Control up to four computers with a single keyboard and mouse

This Keyboard and Mouse (KM) Switch enables switching a single keyboard and mouse between multiple computers using mouse roaming, allowing users to seamlessly move the cursor across multiple screens (i.e., one monitor per computer).

Mouse Switching

Switch between computers by moving the mouse between monitors, enabling uninterrupted workflow and increased efficiency. Hotkey and push-button switching are universally compatible. Mouse Switching is supported by most major desktop operating systems, including Windows, macOS, and Linux.

Preset Monitor Layouts

To accommodate various physical monitor setups, there are four preset display configurations available. This allows for smooth mouse movement across host monitors.

Thoughtful Design

Hotkeys enable listening to audio from one computer while controlling another. USB audio and 3.5mm pass-through are available, and LEDs provide visual port selection status, while an audible buzzer confirms hotkey selection.

Note: On computers with multiple monitors connected with Mouse Switching/Roaming enabled, mouse/keyboard operation is limited to the primary display

Returns FAQs

What is your returns criteria?
14 days from date of receipt, or expected date of receipt on non-tracked items.

How do I go about returning my order?
Please contact us via our contact page with your order number. We will provide you with an RMA number and return instructions, including your return deadline and whether a freepost label applies to your order.

Do I need to contact you before returning my order?
Yes, to obtain an RMA number before sending anything back.

Does my item have to include its original packaging?
Yes, to qualify for our 14 day money-back guarantee. For faulty items, we understand you may no longer have the original packaging.

Who pays for return postage?
If your item is faulty, damaged, or not as described, we cover reasonable return postage, or provide a freepost label where available. If you are returning an item for another reason (including simply changing your mind), you are responsible for return postage unless we have expressly confirmed a freepost label in your RMA email — we recommend using a tracked and insured service for items of significant value.

We will. In some circumstances we may ask you to contact the manufacturer directly for assistance.
