guest® Heavy Duty Selector Switch is “make-before-break”
single pole, triple-throw switch with alternator field circuit
disconnect for use where high amperage is required, such as
diesel engine starting. Rated at 360 amps continuous, 600
amps momentary, the switch is 5 1/2” square and 3 1/2” high.
warNiNG!
It is important that cold start amperage
requirements of your engine do not exceed the rated capacity
of this switch.
The switch features:
• Selection between either of two batteries or banks of
batteries, operation of both batteries or banks of batteries
in parallel, or complete disconnect of both batteries or
banks of batteries.
• Alternator field disconnect, which interrupts the alternator
field when switch is turned to “off” position, thus
preventing electric surges in the armature circuit which
might burn out the alternator diodes.
• Positive click stop in all positions, with large easy-to-read
dial.
• Rugged polycarbonate case with built-in skirt to protect
electrical connections. Can be panel or flush mounted.
• Heavy-duty copper contacts.
• For use with 6, 12, 24, and 32 volt systems.

Switch should be located as close to the batteries as possible
with regards to convenience of operation. The battery and
starter cable should be as short as possible.
There are three mounting positions:
1. Surface mounting with the wires going through the
openings at the base of the switch.
2. Surface mounted with a hole in the mounting surface to
permit wires to come through at the back of the switch.
3. Recessed mounting of the switch through a hole in the
mounting surface.
For surface mounting, place the switch in the desired location
and, using the switch as a template, locate the four mounting
holes. Then drill four equally-spaced #12 holes on 4 3/8”
centers.
For recessed mounting, place the switch in the desired location,
and using the switch as a template, locate the center. Cut
a hole 5 1/4” dia. to permit the silver face plate to extend
through the mounting surface. Then put the switch through
the hole from the back and locate and drill the four #12
mounting holes. These holes should be on 4 3/8” centers.
If flush mounting is desired, washers may be used on the
mounting bolts between the switch flange and the mounting
surface to adjust the portion of the switch that comes through
the hole.

1. Battery cable should be 4/0 or sized in accordance with the
engine manufacturer’s recommendations. Other guides to
wire sizes may be obtained from The American Boat and
Yacht Council’s Electrical Standards or The national Fire
Protection Association’s Standard for Motor Craft, nFPA
302. Terminals should be of the solder lug type. For 4/0
cable use Burndy #n250-250-MCM or equivalent. The
brass terminal bolts are 1/2” diameter.
2. Wire for alternator field circuit disconnect switch should be
#14 with terminal lugs on the ends. (See wiring diagrams
for suggested installations).
