How do I remove the excess wires from this 2/3 way lighting switch?

Question

I have two sets of lights in my bedroom. There are also two light switches. One double light switch is by one door, and turns both sets of lights on or off (one switch does one set, one does the other).

There is also another light switch near the bed - this is a single light switch. It turns on and off one of the sets of lights regardless of how the double switches are set. I gather that this is either a 2-way (UK, where I am) or a 3-way (US) lighting system.

I am going to be replacing the double switch near the door with some relays so that I can control them over the internet. I don't really use the other switch, and I want to do away with it for simplicity's sake. There are pictures of the light switch and a rather crude diagram of what it looks like from the back attached. Which one of those wires is dispensable?

Bonus points if anyone can provide a schematic for this kind of set-up. I'd like to know how it works.

Answer 1

You would require something along these lines where SW1 is the switch by your bed:

The research that you would need to do is: can you drive relays with the GPIO of a microcontroller (I think probably not).

Answer 2

I don't understand why you want to get rid of the light switch and replace with relays but I can offer clarification of how your switches work:

The SPDT switches on the left of the diagram that I have drawn make up the six terminals that you have on the light switch by your door and the third is the switch by your bed.

If you could explain what you are hoping to achieve I may be able to help further.
