Blue Sea Systems Remote Control Panel, for ML-Series Switches and ML-ACR, 12/24V DC, 3-Position

Overview

The Blue Sea Systems 1147 is a remote control panel for managing two ML-Series switches and one ML-Series Automatic Charging Relay from one 3-position panel. It works with 12V DC and 24V DC systems, and the panel measures 4.75 in high by 4.88 in wide with a 2.00 in depth, which helps when you are checking space behind a helm, nav station, or utility panel.

It comes with two 2145 SPDT Remote Control Contura switches with (ON)-OFF-(ON) action and one 2146 SPDT Remote Control Contura switch with ON-OFF-ON action. Lockout slides on the panel help reduce accidental switching when the boat is underway, tied up, or being serviced.

This panel suits boats that already use Blue Sea ML-Series remote battery switching and want the controls in a more accessible location than the battery compartment. Keeping switching and ACR control together at the helm or another frequently used station makes day-to-day operation easier and keeps the layout easier to read.

Key features

• Controls two ML-Series switches and one ML-Series Automatic Charging Relay from one panel
• 3-position layout for battery switching and charging relay control
• Works with 12V DC and 24V DC nominal systems
• Lockout slides help reduce accidental switch movement
• Panel size is 4.75 in x 4.88 in with 2.00 in depth for installations where rear clearance matters
• Includes illustrated labels, with a larger range of label options available for more customized panel layouts

Compatibility and fit

The 1147 is not a general-purpose switching panel. It is set up for Blue Sea ML-Series remote switching hardware, so fit starts with the electrical layout already on board. Check that your system uses two ML-Series switches and one ML-Series ACR, and confirm there is enough room for the panel depth and wiring behind the mounting surface.

It is a good match for cruising boats, fishing boats, and other setups where the high-current switching hardware stays close to the batteries while normal control is moved to the helm or another protected station. That arrangement keeps the operator from having to go back to the battery area each time a switch or relay function needs attention.

Installation and setup

The included switch set matters during installation. The two 2145 switches use momentary (ON)-OFF-(ON) action, while the 2146 switch uses maintained ON-OFF-ON action. Match those functions to the ML devices in your wiring plan before final assembly so the panel logic stays clear and consistent.

Clear labeling matters on a panel like this because battery isolation and charging functions need to be understood at a glance by anyone operating or servicing the boat. The included illustrated labels help with a standard layout, and the panel can support more specific labeling where the system calls for it.

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.
