Wasn't sure where to post this question, so trying it here. The cowcatcher on this locomotive touches the screw terminal on the switch track, which causes the track to switch and of course derail the train. Is there any way to stop this from occurring? It hits the screw, not the wire terminal.

Is your track code 83?
How hard does it bump? Does it bump on every switch?
Option let it bump and eliminate the electrical connection; a piece of tape or a dab of paint, CA or epoxy. Or a separate power transformer independent from the track power.
Option remove the screw: jam some bare wire into the screw hole and hope it stays. Or solder.
Option lower the screw head: file screw head. Perhaps if you feel desperate and lucky heat the screw until the plastic is soft enough to allow the screw assembly to be pressed down.
Fun and games!

some switches allow you to increase the distance from the rails to the electrical connections to avoid this

had to do it once to a whole layout specifically for this loco

Although you say the locomotive is hitting the screw and not the wire lug, the lug is the problem. It rsises the screw up just enough to hit the locomotive. I am assuming the cowcatcher is metal, and it's shorting when it hits the screw? The solution is simple. Remove the terminal lug on that particular wire, and wrap the wire end aroound the screw post. When you tighten it down, the screw should be low enough not to interfere. Those switch motors are designed to clear everything is installed as designed. When you added that wire lug you deviated from that design and unintentionally caused the problem.
