Good To Know

Q: Can this switch be used on the positive battery cable? A: While it can technically be installed on either side, it is safest and most common to install a battery disconnect switch on the negative cable to prevent accidental short circuits.

Q: Is this switch waterproof for marine applications? A: The switch features a splash-resistant outer shell suitable for covered marine environments, but it should not be fully submerged or exposed to direct open-ocean salt spray.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
