Klappenschrank
A Klappenschrank was a piece of equipment in the early days of the telephone, that was used to connect two subscribers with each other.
It was operated by a Fräulein vom Amt and was effectively a board made up of holes – one hole per line, covered with a small cap. The caps would flap to show that someone wanted to make a phone call, and often a light bulb would show that a line was still in use. Two holes would be connected by a wire to establish the call between the two parties.
They stopped being used on the telephone network in the western German states in 1966, and in the GDR in 1987.
