The Power Switch is a utility found in most Zombies maps. It is not seen in Nacht der Untoten, Shi No Numa, Dead Ops Arcade, Nuketown Zombies, Bus Depot, Diner, Farm, Town, Mob of the Dead, Origins and Shadows of Evil. It turns on the power, which in turn is used to use the Pack-a-Punch Machine, Perk-a-Cola machines and other utilities, such as Electro-Shock Defenses. Power switches also appear in Exo Zombies and Call of Duty: Infinite Warfare Zombies mode, labelled as a Generator.
Information in the descriptions refers to other actions using the power switch does other than those stated above.Mystery Box. Using it opens the door dividing the two starting rooms.
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.
The switch is backstage, next to the M16. Using it draws back the curtain, opens the door in the lobby and activates the projector. It also lets Crawler Zombies spawn from then on. It then allows the player(s) to link and use the teleporter.
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. It also allows Space Monkeys to spawn.
Two power switches are located underground near the Bowie Knife where the water falls from the ceiling to turn the turbines. These power switches activate the water (each switch activating each side) and the power won't turn on until both switches are pulled. Because the switches are associated with water flow, the Water Slide can't be used without them pulled. Turning on the power also lets the player(s) use the Mine Cart.
The power switch is located in the center of the map by the pyramid and Stakeout. In addition to its basic functions, it restores oxygen and gravity to certain areas of the map and allows the Excavators to start breaching the base.
The separate maps do not require a power switch, but Tranzit does. It is located at the Power Plant and needs to be built from three parts: a power board, a lever, and a zombie hand. They can be randomly found:
- In the first hallway upon buying the door to the reactor, against a wall or lying on the floor, opposite the zombie barrier.
- Scattered around the reactor, varying from lying near a railing, the pipes, or either set of stairs, to laying near boxes at the bottom of the stairs or the one-way ramp.
- In the same room as the workbench, on the computers to the left and right of the workbench, or in a corner to the right of the zombie barrier.
Turning on the power will set the Avogadro free and it will roam the map from then on as a thunderstorm. The power will turn on green streetlights scattered at or between the bus stops that can be used to make portals from the Denizens. It will also open the exit door to Tombstone Soda, the workbench for the Electric Trap, and the spool-and-wires piece for the Jet Gun. For the first time in Zombies, the power can be turned off after it has been turned on. This option is required to go forward with Maxis' path in the Tower of Babble Easter egg.
There is a rare glitch making the zombie hand impossible to pick up thus making it impossible to turn on the power.
It is located on the second floor of the second building in a sewing room. Using it will activate the Elevators which contain the Perk-a-Cola machines and the Pack-a-Punch Machine inside them and can help the players go up and down floors.
It is located on the second floor of the Candy Shop, and it can also be turned on by round 1.
The Power Switch can be found in the Armory next to a bunch of generators.
Turning on the power in Zetsubou No Shima is more complicated than previous maps. Before the player can access the actual power switch, they must first pick up a bucket which is randomly placed in the map, fill it with water from one of the ponds infected with Element 115, and then use it to fill the two water-based power switches. This must be done twice, once for each switch. After this is done, there is a bunker door which the player can open for free by holding the "use" button on it when the prompt to do so shows up. Opening this bunker will reveal several zombies and a Thrasher. The player must kill the zombies (or ignore them) and enter the bunker.
After the player enters the bunker, there will be an area with a regular Power Switch that can be accessed through a door that costs 1500 points; three out of four of the lights above the switch should be green, the other two should be red. This is because the player must clean off webs that are on one of the pipes in the underwater section near said switch. Going up to the Power Switch will bring up a prompt regarding this step. Once the player has cleaned the pipe off, the entrance to the underwater section will close off for a few minutes and the player must fight off hoards of zombies that do not count towards the normal zombies, and do not give the player points. The player must also occasionally get more air by going up to the top at the areas where water does not reach the ceiling, and by shooting the underwater spores, which will give the player more air. After a few minutes, the entrance to this area will reopen, and the player can then proceed to turn on the Power Switch as they normally would in another map.
Going back to simpler power methods, in Gorod Krovi, the power switch is located past the entrance of the Dragon Command Center.
In Exo Zombies, power switches function much differently. There are multiple power switches spread throughout the map, and each one, when activated, will give the player access to certain features requiring power to be accessed. A power switch will give 100 credits to the player who activated it.
