Two-computer USB 3.0 sharing switch

The Sabrent HB-UM43 lets two computers share one USB peripheral or hub with a single button press. It requires no drivers and draws power from the USB connection. LED indicators show which system is active at any moment. The compact plastic enclosure measures 3.9 cm by 12.2 cm by 16.4 cm and meets CE and IP647 ratings.

Fits between two hosts and one device

Connect each computer to the switch using their available USB 3.0 or 2.0 ports, then attach a keyboard, mouse, storage drive or hub to the shared downstream port. The push-button toggles the connection instantly without unplugging cables. No external power supply is needed because the unit operates from the 5-volt USB bus at 50 milliamps. It frees desk space by eliminating duplicate peripherals.

Sustained 5 Gbps throughput under load

The switch maintains USB 3.0 signalling at up to 5 Gbps during continuous data transfers between the active computer and the shared device. Plastic housing and surface-mount design keep operating temperatures within the rated range of 67 degrees Fahrenheit to -0.01 degrees Celsius. No active cooling is required and the mechanical push-button is rated for repeated daily cycling. The simple ON-ON switching logic avoids protocol negotiation delays during extended sessions.

Questions about this item

What power limit appears first when the Sabrent HB-UM43 runs all day at 5 volts and 50 milliamps?

The switch draws 5 V at 50 mA from the host USB port, so the port’s own current ceiling is the first limit reached under sustained use.

How much noise or heat does the Sabrent HB-UM43 produce during continuous operation?

It has no fan or moving parts beyond the push button, so it runs silently and generates only minimal warmth from the LED indicators.

Which cables and ports must I already have to connect two computers to the Sabrent HB-UM43?

Each computer needs an available USB 3.0 or 2.0 Type-A port and a matching USB cable to reach the switch’s two upstream ports.
