TERMINAL HAVING CURRENT SENSING TYPE BUTTON

摘要

PURPOSE: A terminal having a current sensing type button is provided to input data by sensing a minute current which flows in the human body. CONSTITUTION: A current sensing button(110) has a plating film plated by a conductive metal at a part of the surface of the plating film. A current sensing circuit(130) coupled with the current sensing button at a suitable interval has an electrode plate electrically connected to the plating film of the current sensing button. A switching circuit(140) senses a minute current which flows through the electrode plate of the current sensing circuit(130), and generates a switching signal. The current sensing button is formed by directing processing the conductive metal. An ESD(ElectroStatic Discharge) preventing unit(120) prevents ESD generated by the contact of the current sensing button.
