Matthyro. it's good to hear that someone else is using the system.
If you look at the facia board in the general view of the backscene, you will see that there is a switch associated with each dowel.
I did try a sliding switch physically coupled to the dowel but it reduced the reliability of the system and made installation more tricky.
I don't have many points/turnouts on my layout, so i have not found the need for a cable.
By the way, a dowel will work at quite a considerable angle.
Thanks for the encouragement Rich.
By the way, a Metre is a touch under 39 and a half inches.
