Compatibility & Fitment

• Application: Designed for marine vessels, RVs, and heavy-duty vehicles with multi-battery systems.
• System Voltage: Compatible with 12V, 24V, and 32V DC electrical systems.
• Terminals: Accepts 3/8"-16 (M10) ring terminals.

When to Replace

• Switch fails to make a reliable connection, causing intermittent power.
• Physical damage to the housing, terminals, or selector knob.
• Signs of overheating, arcing, or melting at the terminals.
• Selector knob becomes excessively stiff, loose, or will not engage in a set position.

Installation Tips

• Disconnect all battery negative terminals before starting the installation.
• Use marine-grade wiring and terminal lugs sized appropriately for the system's amperage.
• Ensure all cable connections are clean and tighten terminal nuts to the manufacturer's specified torque.
• Mount the switch in an accessible location, protected from direct spray and physical impact.
• After installation, test all switch positions to confirm correct operation before reconnecting loads.
