Do you have an ammeter at the engine panel? If so, is it on all the time whether ignition is on or off? If yes, you have a bad ignition switch, since it is very unlikely you have a short going to both the coil and the ammeter/alternator. (Actually, all the meters should be off when ignition is off, not just ammeter.)

The only possible reason your engine is not turning off is because you are not cutting power to the coil. Electricity runs from your battery or battery switch to the large bolt on the starter solenoid, and from that bolt it powers the ignition switch. The ignition switch in turn energizes the coil allowing the engine to run (and connects to the ammeter/alternator), and also engages the starter solenoid when turned to the start position.

You are getting power to your ignition switch. You are getting power to your coil. And you are getting power to your solenoid since you can engage the starter and start your engine. The problem, then, is either your ignition switch not cutting power to the coil when you turn it off, or a short circuit (or incorrect wiring) somewhere else that is continually powering your coil. To test your switch, disconnect the wire from your coil to the ingition switch at the ignition switch. If you can successfully start your engine the problem is somewhere else. If you can only engage the starter but it won't turn over, replace the switch.
