Abstract:
1. A thin key structure, comprising: a supporting module having a supporting plate and a protrusion, the supporting plate having a plane defined therein and a central axis perpendicular to the plane, and the protrusion is arranged on the central axis; a circuit module disposed on the supporting plate abutting the protrusion, and the circuit module having a protruding segment formed thereon abutting the protrusion; a frame disposed on the circuit module and defined with an accommodating space; a metal dome disposed on the circuit module and in the accommodating space, and an inner portion of the metal dome defined with a contact portion substantially aligning with the central axis; a pressable module disposed on the frame and at least a portion of the pressable module is configured above the metal dome; and a guiding portion configured to align with the central axis and between the contact portion of the metal dome and the pressable module; the guiding portion is formed on the metal dome or the pressable module, wherein the pressable module is configured to be pressed for deforming the metal dome by the guiding portion to displace the contact portion from an original position to a conductive position along the central axis, when the contact portion is at the original position, the contact portion and the circuit module are configured with a gap therebetween and when the contact portion is at the conductive position, the contact portion presses the circuit module.
