Button

A button is a switch. Like levers, pressure plates, and tripwire hooks, it sends a redstone signal to adjacent blocks when pressed. However, a button can only be activated by being pressed and will only stay pressed for a short duration. After this, the charge to the object will be lost and the button will pop out, ready to be clicked again. However, with the creation of a T Flip-flop redstone circuit, it can be used as a lever substitute. Unlike levers and torches, a button can only be placed on the side of a block.

Like any object that gives charges, it must be next to the object receiving the charge (doors, rails, etc.) or connected to it by a length of redstone wire.

Properties
The button is one of five switches currently in the game. As a momentary-contact switch, it can be useful for resetting redstone circuits. The duration that a button is activated when pressed differs between button types, with stone buttons remaining active for 1 second (10 redstone ticks) and wooden buttons for 1.5 seconds (15 redstone ticks). Note that the wooden button can be shot by an arrow to become activated, unlike a stone button which must be physically pressed by hand, and they will stay pressed until the arrow despawns or is retrieved.

When submerged in water, Buttons are destroyed, rather than merely becoming unattached, like torches.

Also like torches, buttons can be placed to a side of a chest, dispenser, workbench, or furnace in the same fashion. This is done by placing any solid block above the one you want to place the button on, and right clicking it on the bottom with a button in hand. The button can't attach to the bottom of blocks, and will relocate to an available space. This lets you place the button on a block's side without right clicking it.

Mobs (excluding the player) cannot press buttons by hand, but skeletons may unintentionally trigger wooden buttons when firing arrows. Wooden buttons can also be triggered by arrows fired from a dispenser.

Natural occurrence
Stone buttons can be found naturally in Strongholds right next to iron doors.

Trivia

 * When sitting in a minecart and looking down at a slight angle at a button, sometimes you cannot press it even though it is in the crosshairs. This is caused by the hitbox of the minecart being larger than the minecart itself is, as with boats and many other entities.
 * Since buttons have the same texture as the blocks they are produced from, buttons can be placed on those blocks to make 'camouflaged' switches. However, despite this, buttons are popped out from the block in which they are attached to, therefore making this only useful if the subjects are directly across.
