Types of Battery Switches Used in Travel Trailers
Several types of battery switches manage power in travel trailers. The most common are simple on/off switches, dual battery switches, and battery isolators. Simple on/off switches are the most basic, offering only the ability to connect or disconnect the battery from the trailer’s electrical system. Dual battery switches allow you to select between two batteries (typically a house battery and a starting battery for the tow vehicle) or to connect both to the trailer’s system.
Battery isolators, often used in conjunction with solar panels or alternators, automatically manage the charging and discharging of multiple batteries, preventing overcharging or draining.
Typical Wiring Diagram for a Battery Switch System
A typical dual battery switch system involves a main power source (the batteries), a battery switch, and the trailer’s electrical system. The positive (+) cable from each battery connects to the switch’s input terminals. The switch’s output terminal then connects to the positive (+) bus bar of the trailer’s electrical system. The negative (-) cables from each battery connect directly to the trailer’s chassis, creating a ground.
This setup allows the user to select which battery powers the trailer or both. A more complex system might incorporate an isolator, which would sit between the batteries and the switch, managing charging currents automatically. Imagine a diagram where two batteries are represented by circles, labeled “Battery 1” and “Battery 2”. Lines represent wires, connecting the batteries to a rectangular box labeled “Battery Switch”, which in turn connects to another rectangular box representing the “Trailer Electrical System”.
A final line shows the negative terminals connected directly to the ground.
Operating a Battery Switch
Operating a battery switch is generally straightforward. For a simple on/off switch, simply flip the switch to the “on” position to connect the battery to the trailer’s system, and to the “off” position to disconnect it. Dual battery switches typically have multiple positions. One position will connect only the starting battery, another will connect only the house battery, a third position will connect both, and a fourth will disconnect both.
Always refer to your specific switch’s instructions for exact operation, as symbols and positions can vary. Before working with any electrical components, always disconnect the negative (-) battery cable to prevent accidental shorts.
