1990 Mazda B2200 ignition switch problems

I already have a clutch that is good. This was installed brand new 5 years ago.

Oh no. That part is ok. It contacts well. All is well with the clutch pedal/switch. It is when I turn the toggle and attempt to crank the engine. When I did this on yesterday, I had to first get a jump for the batteries were dead. Once getting the boost was successful, the truck started like it should when one replaces the old starter with the new, however, when I had the engine running I wanted to try something which led me to believe that I also am going to need a new battery. I turned on everything associated with the electrical; such as all the lights, the radio, windshield wipers, etc, and when I did that the charge light appeared which led me to turn everything off before killing the engine. Finally, after killing the engine, the truck never turned over, although all the dash lights worked. Even after I attempted the jump start again, I still struggled with the crank. This has to be the ignition switch because it is draining my batteries. Would the 60 amp push button work just to start it until I can afford the new switch?
