Garmin OnDeck Relay Switch 24v

The Garmin OnDeck Relay Switch 24v is a marine-grade remote control module designed for vessel operators who demand reliable automation and hands-free control of onboard systems. This 24-volt relay switch integrates seamlessly with the Garmin OnDeck Hub ecosystem, allowing you to remotely manage multiple electrical circuits and auxiliary equipment from a single digital command center. Whether you're controlling navigation lights, thruster systems, bilge pumps, or auxiliary power distribution, this relay switch eliminates the need for manual panel switching and reduces cockpit clutter on modern vessels.

Engineered to withstand harsh marine environments, the Garmin OnDeck Relay Switch 24v operates on a 24-volt DC power input, making it compatible with most modern marine electrical systems. The switch leverages solid-state relay technology to provide silent, maintenance-free operation without the mechanical wear associated with traditional electromechanical relays. Weighing just 1 pound, its compact form factor fits easily into tight engine compartments or electrical enclosures. The OnDeck Hub architecture supports up to five relay switches, giving you scalable control over multiple independent circuits without requiring additional hubs or complex wiring modifications.

This relay switch is ideal for cruising sailors, fishing boat operators, and yacht owners who have already invested in the Garmin OnDeck Hub platform and seek to expand their vessel automation capabilities. Installation requires integration with the OnDeck Hub via the proprietary connection protocol; consult your hub documentation to verify input power compatibility between 10–32 volts DC. The switch's industrial marine-grade construction ensures long service life in salt spray, UV, and vibration-prone environments. For best results, pair this relay switch with a complete OnDeck system configured by a Garmin-certified marine electronics technician to ensure all circuits are properly protected and fused according to marine electrical standards.
