Please make sure the battery is fully charged before doing this test! Also make sure all the connections on the starter, battery and cable ends are tight and clean! this is important!!
This won't be fun to test but it will tell you if the starter is good or not. Crawl under the car. (Make sure you use the proper jacks and jack stands!) find the end of the starter (not the end that is attached to the bell housing) and find the solenoid switch. it should have 3 bolts on it. Two large ones and a small one. The top large wire should be the positive battery cable, the bottom large wire should go into the starter and the small wire should be from the ignition switch. Take a wire and hold it to the top large wire on the solenoid. (be careful of the other end of that wire when you have it connected to the top large wire of the solenoid! don't ground this wire. it will turn out badly. don't ask me how I know this is true!) take the other end of the wire and touch it to the small bolt on the solenoid end. If the starter is working, the solenoid should engage and the starter will turn. If this happens it is most likely the ignition switch. If the starter doesn't turn, the starter could be bad.
Defective Starter solenoid or ignition switch. Ignition switch is bad.
It sends a power to the starter relay/solenoid to engauge the starter. Know that the ignition switch is not what you put the key in and turn. That is the lock assembly. The ignition switch is located lower down on the steering column.
You have a starter/ignition switch mounted in the steering column and you have a starter solenoid switch that is mounted to the starter.

are all the connection plug in on the switch and did you have fire before replaceing switch
It will not engage and send current to the starter. You will not hear a click or anything else if the ignition switch is bad. With your headlights on when you turn the ignition if the lights dim is it not the ignition switch but more than likely a bad starter. If the lights do not dim it is more than likely the ignition switch.
Probably not a bad ignition switch, but more likely a bad starter solenoid. It takes a lot of current to get a starter to turn, to much to go through such a small switch like the ignition switch. The ignition switch actually controls a relay(solenoid) which can handle the needed current to get the starter going. On a lot of modern cars the solenoid is built into the starter unlike older cars and trucks where it was mounted on the firewall between the battery and the starter.
This could be a bad ignition switch, ignition relay, or ignition fuse.

might be starter relay, or the crank circuitry from the switch or to the starter from the relay. I would trace back from the starter to the starter relay back through the neutral safety switch to the ignition switch.
