Four-Port USB KVM for Multi-System Control

The Golden Blue switch lets one keyboard and mouse operate up to four computers through four USB-B inputs and two USB-A outputs. It targets users who need simultaneous control across separate machines without installing drivers on Windows, Linux or other supported platforms. A metal shell and gold-plated connectors provide shielding for stable signal paths.

USB 2.0 Speed with Four-Channel Headroom

Propagation uses USB 2.0 full-speed technology, giving enough bandwidth for standard keyboard and mouse traffic across all four ports. The 6 W maximum draw is covered by an external 5 V / 2 A supply, so the hub does not rely on host bus power. Operation is rated from -5 °C to +65 °C, ensuring function in typical indoor environments.

Metal Build and Hot-Key Switching Included

The all-metal frosted enclosure and thickened gold-plated interfaces are the physical accessories that improve durability and interference resistance. Hot-key commands and mouse traversing let users move the cursor across screens or toggle ports instantly. No software bundle or additional cabling is mentioned in the specifications.

Questions about this item

Will the four USB-B inputs share one keyboard and mouse with my existing USB-A peripherals?

Yes, the switch provides four USB-B upstream ports and two USB-A downstream ports so one keyboard and mouse set controls up to four connected computers.

How do I confirm the metal-cased switch is operating correctly after connecting four PCs?

Press the front-panel button to cycle through ports 1 to 4; the corresponding LED lights and the mouse cursor traverses each screen without driver installation.

Does the package include the 5 V / 2 A power adapter and the four USB-B cables needed for four computers?

The box contains the KVM unit only; a 5 V / 2 A power supply and four USB-B to USB-A cables must be purchased separately.
