Confusing wiring

Confusing wiring

Can somebody please help me with what is happening with these 2 switches. I am wanting to replace these 2 switches with 2 new 2 gang (2 switches on one plate) switches and the wiring and colour coding makes no sense. 4 Lighting circuits all with multiple lights.

Many Thanks


John

OK.

Far bottom left - that red and black is a live strapper pair to another switch. I should be right in assuming that switch is paired with another that controls the same light.

The top red wire (short link one) is the permenant live to the switch. The switched live is taken off at the other switch elsewhere in the room/house.

The right switch on the left plate is a single way controlled light - there is no other switch that controls the same light. The reds there are permenant live and the black is switched live.

Now, the right plate is a little more tricky. If I assume the top middle terminal is empty (it must be to work right), red is permenant live throughout, and the blue and yellow are switched lives to two switches. Again, these switches are on their own, singly controlling two lights on their own.

You wont go wrong, if you remember that for each switch there is a triangle of terminls on the back.
