USB switch?

Im looking for a USB switch which will allow my keyboard to be switched between use on my PC and my Xbox. At the moment I'm having to unplug and plug back in which is a real pain and surely cant be doing the connectors any good. Does such an item exist?

hope ye olde hexus can help.

Thanks

something like this might work

I think thats just what im looking for :) thanks

One thing to note is that most switches are generally USB1 only (mine is) - so if you're plugging in a big HD then be prepared to wait when copying files. For keyboards and mice it's definitely fine.
