Maybe this was meant to be a joke, but that’s not how it works. If it were the switch would also not do anything, because what the switch does is exactly the same as unplugging the thing, i.e. cut a piece of the wire out.
Edit: unless you meant for safety reasons, in which case the shutter inside is a lot safer than the button.
Even if you unplug it, the socket is still live at more than 200 V.
