Perko Compact Medium Duty Battery Selector Switch w/o Key Lock

The Perko Compact Medium Duty Battery Selector Switch without Key Lock is the marine electrician's trusted choice for managing multiple battery banks on vessels ranging from center consoles to cruising sailboats. Built for 12, 24, and 32-volt systems, this compact selector serves as both a battery switch and main disconnect—critical safety features for any boat with dual or triple battery configurations. Anglers and cruisers depend on this switch to isolate batteries during storage, prevent parasitic drain, and safely manage charging circuits across their onboard electrical network.

This Perko unit delivers higher amp ratings than the popular 8500 series while maintaining the same bolt-pattern compatibility, making retrofit installation straightforward on existing panels. The smooth, positive-position selector mechanism provides tactile feedback—you'll know exactly where the switch sits every time. Ignition protection prevents accidental arcing, and the compact footprint (5 x 3 x 8 inches) fits tight marine panel spaces without consuming valuable dashboard real estate. At just under a pound, it adds negligible weight while handling the electrical demands of modern marine systems.

Boaters running twin-engine setups, separate house and start batteries, or integrated solar and generator circuits will find this switch indispensable for safe electrical management. It's equally at home in a professional fishing vessel's cabin as in a weekend recreational boat. Installation works on fiberglass or metal panels; verify bolt pattern compatibility with your current switch if upgrading. This is the selector switch serious water-time operators choose when reliability and operational simplicity matter most.
