Hella Marine Battery Master Switch Spare Key, For 150A Switch 2843, Key Removable in OFF Position

Overview

The Hella Marine 706729011 is a spare key for the Hella Marine 150A Battery Master Switch (2843 series), so you can still shut down or restore DC battery power if the original key goes missing.

It fits the keyed switch used to isolate your boat’s electrical system, and the key can be removed when the switch is in the OFF position so current is fully interrupted.

Keeping an extra key onboard is a simple way to avoid a no-start situation at the dock, and it also helps when you routinely remove the key to leave the battery switch OFF while the boat is unattended.

Key features

• Replacement key for Hella Marine Battery Master Switch series 2843 (150A keyed switch)
• Key-removable OFF position so the switch can stay fully disconnected without a key left in place
• Restores normal battery switch control if the primary key is lost or damaged
• No electrical work required since this is a mechanical key for the switch actuator
• Easy to store as a labeled spare in your onboard electrical spares kit

Compatibility and fit

This key is intended for the Hella Marine 150A Battery Master Switch in the 2843 series. Confirm your switch is the keyed version before ordering, since non-keyed battery switches use different knobs and hardware.

Installation and operation

There is no wiring or setup. Insert the key into the battery master switch and turn the switch ON or OFF as needed. When the switch is OFF, the key can be removed to leave the circuit disconnected.

As with any battery isolation switch, shut down high-draw DC loads and chargers before switching OFF to reduce arcing at the contacts and avoid nuisance resets onboard.

Use on board

This spare key is a good match for boats that use a keyed battery master switch as a regular shutdown point, especially when the switch is mounted in an engine room, cockpit locker, or battery compartment where keys can get misplaced.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
