I'm looking for a wiring diagram or some information about the internal connections of this switch from the blue train era.
It is used for controlling the automatic points, and is visible on the original box:
The points connect to the back of the switch using a 3-pole connector:
I want to use a microcontroller to operate the points without manually pushing buttons. Since I don't have any of these, I cannot measure the connections (using a multimeter).
Does anyone own this switch, and cares to share some information?
This is how I think the switch works. I have tried wiring it this way and it works, however the points barely move. Perhaps the problem lies with the solenoids inside the points?
