Keyboard for CX-52 - this page is a stub

B-62 is a keyboard add-on for the Hagelin C-52 and CX-52 cipher machines, introduced in 1962 by Crypto AG (Hagelin) in Zug (Switzerland) as the successor to the B-52. The device converts the manually operated one-letter-at-a-time C(X)-52 into a motor-driven cipher machine, on which text can be entered like on a typewriter. This is different from earlier machines like the M-209 and C-446, of which keyboard-versions like the BC-38 and BC-543 were available. Using a separate keyboard unit makes it much more versatile. Different version were available, such as the B-621, B-621a and B-621b. The combination of C(X)-52 and B-62 was known as BC(X)-62.
