、間隔層144之第二孔洞144b及上電路層142的第三孔洞142b，而朝鍵帽110提供光線。在此需注意，圖1D雖以反向式發光二極體作為光源150之實施例，但光源150亦可為側發光式的發光二極體。如圖1E所示，於另一變化例中，光源150係設置於下電路層146的下表面且並以銅導線構成的光源電路152連接，且導光膜片148可對應光源150設置，以使得光線沿導光膜片148傳遞再導向鍵帽110的透光區116。具體而言，導光膜片148對應光源150的位置可開設有光源孔148a。當光源150設置於下電路層146的下表面時，光源150係位於光源孔148a中，且光線沿導光膜片148傳遞，以導向鍵帽110的透光區116。於此實施例，導光膜片148亦可為PET膜片或任何合宜的聚合物膜片。 In the embodiment of FIG. 1C, the light source 150 is disposed on the upper surface of the lower circuit layer 146, that is, the surface where the copper conductive points 146a, 146b and the copper wires 146c, 146d are located, but is not limited thereto. As shown in FIG. 1D, in a variant, the light source 150 can be disposed on one side of the lower circuit layer 146 facing away from the spacer layer 144. For example, the light source 150 can be a reversed-emitting diode, and the lower circuit layer 146 can be a double-sided circuit layer, that is, the upper surface of the lower circuit layer 146 has a switching circuit (eg, a copper conduction point 146a, 146b and copper wires 146c, 146d), and the lower surface of the lower circuit layer 146 has light source circuits (e.g., copper wires 152a, 152b). Thereby, the light source 150 can be electrically connected to one side of the lower circuit layer 146 facing away from the spacer layer 144 by the copper wires 152a, 152b, and through the hole 146e of the lower circuit layer 146, the second hole 144b of the spacer layer 144, and the upper portion The third hole 142b of the circuit layer 142 provides light to the keycap 110. It should be noted that although FIG. 1D uses an inverted light-emitting diode as the light source 150, the light source 150 can also be a side-emitting light-emitting diode.

In addition, since the resistance value of copper is very low, the uniformity of illumination of the plurality of light sources 150 is not affected by the plurality of light source circuits 152 of different lengths on the illuminated keyboard.
