An easy way to check if your problem is battery related or ignition related is to put the trans in N, key in the on position, pull the starter relay and jump the switched side of the relay receptacle with a little pair of needle nose pilers. That will bypass your ignition switch entirely and send battery voltage directly to the starter. If she cranks then you know your problem is in the ignition circuit (probably a broken actuator pin), if she doesn't crank then you know you have a problem with the battery or starter. A picture of the starter relay terminals is in the above linked thread.
