Blue Sea Systems SPDT Remote Control Contura Switch, ON-OFF-ON

The Blue Sea Systems SPDT Remote Control Contura Switch is the low-current pilot switch that operates Blue Sea's ML-Series remote battery switches and ML-ACR automatic charging relays from a convenient panel location — the switch itself doesn't carry the main circuit's load, just the control signal to the remote solenoid.

Key features

• SPDT (single pole, double throw), ON-OFF-ON action
• Red actuator, LED backlit for visibility at night
• Vibration, shock, thermoshock, moisture, and salt spray resistant
• IP67 rated — withstands temporary immersion
• Meets UL 1500 ignition protection and ISO 8846 marine standards

This switch is specifically designed to work with Blue Sea's ML-ACR Automatic Charging Relays (PN 7620, 7621, 7622, 7623, and their 100-series variants) and mounts in Blue Sea's Remote Control Panel (PN 1147) or any standard Contura-style cutout.

The ON-OFF-ON action gives three distinct control positions, useful for a remote battery switch that needs a momentary or maintained signal in either direction rather than a simple two-position toggle. Confirm which remote solenoid or relay model you're pairing this with, since Blue Sea's Contura switch family includes several action types (ON-OFF-ON, [ON]-OFF-[ON], ON-ON) built for different control requirements — using the wrong action type with a given remote device may not give the expected control behavior.

Because it's rated IP67 and built to withstand vibration and salt spray, this switch holds up well at an exposed helm or flybridge position, where a standard household-grade toggle switch would corrode or fail within just a single season or two of routine exposure.
