Perko Medium Duty Battery Selector Switch Review

Let’s Talk About Perko Medium Duty Battery Selector Switch

The Perko Medium Duty Battery Selector Switch is a crucial piece of equipment for anyone managing multiple batteries in their boat, RV, or other off-grid electrical systems. Perko, a name synonymous with marine hardware, offers a switch designed to simplify battery management and protect your electrical system. This switch allows you to select between batteries for starting, charging, or operating them in parallel, all while safeguarding your alternator.

My journey to the Perko Medium Duty Battery Selector Switch began with a recurring problem on my old fishing boat. I constantly worried about draining my starting battery while running electronics, leaving me stranded miles offshore. I needed a reliable solution to isolate batteries and ensure I always had a reserve for starting the engine.

Upon receiving the Perko Medium Duty Battery Selector Switch, I was immediately struck by its robust feel. The materials felt durable, and the switch action was firm and positive. It seemed like a significant upgrade over the flimsy, generic switch I was replacing.

I considered several other battery switches from Blue Sea Systems and Marinco, but ultimately chose the Perko due to its established reputation for reliability and its clear and simple operation. The Perko switch also promised to interrupt the field current of non-unitized alternators, offering an added layer of protection that the others didn’t explicitly mention. My first impression was one of cautious optimism – the build quality seemed excellent, but the real test would be in its performance under the harsh marine environment.

Real-World Testing: Putting Perko Medium Duty Battery Selector Switch to the Test

First Use Experience

I installed the Perko Medium Duty Battery Selector Switch on my 22-foot center console fishing boat. The installation was straightforward, replacing the old switch with minimal fuss and using the existing wiring with slight modification. I tested the switch during a full day of offshore fishing, running my GPS, fish finder, and VHF radio, all powered by the auxiliary battery.

The switch performed flawlessly throughout the day, allowing me to easily switch between batteries for starting and running electronics. Even after a long day of heavy use, the switch felt cool to the touch, a testament to its 250 Amp continuous rating. No issues arose, even after accidentally splashing saltwater on it when hosing down the boat after returning to the dock.

Extended Use & Reliability

After six months of regular use, the Perko Medium Duty Battery Selector Switch continues to perform reliably. There are no signs of corrosion or wear, despite constant exposure to saltwater spray and the harsh marine environment. I periodically inspect the terminals and connections, applying a corrosion inhibitor to ensure optimal performance.

Compared to my previous, cheaper switch, the Perko offers a noticeable improvement in reliability and peace of mind. Where the old switch felt flimsy and unreliable, the Perko inspires confidence. It has proven itself to be a dependable component of my boat’s electrical system.

Breaking Down the Features of Perko Medium Duty Battery Selector Switch

Specifications

• The Perko Medium Duty Battery Selector Switch is designed for use with 6, 12, 24, and 32 volt marine electrical systems. This versatility makes it suitable for a wide range of applications.
• It boasts a 250 Amp continuous capacity and a 360 Amp intermittent capacity. This provides ample power handling for most typical marine electrical loads.
• The switch is ignition protected, reducing the risk of sparks igniting flammable fumes in the engine compartment. Safety is always paramount on a boat, and this adds an extra layer of security.
• Perko emphasizes the use of quality materials in its construction. This translates to increased durability and longevity, especially in harsh marine environments.
• The switch has a diameter of 5-1/4″ and a depth of 2-5/8″. These dimensions make it relatively compact and easy to install in most existing switch panels.
• Notably, when used with Non-Unitized Alternators, it interrupts the field current if turned “OFF” with the engine running. This minimizes the chance of damage to your valuable electrical equipment.

These specifications matter because they directly impact the performance, safety, and longevity of the switch. The amperage rating determines its ability to handle electrical loads without overheating, while the ignition protection minimizes the risk of fire. The quality materials ensure it can withstand the corrosive effects of saltwater and the vibrations of a marine environment.

Performance & Functionality

The Perko Medium Duty Battery Selector Switch performs its job exceptionally well. It provides a clear and reliable way to manage multiple batteries. Its simple operation, combined with robust construction, makes it a dependable component in any electrical system.

Its strength lies in its simplicity and reliability. The switch operates smoothly and positively, providing a clear indication of which battery is selected. A minor weakness might be the lack of a built-in fuse, which some users might prefer for added protection, though it’s typically managed separately within the electrical system. Overall, the switch meets and exceeds my expectations.

Design & Ergonomics

The Perko Medium Duty Battery Selector Switch features a simple and functional design. The materials used are robust and corrosion-resistant, giving it a solid feel. It’s designed for durability, not necessarily aesthetic appeal.

The switch is user-friendly, with clearly labeled positions for easy operation. There is virtually no learning curve – anyone familiar with basic electrical systems can use it. The positive switch action inspires confidence in its performance.

Durability & Maintenance

Given its robust construction and quality materials, the Perko Medium Duty Battery Selector Switch is expected to last for many years. I fully anticipate getting a decade or more of reliable service out of it. Maintenance is minimal, primarily consisting of periodic inspections for corrosion and cleaning the terminals as needed.

Accessories and Customization Options

The Perko Medium Duty Battery Selector Switch is a standalone unit and doesn’t come with any specific accessories. However, you’ll need appropriate gauge wiring and connectors to integrate it into your electrical system. The switch is compatible with standard marine wiring practices, allowing for easy integration with other electrical components.
