Battery switches and battery isolators

To avoid excessive battery discharges due to users inadvertently left on and for greater safety of the on-board electrical system, the boat battery switches, generally installed on the positive cable, allow you to isolate the battery without powering the electrical circuits. Nautical battery switches differ from each other in the maximum current capacity they are able to manage and in the mounting system, with or without built-in. Most are equipped with a removable key and a watertight cap to prevent water infiltration. The diverter battery switches can be connected to 2 batteries allowing you to alternately use only one, to use them both or to isolate them thanks to the 4-position switch.
