I am haveing problems wireing up a dimmer switch,
on removeing the old switch i found that all the blue wires have been joined together, there was 2 brown wires in L1 on one side of the switches which has a link wire across to L1 on the second switch.
There is one brown wire out of each of the L2 terminals, the eath wire is into the earth terminal.
I wired up the new switch the same way but non of the lights work!!
What am i doing wrong???
