Abstract
An ultra-thin computer input device includes a substrate carrying a circuit layout having sets of comb-like contact portions arranged in a staggered manner, and an outer membrane arranged on the substrate and provided with conducting portions corresponding to the comb-like contact portions of the circuit layout of the substrate and electrically insulative beads located on a part of the bottom side of each conducting portion and stopped against the comb-like contact portions of the circuit layout of the substrate. Because the invention eliminates the use of metal domes, rubber domes or scissor-type linking elements, the thickness and number of component parts of the ultra-thin computer input device can be greatly reduced.
