[R-390] R-392 microswitch

Gentlemen;
I'm trying bring this recently acquired R-392 back to life. It would work
long enough to tell it's in decent shape (although the dial seems to read 10
kHz high - I may have questions about that later). But it keeps dying - dial
lights and all, which I traced to the microswitch activated by a cam on the
main function switch. I've got the beast extracted, and it acts like it
might be fixable if I can get into it and clean the contact. I've pried the
seam with an X-acto pretty firmly but no luck yet.
Was just wondering if there's a secret method, or do I just need to pry
harder. Don't want to get in a hurry and trash it with no spare in sight. It
seems somewhat free all the way around the seam.
Is this the same switch that sticks ON on the R-390A? (Don't have one of
those yet.)
I'll take it to work tomorrow and look at it better under a microscope.
Yikes..  it's already tomorrow...

73,
Bruce
