Abstract
A key switch includes a key cap which includes a top wall, a pair of pivot retainers and a pair of latch retainers. Each pivot retainer has a distal end disposed away from the top wall, two opposite side faces, a pivot hole extending through the side faces and opening at the distal end, and a guide rib projecting from one side face. The guide rib is tapered from the top wall toward the distal end and defines an inclined guide surface. A cap support has pivotally interconnected first and second frames which are connected to the key cap. The first frame has two inclined surfaces which are slid along the respective guide surfaces when the cap support is pressed against the key cap for assembly.
