Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for shutting off power supplied to a load when a power switch of an electronic or electrical device is turned off. In particular, the present invention provides positive and negative power when the power switch is turned off. The present invention relates to a power cutoff device which opens both power lines to completely separate a power supply line and a load so as to prevent leakage current consumption in a no-load state generated at power off. A relay 30 connected to one side terminal 20a and supplying and cutting off a “+” or “−” voltage to the load 60 and consisting of a relay position 31 coil 32 and a magnet 33, and the plug A power switch 50 connected to the other terminal 20b of the power supply 20 for supplying a “+” or “−” voltage to the load 60 to operate the load, and an output terminal of the power switch 50 and the magnetization coil; Connected between the 32 to rectify alternating current in series, A power supply including a diode 40 for supplying an operating current of the relay 30 and a capacitor 70 connected in parallel with the coil 32 and the magnet 33 of the relay 30 to prevent a reverse flow voltage. By providing a disconnecting device, even if the plug is not disconnected from the outlet, the two power lines and the load are completely separated by the operation of the relay when the power switch is turned off, eliminating power consumption in the no-load state generated when the power switch is turned off, It is possible to prevent power waste in the operation of auxiliary devices (lamps, clocks, etc.).
