The Actuator is a mechanism item purchased from the Mechanic for 1000*10 each, or harvested from sand, lava, or Dead Man's Chest traps. 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 DesignDesktop VersionConsole Version.
  • The Presserator automatically places Actuators on objects when placing them, if the player has any.
  • The Actuation Rod can toggle any Actuator within a limited range without requiring wire.

Notes[edit | edit source]

  • In addition to most blocks and traps, Actuators can also activate on teleporters and platforms.
  • 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, Lihzahrd Altar, or any chest (regardless of whether it contains items or not). 1.4.0.5 block actuator protection is present on the 2nd layer of blocks under a chest as well (4 blocks total).
  • 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 and falling blocks like sand, silt and slush can pass through blocks which an actuator has made inactive. Console version Console, Old-gen console version Old-gen console, Mobile version Mobile, and 3DS version3DS Falling blocks won't pass through.
  • 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 was originally possible by intention, because Biome Keys previously did not drop directly and required a Temple Key to craft. This was changed in 1.2 to remove the Biome Key Mold items, and in turn the need to consume Temple Keys.
  • 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.
  • Portal Gun's Portals, if placed before the blocks are actuated, will not vanish and will still function normally.
  • 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.
  • Desktop Version Like naturally-generated wires, naturally-generated Actuators can be harvested, though they appear much more rarely, saving 1000*10 per Actuator.
  • Actuators are a good tool for terraforming/clearing the way for a plot, especially underground.

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.
    • However, the Grand Design, crafted from the Multicolor wrench, is capable of doing so.

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.
