The Advance Flight Systems AOA system needs to know if the RV10 is in cruising or landing configuration. A switch provides a ground input to their system and should be Normally Open (NO) until 30% of the flaps have been deployed...at which time the switch should close. When the switch closes, the AOA changes from the cruising configuration database to the landing configuration database. I installed the NO switch on a bracket and mounted the bracket on the cross spar with nut plates. Using a fly cutter, I cut a circle out of .063 stock that I shaped like a cam lobe. I riveted two clips to the cam lobe and secured it to the flap tube with a ring clamp. The cam lobe is then positioned under the switch flag. As the flaps deploy, the tube turns which turns the cam that is fastened to it with a ring clamp. As the flaps pass the 30% mark, the switch rides up on the cam lobe and forces the switch closed.
