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. The torch can only power the wire for a length of 15 blocks.

When put on the side of another block, it behaves like a 5-input nor gate - it only turns on if there is no electricity on any other side of the block (the bottom can only be activated by another cuprite torch). As is true about logic gates, this allows the flow of electricity in only one direction, so putting two in a row is a good way of not allowing any electricity to pass backwards.

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 recommended because it has only a third of a regular torch's light output and the cuprite is much harder to find than coal.
