Switchers enable multiple signals to be selected and sent to one or more display devices. For example, to view two computers, with separate presentations, on a single display, a switcher is used to physically connect both of the inputs to the display device. The switcher then provides selection between the two computer presentations, allowing the user to alternate back and forth.

Commonly used signals include VGA, composite video, RGB, and stereo audio. Common connectors include BNC, S-video, and 15-pin HD.

Switchers can be used in a wide range of applications where multiple video and/or audio sources are being displayed by one or more devices. This includes environments such as lecture halls, conference rooms, and home theatres.
