Internet Switch

I want something like this centrally located in my house so that I can, with great bravado, threaten the kids that I am going to switch off the internet.  This is my fantasy, that when I say "dinner is ready and it's time to get off the computer/laptop/other device, I mean now!  Don't make me have to use the switch."

I'd have the modem wired through it and then have it located in a nice visible area where I can make a big show of going over to the switch. Then I could put my hand on it and threaten, "I'm gonna do it".
I could then drag out the action of wrenching the switch from the on to the off position.

I would also like to imagine, the sounds of whirring industry slowly winding down, as all the devices and computers grind to a halt.  Silence would descend for a split second before the indignant voices of protest rise up to complain about the unfairness of it all.  I could stand there smugly saying "I warned you".

Ahhh to be never ignored again when I tell the kids to come to dinner, go to bed, have a shower..... or whatever other requests I may make of them that would require them to physically extract themselves from the magnetic pull of their chosen technology.

Someone should market this idea and give me a chance to live out my dream.  Imagine a ceremonial shutting down of the wifi at bedtime, it would give me such pleasure.  I know I can achieve the same ends with the itty bitty button on the back of the modem, but somehow it lacks the drama and theatre that the big wall mounted switch would have.
