8d. For “normally closed” (NC) switching (code C switches), subtract 12 mm
from the measurement taken in step 7 and record the result. This distance will
be used to adjust the reed switch along the internal brass rod. The 12 mm is
subtracted to compensate for both the offset of the reed switch from the
actuation point (-6 mm), and the plug in the bottom of the stem (-6 mm). Refer
to drawings below.
