NOTE:
When
you
install
the shields in
the following
steps,
be careful
not to pinch and wires
between
the
shields
and the circuit
board.
(
)
Refer to Detail
2-9C
and mount
a band switch
shield to rotary switch
SW403
as shown.
Use
a
4-40 x
3/8"
screw,
a #4 lockwasher,
and a
4-40
nut. Be sure
the shield is
on the correct

all of the pins
are in their
circuit board
holes. Then
solder one of the

sure the switch
is tight
against and
perpendicular to
the circuit board;
then
solder the
remaining pins to the
foil.
