I bought a rotary disconnect as part of the van's electrical equipment. Its large physical control is a different kind of component from the small cable fittings and splices shown in my roof-wiring photographs.

Comparing the Physical on/Off Control
The roof wiring brought local leads toward the van entry.
I bought larger switching components separately from those cable-entry supplies.
This purchase added a rotary on/off control with rear threaded terminals.

My Takeaway from This Job
All three options use a rotary on/off action, while their bodies and mounting layouts differ. The two Blue Sea alternatives separate the compact m-Series format from the larger e-Series housing.
The rotary action can remain the same while the housing changes.

The visible handle is only one part of the space occupied by a rotary disconnect. Behind the panel, the terminal studs, lug bodies and cable bends need their own outline. Draw both sides before choosing the mounting position. A useful van equipment-board record identifies the exact switch and the cables at each terminal, while leaving room to operate the handle. That record remains useful if the surrounding cabinet or electrical-board layout changes later.
The Blue Sea 9003E is an e-Series rotary battery switch with on and off positions. Its red control turns within a mounting body with rear connection studs.
