Retractable Block

The retractable block is an electronic device which moves from the background to the foreground (solid) when it receives a HIGH signal.
If a player is standing in front of the block when it is activated they will automatically jump to the top, just like when you place a block on yourself, this makes these useful for elevators among other things.
Copper Wire, Levers, or other devices can be attached to any side.
