Here is another one of my "Know you have see it before but cant id" series.
The buttons closest to you i.e the first row are marked with "N1, N2, M, 0, _ , I, I, I, I, 0, I, Operator"
I have checked with experts in phone equipment collecting and they said they have never seen the switches. Because it says Operator I thought it might be phone company related but I have found nothing similar. The "I" switches look so familiar I just can't place them. I even thought they might be elevator control switches but cant find a likeness.
Suggestions.
