Few weeks back my brake lights stopped working. I pulled the switch on the brake peddle and tested it with an meter finding that it was the problem. After looking up the replacement cost, I tried the meter again just to make sure. Worked intermittently. I snapped the lever a few times and woola. It worked. Maybe there was some dirt in there blocking the connection. Checked multiple times and it always worked. I reinstalled it and everything’s fine.
As you noted, mechanical switches can get dirty, arced over, and oxidized and stop working or working intermittently. When you do the exercising of the switch it's also very helpful if contact cleaner is sprayed into the switch. Drown that thing in cleaner.
its a good place to start, i will get home tomorrow, and pull the switch and test it. its not as easy as suggested when you have a center console in the way. i dont see anywhere that the the wire would be pinched and the connection to switch are tight. The little lever that moves with brake pedal moves freely. since i checked the grounds and the fuses, and bulbs check out good too, it looks like the switch is most likely culprit. i ordered a new one from sierra m. just in case.
