ABSTRACT:
The invention provides a power switch device for electronic systems equipped having a power module. The power switch device includes a first switch for activating a first signal, a second switch for activating a second signal, a logic judging module for receiving the first and second signals for logic algorithm processing, and a control module electrically connected to the electronic system and the logic judging module. The control module is adapted to generate and transmit on and off signals of the electronic system to the logic judging module. Further, the control module controls switching on the power module according to the off signal and the logic algorithm processing based on the first signal, and also controls switching off the power module according to the on signal and the logic algorithm processing based on the first and second signals.
