A lever is a device that can be linked to other devices to control them. A lever is pulled through its q menu with aP. A nearby dwarf will then pull it. Pressure plates are like levers, but are activated automatically by creatures stepping on it.

Levers have an 'on' and a 'off' state. Upon being flipped, everything they're connected to updates to the lever's new state. This becomes important if you have several levers attached to the same building.

Objects that can be controlled by levers include:

Multiple Uses

  • Bridge – Lever On: Turns the bridge into either a raised drawbridge, or a retracted bridge, depending on which option was chosen when the the bridge was constructed. Lever Off: Returns the bridge to normal.
  • Door – Lever On: Opens the door. Lever Off: Closes the door. Note that once you connect a door, it is either completely open, or locked. There is no "closed, but can be opened by a dwarf" state anymore.
  • Floodgate – Lever On: Opens the floodgate. Lever Off: Closes the floodgate. After the lever is installed, it works exactly like a door.
  • Hatch – Lever On: Opens the hatch. Lever Off: Closes the hatch. When open it just disappears and allows water through. Note it is suspected that like doors - once you connect a hatch, it is either completely open, or locked. There is no "closed, but can be opened by a dwarf" state anymore.
  • Grate – Lever On: Opens the grate. Lever Off: Closes the grate. When it it open, it just disappears. Water goes through it just the same, but it cannot be walked on anymore. Anybody on it will probably fall through (more testing needed).
  • Upright Spear/Spikes – Lever On: Retracts spears/spikes. Lever Off: Extends spears/spikes.[Verify]
  • Gear assembly – Lever On: Disengages the gear assembly. Lever Off: Engages the gear assembly. When it is disengaged, no power goes through it and anything on top of it falls down.

One-Shot

  • Cage/Restraint – Opens the cage/chain/rope and releases whatever it held. This is permanent and you will have to reinstall and relink the cages/restraints after one use. You recover the mechanism used in the cage/restraint.
  • Support – Deconstructs the support, except without a dwarf next to it. Most commonly used to effect caveins.
