4-Port USB 3.0 KVM Switch

This WRIARICH KVM switch lets a single operator control four separate computers while sharing four USB 3.0 peripheral devices. It suits home offices or small workspaces where a keyboard, mouse, printer and external drive must move between multiple Windows or Mac systems without unplugging cables.

Four USB 3.0 ports and one-button switching

Four USB-A to USB-A cables are included so each host can connect immediately. The switch draws power from the USB bus, so no external adapter or driver installation is required. A single press moves all four peripherals to the next computer, freeing desk space and eliminating cable swapping.

Bus-powered operation under continuous use

Because the unit relies on host bus power, sustained throughput across all four ports depends on the power budget of the connected computers. Heavy simultaneous transfers on multiple external drives may exceed that budget, making the switch best suited to typical office peripherals rather than high-draw storage arrays.
