This series of selector switches was specifically designed to switch DMX512 signals. Originally designed to switch between primary and backup consoles, these switches are often used to select from two (or more) input locations. The SW1 switches a single DMX512 universe (one A input, one B input, one output). The SW4 switches four DMX512 universes (four A inputs, four B inputs, four outputs).
Custom units for switching any number of universes are available. Custom units for switching between more than two input sources are available (A/B/C switches, for example). Custom remote switch units using relays or solid state control in place of the manual switch are also available
