Power Switch

The power switch is a utility found in most Zombies maps. It is not seen in Nacht der Untoten, Shi No Numa, or Dead Ops Arcade. It turns on the power, which in turn is used to use the Pack-a-Punch Machine, Perk-A-Cola machines, and other utilities.

Locations
Information in the descriptions refers to other actions using the power switch does other than those stated above.

Zombie Verrückt
It is located on the complete opposite side of the map. The switch is on the opposite side of the room of the Mystery Box. Using it opens the door dividing the two starting rooms.

Der Riese
The switch can be found in the courtyard attached to a giant generator. Using it lowers a bridge that connects the second floor of the two sides and also opens two doors, letting players move from the courtyard to this area directly instead of going through whichever side they unlocked. It also lets the players use the teleporters.

Kino der Toten
The switch is backstage, adjacent to the M16. Using it draws back the curtain and activates the projector. It also lets Crawler Zombies spawn from then on. It then allows the player(s) to use link and use the teleporter.

"Five"
It is found in the central room in the basement. Using it unlocks the teleporters and the DEFCON Switches. It also lets the Pentagon Thief spawn.

Ascension
Located on the top floor of the main building. Using it activates the Lunar Landers and changes the game from black and white to color.

Call of the Dead
It is located in the uppermost part of the ship. It lets the players use the Flinger and start the Original Characters Trapped easter egg.

Shangri-La
It is located inside near the bowie knife where the water falls from the ceiling. This power switch is not like the rest, because the player must active 2 power switches for the power to activate and appear much older

Trivia

 * In "Five" below the power switch there is some text that says "Hochspannung Vorsicht! Lebensgefahr" (Danger - High Voltage) This is incorrect because "Five" takes place in America and not Germany. This is because the power switch in "Five" has been reused from Kino der Toten with a slightly different appearance.
 * There is an unusable power switch found in the building near the ice cave in Discovery.
 * There is a hand on the power switch in Verruckt and Der Riese, as the power switch was reused.
 * Even though there is no power switch in Shi No Numa, a sign on the zipline next to the starting area says "Switch on power to activate", maybe indicating that a power switch was originally in Shi No Numa.
 * On Shangri-La There are 2 power switches, but they do not turn the power for the first time, instead they make the Water Mechanism start, Giving Power to Things such as perks and traps.
