I am trying to replace one metal dimmer switch for another as the switch in the kitchen that had just stopped working - all other lights working fine on the circuit.
It's more a less a swap of identical dimmer switches i.e. a switch with L1, L2 and Common with a green/yellow earth for another of the same.
Coming into the back were two red wires, which I am 99% sure were both going into L1, with the blue into common, and earthed. By the time I took the screw out holding the red wires in, the exposed copper of one wasn't long enough to work with in the new switch - the "end" was still inside the contacts
What I don't understand is the kitchen should only be a 1-way switch as far as I can tell, but why is there one blue, but 2 reds? So I have tried putting the wires back as they were - 2 reds in L1, blue in common, earth connect but this trips the fuse?
