Sierra International RK19700 Illuminated Weather Resistant Contura III Rocker Switches Review

My Real Take on the Sierra International RK19700 Illuminated Weather Resistant Contura III Rocker Switches

As an outdoor and tactical gear specialist for over a decade, I’ve seen countless switches – some brilliant, some absolute garbage. The Sierra International RK19700 Illuminated Weather Resistant Contura III Rocker Switches piqued my interest because I’ve been increasingly focused on reliable electrical components for overlanding rigs and custom boat builds. These switches promised both illumination and robust weather resistance, crucial for demanding environments.

My old off-road rig’s auxiliary lighting system was controlled by a mismatched array of cheap, unlit switches that always left me fumbling in the dark. I needed a solution that was not only durable and weather-resistant, but also offered clear visual indication of switch position, especially at night. The Sierra International RK19700 switches seemed to fit the bill perfectly.

Upon unboxing, the build quality immediately impressed me. The plastic felt solid and well-molded, not cheap or flimsy like some other switches I’ve handled. The Contura III styling is a classic, and I appreciate the simple, clean aesthetic.

Compared to generic auto parts store switches, or even some supposedly “marine-grade” options I’ve used, these felt a class above. They seemed much more robust than the Blue Sea Systems switches I’ve installed in smaller electronics projects. I chose the Sierra International switches over other options specifically for their illuminated “ON” position and the stated IP66 and IP68 weather resistance ratings.

My first impression was positive and cautiously optimistic. I was excited to see if they could live up to the claims of weather resistance and durability under real-world use.

Real-World Testing: Putting Sierra International RK19700 Illuminated Weather Resistant Contura III Rocker Switches to the Test

First Use Experience

I installed four Sierra International RK19700 switches in my overlanding rig to control auxiliary lighting (driving lights, rock lights, and a rear work light). The initial installation was straightforward, fitting perfectly into standard Contura switch housings. Night one, I was immediately impressed by the clarity of the red illumination; it was bright enough to be easily visible, but not so bright that it was distracting.

I tested the switches during a weekend off-roading trip in the Mojave Desert. This included navigating through dust storms and one unexpected torrential downpour. The switches operated flawlessly throughout, with no signs of dust ingress or water damage.

The switches required no adjustment period; their operation was intuitive and reliable from the moment I installed them. There were no issues or surprises after the first use, only a growing confidence in their reliability.

Extended Use & Reliability

After six months of regular use, including several more off-road trips and exposure to varying weather conditions, the Sierra International RK19700 switches have held up remarkably well. There are no signs of fading, cracking, or degradation of the plastic. The illumination is still as bright and clear as it was on day one.

These switches have proven to be exceptionally durable; they’ve withstood extreme temperatures, constant vibration, and repeated exposure to dust, mud, and water. Cleaning them is simple – a quick wipe with a damp cloth is all it takes to remove any accumulated dirt or grime.

Compared to previous experiences with cheaper switches that failed within a few months, the Sierra International RK19700 switches have far exceeded my expectations. They deliver consistent performance and reliability that I can depend on in demanding situations.

Breaking Down the Features of Sierra International RK19700 Illuminated Weather Resistant Contura III Rocker Switches

Specifications

• Non-corrosive Plastic Construction: This resists degradation from UV exposure and chemicals. This is vital for longevity in harsh environments.

• IP66 and IP68 Standards: Protects against dust and prolonged spray (IP66) and continuous immersion in water (IP68). This provides exceptional protection in wet and muddy conditions.

• Meets UL 1500, ISO 8846 Ignition Protection Requirements: Ensures safe operation in marine environments and protects against ignition hazards. Safety is paramount when working with electrical systems in vehicles or boats.

• Supplied with Neoprene Mounting Gasket: Creates a watertight seal when installed in a compatible panel. This prevents water intrusion behind the panel, protecting other components.

• Illuminates Red in “ON” position: Provides clear visual indication of switch status, especially in low-light conditions. This is an essential safety feature, preventing accidental battery drain or equipment malfunction.

These specifications are critical because they directly impact the switch’s ability to withstand harsh conditions and provide reliable performance over time. The robust construction, weather resistance, and safety certifications inspire confidence in the product’s quality and durability.
