  NEMA
NEMA also has a detachable external lampboard which is stored in the lid of the case along with its cable [about 90 cm in length].
To use the machine for encipherment or decipherment the operator must first remove the nine removable wheels from the machine on their central spindle - the red-coloured control wheel on the right is not normally removed from NEMA during this procedure.
NEMA is not yet as 'collectible' an item as Enigma and the cost of acquiring one reflects this - being of the order of one tenth or less.

 NEMA (machine) - Wikipedia, the free encyclopedia
NEMA uses 10 wheels, of which one is a reflector, four are normal rotors, and the remaining five are "Drive wheels", which control the stepping of the rotors and the reflector.
NEMA was declassified on 9 July 1992, and machines were offered for sale to the public on 4 May 1994.

Their machine was called NEMA (NEue MAschine) and the first working examples were not ready until 1945.
In principle, the NEMA machine worked like the Enigma, but it had 10 rotors (arranged to work as 4 pairs of 2), a reflector rotor, a special "red" rotor but lacked the plugboard.
There were two variants of the NEMA machine - a 'training' model and a 'service or military' model, both of which were incompatible with each other.

NEMA ratings are standards that are useful in defining the types of environments in which an electrical enclosure can be used.
NEMA ratings are rarely applied to mobile devices, and are mainly applied to fixed enclosures.
NEMA ratings have more stringent testing requirements to verify protection from external ice, corrosive materials, oil immersion, dust, water, etc. These stringent testing requirements can rarely be applied to mobile devices, but there is a correlation between NEMA ratings and IP ratings.

 Grand Illusions - Toy Shop - Nema Machine
The machine looks similar to a typewriter, but when you press a key, the letter you have typed is immediately encrypted into another letter - a letter will light up on the light board, which is above the keyboard.
However the electrical circuit that is created to cause the light to go on passes through a system of rotors, and after every key stroke, at least one of the rotors rotates, so if you were to press the same letter a second time, it would now encrypt as a different letter.
The New Machine or NEue MAschine, was first available in 1945, and they were used by the Swiss Army and Air Force from around 1947.
