Four-Computer USB 3.0 Sharing

This SMA switch connects four computers to four USB peripherals through a single push-button. It targets home-office users and small teams who need to share a printer, scanner, keyboard, mouse or external drive across multiple PCs without unplugging cables. Driver-free operation supports Windows, macOS, Linux and Chrome OS out of the box.

Sustained-Load Behaviour

The unit draws power from the host USB ports and requires no external adapter. The supplier notes that running several high-draw devices such as multiple hard drives or scanners simultaneously may exceed the available bus power. Aluminium housing helps dissipate heat during continuous switching sessions.

Aluminium Build and Cabling

A compact aluminium alloy chassis provides durability and passive cooling for daily desk use. Four USB Type-A to Type-A cables are included for the computer links. LED indicators show the active host at a glance. The switch is not designed for video signals or for setups that need more than four connected computers.

Questions about this item

Does the aluminum case keep the switch cool when it runs all day?

The aluminum alloy chassis dissipates heat passively so the unit stays cool during continuous use without needing a fan or external power supply.

Which cables must I already have to connect four computers?

The box includes four USB Type-A male-to-male cables, so you can link each computer directly without buying extra cables.

Will the push-button and LED indicators still work if I keep an older Windows 7 or Vista machine in the mix?

Yes — the switch is driver-free and supports Windows 10, 8.1, 7, Vista and XP, so legacy PCs switch just like newer ones.
