Patent ID: 7449651

Claim:
A press key structure, comprising: a keycap, configured with a bottom surface; a substrate, disposed beneath the keycap; a first movable panel; and a second movable panel; wherein the first and the second movable panels are disposed in a space sandwiched between the substrate and the keycap while enabling the first and the second panels to pivotally couple with each other by the use of at least a flange and at least a groove formed respectively on the neighboring edges of the first and the second movable panels in a manner that the at least one flange is slidably inset into the corresponding at least one groove; and the each of the first and the second movable panels is coupled to the substrate by a position nearing the center thereof while enabling the two edges of the first and the second movable panels that are away from each other to pivotally coupled to the bottom surface of the keycap, and thereby, a first angle is included between the first and the second movable panels when the keycap is not subjected to a pressing force, and a second angle that is larger than the first angle is included between the first and the second movable panels when the keycap is pressed.
