Contura SPST Off-Momentary Black Switch

This switch is an SPST (Single Pole Single Throw) model with an OFF-(ON) momentary action. Its main function is to provide a temporary electrical contact, meaning it activates a circuit as long as it is held in the ON position and automatically returns to the OFF position once released.

« SPST » stands for « Single Pole Single Throw », indicating that the switch controls a single circuit. « Off momentary » (or OFF-(ON)) means the switch is normally in the « Off » position and only switches to « On » while being actuated, returning to « Off » as soon as it is released.

This switch is ideal for marine applications requiring momentary contact, such as controlling sound signals (horns), windshield wipers, or other functions that only need temporary activation.

Yes, this switch is designed to resist salt corrosion. It includes internal and external panel sealing gaskets, ensuring good resistance to water and demanding marine conditions.

The required mounting hole for this switch is approximately 36.83 mm x 21.08 mm (1.45 inches x 0.83 inches).

Yes, the Blue Sea Contura switch is ignition-protected, complying with UL1500 and ISO8846 standards. This makes it safe for installation on gasoline-powered boats.

This switch is designed to operate across a wide temperature range, from -40°C to +85°C, making it suitable for various marine environments.

This Blue Sea Contura SPST Off momentary switch is black in color.

The switch integrates internal and external sealing gaskets for the panel, ensuring its water resistance. The product information does not mention the inclusion of a separate protective cap or cover.

Yes, the design of this switch makes it resistant to vibrations, shocks, and thermal shocks, which is essential for demanding marine environments.

This switch is designed for DC circuits. It can handle a maximum current of 20A at 12V DC and 15A at 24V DC.

Yes, this switch is compatible with 24V DC circuits, with a maximum capacity of 15 amperes.

No, this switch is specifically designed for DC (direct current) circuits and is not recommended for use with AC circuits.

The switch is specifically designed for installation in water-resistant panels and Blue Sea Systems switch mounting panels. While it can be mounted on other panels that meet the cutout dimensions, optimal waterproofing is ensured with compatible panels.

Installation requires cutting a hole approximately 36.83 mm x 21.08 mm (1.45" x 0.83") in the panel. The switch is then inserted and secured. Its internal and external sealing gaskets ensure good water resistance once installed.

For the physical installation of the switch, you will generally need:

Measuring tools (ruler, caliper) for marking. A cutting tool suitable for your panel material (hole saw, Dremel, or jigsaw with a fine blade). Wiring tools (wire strippers, terminals, crimping tool) for electrical connections.

Yes, electrical components on a boat must always be installed by someone with marine electrical knowledge to ensure safety and proper system operation. It is important to follow the appropriate wiring diagrams and applicable safety standards.

Yes, this Blue Sea Systems switch is covered by the manufacturer's standard warranty.

The packaging contains a Blue Sea Contura SPST Off momentary black switch (reference 8292-BSS). Mounting or wiring accessories are generally not included unless the manufacturer specifies otherwise.

The switch is supplied as a standalone component. Detailed wiring diagrams for integration into a specific system are typically not included directly in the switch’s packaging. It is recommended to refer to marine electrical wiring standards or consult a professional.
