Lever

A lever is a non-solid block which provides switchable redstone power.

Obtaining
Levers can be crafted from sticks and cobblestone, and generate naturally in jungle temples.

Natural Generation
Three levers can be looted from each naturally-generated jungle temple.

Usage


A lever can be attached to the top, side, or bottom of most opaque blocks, or to the top of an upside-down slab or upside-down stairs. If the attachment block is removed, the lever will drop itself as an item.

When placed on the side of blocks, down is on and up is off. On the top or bottom of blocks, on is north or west, off is south or east.

To turn a lever on or off, right-click the lever. A lever can be turned on and off as fast as it can be clicked.

While off, a lever provides no redstone power. While on, a lever and its attachment block (unless attached to a slab or stairs) both power any adjacent redstone dust (including beneath the lever, or beneath or on top of the block), and any adjacent redstone comparator or redstone repeater facing away from them, to power level 15. They also activate any adjacent mechanism components (including above or below).

Mobs cannot turn a lever on or off.

Trivia

 * The lever, along with wall mounted torches, flowing lava and water, sloped rails, tripwire hook, Spider legs, Snow Golem arms, and Villager arms are the only surfaces in Minecraft that are not either parallel or perpendicular to the ground.
 * In version 1.6.1 and before the orientation of levers when placing on the top or bottom sides of blocks is determined by the direction the player is facing, just like with Beds, Chests, Signs, Furnaces, Heads, Anvils, Stairs, Pumpkins, Doors, Fence Gates, Pistons, Dispensers, Droppers, Repeaters and Comparators.
