Contura DPST Off Momentary Switch Black

DPST stands for "Double Pole Single Throw". This indicates that the switch can simultaneously control two separate electrical circuits with a single action. It has two inputs and two outputs, which are activated or deactivated at the same time.

This Contura switch is black, allowing it to blend discreetly into most marine dashboards.

Blue Sea Systems Contura switches are typically made from robust UV-resistant thermoplastic materials, designed to withstand harsh marine environments, including exposure to saltwater and sunlight.

Yes, Blue Sea Systems' Contura switch range is specifically designed for marine environments. They are made from materials resistant to corrosion, salt water, and spray, ensuring durability in nautical conditions.

The switch is usually sold separately, designed to integrate into an existing support or panel such as a Contura. Mounting frames, rear brackets, or labels are generally not included and must be purchased separately if required.

A momentary switch (like this one) only maintains its activated position while it is pressed, then returns to its resting position once released. A latching switch, on the other hand, remains in the position it was set to until it is operated again to change state.

A DPST (Double Pole Single Throw) switch typically has four connection terminals: two for the inputs (one per pole) and two for the outputs (one per pole). This allows control of two independent circuits simultaneously.

Blue Sea Systems Contura series switches are designed to fit a standard cutout. The typical installation dimension is approximately 21.08 mm wide by 36.83 mm high (0.83" x 1.45"). It is recommended to verify the exact specifications on the manufacturer's installation diagram for precise cutting.

To wire a DPST switch, connect the two inputs (poles) to separate power sources or different phases of the same circuit, and the two outputs (throws) to the devices or circuits to be controlled. As it is "momentary Off", it will temporarily disconnect these two circuits when activated. It is imperative to follow the wiring diagram provided by Blue Sea Systems for this specific model to ensure correct and safe installation.

For Contura switches, it is generally recommended to use 6.3 mm (1/4 inch) quick-connect terminals (faston). These connectors ensure a secure and reliable connection, particularly in a marine environment.

Yes, Contura series switches are designed to be interchangeable in the same panel cutouts. If you are replacing another Contura switch, the process is generally straightforward, requiring only disconnecting the old one and reconnecting the new one while respecting the wiring.

Yes, this Contura switch is designed to be fully compatible with Blue Sea Systems’ Contura modular panel systems. It fits into the standard cutouts of Contura mounting brackets and housings, allowing easy customization of your dashboard.

Although this switch is specifically designed for marine environments, its robustness and weather resistance also make it suitable for other demanding applications such as automotive, off-road vehicles, or industrial equipment, provided electrical specifications (voltage, current) are respected.
