ABSTRACT:
The present invention provides a micro power switch comprising a cold cathode for emitting electrons, an anode for capturing the electrons emitted from the cold cathode, and a control electrode for controlling an amount of the electrons emitted from the cold cathode, wherein the cold cathode is made of material having a smaller electron emission barrier than the control electrode, the anode is applied with a positive potential in relation to the cold cathode, and the control electrode is applied with a potential equal to or lower than a potential of the cold cathode.
