Rofi ON-OFF-ON einhleypis (SPDT) BLUE SEA Contura svartur

An SPDT (Single Pole Double Throw) ON-OFF-ON switch is a type of switch with a single pole (one input) and two distinct outputs. It allows switching power between three positions: an ON position for the first output, a central OFF position (neutral) where no output is powered, and a second ON position for the second output. This makes it ideal for controlling two different functions from a single power source.

This Blue Sea Contura switch is designed for 24V DC electrical systems. It is optimized for this voltage to ensure optimal performance and reliability in marine environments.

The BLUE SEA Contura SPDT black ON-OFF-ON switch has an IP44 protection rating. This means it is protected against solid objects larger than 1 mm (such as dust) and against water splashes from all directions, making it suitable for marine environments where it may be exposed to moisture and spray.

Thanks to its ON-OFF-ON function and robustness, this switch is ideal for various marine applications requiring toggling between two functions or two separate power sources. For example, it can be used to:

Switch between navigation lights and anchor lights.Control two different pumps.Select between two auxiliary circuits.It is perfect for boat dashboards, control panels, or any marine electrical installation requiring reliable and simple control.

Installing this Contura switch requires a specific cutout in your panel. You will need to make a rectangular cutout with precise dimensions so the switch fits correctly. Once inserted, it is usually held in place by integrated clips on the sides. For wiring, the switch has three terminals for connection (one common input and two separate outputs for the ON positions).

This Blue Sea Contura SPDT black ON-OFF-ON switch is rated for a maximum current of 15 amperes (A) at 24V DC. It is critical not to exceed this rating to ensure the safety and longevity of the switch and your electrical system.

This SPDT ON-OFF-ON switch has three connection terminals. One terminal is the common input (the pole), and the other two are the outputs corresponding to the two distinct ON positions of the switch.

Yes, this switch is part of BLUE SEA's Contura series, known for its modular design. It is compatible with a wide selection of mounting brackets, bezels, and dashboard accessories from the same range, enabling seamless aesthetic and functional integration into your existing or future control panel.

The weight of this BLUE SEA Contura SPDT black ON-OFF-ON switch is approximately 0.04 kilograms (40 grams). It is a lightweight component, easy to handle and install.

This switch is black, offering a discreet and professional aesthetic that integrates easily into most marine dashboards.

This is a Contura series rocker switch (rocker switch). Its ergonomic design allows easy toggling between ON-OFF-ON positions.

To cut the recess, refer to the provided cutting template or the precise technical dimensions. Typically, a rectangular cutout is required. Use an appropriate tool such as a hole saw or a file to achieve a clean and precise opening, ensuring a perfect fit for the switch.

Blue Sea’s Contura series is renowned for its robustness, reliability, and modular design. Advantages include:

Excellent resistance to marine environments (water spray, dust).Easy installation thanks to standardized dimensions.Compatibility with a wide range of mounting accessories.Professional and integrated aesthetics for dashboards.

Yes, Blue Sea Systems switches, including this Contura model, are specifically designed for marine environments. They are manufactured with corrosion-resistant materials to ensure long service life and reliable performance even in the presence of moisture and salt air.

For a secure and reliable electrical connection, it is recommended to use the appropriate-size spade (faston) terminals for the switch pins. Ensure connections are properly crimped and insulated to prevent short circuits or corrosion.

This switch can be integrated into safety circuits for non-critical functions. However, for primary safety applications or critical systems, it is always recommended to consult a qualified marine electrician and comply with the safety standards specific to your vessel.

The main difference lies in the number of positions and outputs:

A SPST (Single Pole Single Throw) switch is a simple ON-OFF switch. It has one input and one output, allowing a circuit to be opened or closed.A SPDT (Single Pole Double Throw) switch, like this model, has one input but two outputs. It can switch power between the first output, the central OFF position, and the second output.The SPDT therefore offers more versatility for controlling multiple functions with a single switch.
