The Perko Medium Duty Battery Selector Switch w/Key Lock is a marine-grade electrical control component designed for boats and vessels that operate dual or multi-battery systems. Built for reliability in harsh saltwater and freshwater environments, this selector switch allows operators to isolate, combine, or switch between battery banks with a simple turn of the key. Whether you're running twin engines, powering auxiliary systems, or maintaining onboard electronics, this switch provides the critical protection and control that serious boaters depend on.
The switch features Perko's proven bolt circle mounting pattern, making installation straightforward on new builds or as a drop-in replacement for existing systems. The integrated key lock mechanism prevents unauthorized battery switching and ensures that battery isolation doesn't happen unintentionally while underway—a critical safety feature when navigating or anchoring. Medium-duty rated construction handles typical recreational and light commercial marine applications without oversizing, keeping weight minimal at just 0.9 lbs while maintaining the corrosion-resistant build quality that Perko is known for. The compact 6 x 3 x 8-inch footprint fits cleanly into engine compartments and electrical panels on vessels of all sizes.
This selector switch is ideal for twin-engine boats, center consoles, and cruising vessels where battery management directly impacts engine reliability and onboard comfort. Anglers and cruisers who spend long hours on the water benefit from the ability to isolate dead or failing battery banks, ensuring that critical navigation, communication, and engine start systems remain operational. Installation aligns with standard marine electrical practices; consult your vessel's wiring schematic and Perko documentation to verify compatibility with your specific battery configuration and amperage requirements. The key-lock feature adds a layer of security and operational discipline that enhances overall vessel safety.
