Sanwa Supply Keyboard and Mouse PC Switch SW-KM2UU (21)

You can switch between two computers using a single USB keyboard and USB mouse. Switching between computers is as simple as pressing a computer's hotkey (Ctrl or Scroll Lock) twice. You can instantly switch to the other computer. Because it emulates the keyboard port, you can start using the keyboard immediately after switching. It is possible to start up two connected computers simultaneously. A complete boot is possible without switching ports during a restart (reboot). The USB port for the mouse has a pass-through design, allowing the use of tilt wheel functions and multi-function mice.
