In stock online.

This innovative (patent pending) switch combines the functionality of three battery switches (House, Start and Emergency Parallel) into one by simultaneously controlling two battery banks and two loads. In the unlikely case of engine malfunction, a unique safety position isolates one load (e.g. House ON/Start OFF) so emergency radios call can be made. With improved access for cabling and three mounting options, the 772-DBC battery switch offers significant savings in space and installation time.
