Four-Port KM Switch with Mouse Roaming
This StarTech KM switch lets you control four computers with one USB keyboard and mouse. It supports USB 3.0 peripheral sharing and includes 3.5 mm and USB audio connections. The unit ships with a universal power adapter and a quick-start guide. TAA compliance makes it suitable for government procurement.
Ideal for Multi-System Workstations
Operators who need instant cursor movement across four separate PCs will benefit from the mouse-roaming feature. Users who require video switching or monitor sharing should look at a KVM model instead. The switch does not support video signal routing of any kind. Buyers needing display switching must choose a different product class.
Keyboard and Mouse Switching Only
The device provides USB keyboard and mouse switching for four computers without any video ports. This single distinction determines whether the unit fits the intended workflow. Verify that your setup requires peripheral sharing alone before purchase.

Questions about this item
How do I connect four computers to the P4A20132-KM-SWITCH and what step is often missed?
Connect each computer with a USB 3.0 cable to the switch, then attach one keyboard and mouse to the console ports; the step often missed is plugging in the universal power adapter so the switch can manage all four ports reliably.
What maintenance or replacement will the P4A20132-KM-SWITCH need over time?
The unit has no user-serviceable parts; keep the vents clear of dust and replace the universal power adapter only if it fails, using a matching 5 V DC supply with the correct barrel connector.
What limit appears first when the P4A20132-KM-SWITCH runs continuously under load?
The 1.3 in height enclosure limits passive cooling, so sustained full-port USB 3.0 traffic can raise internal temperature until the switch throttles or shuts down to protect itself.
