Hi,

Good question. I planned to document it but never did :(. I might have it somewhere for photos at least. I do check.

I found it but this project was cannibalized to other system. However I found similar ready made system which does exactly the same and is cheap. This is Pololu RC switch with relay: https://www.pololu.com/product/2805

Principle was to close or open one contact but I can't remember which way. Anyway this Pololu offers both NC and NO contacts.

Here you see which contacts were connected to relay in my board. Green (middle contact) was left open and wasn't in use:
