Blue Sea 1206 120V AC Main + 2 Positions w/AC Voltmeter

The Blue Sea 1206 120V AC Main + 2 Positions w/AC Voltmeter is a marine and automotive-grade AC power distribution panel designed for vehicles and vessels that operate dual 120V AC systems. This selector switch allows you to toggle between two independent AC power sources or an off position, making it essential for RVs, expedition vehicles, mobile workshops, and marine installations where redundant power or switchable generator/shore power configurations are required.

This 120V AC main switch features a rotary selector that allows isolated control of two separate AC circuits—ideal for switching between an onboard inverter and a generator, or primary and backup shore power supplies. The integrated AC voltmeter display provides real-time feedback on voltage output, helping you monitor system health and diagnose power anomalies before they damage sensitive electronics. Housed in a compact, professional-grade enclosure, this unit delivers reliability while maintaining a clean panel appearance.

Blue Sea's reputation for corrosion-resistant construction and fail-safe design means this selector will perform dependably in harsh environments—salt spray, vibration, temperature extremes, and constant power cycling. This unit is indispensable for anyone building a dual AC system in their vehicle or vessel, ensuring seamless power management and enhanced operational efficiency.
