Took the headlight s/w out to clean it, remove the deteriorated wiring and un-solder the terminals.
.
I tested it, and it worked fine, but was a little sticky after 80 years. To clean it the 4 tabs that hold the fiber board terminal panel in place have to be bent up. Any tips for minimizing breaking a tab off ? Also, what is suggested as a cleaner/lubricant for the switch mechanism inside.

I plan to solder male slide tabs for push-in wire connectors on to the existing switch terminals.
