Arrange the power switch for the computer, connect to the socket.

I connect an additional external switch, for the computer's power source to be safe when not in use, avoiding electrical problems with the computer and other devices.
I use a 4-pin switch to turn on or off the power for the device, connect the 2 ends of the wire to the 2 Line pins, the remaining 2 ends of the wire to the 2 Load pins of the switch, connect to the 4 pins of the switch. The remaining two ends of the wire connect to the socket.#switch#powerpc
