The Actuator is a mechanism item purchased from the Mechanic for 10 Silver Coin each. It has to be connected with Wire to function. When activated, the tile it sits on toggles between active and inactive state, effectively allowing any block to be toggled like Active Stone Blocks. Like wire, Actuators are normally invisible and only become visible when a mechanism item is selected.

The following items interact with Actuators:

  • They can be removed with the Wire Cutter or The Grand Design.
  • The Presserator automatically places Actuators on objects when placing them. It requires a sufficient supply of Actuators in the player's inventory in order to function.
  • The Actuation Rod can toggle any Actuator within a limited range without requiring wire.

Notes[edit | edit source]

  • Actuators can work on platforms and teleporters, but otherwise only work on blocks and traps.
  • Most furniture on top of a block/platform with an actuator will be freed when the actuator activates.
  • Actuators won't activate if they are directly beneath a tree, Demon Altar, Crimson Altar, or any chest (regardless of whether it contains items or not).
  • Any plants growing on a block which is put into its inactive state by an actuator will be destroyed as if a tool was swung at it. This can be used to harvest mushroom farms. Herbs, however, will remain on the inactive block.
  • Liquids can pass through blocks which an actuator has made inactive, but falling blocks like sand, silt and slush will still be supported.
  • Inactive Ebonstone, Crimstone, and Pearlstone Blocks will still count towards the formation of their respective biomes.
  • Naturally occurring Lihzahrd Bricks cannot be actuated until Plantera has been defeated.
    • This is designed for balancing reasons and as a leftover from 1.2, because Temple Keys can be used to craft Biome Keys, and using Actuators will allow access to the Jungle Temple without using the key.
    • In the Mobile version Mobile version, the player can use Actuators on Lihzard Bricks in order to remove the Lihzard Altar and drop it as an item.
  • NPCs can spawn on top of actuated blocks and thus fall through them.
  • In the Console version Console version, the locked Jungle Temple door is able to be actuated.
  • A Portal Gun can place portals on blocks that have Actuators on them. This works if the block is activated and deactivated after placing the portal.
  • Actuators have no effect on bubbles.

Tips[edit | edit source]

  • Using Actuators in place of doors creates entrances that can completely block off the enemies from a Blood Moon or other events.
  • Because they work on traps, it is possible to load up several traps in a row, and none of their attacks will be blocked by traps ahead.
  • Actuators can be used to pass through Hellstone in the Underworld without generating lava, and can similarly be used to pass through hive blocks without generating honey or spawning bees. The Actuation Rod may be used to quickly activate placed Actuators.
  • If you stand inside an inactive block and it becomes active, you will be able to move inside the 6 blocks you are in but will be stopped by other blocks. This may be used for protection.

Trivia[edit | edit source]

  • The Multicolor Wrench is not capable of removing Actuators, even though it is crafted using the Wire Cutter, which does remove Actuators.

History[edit | edit source]

  • Desktop 1.2.4: Actuated tiles no longer remove the water over them on world load.
  • Desktop 1.2.1.2: Actuators no longer work on unlocked or made by and/or placed down by man doors.
