This switch builds on the standard dual circuit configuration by adding an emergency parallel function, allowing both circuits to combine in the event of a start battery failure. It’s a smart solution for ensuring secure isolation during normal operation and providing dependable backup power when needed.

Ignition protected and safe for use aboard gasoline-powered boats, this switch is ideal for marine and RV applications. The versatile case design supports surface, front panel, or rear panel mounting.

For performance and longevity, it features 3/8″-16 tin-plated copper studs for maximum conductivity and corrosion resistance, compatible with 3/8″ and M10 ring terminals. The 7/8″ stud length accommodates multiple cable terminals with ease.

Constructed from non-corrosive marine-grade metals and a reinforced polycarbonate housing, this switch is built to handle harsh environments. Tactile knob textures help identify switch position by feel, and the included international ON/OFF legends and ICON label set make circuit identification clear and intuitive.
