sorry didnt knw wher to post this, but as its an electrical issue....

i opened the shower switch up as it jammed in the off position and had a funny fishy smell(cue funny comments....) coming from it....and found it 2 b melted,along with both neutrals

1 of the neutrals popped out very easily....
also the 1 of the live wires has a black burn strip running down it....
but the other live wire is ok...

my question is this....
could the melting of the wiring be caused by the switch heating up n melting, due to the loose connection, in turn leading to the melting of the wiring ?

its 2.5 mm twin and earth...so i would have thought its sufficient enough rite ?

any ideas ? as this is the second time this switch has burned out and im looking for a permanent fix

cheers
