| Component | Description |
|---|---|
| Switch | Controls both the positive and negative connections to the battery simultaneously. |
| Battery | The 12-volt battery. |
| Positive (+) and Negative (-) Wiring | Separate wires for the positive and negative terminals, each controlled by the switch. |
Double-pole switches offer improved safety by completely disconnecting both terminals. However, they still only control a single battery.
Double-Pole Double-Throw (DPDT) Battery Switches
A DPDT switch is more complex, allowing switching between two different batteries or sources. This is common in setups with a house battery and a starting battery.
| Component | Description | Component | Description |
|---|---|---|---|
| Switch | Allows switching between two batteries (or a battery and a shore power source). | Battery 1 | (e.g., House Battery) Provides power to the trailer’s appliances. |
| Positive (+) and Negative (-) Wiring | Separate wires for each battery, controlled by the switch. | Battery 2 | (e.g., Starting Battery) Used to start the tow vehicle. |
| Output Wiring | Connects the selected battery to the trailer’s electrical system. |
The advantage is the ability to switch between power sources. The disadvantage is the increased complexity and cost compared to simpler switches. Improper wiring can lead to short circuits, so careful installation is essential.
