Solder the conductors to the switch terminals to ob-
tain the desired function (see Figure 3 for switch
configuration.) Take care no to leave long bare con-
ductors that may bridge across terminals and make
unintended connections.

NOTE: When the switch is used to make connections in
the middle of a cable run, It is very important to preserve
continuity in the cable shield. If a splice is necessary for
this, be sure it is insulated from other terminals, or you
may employ an unused switch terminal to make the con-
nection. Leaving the shield discontinuous may cause
undesirable hum in a circuit.

TERMINAL SIDE OF SWITCH

FIGURE 3

Assemble the switch by inserting the tab on the bot-
tom back of the switch into the slot in the upper case
front. (See Figure 4)

Insert the flange in the flex relief into the slot be-
tween the case bottom and the small horizontal pro-
jection.

If the strain relief is used, align its hole with the hole
in the center boss in the lower case front. Align the
cable to one side of the boss.

NOTE: If the cable is knotted to provide a strain relief,
the center boss in the case may be inserted through the
center of the knot with the cable lying to the side of the
boss.

ASSEMBLING THE SWITCH

FIGURE 4

Use the three provided thread-forming screws to
fasten the case back to the case front, making sure
not to pinch any leads. (If the strain relief is used,
make certain that it is captured by the screw through
the lower center back of the case.)
