2 Way Switch help! One switch immobilises the other

[telectrix]

I take your point to a degree. I have always done everything for myself, and of course it should be encouraged. Thing is, not everyone is up to it? If this scenario was the brakes on a car/bike then would we be so full of admiration? It is a dangerous thing in the wrong hands when all is said and done, some of the clueless souls on here (I am not pointing the finger at this guy in particular) make your eyes water, and I have to question sometimes if it should be encouraged. Where do we draw the line? It's OK saying "it's just a light switch" but, apparently, lighting circuits are responsible for the majority of domestic shock incidents.

agree, but where do you draw the line? some DIYers are capable of more than others. some are just oxygen wasters.
