Installation is easy.
You plug the Macintosh monitor into the center socket on the switchbox, and run the two provided cables from the two side sockets to the two computers. If you have a Multi-Scan Display and one of the computers is a PC, insert the adapter provided with the display between the PC and the cable from the switchbox. Then turn on the computers and switch between them. The MacSwitcher saves bother and expense for owners of PowerBooks. When you unpack the PowerBook and put it down on the desk, just plug the free cable into the PowerBook, power it up, and turn the switch on the switchbox for quick and hassle-free external video.
