Abstract

A notebook computer key comprises a key hat, a seat, an elastic touch moving piece, a first supporting frame and a second supporting frame. The key hat is formed with an operating surface and an assembling surface at the top surface and the lower surface. The seat is installed with a plurality of through holes, each through hole is installed with a positioning piece. The elastic touch moving piece installed between the key hat and the seat. The first supporting frame and second supporting frame installed between the assembling surface of the key hat and the seat. The two supporting frames are pivotally connected. The upper ends of the two supporting frames are connected to the assembling surface of the key hat, and each lower end of two sides of the two supporting frames are installed with a pivotal shaft for being pivotally connected to the through hole of the seat. The pivotal shaft at lower end of each side of the two supporting frames are protruded from the first lateral wall and the second lateral wall of the supporting frame. The pivotal shaft at each lower end of two sides of the two supporting frames is inserted into the through hole pivoted Therefore, the height of the key is reduced and the requirement of compact of modern products is met.

Claims
