Blue Sea 7717 – ML-RBS Remote Battery Switch Auto-Release 24V DC 500A SPST with Manual Control
The Blue Sea 7717 ML-RBS Remote Battery Switch is a 24V DC magnetic latching battery switch with auto-releasing coil and SPST switching, designed for high-amperage circuits with both remote and manual control capability. It supports switching under load and applications where a normally open relay behavior is required.
A built-in manual override knob allows operation with or without power and provides a LOCKED OFF position for servicing. The switch uses silver alloy contacts for reliable live-load switching and tin-plated copper studs for conductivity and corrosion resistance. An LED output is available for remote switch state indication (optional LED required).
