The Extron MSW 4 Series four input active mini switchers are part of the Extron VersaTools product line. There are three models in the series.

The MSW 4V is a composite video switcher utilizing BNC connectors. The MSW 4SV is S-video switcher using 4-pin mini DIN connectors. The MSW 4V SDI is a Serial Digital Interface (SDI) video switcher with buffered, reclocked outputs on BNC connectors. All three models include two parallel outputs for simultaneous viewing on a monitor and projector (the MSW 4SV also features a built-in video encoder to output composite video through a BNC connector to a composite video monitor). Each model also includes a 3.5 mm captive screw contact closure connector for remote control, as well as input selection buttons with LED indicators for each input.

There are 2 basic types of switchers— active and passive. Active switchers switch electronically thru solid state components; passive switchers use mechanical relays. To ensure glitch free transitions, the MSW 4V and MSW 4SV switch during the vertical interval of the signal present on input one. Autoswitching is also available on all three models, selectable via buttons on the front panel. An LED on the front panel indicates that the autoswitching feature is on. The MSW 4V and MSW 4SV are compatible with NTSC, PAL, and SECAM video formats, while the MSW 4V SDI is compatible with composite (143 and 177 Mbps), component (270 Mbps), and wide-screen (360 Mbps) serial standards. Each rack-mountable MSW 4 switcher comes in a 1U high, quarter width metal enclosure.
