Attwood 4-way battery selector switch

The Attwood 14230-3 battery selector switch is a single-pole, four-position switch designed for flexible management of marine power systems. It allows selection between different battery sources or complete disconnection.

This selector switch offers four distinct connection modes:

Battery one: Uses only the first battery.Battery two: Uses only the second battery.Both batteries in parallel: Connects both batteries together.Both isolated: Completely disconnects both batteries from the system.

The primary function of this device is to prevent potentially damaging overvoltages that may occur during power source changes. This protects the alternator and other electrical components in the system.

The Attwood 14230-3 switch housing is made of bakelite. It is also fitted with brass terminals and nuts, along with copper washers, selected for their durability and resistance to corrosion in a marine environment.

It is considered robust for the marine environment due to its design and the materials used. Its bakelite housing, brass terminals and nuts, as well as copper washers, are selected for their durability and excellent resistance to corrosion typical of marine environments.

Positive click positions mean that each selection mode (battery one, battery two, both in parallel, or isolated) is clearly defined and locked by a click mechanism. This ensures precise handling and prevents intermediate positions or unintended selections.

The brand of this battery selector switch is Attwood.

The reference number (SKU) for this product is 14230-3.

The country of manufacture for the Attwood 14230-3 switch is Taiwan (TW).

No, this switch is a 4-way selector designed to manage at least two batteries. It allows you to choose between battery one, battery two, or both in parallel, which is not necessary for a single-battery system.

The switch measures 5-1/2 inches in diameter and 2-3/4 inches in depth. This corresponds approximately to 13.97 cm in diameter and 6.98 cm in depth.

This is a 4-way battery selector switch. Unlike a simple battery isolator that only connects or disconnects a single battery, this switch allows you to choose between multiple battery sources or connect them in parallel.

The Attwood 14230-3 switch is compatible with 6V to 32V DC electrical systems.

At 12V DC, the Attwood 14230-3 switch is designed to handle a maximum continuous current of 150 amperes.

At 6V DC, the Attwood 14230-3 switch is rated for a maximum continuous current of 300 amperes.

Yes, this switch is compatible with a wide range of DC voltages, including 24V and 32V systems, within its 6V to 32V DC compatibility range.

The Attwood 14230-3 switch is specifically designed and built with corrosion-resistant materials for the marine environment. While it can operate with 6V to 32V DC systems, its optimal use and durability are guaranteed for marine applications.

For installing the Attwood 14230-3 switch, it is recommended to use #10 screws.

Yes, this switch includes a disconnection device for the alternator excitation circuit. It is essential to follow the specific wiring instructions to ensure this safety function, which prevents overvoltages, operates correctly.

To ensure a secure and durable connection, it is important to clean the cable ends thoroughly and secure them firmly to the brass terminals of the switch using the provided copper nuts and washers. Proper tightening will ensure optimal conductivity and minimize corrosion risks.
