Extron SW4 4-Input RGBS Analog Video Switcher BNC 4x1 Loop Control Remote
The Extron SW4 is a 4-input, 1-output analog video switcher designed for RGBS (Red, Green, Blue, Sync) video signals. It routes one of four RGBS sources to a single display or downstream device, with input selection via four front-panel illuminated pushbuttons. The unit also provides a Loop Control BNC output and a Remote Control port for external switching. The chassis is full metal construction in a compact desktop form factor.

Applications
The Extron SW4 is a straightforward RGBS analog video switcher used in professional AV and presentation environments where multiple RGBS sources — such as computers, CAD workstations, or video systems outputting separate RGB-plus-sync signals — need to share a single display or projector. RGBS switching was common in the 1990s and early 2000s in corporate AV systems, training rooms, control rooms, and engineering environments where analog RGB over BNC was the standard interconnect for high-resolution analog video. Extron is a well-known manufacturer of professional AV signal management and distribution equipment, and the SW series switchers were widely deployed in fixed AV installations. These units remain useful today for legacy RGBS signal routing, retro computing setups, and AV system maintenance where analog BNC-based RGBS infrastructure is still in place.
This Extron SW4 RGBS Analog Video Switcher has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in use. The metal chassis shows the typical light scuffs and surface wear you'd expect on used AV gear. All four front-panel input selector buttons are present, and the rear BNC connectors appear intact with no visible damage. A power adapter is included.
