Garmin Boat Switch

Meet the Garmin Boat Switch, a digital switching module that redefines how you manage onboard power. Designed for boaters with compatible GPSMAP or ECHOMAP chartplotters, it lets you run lights, pumps, horn and more from your display—reducing cockpit clutter and simplifying power management.

• Operate up to 20 circuits from your chartplotter: Direct control of lights, pumps, horn and other systems from a compatible GPSMAP or ECHOMAP chartplotter, replacing a bank of physical switches and fuses.
• Four switch types for flexible control: Toggle outputs for bilge pumps and non-dimmable lights; press-and-hold dimmers for cabin lighting; momentary outputs for horns and short-duration alerts; timers to circulate livewell pumps or other systems.
• Built-in tank sensing and system monitoring: Tank sender detection and calibration for up to four tanks, including fuel, freshwater, graywater, blackwater, and livewell; see levels at a glance to keep critical systems topped up and ready to go.
• Live system visibility: Analog voltages for house and start batteries and bilge pump operation—so you always know the health of your electrical system.
• Easy retrofit and setup: Retrofit into your existing boat without special tools or complex configuration. The kit includes 18" flying leads and color-coded channel wires for straightforward installation, plus the ability to name and position switches directly on your chartplotter display, replacing traditional fuse boxes with a single digital solution.
• Reliable marine-grade design: IP65 enclosure for protection in harsh conditions; operates on 12V DC (9-16V) with a maximum current of 50A and a power-off current of 60mA.
• Connectivity and channels: CAN-bus and NMEA 2000 networks for seamless integration with your marine electronics; NMEA 2000 Micro 5-pin M12 connector; channels supported via Molex MX150 L (16 circuits).
• Compact, capable hardware: 9.1" x 4.2" x 1.5" (unit only); weight 14.1 oz (400 g); output configuration includes 13 channels at 10A and 7 channels at 5A.
• What’s in the box: Garmin Boat Switch, Garmin Boat Switch Harness X1, Garmin Boat Switch Harness X2, Installation instructions.

With Garmin Boat Switch, replace cluttered fuse boxes with a single, integrated interface accessible from your chartplotter. See tank levels and battery voltages at a glance, and manage pumps and lights with precision. The retrofit-friendly design and marine-grade construction help you install quickly and operate confidently in challenging conditions.
