A redstone torch is a non-solid block that can be used as an invertible redstone power source.

Obtaining[edit]

Redstone torches can be broken instantly using anything, and drop themselves as an item. To remove a redstone torch, use the attack control button .

A redstone torch will also be removed and drop itself as an item:

  • if its attachment block is moved, removed, or destroyed
  • if water flows into its space
  • if a piston tries to push it or moves a block into its space

If lava flows into a redstone torch's space, the redstone torch will be destroyed (burned) without dropping itself as an item.

Natural generation[edit]

Usage[edit]

Redstone torches can be used as crafting ingredients or redstone components.

Crafting ingredient[edit]

Redstone torches can be used to craft activator rails, redstone comparators, and redstone repeaters.

Redstone component[edit]

Redstone torches can be used to power blocks and transmission components such as redstone dust, activate mechanism components such as pistons, or invert redstone signals like a NOT Gate.

Placement
Examples of redstone torch placement and behavior.
To place a redstone torch, use the Place Block control while aiming at the surface to which the redstone torch should be attached.
A redstone torch can be attached to:
Redstone torches cannot be attached to the bottoms of any blocks.
Attempting to attach a redstone torch to an invalid surface can cause it to "snap" to a valid surface adjacent to the same space. For example, if a fence is on the ground, attempting to attach a redstone torch to the side of the fence will cause the redstone torch to be attached to the top of the ground next to the fence instead.

Activation
A redstone torch is active unless the block it is attached to is powered. Effectively, a redstone torch inverts the signal applied to its attachment block: power level 0 is changed to 15 and power levels 1 to 15 are changed to 0 (for an alternative that produces a greater range of output power levels, consider a redstone comparator in subtraction mode).
Walls, fences, glass, slabs, and stairs cannot be powered so redstone torches attached to them cannot be deactivated. Hoppers can be activated but cannot be powered (in the sense that they would power redstone dust next to them), so redstone torches attached to hoppers also cannot be deactivated.
A redstone torch takes 1 redstone tick (2 game ticks, or 0.1 seconds barring lag) to change state and won't change state unless the signal change to its attachment block is at least 1.5 redstone ticks long (unless the change is caused by the redstone torch itself in a "short-circuit"). For example, a redstone torch won't turn off if its attachment block receives a 1-tick or shorter pulse.
Behavior
While active, a redstone torch:
A redstone torch never affects the block it is attached to, even if it is a mechanism component. For example, a redstone torch attached to a redstone lamp will not activate the lamp.
A redstone torch will "burn-out" when it is forced to change state (by powering and de-powering the block it's attached to) more than eight times in 60 game ticks (three seconds, barring lag). After burning-out, a redstone torch will produce a "smoke" particle and a hiss similar to an extinguished fire, deactivate, and will then ignore attempts to change its state until the number of state changes in the last 60 game ticks drops to fewer than eight — after that it will re-activate when it receives a block update (an adjacent block changing its state) or a redstone update which wouldn't normally deactivate the redstone torch. There is no limit on how often a single redstone torch can burn out.

History[edit]

Alpha
v1.0.1 Redstone Torch.pngRedstone Wall Torch Revision 1.png Added redstone torches.
v1.0.2_01 Redstone torch, NOT gates, only signal into blocks above them or next to them.
v1.1.0 Redstone torches can no longer be placed on tree leaves, but only in fancy mode.
v1.2.0_02 Redstone torches no longer duplicate in multiplayer.
Beta
1.2_01 Fixed redstone torches acting proper weird when placed.
1.3 Redstone torches are now used to craft redstone repeaters.
1.6.6 It is now possible to place redstone torches on glowstone.
1.7.3 Corrected a redstone torch duplication bug when using pistons.
Official release
1.2.1 ? 'Burnout' time reduced from 100 ticks to 60 ticks.
1.3.1 ? Redstone torches can now be placed on upside-down slabs and stairs.
1.4.2 ? Redstone torches are destroyed when an anvil falls on them.
1.5 13w01a Redstone torches are used to craft redstone comparators and activator rails.
1.7.2 13w37a The item form of block ID 75 (inactive redstone torch) was removed from the game. It can no longer exist in inventories, only as a block in the world.
1.8 14w07a Redstone Wall Torch.png Redstone torches attached to the wall are now simply rotated versions of upright redstone torches, rather than having their own block model.

1.9 15w43a A redstone torch generates as part of igloos.
1.13 17w47a The different block IDs have been split up and merged into redstone_torch for on the ground, and redstone_wall_torch for on a wall.
Added lit block state.
Prior to The Flattening, these blocks' numeral IDs were 75 and 76.
