Michael -

This is in our ES, but the principles would be the same for your 320. The first two pictures are of the flap microswitch. Email me if you have any questions.

  I'm in the middle of installing an AOA in to my five year old 320 - doing  it
  though the wing tip rib.  It would help me if someone could send me a  photo
  of the installation of the flap microswitch.  This would save me  having to
  think to hard about where to put it!
    Thanks in advance.

[Michael... I don't have a photo of the flap microswitch installation in a 360 but it is a pretty simple process.  You want to position it right next to (or over) the central flap belcrank in such a way that it gets actuated when the flaps are at 0 degrees (retracted) and throughout the reflex position.  I don't know which actuating lever you have on your switch, although I suspect it's just a straight spring steel lever, or maybe one with a 1/2 loop on the end.  If you locate it so the lever rides up onto the belcrank and causes the switch to click at the zero degree flap position and remain "clicked" throughout reflex you've got it right.  You want to use the normally closed contacts so the switch is un-actuated once the flaps are moved into any amount of down position.... the NC contacts will send the ground to the AOA indicating flaps down.  That's about it.   <Marv>      ]
