Product information

Description

The ATEN US421A-AT is a 4-port USB 2.0 peripheral switch that lets up to four computers share a single USB peripheral device, such as a printer, scanner or external storage, on a one-at-a-time basis. The unit includes a USB Type-A to Type-B cable (1.8 m) and user instructions. It has a compact plastic housing (104 mm x 79.6 mm x 22 mm) and complies with RoHS standards.

Advantages

The USB Peripheral Switch ATEN US421A-AT provides simple manual switching between four computers without needing to disconnect cables. It supports USB 2.0 data transfer rates and uses a standard USB B console port for easy connection to a peripheral device. The compact footprint and lightweight construction make it easy to place on a desk or integrate into existing workspaces. RoHS compliance ensures reduced hazardous substances.

Suitable for

Sharing a single printer or scanner between multiple computers
Accessing an external USB storage drive from different workstations
Small office or home office environments with several PCs
Workstations that require occasional manual switching of USB peripherals

The reviewed product USB Peripheral Switch ATEN US421A-AT is a USB peripheral sharing switch designed to connect up to four computers to common USB devices. In this comparison, we evaluate it against similar ATEN models varying in port counts, as well as multi-functional KVM switches that handle both USB peripherals and video signals. The fundamental difference lies in their purpose: peripheral switches share USB devices among multiple computers, whereas KVM switches also consolidate monitor, keyboard, and mouse control.

⚙️ The table below compares essential specifications, including the number of controlled computers and interface types, to help you understand the practical capabilities of each option for your workspace.
