Abstract: A low profile switch assembly is provided having a base portion that supports a folded flexible circuit sealed about its edges, an overlying deformable elastomeric portion, and a pair of window knobs. The base portion has a pair of integrally formed, upwardly extending posts that pivotally support the window knobs and encourage alignment of the flexible circuit and the overlying elastomeric pad. A series of domes are formed in the elastomeric pad, pairs of which are operated sequentially by the window knob acting on a lever bridging the pairs of domes. The domes, when collapsed, compress portions of the flexible circuit to bridge opposing traces within the folded circuit to actuate respective switches. The arrangement of the components provides a low profile device that inhibits contamination and uses fewer parts.

Abstract: Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A key sheet has a base sheet formed of a rubber-like elastic material in which a heat conductive filler is mixed. Thus, if a semiconductor device on a board generates heat, it is possible to suppress local heat storage by the heat conductive filler of the base sheet. Further, there is no need to provide a separate member for heat diffusion between the board and the key sheet, making it possible to realize a reduction in thickness. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses, and the requirement for a reduction in the thickness and weight of electronic apparatuses.
