Scart changer for monitors?

Ok you know how let's say you have a an xbox, playstation, dvd player and a sattelite box for your tv, you'd have a panel where you plug in all the video outputs for it, and then you'd have that panel plugged into the tv. You'd then switch between each device using ons on the panel. I dont know what these are called but many people have them. Now I have my xbox set up so that i plug my monitor into it to use as an output device but I also use this same monitor for my PC. Does a device that i described for the tv exist for computer monitors so I can easily switch between my xbox and pc?
