RV Battery Disconnect Switch: Your Guide to Power Control
This guide helps you pick the right RV battery disconnect switch. It explains what to look for and how to choose the best one for your needs.
Key Features to Look For
A battery disconnect switch is important. It cuts off power to your RV’s electrical system. This is great for storage or when you aren’t using your RV. Here are key things to consider:
- **Amp Rating:** This tells you how much power the switch can handle. Get a switch that handles more amps than your RV uses. Check your RV’s electrical system and add a safety margin.
- **Voltage Rating:** Make sure the switch matches your RV’s battery voltage. Most RVs use 12-volt batteries.
- **Number of Poles:** A single-pole switch cuts off one wire. A double-pole switch cuts off two. Double-pole switches are often safer. They disconnect both the positive and negative battery cables.
- **Mounting Style:** Switches come in different styles. Some mount on the battery box. Others mount inside the RV. Choose a style that fits your RV.
- **Weather Resistance:** If the switch is outside, make sure it’s waterproof. This helps protect it from rain and moisture.
Important Materials
The materials matter for a good switch. They affect how long it lasts and how well it works.
- **Housing:** The housing protects the switch’s internal parts. Look for housings made of sturdy plastic or metal. They should resist corrosion.
- **Contacts:** The contacts are what connect and disconnect the power. They should be made of copper or a copper alloy. This helps with good electrical conductivity.
- **Terminals:** The terminals connect the wires to the switch. They should be strong and easy to connect to. Look for terminals made of durable metal.
Factors That Improve or Reduce Quality
Some things make a switch better. Others make it worse.
Improving Quality:
- High Amp Rating: A higher rating means the switch can handle more power.
- Weatherproofing: Protection from water and dust is good.

Reducing Quality:
- Low Amp Rating: The switch might fail if it’s overloaded.
- Poor Materials: Weak housing or contacts can break.
- Difficult Installation: A hard-to-install switch is frustrating.
- Lack of Weather Resistance: Moisture can damage the switch.
