a torsion spring, wherein the torsion spring is configured to make a click sound when acted upon; and

a click bar, wherein an overhang of the click bar is positioned over a portion of the torsion spring;

wherein the portion of the torsion spring that is positioned under the overhang contacts the click bar when the stem is depressed resulting in a first click sound, and the portion of the torsion spring that is positioned under the overhang contacts the click bar a subsequent time when the stem is released resulting in a second click sound.

2 . The key switch of claim 1 , wherein when the stem is depressed, the torsion spring flexes in a downward direction, and when the stem passes a predetermined threshold, the portion of the torsion spring under the overhang will release and contact the click bar producing the first click sound.

3 . The key switch of claim 2 , wherein when the stem is released, the torsion spring flexes in an upward direction, and when the stem passes the predetermined threshold, the portion of the torsion spring under the overhang will release and contact the click bar producing the second click sound.

4 . The key switch of claim 1 , wherein the first click sound and the second click sound are of equal volume.

5 . The key switch of claim 1 , wherein a portion of the torsion spring extends outside a top portion of the switch housing.
