The switches are rated for 6,12, 24, or 32 volts:
Model 2110A switch features an alternator field disconnect which interrupts the alternator field when the switch is turned to the
preventing electrical surges in the armature circuit which might burn out the alternator diodes or ancillary equipment. Models 2111A and 2112A
do not include this feature and should never be turned to the
NOTE: These switches are designed as disconnect switches and are not to be used as load-breaking devices. If switch is used as load-breaking
device in emergency situation (e.g., starter malfunction), the switch should be replaced to avoid possible future failure.
MOUNTING: Switch should be located as close to (within 40
possible. Mount on a flat surface in an area that will remain dry and is protected from abuse. OPTIONAL: It may be necessary to remove the
adapter ring on some boats where the battery switch is fed through a thick panelboard.
WIRING: The battery cable should be sized in accordance with the engine manufacturer's recommendations. Other guides to wire sizes and
terminals may be obtained from the American Boat and Yacht Council electrical standards. The brass terminal studs for model 2110A, 2111A,
"
and 2112A are 3/8 diameter. Be sure all connections are securely tightened. Align the terminals such that they do not cause undue twisting at
the switch studs. See wiring diagram below for correct terminal installation. After connecting and mounting of switch, fasten the cables in
position with a suitable cable clamp no more than 6
Note: If the switch is mounted in such a way that the terminals are exposed, then the terminals should be taped or covered in order to comply
with Federal Ignition Protection Codes.
OPERATION: Always reserve one battery for engine starting. Use the second battery for lights, appliances, and other ship's service.
