Remote Switch Control for Your Boat — From Anywhere
The Garmin OnDeck™ 12V Relay Switch (Part No. 010-13009-01) adds remote on/off switching capability to your OnDeck™ system, letting you control onboard devices — lights, pumps, aerators, and more — directly from your smartphone via the ActiveCaptain® app. It's the practical upgrade for boaters who want hands-free control without being at the dock.
The OnDeck™ system supports up to 5 switches total, giving you a clean, centralized way to manage your boat's electrical accessories alongside real-time monitoring of battery status, bilge activity, shore power, and temperature — all in one app.

Parts Desk Insights
Best use case: This relay switch is the right pick for boaters who already have the OnDeck™ hub and want to add active control — not just monitoring — to their setup. It's especially useful for managing live well pumps, bait aerators, or cabin lights remotely when you're heading to the boat and want things ready before you arrive. If you need 24V compatibility instead, see the OnDeck™ 24V Relay Switch. For a hard-wired shore power option, check the OnDeck™ Shore Power Sensor (Hard-Wired).
