Separating the switch from volume pot
#1

I have a resistance of 30 to 70 ohms or so across the on/off switch contacts on the back of the volume potentiometer.  It varies as I wiggle the probes of the DMM.  I've tried contact cleaner and exercising the switch, but I need to get in there and polish the contacts.

Some of my repair parts literature mentions replacing the volume pot with "manufacturer part # xxx and adding the on/off switch contacts to the back of the pot".

Looking at my volume/on/off control, it looks like the switch on the back would come off, if I knew the trick of getting it to release.

Can anyone offer any guidance?  Is there another method of cleaning these contacts?  

Thanks in advance,
Dan
