This is what I recommend: Replace the switch then try resetting the circuit breaker; if that doesn't fix your problem you'll probably looking at tracing the conductors back to a point where they may be tapped and check connections there.
While it is hard to tell you steps to take here, trouble shooting electrical problems begins with tracing the circuit and checking along the way for power until you arrive at a point where you have power in but no power out which is indicative of a bad tap.
Good luck and always be extremely careful working with electricity.
