Yes as cooperman says, and Richard V6 a short while ago too.... check out the marine versions as they are far better quality! That's if you go down the isolation switch route. Must be honest, when I saw Richard's post I did feel confident in then fitting one but keep forgetting to get on and order it. When you consider the Halfordian price of the cheapies on offer they really can't be that good for anything other than an emergency shut off. I think Richard also offered an alternative way to isolate those electrical areas which are problematic yet those areas which need to remain functional were left as is! Perhaps Richard will reply here as I might be talking gonad's!

Something I would like an answer to is how PCB's and some components degrade if not regularly used. My wife's sowing machine, A Bernina, was taken out the other day and failed to work. Now this is an expensive machine with a sales slogan of " you'll never need to buy another sowing machine" and "The best in the world" etc. So, we take it into the repair centre and it's in there for three months waiting its turn. We then get a call saying "Oh we don't have the replacement boards for those anymore you'll have to buy a new machine. What you have done wrong is to not use it enough, you need to switch them on for at least an hour a week even if you are not using it so its your fault! They need using in order to protect the boards, Funny that, that's not what the gas boiler service dept. said re. the boiler PCB.... the exact opposite in fact! "Oh they're on all the time so just fail".... me thinks cheap crap from foreign climes!
