Dandy. Happy to hear you found it, but you need to go further. Those blackened terminals must be replaced. They have lost their tension, and along with the arced areas, that will create resistance which translates to heat when current flows through the connection. That heat will migrate into the switch and degrade the new contacts. Normally there's only two terminals that get overheated. They can be cut out of the melted plastic body, then new ones can be plugged in individually. You can use crimp-on terminals but solder them too for a better connection.
You'll also see about 4" of those wires are hardened from being overheated. They'll be stiff and hard to bend. Solder won't adhere to them. Cut that 4" off, then splice on a new piece the same gauge. I like to push the strands into each other, then I solder them and seal the connection with heat-shrink tubing. Never use electrical tape. It will unravel into a gooey mess on a hot day. Be sure there's no sharp points of wire sticking up before you heat the shrink tubing. An end of a wire can poke through and cause a short.
Please consider a to help us answer more questions.
