ABSTRACT:
A press key structure is disclosed, which comprises: a keycap, configured with a bottom surface; a substrate; a first movable panel; and a second movable panel; wherein the substrate is arranged at a position underneath the keycap while disposing the first and the second movable panels in a space sandwiched between the substrate and the keycap and pivotally coupling the two by the use of a flange and a groove formed respectively on the two neighboring edges of the first and the second movable panels in a manner that the flange is slidably inset into the groove; and the each of the first and the second movable panels is coupled to the substrate by 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. With the aforesaid structure, a first angle is included between the first and the second movable panels when the keycap is not pressed by a 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.
