Overview

The Blue Sea Systems 7901 is a red spare knob for the m-Series Mini battery switch, made to fit switch 6006. It replaces the knob only, which makes sense when the switch body and wiring are still in place and the issue is limited to the operating handle.

This part is useful at the main battery disconnect point when the original knob has been lost or damaged and you want to keep the switch easy to identify and turn by hand. It keeps the familiar red control on the m-Series Mini switch without changing the full switch assembly.

Key features

• Replacement knob for Blue Sea Systems m-Series Mini battery switch applications
• Fits Blue Sea Systems switch 6006
• Red knob matches the standard control color used on the 6006 switch
• Restores hand operation at the battery switch without replacing the full switch body

Compatibility and fit

Fit is the main checkpoint with this part. It is tied to the Blue Sea Systems m-Series Mini switch format, so it is worth checking the model on the switch before ordering. If your boat has a 6006 and the base of the switch is still serviceable, this replacement covers the knob portion only.

This is a practical match for boat owners, service yards, and installers who need to put an m-Series Mini battery switch back into normal use after the original knob is no longer usable.

Installation and use

Because this is a replacement operating piece rather than a complete switch, it is best used when the internal switch mechanism is still functioning as it should. On boats where the battery switch sits in a locker, battery compartment, or panel, replacing the knob can be a simpler repair than removing cables and changing the full switch.
