PURPOSE: A power switching module for an electronic device is provided to improve functionality of the electronic device and convenient of use by controlling power supply state of the electronic device and embodying various operations of the electronic device. CONSTITUTION: A printed circuit board(100) comprises a common contact point(110) connected to a power supply source, and supply contact points(120) outputting a different current. A contact point leg(200) selectively interlinks the common contact point and one supply contact point. One among the supply contact points is connected to a resistance(130). The common contact point is formed into an area capable of accepting contact during up and down movement of the contact point leg.
