Editing Enigma rotor details (section)

== Turnover notch positions ==
The single turnover notch positioned on the left side (plate connector side) of the rotor triggers the stepping motion by engaging the [[ratchet teeth]] of the wheel to the left. Later rotors had two turnover notches. The table below lists the turnover notch point of each rotor.

=== Normalized Enigma sequences ===
In the following examples you can observe a normal step sequence and a double step sequence. The used rotors are (from left to right) I, II, III, with turnovers on {{mono|Q}}, {{mono|E}} and {{mono|V}}. It is the right rotor's behavior we observe here (turnover {{mono|V}}).

:''Normal sequence:''

* {{mono|AAU}}  &mdash; normal step of right rotor
* {{mono|AAV}}  &mdash; right rotor (III) goes in V&mdash;notch position
* {{mono|ABW}}  &mdash; right rotor takes middle rotor one step further
* {{mono|ABX}}  &mdash; normal step of right rotor

:''Double step sequence:''
* {{mono|ADU}}  &mdash; normal step of right rotor
* {{mono|ADV}}  &mdash; right rotor (III) goes in V&mdash;notch position
* {{mono|AEW}}  &mdash; right rotor steps, takes middle rotor (II) one step further, which is now in its own E&mdash;notch position
* {{mono|BFX}}  &mdash; normal step of right rotor, double step of middle rotor, normal step of left rotor
* {{mono|BFY}}  &mdash; normal step of right rotor
