As the closest bead of light moved nearer to Harry's wand tip, the wood beneath his fingers grew so hot he feared it would burst into flame. The closer that bead moved, the harder Harry's wand vibrated; he was sure his wand would not survive contact with it; it felt as though it was about to shatter under his fingers -
I guess "survive contact with" here means his wand would be broken/shattered once contacting with the bead. I'm wondering if "survive contact with" is a set phrase? The closest one I got: no plan survives contact with the enemy. It might be slightly different. I'd also like to know what part of speech "contact" is, noun or verb?
