87 electrical issues, general

[coman]

Hello Comanche Chieftains.  87 Comanche:  I replaced the ignition power switch on the steering column.  This solved the immediate issues but....How do I fix it so there is not a melting switch failure again?  For several days after the replacement I have burning and melting smells.  I read about poor designs but can it be fixed?  I am running out of nickels and dimes..  I do wish to sell it to get a Grand Cherokee that will meet my needs.  Straight trade is OK.
