Have you checked continuity between terminals in the various switch positions? Not knowing anything more about it, it sounds like an SPDT (single-pole, double-throw) switch, in which case *probably* the center terminal goes to hot, and two outside terminals go to two different loads, with center position off. Or it could be wired to two different hots, with the center terminal going to the load. None of the main terminals would usually be wired to ground -- I suspect that you're connecting your hot directly to ground through the switch, which certainly *ought* to blow the fuse. The two small terminals as you said are probably for a pilot light. But a few minutes with an ohmmeter between all combinations of terminals in all switch positions should sort out what's going on.
