Now that the whisker is bent, take the wire out of the PCB hole. Add a
#4-40 x 3/8" Screw (V) from the bottom and loop the bent whisker around
the screw. Hold this tight and secure it with a the #4-40 nylon standoff.
Note: It is very important that you do not let the whisker touch the hex nut or
screw on the other side. This is what triggers the sensor. Leave a little
space between the wire and other side’s nut.
Twist and tighten the #4-40 nylon standoff on top of the screw to secure the
whisker.
