Crypto AG HX-63 Cipher Machine Rotors

The HX-63 was an electromechanical rotor-based cipher machine, introduced in 1964 by Crypto AG in Zug (Switzerland). Each of the HX-63's nine main rotors are connected via a set of 41 gold-plated contacts allowing electrical current to flow through the rotor assembly.
