Any Help appreciated! Bake element melted.

My bake element caught fire and melted. I bought a new one and replaced it; however, my lower and upper(broiler) still don’t work. I am guessing it caused a fault when it melted and blew a relay somewhere. I attached a PDF of the wiring diagram. I traced the left (looking at the back of the range) wire from the side of the element, which melted to the left side of the OUTER SW…whatever that is?! Can this be replaced, or do I have to buy the whole thermo assembly? I do have a voltage meter, but got nervous about the whole 240 volt scenario…help!!!
