brake lights not coming on

I was driving my '47 Super 8 home the other day after getting the engine rebuilt, and I noticed at one point that my brake lights were not operating. This happened several years ago on a cruise and a friend replaced the brake light switch in the parking lot of the hotel -- easy. This time around I did it in my garage, using the spare I had bought after we got home from our vacation and this one failed also. Could this be another bad switch or is there a fuse somewhere that I don't know about? Also, the bleeder screws are absolutely welded shut and I've soaked them with PB Blaster to try and turn them to bleed the system, even thought I was careful not to introduce any air into the master cylinder while reinstalling the new switch and I do have brake pressure with no soft pedal. Am wondering if there is an unfortunate air bubble that is preventing the switch from activating, but I have never had this issue with any other car after a swap-out of this switch. Any ideas?
