How it works

Compare a lever merely beside a block with dust pointing into a block. Both power relationships look similar, but only the second puts out its attached torch in these layouts.

  1. A solid block can receive power in different ways.
  2. The source type, receiving face, and nearby components decide which neighbors can read that power.

Inputs and outputs

  • Inputadjacent lever (x 0, y 0, z 0)
  • Inputlever through dust (x 0, y 0, z 3)
  • Outputfirst torch (x 3, y 0, z 0)
  • Outputsecond torch (x 4, y 0, z 3)

Blocks you need

3 × redstone dust, 2 × lever, 2 × stone, 2 × redstone torch (on a wall).

Build it in the game: 9 commands

Relative to where you stand, with x running east and z running south. Paste one line at a time into chat, or into a chain of command blocks. The block art is the game's own; the layout is what the page above shows.
