Advantages of Battery Switch
Safety
Battery switches are designed for use in environments where you would need to switch between battery banks or combine battery banks. What sets these battery switches apart from other types is the fact that they are not only built for safety but that they are built to handle the toughest environments out there.
Control your electricity usage
Having a battery switch on your boat allows you to control your electricity usage, especially regarding battery storage. For example, if you plan on leaving for a long time, you should switch your battery switch to “off.”
Preserve the other battery bank
Additionally, using your battery switch to draw power from a specific battery bank helps preserve the other battery bank. For instance, if you only draw power from your house batteries, you’ll have peace of mind knowing you have plenty of energy left in your starting battery.

What sets these battery switches apart from other types is the fact that they are not only built for safety but that they are built to handle the toughest environments out there. This makes them ideal for use in the marine environment. They can be installed in a multitude of locations and are even known for their ease of installation.
How Does a Battery Switch Work?
A battery on/off switch works by physically connecting or disconnecting the battery from the circuit. When the switch is in the "on" position, it completes the circuit, allowing current to flow from the battery to the device. When the switch is in the "off" position, it breaks the circuit, preventing current from flowing and effectively turning the device off.
The switch physically moves a conductive element, usually made of metal, to either bridge the gap between the battery terminals and the circuit, or to separate the connection. This interrupts the flow of electrons from the battery when the switch is in the off position. The switch may be a slide, toggle, button, or other type of mechanical control that the user operates to turn the device on or off as needed.
The Two Main Varieties and Ratings of Battery Switches
Battery switches come in two main varieties: single and dual battery. Single battery switches have two positions: OFF and ON. Dual battery switches have four positions: OFF, 1, BOTH, and 2. This type of switch is popular, since most boats have two identical general-purpose batteries, and the switch allows you to select any combination including having both batteries connected at the same time. For somewhat complicated reasons, we think the ideal setup is to have three ON-OFF switches in most instances, because it allows an engine battery to be used specifically with the engine, and a house battery (or bank) to be used for all the house loads, without interconnecting them. However, in practice, the majority of boats will have a dual battery selector switch.
Amperage ratings are generally given for continuous and intermittent use. Continuous ratings mean that a load like an inverter, which may run for an hour at a time, can be powered through the switch at the stated amperage. Most battery switch ratings range from 100A to 450A continuous. The intermittent rating is based on loads that operate for five minutes.
Battery Switch Guide
The boat is equipped with a dual circuit plus battery switch. The purpose of this switch is to isolate an engine battery from the house bank. When the switch is turned to on, the engine battery is connected to the engine and the house bank is connected to the house loads. The engine battery and house bank are completely separated so that all loads are connected to their respective batteries only.
Using a battery switch prevents the possibility of draining the engine batteries with house loads. In effect, the engine battery is left with only one purpose, to start and run the engine. When the switch is in the on position, the engine battery is connected to the starter and the house loads to the house battery bank. The most common method for connecting the alternator is to have it wired directly to the starter post. The alternator can be wired in a few other scenarios, but for now let’s review the typical setup. Effectively, whatever battery runs the engine will also receive the charge from the alternator.
When the switch is turned to combine, the alternators will charge both the engine and the house batteries. While underway, turn the switch to combine. The moment the engine stops, make sure that the switch is turned to on. If left on combine while not running the engine your house loads will drain both the house and the engine battery. Consequently if the batteries are drained too much, it’s possible that neither engine nor house will be able to start the engine. As a boat operator, you should be curious as to how your alternator is wired aboard your boat.
In the past, the second most popular setup was to have an alternator wired directly to a diode combiner and have the output of the combiner go to multiple battery banks, for instance, the house and engine battery. The advantage of this setup eliminated the two drawbacks above, but unfortunately seriously reduced the alternator output, because the diode combiner introduced a 0.6 to 0.7 vdc voltage drop.
Over the last decade, automatic charging relays (acrs) or voltage sense relays (vsrs) gained popularity. These devices allowed two batteries to be connected in parallel, automatically, if there was a charging voltage and disconnect once a pre-determined voltage was meet. This allowed for the alternator to be directly connected to the house bank, which needs the alternator charge the most. Once the charging voltage was reached, the house and engine batteries would be automatically combined so that engine battery would also receive a charge. Once the charge was gone, either battery became separate again. In our opinion, and for most cases, this is the best way to wire an alternator.
It is a different story while connected to shorepower or running your generator. The shorepower or generator powers the ac onboard and the ac, in turn, powers the converter (battery charger). In a typical setup, most battery chargers have three leads, one charger lead to the house battery bank, one to an engine battery, and one to another engine battery. While connected to shorepower or running the generator, there is no need to turn the switch to combine or both. You can confirm this by watching the voltage rise for all three battery banks while the charger is on and energized by an ac power source, without the switch turned to combine or both.
Factors to Consider When Choosing a Battery Switch
Voltage and current rating
Ensure the switch can handle your electrical system's voltage and current requirements. This information is usually labeled on the switch.
01
Durability
Look for switches made from corrosion-resistant materials, especially if your boat operates in saltwater environments.
02
Type of battery
Different types of batteries (lead-acid, agm, lithium) have varying charging requirements. Ensure the switch is compatible with your battery type.
03
Installation
Consider the ease of installation. Some switches might require professional installation, while others are designed for user-friendly setup.
04
Automatic vs. Manual
Decide whether you prefer the convenience of automatic systems like the automatic charging relay (acr) or if you're comfortable with manual switches.
05
The Importance of Battery Switches in Automotive Modification
A battery switch, is an electrical switch that interrupts the power supply from the battery to various electrical components of a vehicle. When activated, it cuts off the electrical connection, rendering the vehicle immobile and preventing unauthorized starting or operation.
