Well first of all, make sure that your foot is all the way to the floor, as far as it can possibly go. I know that sounds simple, but I've made that mistake where I was just far enough off for the switch not to contact. Then check under your dash and make sure that the clutch pedal is contacting the switch, and making it go in all the way. If it is, test the switch with a continuity tester. Unplug it and put a probe on either side of the switch. The needle type probes help for this.. Push the switch manually, and it should indicate continuity, and then no continuity when you let go. Just by doing that, I would guess that you will find the problem. If not, let us know.
