 __THEORY OF OPERATION__<br> 
  
 The function of the toggle switch contacts is as follows: 
 The “1” set of contacts selects the appropriate harmonic from the drawbar or terminal strip wire and routes it to the “H” (percussion input on AO-28) terminal. The “2” set of contacts are wired in series to isolate “HW” from terminal “H” anytime a harmonic is selected. The “3” set of contacts on S2 and S3 isolates the 2nd and 3rd harmonic from the console selector rocker tablet so there is no interaction between the 2nd and 3rd harmonic.
