Blue Sea Systems Contura II Rocker Switch, Black Actuator, 20A @ 12V, 15A @ 24V

Overview

The Blue Sea Systems Contura II Rocker Switch is a black DC panel switch range for boat electrical panels, with configurations covering SPST, SPDT, DPST, and DPDT switching needs. The range is rated up to 20A at 12V DC and 15A at 24V DC, making it suitable for common low-voltage marine circuits when the selected switch configuration matches the circuit layout.

These Contura II switches mount in Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels. They use an internal and external gasket panel seal and are made to handle vibration, shock, thermoshock, moisture, and salt spray, which matters in cockpits, helm stations, cabins, and other areas exposed to the movement and conditions found on boats.

The operating temperature range is -40 C to 85 C. LED-equipped versions use 18mA operating current for the indicator and have LEDs rated for 100,000 hours half-life, while non-LED versions are available for circuits where illumination is not needed.

Key features

• Black Contura II rocker style for a clean match with Blue Sea Systems Contura switch panels.
• Rated for 20A at 12V DC and 15A at 24V DC, covering many common boat DC control circuits.
• Available in SPST, SPDT, DPST, and DPDT pole and throw layouts for simple loads, selector functions, and paired circuit control.
• Maintained and momentary switch actions are available, including OFF-ON, OFF-(ON), ON-OFF-ON, (ON)-OFF-ON, ON-ON, and related configurations.
• LED options include none, single LED, and dual LED indicators depending on the selected variant.
• Internal and external gasket panel seal helps maintain panel sealing when used with compatible Contura water-resistant panels.
• Resistant to vibration, shock, thermoshock, moisture, and salt spray for use in marine panel locations.
• Operating temperature range of -40 C to 85 C supports use in exposed helm areas, cabins, and equipment spaces.

Variants

This product family is offered in multiple switch configurations. The key differences across the range are the switch action, the pole and throw layout, and whether the rocker includes no LED, a single LED, or dual LED indicators.

All listed versions use the black Contura II actuator style and are intended for compatible Blue Sea Systems Contura panels. The correct version depends on the circuit being controlled, such as a simple light circuit, a momentary horn or wiper circuit, a bilge pump control, navigation and anchor light switching, or a circuit that needs double-pole control.

Installation and setup

For a proper installation, match the pole and throw arrangement to the wiring diagram for the equipment being controlled before cutting, crimping, or terminating conductors. Parentheses in the switch action indicate a momentary ON position, which returns when released, while positions without parentheses are maintained positions.

These switches are meant to mount in compatible Contura panel openings rather than as loose inline switches. Using the correct Contura panel or mounting bracket keeps the rocker seated correctly and helps preserve the panel sealing expected in a marine installation.

Electrical and system integration

The 12V and 24V DC ratings make this range useful for many boat electrical systems, but the connected load must stay within the rated amperage of the selected switch. LED versions are useful where the operator needs visual feedback at the helm or switch panel, while non-LED versions keep the panel simpler and avoid indicator current draw.

SPST versions suit basic on-off or momentary single-circuit control. SPDT versions support switching between two outputs or control states. DPST and DPDT versions are used where two circuits or two poles must be switched together through the same rocker.

Use cases on board

This range fits boat owners and installers building or refreshing a DC switch panel with a consistent Contura II look. Depending on the selected configuration, the switch can be used for lights, horn or wiper circuits, bilge pump controls, navigation and anchor light arrangements, or meter-related switching between shunts or current transformers.

It is a practical match for helm panels, cockpit panels, cabin control panels, and other low-voltage marine switch locations where salt air, vibration, and regular use are part of the environment.

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.
