Contura SPST Off-On switch black

An SPST switch, or "Single Pole Single Throw", is a type of switch that controls a single electrical circuit. It has two positions: open (Off) and closed (On). When the switch is in the "On" position, it establishes the connection and allows current to flow. In the "Off" position, it interrupts the connection, cutting off power to the circuit.

This switch is designed to turn a single electrical circuit on or off aboard your boat. It is ideal for controlling simple equipment such as interior or exterior lighting, bilge pumps, fans, or other devices requiring binary switching (on/off).

The Contura SPST Off-On switch is black, allowing it to blend discreetly into most marine dashboards and switching panels.

This switch is designed for flush mounting in a panel. It fits into a standard rectangular cutout, typical of Contura series switches.

The switch is made from marine-grade thermoplastic materials, resistant to UV and harsh marine environments, ensuring enhanced durability and reliability.

Yes, when correctly installed in a panel with an appropriate gasket (often supplied with the panel or sold separately), the Contura switch can provide protection against water spray and dust, typically achieving an IP66 rating on the front face.

The Contura switch requires a standard rectangular cutout of approximately 21.08 mm in width by 36.83 mm in height (0.83" x 1.45"). It is always recommended to verify the exact dimensions on the technical drawing provided with the product or on the manufacturer's website before drilling.

The switch is equipped with quick-connect terminals (faston or spade connectors) at the rear. You will need to use compatible female spade connectors (typically 6.3 mm) to connect the power and load wires. Ensure you respect polarity if required for your circuit.

Yes, this switch is designed to be compatible with marine electrical systems operating at 12V DC and 24V DC. Its current capacity varies depending on the operating voltage.

The Contura 8282-BSS switch has a maximum current rating of 20 amperes at 12V DC and 15 amperes at 24V DC. Exceeding these values will compromise the safety and longevity of the switch and the circuit.

Yes, the Contura switch is designed to integrate perfectly into the frames and mounting panels of the BLUE SEA Systems Contura series, enabling modular and consistent installation.

Although designed for marine environments, this switch can be used in other 12V or 24V DC applications such as recreational vehicles (RV), motorhomes, or off-road vehicles, provided voltage and current specifications are met and the installation environment is suitable.

For installation, you will generally need a drill with a suitable bit for cutting, a file or cutting tool to refine the opening, a crimping tool for wire terminals, and possibly a screwdriver to secure the panel if necessary.

While the switch itself is a simple component, the wiring diagrams specific to your application should be prepared based on your installation. For a SPST Off-On switch, the wiring is straightforward: one terminal for the power input and the other for the output to the load.

Contura switches are modular. It is often possible to replace the actuator (the visible rocker part) if you want to change the color or legend without having to replace the switch body and wiring.

An SPST switch itself is generally not polarized, meaning current can flow in either direction when the switch is closed. However, it is always recommended to respect the polarity of your circuit (positive/negative) for proper operation of the connected equipment.

Yes, being a BLUE SEA Systems product, it is specifically designed to withstand marine environments, including exposure to salt spray and humidity, thanks to its corrosion-resistant and UV-resistant materials.

To ensure waterproofing, it is essential to use a sealing gasket or an O-ring behind the panel when installing the switch in the cutout. Some Contura switch panels are also designed to improve the overall waterproofing.
