Need help with Brake Switch!!

For some on my 93 T-bird, the only way to get my brake lights to turn on is to push the brake pedal all the way to the floor. I have brake fluid in it and my brake pads are fine. I am guessing it has something to do with the switch a little ways up from the brake pedal. I have no idea how to adjust it or if it need to be replaced. Any help with be appreciated

As far as I know their is no adjustment that can be made. Mine went bad and the switch only costs about 10$. And it only took me 5 minutes to replace it.

Got my switch from the junkyard.It's square looking.
Although my lights didn't work at all.It hooks
about half way up the brake arm.Fairly easy to change.
