Dual-Function Switch for Stylus Tail Eraser

A dual-function tail eraser button for a stylus, comprising:

• a circuit disposed within a barrel of the stylus, the circuit having at least a first electrode and a second electrode disposed thereon, wherein the first electrode comprises a first pair of electrical traces separated by a first gap and the second electrode comprises a second pair of electrical traces separated by a second gap;
• a conductive polymer disposed within a tail end of the stylus and positioned adjacent to the circuit;
• and
• a microcontroller disposed within the barrel of the stylus, the microcontroller configured to detect an electrical continuity of the first electrode and the second electrode, the microcontroller further configured to output a first signal in response to detecting the electrical continuity between the first pair of electrical traces and output a second signal in response to detecting the electrical continuity between the second pair of electrical traces.

A stylus tail eraser, comprising:

• a dual-function button disposed in a tail end of a stylus;
• a microcontroller disposed within the stylus, the microcontroller configured with instructions that cause the microcontroller to:
• output a first signal in response to a first force being applied to the dual-function button;
• and
• output a second signal in response to a second force, greater than the first force, being applied to the dual-function button.
