Button

A Stone Button is a block that was introduced in the Seecret Friday Update 3. It has the same texture as a block of Stone. A button can be mined easily with the player's hands.

The Stone Button appears in Alpha and Beta. It can be crafted by placing two Stone blocks in a vertical row. Like Levers and Pressure Plates, it sends a charge to an object when pressed. However, a button can only be activated by being pressed and will only stay pressed for .9 seconds. After this, the charge to the object will be lost and the button will pop out, ready to be clicked again. 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.

The stone button is one of three Switches currently in the game. As a momentary-contact switch, it can be useful for resetting redstone circuits.

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

Also like torches, stone buttons can be placed to a side of a chest, dispenser, workbench, or furnace in the same fashion. This is done by placing a solid block above the area the button will attach to, 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.
