Apologies in advance if this is the wrong SE to post this in, but Electrical Enginnering Stack Exchange didn't look like the proper place, based on what was 'on topic' over there.
Anyway, I have a power bar in my room, similar to the one pictured below, that has some sensitive electronics plugged into it. During thunder storms and the like, I turn the bar off using the little switch, and leave it plugged in, as accessing the plug is a little bit of a chore.
My question is, will turning the bar off at the switch prevent anything plugged into it from receiving a killing blow from a surge, should the power lines to the house get struck with lightning?
