Magnetic Tuning Switch swap?
#1

I'm working on a 38-116 and have it playing nicely.  The Magnetic Tuning switch has failed in the "On" position, however and I'm exploring options to replace it.  The switch won't move to the "off" position.  The part number is 42-1216 and it appears in the schematic as part #96.

   


I have a 37-11 parts chassis that includes a magnetic tuning switch which is identified as Philco Part number 42-1269 and it appears on the 37-11's schematic as #17

   

These switches appear to be functionally identical to my somewhat inexperienced eyes and I'm thinking that the difference in part numbers might be explained by the shaft lengths with the 38-116's being longer.  to deal with the thicker cabinet.  The difference in shaft lengths would be fairly easy to overcome with a coupler, at least that is what I'm thinking of doing.

Maybe I should leave the broken switch as it is since it is in the "on" position?  Your suggestions and insights would be appreciated.
