67 Dart 270 reverse lights always on...help please

Any update?
Soooo....life got in the way lately but today I managed to locate the reverse light switch and remove it. Went through the gears and watched the operating lever at the base of the steering column move freely. Manually operated the switch lever and its able to move all the way through its range of motion but hangs up in the spot that obviously closes the circuit, hence my "always on" reverse lights. With a nudge it will move past that spot and the circuit opens and reverse lights go off as intended. It feels like it's just gunked up but def could be some internal switch bits faulty as mentioned by some of you guys with switch issues of your own.
Is there anything safe to spray in the switch to see if it could be lubricated to get that lever moving freely? Would like to try all available options before having to buy one as they are pricey.
Thanks again for the previous posts, the info made locating, removing, and troubleshooting fairly simple.
