Product Overview

500 Amp magnetic latching switch provides high amperage switching under load, manually or from remote locations.

Blue Sea Systems designed the ML-Series heavy duty remote battery switch to make controlling large battery banks push-button convenient. Because of their size and cable requirements, conventional battery switches are typically located in a lockers, or behind a seats and out of reach.

Installation of a remote switch has two benefits: it puts the control of the switch right on the dash or nav-station and it shortens heavy cables runs by putting the switching mechanism close to the battery. Included is a Contura style switch that requires only light gauge wire and will easily fit next to (if not match) other dash mounted switches. A sliding cover on the remote switch prevents accidental switching.

 The ML-RBS switching mechanism can be mounted close to the batteries to limit heavy gauge cabling. For added safety a manual control lever with lock out feature has been built into the ML series switches; you will always be able to control the battery even if the wiring to the dash mounted switch is compromised. The service lock-out offers a level of safety when working on the electrical system.
