Notes:
1. The N.C. circuit is the reference
circuit for the dual circuit switch;
the normally open circuit is not
adjusted. The expected dead band
between the N.C. & N.O. circuit
is shown in the chart below. For
applications requiring the normally
open circuit as the reference circuit
the N.C. circuit is not adjusted.

2. Switch may be adjusted so that:
A. N.C. circuit opens before N.O.
circuit closes.
B. N.C. and N.O. circuit have same
set point.
C. N.O. circuit closes before the
N.C. circuit opens. (There is no
dead band and both circuits are on
for a brief period of time.)

3. The tolerances given in the table
are applicable to a switch adjusted
so that the N.O. circuit closes
before the N.C. circuit opens and
applies to the N.C. circuit. The
N.O. set point and tolerances are
such that a minimum overlap of 1
PSI exists during which both circuits
are on.
