for the schematic of what is going on.

Since this is an educational exercise you might like to know that there's a third way of wiring 2-way light switches but it should never be used:

You connect both L1 terminals to Live and both L2 terminals to Neutral. The light goes between the two COM terminals. Spot the stupid mistake!

Spot the stupid mistake!

The fact that you posted this in the first place???

If you use the third method, both feeds to the light should be sheathed red, as either side might be live. It was once common in counties with centre tap mains (2 phases with 220 between them rather than one L and one E )
Parts of Oostend used to be wired like this many moons ago, but the three phases of 135V, 220 between any pair has long since gone away to become 230V live, grounded neutral. (rather like DC mains in the UK, which was made AC between the wars.)
