Redstone Torch

A redstone torch is a non-solid block that can be used as a toggleable redstone power source, as well as a signal inverter.

Natural generation
Redstone torches can be found in igloos.

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

A redstone torch is removed and drops itself as an item if:
 * its attachment block is moved, removed, or destroyed
 * water or lava flows into its space
 * a piston tries to push it or moves a block into its space

The inactive redstone torch cannot be obtained as an item. In Bedrock Edition, it can be obtained via inventory editing.

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

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

Redstone component
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


 * To place a redstone torch, use the control while aiming at the surface to which the redstone torch should be attached.


 * A redstone torch can be attached to:
 * the top or side of any full solid opaque block (stone, dirt, blocks of gold, etc.), including full-block mechanism components (command blocks, dispensers, droppers, note blocks, and redstone lamps)
 * the top only or side only of certain block. SeeOpacity/Placement.


 * 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 causes 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, hoppers, and stairs cannot be powered so redstone torches attached to them cannot be deactivated.


 * A redstone torch takes 1 redstone tick (2 game ticks, or 0.1 seconds barring lag) to change state and usually does not respond to 1-tick fluctuations of power.


 * Behavior


 * While active, a redstone torch:
 * powers adjacent redstone dust to power level 15, including beneath the redstone torch if it is attached to the side of a block
 * powers adjacent redstone comparators or redstone repeaters facing away from the redstone torch to power level 15
 * strongly powers a full solid opaque block above the redstone torch to power level 15 (but not next to or below it)
 * activates adjacent mechanism components, including above or below, such as pistons, redstone lamps, etc.
 * produces "reddust" particles


 * 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 does not activate the lamp.


 * A redstone torch experiences "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 produces a "smoke" particle and a hiss similar to an extinguished fire, deactivates, and then ignores 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 re-activates when it receives a block update (an adjacent block changing its state) or a redstone update that wouldn't normally deactivate the redstone torch. There is no limit on how often a single redstone torch can burn out.

In Bedrock Edition, a redstone torch's block data specifies its orientation.
