Abstract: A computer key includes a one-piece base plate which is punched to form left and right retaining guideways that are spaced from each other in a longitudinal direction of the base plate. The retaining guideways include left and right retaining portions which extend uprightly from the base plate, and left and right blocking portions which extend from distal ends of the retaining portions away from each other and substantially longitudinal to the base plate. The blocking portions have left and right widths defined in a direction transverse to the longitudinal direction by front and rear left and right rough edges. A frame assembly includes first and second linking frames which are pivotally connected at intermediate portions thereof.
