05 Mercury Montego-parking brake issue

Another freaking problem on this car.

I disengaged the parking brake today but the dash still reads "PARKING BRAKE ENGAGED". Attempting to drive anywhere results in the car making frenzied beeps. Also, I can't reengage the parking brake. If I press the pedal down it won't catch and will just return to the released position. I've checked and the parking brake is most certainly NOT on. The car will roll freely and when I press the parking brake pedal down it will stop so the brakes themselves seem to be working just fine which leads me to believe something is wrong with the pedal.

Any ideas?

EDIT:
I looked on the pulley behind the parking brake pedal and found some kind of plastic switch. I was able to flip it and this caused "PARKING BRAKE ENGAGED" light to go off and I was able to drive the car with no beeping. Doing this also allows me to engage the parking brake again, but once I disengage it the problem returns. So whatever this switch is called appears to be the problem here.

Any idea what the part number is? I can't find it listed on any of the car parts websites.

Also, from looking at this again it looks like the switch is part of the ratcheting mechanism on the pedal.

Thanks. It seems the only place that has it is "FordPartsGiant.com". It's a shame that they don't have any pictures of it so I could be sure it's the same thing I'm looking at on my car.

How would I go about replacing it? There's a ton of stuff in the way down there.

If you want to see the actual part before buying it, then go to your Ford dealer.

You might have to remove some trim, but you should be able to easily slip a wrench in there to remove the bolt holding the switch in. Remove it with the parking brake set slightly.

Alright, I checked out a picture of that particular part and it looks completely different from what I'm seeing on my car. The part I'm looking at is white plastic and is to the rear of the pulley for the parking brake pedal. It doesn't have any kind of electrical connections on it that I can see.

Is there any other part like what I'm describing that can go bad down there besides the parking brake switch?

Make sure the electrical connector didn't fall out. The switch is the only thing that would cause the parking brake warning to display. It's not wireless so there has to be some kind of wire.

Connector looks like this:
