The Switch Room is located in the Control Sphere directly beneath the Control Room. It routes signals from the Master Control Console to the rest of the TARDIS via transdimensional circuits and links. A hatch in the floor of the Control Room provides access to the Switch Room. The Artron energy stream from the Dynamorphic Generators travels through the middle of the Switch Room and connects with the Master Control Console's Heart (the Main Space-Time Element). From there it is released into the Vortex as counter-magnetization thrust which propels the TARDIS through the Vortex.
