Bob Smiley, Thanks for sending in the photos.  They are most helpful.  How long ago
did you purchase your EC100?  I ask because, when I had mine open, it
looked like there was a SPDT switch when your photo clearly shows a
DPDT configuration.  I am thinking that there may have been a revision
since you got your unit, that may have changed the switches.  I bought
mine in August 2002.
