Perko Heavy Duty Battery Selector Switch w/Alternator Field Disconnect

The Perko Heavy Duty Battery Selector Switch with Alternator Field Disconnect is designed for serious boaters and anglers who require reliable multi-battery power management in challenging marine environments. This switch addresses the critical need to isolate batteries during storage, prevent parasitic drain, and easily switch between multiple battery banks while safeguarding alternator output.

Constructed with heavy-duty materials, the Perko selector switch features a mechanical field disconnect that protects your alternator during switching operations, preventing voltage spikes and extending alternator life. The switch offers four distinct positions: battery one, battery two, both batteries (parallel), and OFF, providing flexibility in power distribution across starting, trolling motor, and house loads.

Boat owners managing dual battery systems, fishing boats, and cruising vessels will find this selector switch particularly beneficial. Its corrosion-resistant terminals and robust electrical contacts ensure years of reliable operation in salt spray, humid engine compartments, and high-vibration conditions typical of marine service.
