Is it a trick of the light, or is that black wire not actually connected to A1?
I gather switch A is 2-way for an indoor light.
In which case switch B is for this light. All wired ok (apart from earths).
Unless someone has made a hideous attempt to switch live and neutral.
<BOOM>
Tomorrow I fit plastic switches throughout the house
Well spotted.The problem is obvious - with both the light and the switch you've forgotten the screws - neither are supposed to be dangling like that.
Anyone local to Whitehaven, want to do the check?
Are the earths provided by steel conduit?
