Not necessarily electrical in nature but concerning the turn signal switch itself. I do a bunch of events every year that involve interfacing with the public like "Touch-a-Truck", Veterans Day, and other veteran support activities that have us opening up the trucks to the public to enjoy and learn about them and the one thing I worry about is the turn signal switch. 99.9% of these trucks are immune to public access but the one thing I worry about is the turn signal switch. Kids love to shift it around and I always worry about little fingers getting caught in it. Has anyone come up with a better solution that wrapping it with shrink wrap?
