Electrics afloat need fittings built for the job. This collection covers marine-grade plugs, sockets and switches for boat electrical systems: waterproof deck plugs and sockets, 12V accessory and USB sockets, rocker and toggle switches, battery isolator switches and switch panels - all designed to resist the salt, damp and vibration that quickly destroy household components.
When specifying, match the fitting to the load (check the amp rating), the location (look for a suitable IP waterproof rating anywhere exposed to spray or weather) and the system voltage. Battery switches should carry your engine's full cranking current, and any deck connection deserves a properly sealed marine socket. If you're extending or troubleshooting a circuit, our marine cable and circuit protection ranges cover the rest of the job.
Frequently asked questions
What IP rating do marine switches and sockets need?
For cockpit and deck locations exposed to spray, look for at least IP65-rated fittings; below decks in dry areas, standard marine-grade components are sufficient. Higher is better anywhere water can reach.
Can I use household switches on a boat?
No - household fittings corrode quickly and are not rated for 12V DC loads, which arc more than AC. Always use marine-grade switches rated for your circuit's voltage and current.
What does a battery isolator switch do?
A battery switch disconnects your batteries from the boat's systems, preventing drain when you leave the boat and providing a safety cut-off. It must be rated to carry the engine's full starting current.
