Product Overview

A compact battery switch that switches a single battery to a single load group and offers multiple installation options

Blue Sea Systems m-Series battery switches are compact and waterproof and can be installed almost anywhere. The small footprint and three mounting options make installation easy. M-Series switches are ignition protected and can be located in the engine rooms of gasoline powered boats. A removable key adds a level of security and will prevent accidental power flow while servicing the electrical system. One piece tin-plated copper terminal studs are long enough to accept multiple cables and will handle the torque required to create a secure connection that minimizes resistance. For a small, versatile battery switch that is easy to install and use, look no further than the m-Series from Blue Sea Systems.
