Specialized Key Switches for Electronic Key Caps

A keyboard key switch comprising:

• an upper casing having a space for a plunger;
• a lower casing coupled with the upper casing to form an interior space;
• the plunger disposed in the space;
• the plunger having a protrusion on a top portion;
• the protrusion having a first conductive region, a second conductive region, a third conductive region, and a fourth conductive region;
• wherein the first conductive region, the second conductive region, the third conductive region, and the fourth conductive region each extend to a bottom surface of the plunger;
• a first spring probe, a second spring probe, a third spring probe, and a fourth spring probe, each disposed at least partially within the interior space;
• wherein a bottom portion of the first spring probe, a bottom portion the second spring probe, a bottom portion the third spring probe, and a bottom portion the fourth spring probe extend through a bottom surface of the lower casing;
• and
• wherein a top portion of the first spring probe, a top portion the second spring probe, a top portion the third spring probe, and a top portion the fourth spring probe each contact the first conductive region, the second conductive region, the third conductive region, and the fourth conductive region, respectively, on the bottom surface of the plunger.
