Manual Battery Switches

Battery switches isolate the potentially destructive energy in the battery banks when the boat is not in use or during emergencies. They are available in different configurations according to the application.

These are familiar to most boaters as a large, usually red switch with a round face and prominent knob. The 4-position selector switch has long been the industry standard for managing the selection and charging of two battery banks. Blue Sea Systems has three families of manual battery switches.

  • The compact m-Series is rated at 300A continuous and is ideal for outboard motors or small inboard engines.
  • The standard e-Series has a 350A continuous current rating and is a popular replacement switch.
  • The heavy-duty HD-Series can carry up to 600A of continuous current, making it an excellent choice for boats with large diesel engines.

 

Blue Seas Battery Switch

Some switches have an auxiliary contact called an AFD (for Alternator Field Disconnect) which is used to disable the alternator field whenever the switch is turned to an open position. Otherwise, the alternator diodes are susceptible to damage by "cutting" the charge current to the battery.
