Button

A button is a non-solid block which can provide temporary redstone power.

Obtaining
Buttons can be crafted from stone or wood planks, and stone buttons can be found in strongholds.

Natural generation
Stone buttons are generated naturally in strongholds next to iron doors.

Usage
A button can be used as a monostable power source (it will automatically deactivate shortly after being activated).


 * Placement


 * To place a button, use the "Use Item/Place Block" control (right-click, by default) while aiming at the surface to which it should be attached.


 * A button can be attached to the side of any full solid opaque block (stone, dirt, blocks of gold, etc.). In, buttons can also be attached to the tops and bottoms of blocks.


 * Activation


 * Buttons are usually in an inactive state, but can be temporarily activated by players. To activate a placed button, use the "Use Item/Place Block" control (right-click, by default). A wooden button can also be activated by a fired arrow.


 * Mobs cannot activate buttons directly, but arrows fired by skeletons or dispensers can activate wooden buttons.


 * Behavior


 * When activated, a stone button will remain active for 10 redstone ticks (1 second, barring lag), while a wooden button will remain active for 15 redstone ticks (1.5 seconds, barring lag). A wooden button activated by a fired arrow will remain active until the arrow despawns after one minute or is picked up.


 * While active, a button:
 * powers any adjacent redstone dust to power level 15, including beneath the button
 * powers any adjacent redstone comparators or redstone repeaters facing away from the button to power level 15
 * strongly powers its attachment block to power level 15
 * activates any adjacent mechanism components, including above or below, such as pistons, redstone lamps, etc.


 * Removal


 * To remove a button, use the "Attack/Destroy" control (left-click, by default). Removing a button takes 0.75 seconds and it will drop itself as an item.


 * A button 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


 * A button will be destroyed without dropping itself as an item if lava flows into its space.

History
The pre-1.4.2 crafting recipe for the stone button required two stone blocks:
