BLUE SEA M-Series Battery Switch 6005 -?Mini On-Off Battery Switch with Key – Red?


300 Amps continuous rating for outboards and small gasoline or diesel engines.

The BLUE SEA M-Series Battery Switch 6005 is the mini battery switch that outperforms switches twice its size.

Blue Sea Systems’ m-Series Battery Switch, available in four practical models, is a great choice for most boaters. Its “mini” size, flexible mounting options, and current-carrying capacity make this battery switch a wise choice. The m-Series switch is versatile enough to meet just about any battery switch application for small and medium-size boats. It is very compact, measuring less than 3″ by 3″ (7.6cm X 7.6cm), making it ideal for installations where there are size and space constraints. In spite of its size, its current-carrying capacity exceeds many standard-size switches.
