brake light switch mounting?

Thanks for the responses guys. It WAS out of adjustment, but the bolt was tight (can't figure out how that happened). I loosened it, moved it up to where it should have been touching the pedal, and noticed it was about half an inch too far to the right!

It turned out the bracket was slightly bent, after all. Something must have really yanked up hard on the brake pedal to bend that bracket and shove it out of position witih the bolt tight like it was. I had it towed the last time it killed over on me on the interstate, and prior to that, the brake lights worked fine. I wonder if the tow-truck driver did it somehow? I have no idea how or why, but whatever...it's fixed now. Thanks again!
