A KM switch allows an operator to conveniently control and manage multiple devices, such as PCs and servers, from a single keyboard and mouse console. 

The Lindy 4 Port USB 2.0 & Audio KM Switch is a desktop solution for providing control over four PCs with independent displays from a single keyboard & mouse. Switching between computers can be done by pushing buttons on the front panel of the unit and via keyboard hotkeys; with Mouse Roaming hotkey functions, the user can seamlessly switch between the PCs just by sweeping the mouse cursor across screen borders in different layouts.

The audio output port allow users to connect headphones or speakers to add immersive 2CH audio, while additional USB peripherals can be integrated with the 2 ports USB 2.0 hub. Both audio and USB hub can be switched together with the computers or kept binded to the selected port.

The KM switch can be managed with hotkey switching under every OS without any restrictions. Installation is quick and simple with no software required (BIOS is not supported). The KM switch can be used with standard wired keyboard & mouse.

Simple to set-up and compatible with a wide range of Lindy USB Extenders, this solution is ideal for small education and business environments, control rooms or for helping make the most of IT equipment in the home.

Please note: wireless devices may not always be recognized.
