Looking forward help please.
I am changing the switches on a 2 gang light circuit but I’m a little confused.
The existing switch says L1 (red wire) L2 (blue wire with a red sleeve) and L3 (yellow wire with a red sleeve)
The new switch says L-in Slave L-out
The existing switch says L1 (brown wire) L2 (blue wire with a brown sleeve) and L3 (brown wire)
The new switch says L1 Slave L
Can you please advise how I wire these in?
