Editing Enigma rotor details (section)

==Rotor wiring tables==
This table shows how the internal wiring connects the right side of the rotor (with the spring-loaded contacts) to the left side. Each rotor is a simple substitution cipher. The letters are listed as connected to alphabet order. If the first letter of a rotor is {{mono|E}}, this means that the {{mono|A}} is wired to the {{mono|E}}. This does not mean that {{mono|E}} is wired to {{mono|A}}; such looped wiring is only the case with the reflectors.

;Terminology
*''The reflector is also known as the reversing drum or, from the German, the Umkehrwalze or UKW.''

Technical comments related to Enigma modifications 1939-1945.

=== Swiss K ===
In 1941 it became known to the Swiss that some of their Enigma traffic was being read by the French. It was decided to make some design modifications.
* One of the modifications consisted in modifying the wheel stepping on the Swiss Army machine. The slow, left-hand wheel was made stationary during operation while the second wheel stepped with every key stroke.
* The third wheel and the UKW would step in the normal fashion with Enigma stepping for the third wheel.
* The stationary but rotatable left-hand wheel was meant to make up for the missing stecker connections on the commercial machine.
Swiss Army Enigma machines were the only machines modified. The surviving Swiss Air Force machines do not show any signs of  modification. Machines used by the diplomatic service apparently were not altered either.
