Turnover Positions
In this table the turnover point of each rotor is listed. For more details on how the rotors move, please check the Stepping motion section and the remarks on double-stepping in the Enigma article.
| Rotor | Notch | Effect |
|---|---|---|
| I | Q | If rotor steps from Q to R, the next rotor is advanced |
| II | E | If rotor steps from E to F, the next rotor is advanced |
| III | V | If rotor steps from V to W, the next rotor is advanced |
| IV | J | If rotor steps from J to K, the next rotor is advanced |
| V | Z | If rotor steps from Z to A, the next rotor is advanced |
| VI, VII, VIII | Z+M | if rotor steps from Z to A, or from M to N the next rotor is advanced |

Famous quotes containing the word positions:
“The season developed and matured. Another year’s installment of flowers, leaves, nightingales, thrushes, finches, and such ephemeral creatures, took up their positions where only a year ago others had stood in their place when these were nothing more than germs and inorganic particles. Rays from the sunrise drew forth the buds and stretched them into long stalks, lifted up sap in noiseless streams, opened petals, and sucked out scents in invisible jets and breathings.”
—Thomas Hardy (1840–1928)
