I never went through and figured out which switches correspond to which doors. There are times you hit several switches in a row and never see the result; it's only when you hit a closed gate that you realize you missed one.
The best advice I can give is pull up the relevant map images and zoom in on them. (For you, it sounds like you'll need the second image after #14, and the image after #15) Every switch is marked with a light pink square, so reference the map as you go and you'll eventually find the switch you missed.
If I recall correctly: the floor tiles should simply depress into the ground, the wall switch graphic should show the handle pulled down, and the floor switch graphic should show the handle pointing to the right. There may also be a unique sound denoting the 'on' versus 'off' positions, I can't recall.
