Switch Block for computer grounded power plug

I don't know about you but I seem to have an endless supply of grounded computer power cords laying around from old computers long since gone. This allows you to use them with a switch and fuse connection. There are two small holes on the top and the bottom. They may not be seem as necessary but actually they are. Once you push the switch/fuse block into the printed holder it will not com out unless you push in the latches through these holes.
I got the plug and switch block from Amazon. To find the switch block that fits do an Amazon search for:
