Abstract
A power switch system () for selectively providing power from a primary power source and a secondary power source to an electronic device, includes a detecting module (), and a selecting module (). The detecting module is connected to the primary power source. The selecting module is connected to an output terminal of the detecting module, the primary power source, and the secondary power source, and outputs the power from the primary power source to the electronic device if the primary power source is available. The detecting module is configured for determining whether the primary power source is available for the electronic device and generating a switch signal if the primary power source is unavailable, and the selecting module outputs power from the secondary power source to the electronic device in response to the switch signal.
