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.

Abstract: A wireless keyboard includes a keyboard body carrying a set of operating key switches, an elongated spacer block hinged to the front side of the keyboard body and turnable between a first position where the elongated spacer block is kept at the front side of the keyboard body in a substantially flush manner and a second position where the elongated spacer block is attached to a bottom side of the keyboard body for supporting the keyboard body on a flat surface in a tilted condition, a circuit module consisting of a circuit board, a battery power supply, a wireless module and a solenoid switch, and a magnetic member for acting with the solenoid switch to switch off the battery power supply when the elongated spacer block is in the first position or to switch on the battery power supply when the elongated spacer block is in the second position.
