A KVM switch pushes multiple video and peripheral signals and produces a single output to a single keyboard, video or mouse, allowing for quick access to several computers and data sources.

Some KVM switches allow users to alternate audio and USB devices between computers and many are designed for connections of up to thousands of users and servers controlled from a single console.
