Blue Sea Systems makes the battery switches, ACRs, and rocker switches that control and protect your power. Size the switch to the load and wire it for safe battery management. Controlling power safely starts with the right switches. Blue Sea Systems builds the battery switches, automatic charging relays, source selectors, and rocker switches that run a clean electrical system. This collection covers battery disconnect and selector switches, ACRs, AC rotary switches, Contura rocker switches, and isolation covers. Choosing the right part comes down to the switching function you need and sizing the switch to the load.

A battery switch lets you disconnect the bank for safety and storage. In many setups it also lets you select which battery feeds the boat. Simple on off switches isolate a single bank. One two both selector switches let you choose battery one, battery two, both, or off. A dual circuit switch keeps the start and house banks separate while combining them when needed. Pick the switch that matches how your banks are wired.
An ACR joins the start and house batteries when a charging source is present so both banks charge. It then separates them so house loads cannot drain the starting battery. This is the simple hands off way to keep your engine battery topped and protected. Match the ACR amperage to your charging output.
AC rotary switches let you select between shore power, a generator, or an inverter. Only one source feeds the panel at a time. This is a safety must. Size the rotary switch to the AC amperage and the number of sources you run.
Blue Sea Contura rocker switches and labels build clean switch panels for pumps, lights, and accessories. Match the switch rating to the circuit load. Use the right base and labels for a finished panel.
Every switch has an amperage rating that must comfortably exceed the continuous load it carries. Undersizing a switch causes heat and failure. Add margin especially on high draw circuits like windlasses and inverters. Add AC isolation covers where required for safety.
Not sure which switch your system needs. Tell our techs your battery setup and the loads. We will match the battery switch, ACR, selector, and rocker switches so your power is controlled and protected.

An automatic charging relay joins the start and house batteries when a charging source is present so both charge. It then separates them so house loads cannot drain the starting battery. This is a simple hands off way to protect your engine battery.
An AC rotary switch lets only one source such as shore power, generator, or inverter feed the panel at a time. That prevents backfeeding and is a safety must on any boat with more than one AC source.
Every switch has an amperage rating that must comfortably exceed the continuous load it carries. Undersizing causes heat and failure. Add margin especially on high draw circuits like windlasses and inverters.
AC isolation covers shield live AC terminals to prevent accidental contact. They are required on many installs for safety. Match the cover to the module or switch it protects.
