Nilight NAV/ANC Rocker Switch 7Pin — DPDT, 12/24V
The DPDT rocker switch provides three positions: ON – OFF – ON, allowing independent control of two loads. It’s rated for 20A at 12V DC and 10A at 24V DC, making it suitable for navigation and anchor lighting circuits. Its universal fit works with marine boats, yachts, cars, and trailers, among others. The switch is designed for easy installation and replacement on existing panels, and its durable plastic construction with well-conductive pins supports long-term use.
Best for: Boat owners who need to replace a standard navigation/anchor light switch without reconfiguring the panel. Better for two-load setups where both nav and anchor lights must be controlled from a single unit. Caution: Verify panel compatibility and mounting hole size before purchase, as the unit is sized for common 7-pin DIN layouts.
Nilight NAV/ANC Rocker Switch 7Pin — DPDT (Another Variant)
This second Nilight option shares the same DPDT design and power ratings, supporting 12V/24V systems with three positions for navigation and anchor lights. It’s described as easy to install and suitable for replacement on original panels. The switch uses durable plastics and conductive pins designed for steady performance in marine environments.
Best for: Users updating an existing switch panel who want parity with other Nilight components. Choose this if you already use Nilight parts and need consistent fitment. Caution: Confirm the exact pin configuration in your panel to ensure seamless wiring compatibility.
BACAUTOPARTS Blue Led NAV/ANC 7PIN Switch
This blue-LED, 7-pin NAV/ANC switch offers a three-position control for navigation and anchor lighting. It features a laser-etched logo, a rugged metal and ABS plastic build, and a mounting footprint compatible with standard 37.2 mm x 21.2 mm hole sizes. The LED indicator enhances night visibility, reducing misactivation risk in low-light conditions.
Best for: Night operations where clear LED cues reduce misoperation. Better for installations that require a durable, logo-labeled face. Caution: LED brightness may vary with supply voltage; ensure power is stable to maintain legible illumination.
BACAUTOPARTS Red LED NAV/ANC 12V — 7PIN
This red-LED NAV/ANC switch emphasizes navigation light activation with up and anchor light activation down. It is rated at 20A/12V DC and 10A/24V DC, with a mounting footprint matching standard din sizes. The dual built-in red LEDs enhance readability at night, and the panel cover uses laser-etched lettering for durability.
Best for: Boats needing conspicuous, color-coded night indicators. Choose this if you want immediate visual confirmation of each light’s status. Caution: Red LED indicators can be less visible in bright daylight; verify installation orientation and lighting needs.
Attwood Marine 7594-3 Three-Position
The Attwood 7594-3 is a three-position push/pull switch offering Off, On, On. It is designed for reliable control of multiple components, including navigation lighting and related accessories. The large handle provides ease of operation, which can be beneficial in rough conditions or when gloved hands are involved.
Best for: Operators who want a straightforward, robust switch with tactile feedback and easy engagement. Better for setups where a push/pull action suits the boat’s control scheme. Caution: It is a toggle-style option, which may differ from rocker layouts in some panels.
Seachoice 3-Position Toggle Switch
The Seachoice switch provides three-position functionality (On/Off/On) with six terminals. It is suitable for running and anchor lights, bilge pumps, blowers, and other basic marine circuits. This option prioritizes versatility and compatibility with common marine wiring schemes.
Best for: Users seeking a dependable, widely compatible toggle option for multiple marine accessories.

Best for: Compact installations where space-saving is essential. Better for users who want a single switch to manage two lighting circuits. Caution: LED color and brightness can vary; confirm the LED behavior matches your panel’s expectations.
FXC 3 Way NAV/ANC Switch — Blue LED
This FXC NAV/ANC switch features a 3-position On/Off/On design with a 4-pin SPDT configuration. The upper LED marks NAV, the lower LED marks ANC. It is built with ABS and well-conductive pins, offering better water resistance and durability for marine environments. Mounting hole size is compatible with common boat installations.
Best for: Installers who need explicit, two-LED status cues for nav and anchor lighting. Choose this if you want clear separation between navigation and anchor indicators. Caution: Ensure the SPDT pin arrangement matches your wiring harness to avoid miswiring.
Buying Guide: Key Purchase Considerations
What lighting loads will you control? Choose DPDT or 3-position switches if you need independent control of two lights (navigation and anchor) from one panel. For single-load control, a standard 3-position toggle or rocker may suffice.
What are the mounting and footprint requirements? Verify mounting hole sizes (often around 37.2 mm x 21.2 mm) and face dimensions to ensure compatibility with your panel cutouts.
How important is LED feedback? Blue or red LED indicators improve night operation; laser-etched logos provide durability against the marine environment. Consider IP ratings and enclosure materials for durability in damp areas.
Is retrofitting easy? Look for switches marketed as replacement or universal fits. Replace-on-panel options simplify upgrades without rewiring.
What is the operating context? For saltwater boats, ensure corrosion resistance and reliable conductivity. Three-position designs help prevent accidental activation in rough seas.
