Wiring question, swapping out a switch for a dimmer. The
electricians cowboys that fitted out our house have used the following wires to wire in the switch, (they've nearly killed me twice so I'm allowed to call them that).
Old switch is labelled up as follows on the back
Yellow - Common
Blue - 1 way
Red - 2 way
Yellow and red have red tape on them, suggesting they're the live wires.
New switch has L1, Common, L2
So I'm thinking
L1 - Blue
Common - Yellow
L2 - Red
It seems obvious enough but the fact the yellow has red tape on it is making me second guess myself.
Any advice appreciated.
