 In this case the switch is mounted to detect the flap 2/3 extension
 position. The micro switch arm extends into the guidance rod channel and
 rides on
 the rod until the end passes and trips the switch. The sw is mounted on a
wee
 angle secured to the device in the same manner as the magnetic limit
 switches. Were I to do it again for the 300 series, I would sense 1/3
flaps (15
 degrees, 8 degrees out of reflex) and recalibrate) which would move the
switch to
 the left about 1.5 inches. Note that a bit of the rod channel was ground
 out so that the micro sw arm would not hang up by contacting the channel
sides.
