Moeller Marine Battery Disconnect Switches & Terminal Covers

A marine battery installation benefits from the right disconnect switch and protected electrical terminals. Compare Moeller's keyed and rotary switching options, then choose individual red or black battery-post covers or a packaged pair. The exact part number determines the function and configuration.

Two battery-disconnect designs

042219-10 — removable-key switch

A key-operated disconnect with a protective cap around the removable key. Mounting and electrical specifications must match the existing system.

042228-10 — rotary on/off switch

Rotary one-battery on/off model with a specified 200 A continuous rating. Do not confuse it with Moeller's separate battery-selection switch models.

Fit and installation considerations

The keyed 042219-10 and rotary 042228-10 are separate designs. The rotary model is catalogued for one-battery on/off control at 12–50 V DC with a 200-amp continuous rating; confirm the full electrical requirements and any surge rating before selection. For the keyed model, confirm the marked switch ratings and wiring terminals for your installation. Only use covers that fit the cable and terminal geometry.

The battery-box strap is a separate part

Moeller 042217-10 is a replacement strap and fastening-hardware item, not a battery switch or terminal boot. Confirm the box, restraint arrangement and required strap length before ordering.

See replacement strap listing

Battery circuits should be isolated before working on terminal covers or switch connections. Follow the electrical-system manufacturer’s instructions and applicable marine electrical standards for wiring and protection.
