Fast return switch

A fast return switch was a component of a TARDIS that returned the vessel either back through time or to a previous location in space and time.

After leaving Skaro, the First Doctor used his TARDIS's fast return switch in an attempt to return Ian Chesterton and Barbara Wright to 1963. However, the spring in the switch became stuck. This would have caused the ship to go back in time to the creation of a solar system. As this would have resulted in its destruction, the TARDIS crashed itself and attempted to warn its crew of the danger, eventually succeeding. (TV: The Edge of Destruction)
