Advice needed on two way switch

[wilkyduch]

Replacing a two way switch cover I’ve lost my note of the correct wiring on one of the switches.
Switch 1 has:
Grey to Common
Brown to L1
Black to L2
The wiring in place for Switch 2 has:
A single red wire
A yellow and red wire twisted together
A blue and black wire twisted together
My questions are:
Which colours go where in switch 2 And for interest, why does switch 1 have 3 wires and switch 2 a total of 5. What do the 2 additional wires do ? Why wouldn’t the colours in both switches match.
Thanks ever so much.

get the spark to do this at the same time as he repairs and checks the condition of your lighting circuit

Switch one look like it's the end part of a 2 way light circuit and Grey, is your common or LINE and the black and Brown are the strappers.

Switch two is Red Common/LINE with the Yellow and Blue as your strappers. The Red and black are from your light and go with the strappers.

The two different colours are RED/BLACK and RED/YELLOW/BLUE are pre colour harmonisation and maybe 7 years old. The BROWN/BLACK/GREY are the new colours.
