Attwood Single Battery Switch - 12-50 VDC

The Attwood Single Battery Switch 12-50 VDC (Model 14233-7) is a heavy-duty marine battery disconnect switch designed for vessels requiring reliable single-battery power management across a wide voltage range. Built for saltwater and freshwater applications, this switch handles continuous loads up to 200 amps and intermittent surges to 300 amps, making it suitable for everything from fishing boats to recreational cruisers and offshore vessels with substantial electrical loads.

The 12-50 VDC operating range accommodates both traditional 12-volt systems and higher-voltage installations common in larger boats, while the on-off-separate control positions provide full isolation capability—essential for protecting battery banks during extended storage, maintenance, or emergency situations. The removable control knob deters unauthorized equipment operation while allowing quick access when needed. Ergonomic grips ensure reliable operation even with wet hands or heavy gloves, and removable side walls simplify internal access for cleaning and inspection in the corrosive marine environment.

This switch serves both weekend anglers managing small fishing boat electrical systems and serious offshore operators running navigation, sounder, and propulsion systems simultaneously. The compact form factor fits standard panel installations without extensive rewiring, while the high amp rating eliminates the need for upgrades as vessel systems expand. For any boater needing dependable battery isolation and load control, the Attwood single battery switch delivers marine-grade durability backed by years of OEM integration across the boating industry.
