An activation signal (TV: ) also called an activation trigger, (PROSE: ) was a signal transmitted by the Nestene Consciousness via the London Eye to control the Autons.

Judd speculated the activation trigger's additional property was due to the Consciousness being weak to certain signals. (PROSE: )
