I tested my new switch to see see if it agreed with the Duet Sport manual.  According to my tests:
Pin 1 is the one with the biggest open space beside it (opposite of what is stated in the manual)
Tests:
4 and 6: Without blowing, 0; blowing, none (this is opposite of what is stated in manual)
1 and 2: Without blowing, none; blowing, 0.
4 and 5: Same as 1 and 3
3 and 4: Same as 1 and 3 but have to blow harder to get 0
