Blue Sea 1139 M-Series Battery Switch Mount Panel

The Blue Sea Systems 1139 M-Series Battery Switch Mount Panel is a finished black panel for installing compatible M-Series battery switches.

A battery switch mounted straight through a bulkhead leaves a raw hole and whatever gap the cutout ended up with. This gives a defined square panel around the switch, so the finish does not depend on how accurately somebody cut fiberglass with a hole saw.

That matters most on a refit, where an existing opening from a previous switch rarely matches the new one and needs covering neatly. It also helps present the switch in line with other electrical controls rather than sitting at whatever angle the old cutout dictated.

The panel is purpose-built for M-Series switches rather than a generic plate cut to fit. It suits a new electrical panel being assembled from individual components as much as a repair to an untidy existing installation. Explore more panel and switch accessories.
