Bluewater OFF/1/2 Battery Switch - Surface Mount - Red

OFF/1/2 Battery Switch - Surface Mount - Red

This 1/2/Off switch offers seamless selection between two power sources, with an Off position for isolation. It’s a reliable solution for switching between primary and secondary batteries in compact or mobile applications, such as boats, RVs, or service vehicles.

Ignition-protected and safe for use aboard gasoline-powered boats, the 1/2/Off switch is built for flexibility with a case design that supports surface, front panel, or rear panel mounting. 

To ensure lasting performance, the switch features 3/8″-16 tin-plated copper studs for strong conductivity and corrosion resistance, compatible with both 3/8″ and M10 ring terminals. A 7/8″ stud length accommodates multiple cable terminals when needed.

Constructed from marine-grade, non-corrosive metals and a reinforced polycarbonate housing, it’s made to endure harsh environments. Tactile knob textures allow you to identify the position by feel, and both international ON/OFF legends and an icon label set are included for easy circuit labeling.
