I had the same problem with the switch, put a dent in my finger to the point of pain! LOL
I also had a problem with it sticking under the edge of the box, got real tired of that real fast! So, I took my exacto knife out (VERY careful not to hurt my box) and rounded the edge out in the direction the switch flows and WA LA, it works great now! Barely have to push it, I think it was hitting the edge of the box causing you to need to push harder to make contact. You can't even tell it was modified if you're very careful to just shave off the slightest bit in a circular motion.
