The Extron SW VGA Series are active switchers utilizing 15-pin HD connectors. There are six switchers in the series. The SW2 VGArs, SW4 VGArs, and SW6 VGArs are two, four, and six input, one output switchers that allow multiple VGA-QXGA computer inputs to be switched to one compatible display. The SW2 VGA Ars, SW4 VGA Ars, and SW6 VGA Ars are also two, four, and six input, one output VGA and audio switchers, but also include several audio features such as active PC audio interfacing which accepts unbalanced computer-generated stereo audio input signals on 3.5 mm stereo mini jacks and outputs balanced line level stereo audio on a captive screw connector.

The SW VGA switchers are user-configurable for manual or autoswitching modes. The autoswitch function can be enabled or disabled via the front panel buttons. Autoswitching allows any input of the switcher to be selected automatically when the switcher detects a sync signal. The 9-pin female D connector enables RS-232 control, as well as contact closure control, and is compatible with the Extron KP 6 Keypad Remote Control and the Extron IR 102 Kit IR remote. All of the SW VGA models are 1U, half rack width metal enclosures that will fit into an optional Extron 1U Universal Rack Shelf Kit.
