Redstone Torch

The Cuprite Torch is an item which is used as a power source for wires and as a result can be used to sabotage/activate traps and get into locked iron doors making it useful for raiding parties in multiplayer. Wires in turn are used to operate a Stone Button, a Lever, or a Pressure Plate from a distance. It turns off when any adjacent switch, lever, or pressure plate is turned off. The torch can only power the wire for a length of 15 blocks.

The Cuprite Torch will constantly power a set of wires, and is used as a "block-based" switch sometimes. Using it as a source of light is not reccommended because it has only a third of a regular torch's light output.
