[Amps] [BULK] - DIN stands for....?

[Bill NY9H]

that DIN plug....

Ten Years ago when I was representing ( among others)  the Preh 
company, we sold many "din" connectors of all varieties.

As part of the "indoctrination" about the company we were told that 
Dr. Preh was the one who was responsible for the Din plug.  They 
liked to take credit for that.
  Preh maintained stock of most of this in Lake Zurich , IL ( US HQ)....

Thanks a lot Dr. Preh !!!!
