Contura switches are the standard rocker switches you see on most modern boat switch panels, trusted across the marine industry from small bay boats to offshore fishing machines. Their curved rocker design, interchangeable lenses, and backlit legends make it easy for the captain to identify and operate each function, even at night or in rough water. Built specifically for harsh marine environments, they are designed to handle vibration, salt, moisture, and UV exposure, which is why so many OEM builders and custom shops rely on them for long lasting, professional switch panels. Among the different brands on the market, Carling is one of the best known manufacturers when it comes to quality and consistency in this style of switch.
Switch Dimensions
Configurations
These switches are available in different pin configurations and operating functions to match the needs of each circuit. You will find options like 2, 3, 4, 5, 6, and even up to 10 pin layouts, depending on whether you are controlling a simple ON OFF load, a maintained ON ON function, or a more complex setup with independent backlighting, indicator LEDs, or multiple circuits in a single switch body. Operation types include ON OFF, ON ON, ON OFF ON, and momentary functions (such as OFF MOM or MOM OFF MOM) for applications that require spring loaded control.
Thanks to this flexibility, a panel built with Contura (Rocker) style switches can be set up to match the exact behavior you want at the helm, whether it is a simple light circuit, a dual function accessory, or a system that needs separate control of power, backlighting, and indicators in one clean, organized layout.
The following pictures show rocker switch wiring diagrams that apply to different solutions and scenarios. We’ll cover just a few of these setups as a quick reference. Always refer to the manufacturer’s diagrams for your specific switch to avoid wiring issues.
