6006 ON-OFF Battery Switch

The On-Off Battery Switch (6006) is a compact, ignition-protected master cutoff switch trusted by boat builders and professional riggers for dependable power isolation. Sized to fit tight compartments yet rated for serious current, it's a proven solution for cranking banks, accessory circuits, and clean, serviceable electrical layouts.

Why This Switch Matters

Reliable battery isolation prevents parasitic drain, simplifies maintenance, and provides an immediate safety shut-off when troubleshooting. A high-quality switch at this node reduces heat and resistance, improving long-term cable, terminal, and battery life.

Key Marine Specifications

• Type: Single circuit ON/OFF (2 positions)
• Max Voltage: Up to 48 V DC
• Continuous Rating: 300 A
• Intermittent (5 min): 500 A
• Cranking (30 sec): 900 A
• Terminal Studs: 3/8” (M10), tin-plated copper for corrosion resistance
• Ingress Protection: IP66 (splash and spray protected)
• Ignition Protected: Safe for gasoline engine compartments when properly installed

Built for Real-World Marine Use

The sealed case and reinforced internals withstand vibration, moisture, and temperature swings. Tin-plated copper studs improve conductivity and reduce corrosion in high-humidity environments.

Ideal Applications

• Primary master cutoff for cranking battery systems
• Accessory or trolling motor isolation on 12–24 V setups (rated to 48 V DC)
• Bass boats, multispecies rigs, center consoles, and performance aluminum boats

Installation Notes

• Mounts cleanly on flat surfaces (supports face or rear-panel mounting)
• Use marine-grade cable and properly crimped ring terminals
• Route wires to avoid chafe and maintain clear switch access

Pair This Switch With a Proper Mounting Bracket

For the cleanest install and easiest access, pair this switch with a purpose-built battery switch mounting bracket sized for your boat's battery compartment layout:
