__NOTOC__ __NOEDITSECTION__
==Description (from [[Recipaedia]])==
''Pistons can be used to push and pull blocks. The extention of piston is controlled by voltage applied to it. 0.8 v will extend piston 1 block, 0.9 v two, etc.1.5V will extend a piston a maximum of 8 blocks. Pistons can also be edited to limit the maximum extention to lower values. 
If the piston is a pull piston it will also pull one block back when retracting. If the piston is a strick pull piston, it will not pull back unless it is pulling back a block.''

This is the strict pull piston which does not pull back unless there are the proper amount of blocks attached to it.

== Crafting ==
It takes 1 [[Copper Ingot]] and a [[Piston]] to craft 1 strict-pull piston.

</div>

NOTE: The plain piston must be reset to its starting settings or the crafting table will not accept it. That is, the max extention must be 8 and the speed must be fast.

==Use==
Place the piston where you want it. It is a directional block like the [[Dispenser]] and will be aimed at you when you place it.

This piston is a special case and can be very useful in a wide variety of applications. It is necessary to make compact [[Piston Lifts]]. With this piston, some very complex machines may be designed. 

You can think of it as having a 'block detector' built into it. Once extended, it will not retract until the proper number of blocks is in-line. It can detect if a sand-fall trap has been triggered when placed carefully. It can even be used in mining to tell if there's an open space beyond a cave wall (within 8 blocks).


===Editing it===
Open its UI by making it center in the screen when you are close enough. The sneak button will turn into the edit icon (sheet paper). Tap that icon. The following window opens up:
<div style="overflow:hidden">

</div>

From this window you can adjust the piston's speed, the maximum distance it will extend trying to touch a block and the maximum number of blocks it will pull back.
