Blue Sea 7350 C-Series Toggle Single Pole - 5A

The Blue Sea 7350 C-Series Toggle Single Pole - 5A is a compact marine electrical switch designed to protect and control high-demand systems on boats and fishing vessels. Built by Blue Sea Systems, a leader in marine electrical safety, this toggle switch combines a manual on/off control with integrated overcurrent protection—eliminating the need for separate components in tight engine compartments and console spaces. Anglers and boaters rely on this switch to safely manage inverters, bow thrusters, windlasses, and other 5-amp circuits where reliability in saltwater and freshwater environments is non-negotiable.

This single-pole toggle operates at 5 amps, providing the right amperage for moderate-draw auxiliary systems without oversizing protection. The white polymeric housing resists corrosion, UV degradation, and the harsh spray that comes with years on the water. Blue Sea's C-Series architecture integrates a thermal magnetic circuit breaker within the toggle mechanism itself, so the switch trips automatically under overload—protecting wiring and equipment while remaining resettable without replacing cartridges. The compact 3 x 2 x 4 inch footprint and 0.3-pound weight make it ideal for retrofit installations where space and weight savings matter on center consoles and cabin cruisers alike.

Experienced boaters and anglers installing auxiliary lighting, GPS units, windlasses, or bow thrusters will appreciate the tool-free installation and straightforward wiring. The 5-amp rating suits systems that draw steady current in the 3–5 amp range; for higher-demand applications, Blue Sea offers larger C-Series models. Marine electricians favor this switch for its proven track record in salt spray environments and its ability to reset instantly after a trip, keeping you on the water instead of troubleshooting at the dock. Installation requires only secure mounting to a bulkhead or console, standard marine-grade wire, and basic electrical connections—making this an accessible upgrade for DIY rigging or professional service work.
