The coax switch is a device used in telecommunications and broadcasting systems to route signals between different coaxial cables. It allows for the selection of different input sources and the routing of those sources to different output destinations. The switch operates by using electromechanical or solid-state components to open and close circuits, effectively connecting or disconnecting the desired coaxial cables. This enables the user to easily switch between different input sources, such as antennas or satellite dishes, and direct the signal to the desired output, such as a television or a receiver.
