Sorry to hear of your health issues.   Here's a link to the Crosley 56TX schematic.

If I understand your questions correctly ... Usually the switch with 3 terminals on the side and two on the back are as follows.  The center of the 3 terminals is usually the wiper on the volume control resistor and the two end terminals correspond to the two ends of the resistor.  The two terminals on the back side of the switch are usually the on-off switch.  The on-off switch often fails, sometimes just from being dirty and sometimes from other problems.  

Here's a Philco 60MB volume control image:

I moved your thread to the non-Philco radios section.
