Remote Switch Control for 24V Vessels — From Anywhere
The Garmin OnDeck™ 24V Relay Switch (Part No. 010-13009-07) brings remote on/off switching to 24-volt electrical systems, letting you control onboard devices — lights, pumps, aerators, and more — directly from your smartphone via the ActiveCaptain® app. It's the purpose-built choice for twin-engine boats, larger cruisers, and any vessel running a 24V electrical system.
As part of the Garmin OnDeck™ remote monitoring ecosystem, the system supports up to 5 switches total and pairs with battery, bilge, shore power, temperature, and security monitoring — all managed from a single app.

Parts Desk Insights
Best use case: This is the correct relay switch for any vessel running a 24V electrical system — most commonly twin-engine outboard rigs, larger inboard cruisers, and some commercial or semi-commercial vessels. If you’re unsure whether your boat runs 12V or 24V, check your battery bank configuration: two 12V batteries wired in series = 24V system. For 12V systems, see the OnDeck™ 12V Relay Switch instead. For a permanent shore power monitoring solution, the OnDeck™ Shore Power Sensor (Hard-Wired) pairs well with this switch in a full build-out.
