Double Pole Switches: What They Are and Why They Matter in Your Caravan
When you’re setting up or upgrading your caravan's electrical system, safety should always come first. One of the most important, but often overlooked, parts of that system is the double pole switch. Whether you’re plugging in at a caravan park or powering high-load appliances like a microwave or air con, understanding how double pole switches work can save you from major headaches down the road.
Let’s break it all down in simple terms.
What is a Double Pole Switch?
A double pole switch is an electrical switch that disconnects both the active (live) and neutral wires at the same time. This ensures the appliance or outlet is completely cut off from power, making it much safer to use and maintain.
In contrast, a single pole switch only cuts off the active wire, which means there’s still a chance the device could carry a charge—especially dangerous in confined caravan spaces.
Why Are Double Pole Switches So Important in Caravans?
Caravans and RVs use both 12V and 240V systems. The 12V system powers things like lighting and water pumps, while the 240V system (also called mains power) runs higher-draw appliances like kettles, toasters, or air conditioning units.
When using 240V power, especially with 15amp extension leads, the law requires that all switches and power points in your caravan must be double pole. Why? Because:
-
They fully isolate the appliance from the power source
-
They make maintenance safer
-
They reduce the risk of electrical shock or short circuits

Double Pole Switches vs Circuit Breakers
It’s easy to confuse double pole switches with circuit breakers, but they’re not the same.
-
A switch manually turns power on and off
-
A circuit breaker automatically cuts power when there’s a fault, like an overload or short
Both are important but for everyday control and safety, the double pole switch plays a crucial role.
Where You'll Find Double Pole Switches
You’ll typically find double pole switches:
-
At 240V power points in caravans
-
On high-load appliances (e.g. ovens, fridges)
-
In any switch or socket installed under current Australian regulations
If you’re retrofitting your caravan or installing new outlets, double pole is non-negotiable.
How Double Pole Switches Are Wired
Wiring a double pole switch is a bit more involved than wiring a single pole.
-
A single pole switch has 2 terminals (just breaks the active/live wire)
-
A double pole switch has 4 terminals (breaks both active and neutral wires)
Proper wiring ensures full disconnection when the switch is off. If you’re unsure, it’s best to get a licensed electrician to handle any 240V wiring.
Stay Safe with the Right Gear
When you’re powering your RV with a 15amp extension cord, you’re already dealing with higher current than a standard 10amp household plug. That’s why you can’t use regular single pole switches or power points, they’re simply not built for the job.
You can find compliant extension leads, double pole switches, and adapters like Ampfibian 10A to 15A connectors online at Caravan & Camping Aus.
FAQs About Double Pole Switches
What is a double pole switch used for?
A double pole switch is used to safely disconnect both active and neutral wires at the same time—great for high-power appliances and required for caravan 240V systems.
Do I need a double pole switch in my caravan?
Yes. Australian regulations require all 240V power points and switches in caravans to be double pole for safety.
Can I install a double pole switch myself?
Unless you’re working with 12V only, any 240V electrical work must be done by a licensed electrician.
What’s the difference between a double pole switch and a circuit breaker?
A double pole switch is manually operated to turn power on or off. A circuit breaker automatically cuts power if something goes wrong (like a surge or overload).
Where can I buy double pole switches and 15amp caravan gear?
You can shop a full range of caravan electrical gear, including double pole switches, power points, adaptors, and 15amp leads at Caravan & Camping Aus.
Final Thoughts
Whether you’re upgrading your caravan or just learning the ropes, understanding double pole switches is a must. They’re not just another piece of hardware—they’re a vital part of keeping your van safe, legal, and functional.
