Simplecom KM320 4-Port USB Switch with USB-C

Sharing USB devices between two computers usually means unplugging and replugging cables every time you switch — which gets old fast. The Simplecom KM320 USB switch lets you share up to four USB peripherals between two computers with a single button press, keeping your desk tidy and your workflow smooth.

The four-port hub includes one USB-C and three USB-A downstream ports, so you can keep your keyboard, mouse, USB drive and printer all connected at once. SuperSpeed USB 3.2 Gen 1 supports data transfer up to 5Gbps, and it’s backward compatible with USB 2.0 devices. Two LED indicators show which computer is currently active, so there’s no guessing.

Setup is plug-and-play with hot-swap support — no drivers needed, and it works across Windows, macOS and Chrome OS. A DC 5V USB-C port provides optional external power input for stable operation when running higher-power devices.
