Abstract
In a key switch device, an outer wall of an engagement member of a key top is interposed between a pinch shaft and an upper shaft of a first link member, while an outer wall of an engagement member of the key top is interposed between a pinch shaft and an upper shaft of a second link member. When the key top is pulled up, the pinch shaft and the upper shaft of the first link member cooperate with each other to pinch the outer wall of the engagement member, and the pinch shaft and the upper shaft of the second link member cooperate with each other to pinch the outer wall of the engagement member. Thus, when the key top is pulled up, the key top is removed together with the first and second link members, thereby facilitating reassembly and maintenance of the key switch device.
