Claim:
1. An output-switch control system for an AC-DC power supply, the output-switch control system comprising: a push-button switch; the push-button switch comprising a lengthwise button, a first trigger, a second trigger, a first spring member and a second spring member; the first trigger and the second trigger being connected to the lengthwise button; the first spring member being biased against the first trigger; the second spring member being biased against the second trigger; the lengthwise button being configured as a self-return button via the first spring member and the second spring member; a detecting circuit; the detecting circuit comprising a first contact and a second contact; the first contact and the first trigger corresponding to each other; the second contact and the second trigger corresponding to each other; the first trigger being capable of separating from the first contact through the first spring member being biased against the first trigger; the second trigger being capable of separating from the second contact through the second spring member being biased against the second trigger; the first trigger being capable of abutting against the first contact through the lengthwise button being pressed; the second trigger being capable of abutting against the second contact through the lengthwise button being pressed; the detecting circuit outputting a power-source-on signal in response to the first trigger abutting against the first contact and the second trigger abutting against the second contact at a first time, and thereafter outputting a power-source-off signal after outputting the power-source-on signal in response to the first trigger abutting against the first contact and the second trigger abutting against the second contact at a second time after the first time; and the detecting circuit outputting the power-source-off signal without outputting the power-source-on signal in response to the first trigger abutting against the first contact and the second trigger separating from the second contact, or in response to the first trigger separating from the first contact and the second trigger abutting against the second contact.
