A bit of digging turned up the lift/elevator call station that I salvaged at the same time as its control panel. It's super-robust inside and completely serviceable as most equipment from that era was.
The large amount of bare live metalwork was also quite typical of that era, making working on these call plates potentially somewhat more violent than their modern low voltage CAN-Bus (power and data) equivalent.

The larger floor 1 contact, couldn't that be because floor 1 would probably get twice as much use as 2 or 3?
Maybe they realized that floor 1 was wearing out much sooner than the other floors.
That cast enclosure is serious overkill…
My guess is that the controller does not have a means to decide where to go first, and probably goes into a fault condition, hence the interlocking on the call station. However, in the previous slate controller video, I saw that the memory relays had normally closed contacts, and those could serve as interlocks as well. Maybe it is another layer of protection?
Beautiful old panel! Made with care and not so much concern for the bottom line!
There is more metal in that switch box than in a modern car!
Apart from the obvious to think your looking at someone else's thoughts from the past in 'solid form' is amazing, wonder who they were.
You should restore these and make cool contraptions and switches with them! Imagine what you could do with this, and what you could do with the solid slate panel!
That's a work of art! Crazy how durable that stuff was compared to modern flimsy switches.
I assume the wiring was replaced at some point, since it was probably all cloth covered originally?
I really appreciate that kind of engineering/technology. KISS at its best, who needs microprocessors and touch screens.
I imagine the hands that assembled that will have long left us sadly. Little did he/she know their handy work would be shown to the world one day. I love old technology.
The looping protected the motor. You don't want 3P motors getting both feed directions at once. Boom.
The kind of thing what will still be working long after the universes heat death
looks like it was manufactured in the early 30's, mabye by evans or express?
I don't think its a call station. I think its a in-car station for a 3 floor elevator, because it provides a stop button in addition, and as theres 3 button.
