The utility model relates to a power on and off control structure and is applied in a power supplier provided with an active factor correction unit, a main power system and a regular power system. The regular power system provides the regular power required for the startup of the main power system, and consists of a voltage detecting unit capable of producing a drive signal, and a regular power output unit receiving the drive signal and starting the output. The voltage detecting unit is connected with a logic signal switch. The logic signal switch controls the voltage detecting unit to output the drive signal normally or stop the drive signal from being output to the regular power output unit compulsively, so as to turn off the power supplier compulsively. Moreover, as the drive signal is provided with a small electric current, the danger of electric-shock, which happens easily with a known structure, can be avoided and the dimension and the cost can be reduced. |
