Nice demo setup - I note that with only one selector, it's naturally configured to behave as the 'final' selector, with the horizontal axis movement being controlled by the dial pulses for the final digit. As I recall, the behaviour of previous selectors would be different, with the vertical stepping being triggered by the subscriber's dial pulses for a digit, but the horizontal stepping being performed automatically, to find an unused line.
You are 100% right, Karl. I actually have another video on my channel showing the stepping of a groupselector: My vintage Strowger telephone exchange demonstrator, from 19:20 onwards.
There was a lot of resistance from female operators when automatic exchanges were introduced. Their jobs were taken away, of course. You see the same phenomenon these days when robots and artificial intelligence destroy jobs. But it will be unstoppable change.
Nu kan ik reageren, een prachtige demo weer, Wim.👍
Thank you! Very interesting technology!

It was quite an improvement when the human was removed from the process of making phone calls.
