Abstract
A key structure has a support member that reduces manufacturing costs, assembly costs, and the total height of the manufactured product. The support member is mounted between a base and a key cap. The support member has a first frame and a second frame, which are both formed in a united manner by injection. The first frame has a base portion and a pair of side arms connected with the base. The side arms both have a penetrated transverse pivotal hole formed therein. The second frame is disposed between the side arms and has a pair of pivots protruded respectively from two sides thereof. The pivots are formed and mounted directly in the pivotal holes during ejection molding, and an annular channel is formed for receiving a tubular mold during ejection molding.
