  • Patent number: 9734966
    Abstract: A light-emitting keyboard includes a membrane circuit board including a lower layer, an upper layer and a light-guiding spacer layer arranged between lower layer, an upper layer and defining therein a tapered through hole, a substrate holding membrane circuit board, a key assembly including key cap, a linkage coupled between key cap and substrate and an elastic element supported between key cap and membrane circuit board, and a light source for emitting light into the light-guiding spacer layer. The light-guiding spacer layer uses its thickness to isolate the lower layer and the upper layer and its tapered through hole to provide room for a triggering stroke for enabling the upper layer to electrically contact the lower layer second circuit in producing a corresponding switching signal each time the key assembly is pressed. Thus, the light-emitting keyboard achieves the characteristics of low profile, low manufacturing cost, and simple assembly process.
