To add to Bob's response, you can also test the NO/NC contact using a
multi meter on the ohm or continuity setting before you go about
soldering.  
 
Just to be sure you understand:
A non-pressed NO will show up as an open between the two contacts
A pressed NO will show up as a short between the two contacts
 
A non-pressed NC will show up as an short between the two contacts
A pressed NC will show up as a open between the two contacts
 
Open ~ Infinity Ohms (typically many Meg-Ohms)
Short ~ 0 Ohms (typically 1-2 Ohms)
 
Hope this helps!
Rodney

This is only possible in one of 2 ways:

1) Electrically if the microswitch in the pedal has 3 contacts, Common,
NO & NC. Then if it is using NO, use NC, else if using NC, use NO.

or

2) Mechanically, one user has said that in his switch, he was able to
physically reverse the orientation of the switch so that, for example,
if normally the contact is unpressed and pushing the pedal presses the
contact, he was able to change it so when the pedal was not depressed,
the switch lever was pressed, and when the pedal was pressed, the
microswitch lever was unpressed....

Otherwise, you need a new pedal......
