Contura SPST Off-Momentary Switch

A "momentary off" switch means it is normally in the "ON" (closed) position. When you press the actuator, it temporarily switches to the "OFF" (open) position. As soon as you release the actuator, it automatically returns to its initial "ON" position. It is also referred to as a normally closed (NC) momentary switch.

SPST stands for "Single Pole, Single Throw". This means the switch controls a single electrical circuit and has two positions: open or closed. It functions as a simple on/off switch for a single current path.

This switch is a rocker type (rocker switch). It is operated by pressing one side of the rocker to change its state, then it returns to its initial position once released.

Yes, the Blue Sea Contura switch is specifically designed for marine environments. It is made with UV- and corrosion-resistant materials, ensuring reliability and durability in these conditions.

The Contura series switches are known for their robustness, resistance to harsh marine environments, and compatibility with standard panel cutouts. Their design allows for easy installation and seamless integration with other equipment in the same series.

This switch is ideal for applications requiring temporary activation of an "OFF" function. For example, it can be used for circuit testing, resets, or to momentarily cut a signal or equipment that is normally powered.

Blue Sea Systems switches are designed for long service life in demanding marine conditions. While an exact lifespan in number of cycles is not specified, their robust construction and high-quality materials ensure excellent long-term reliability.

The Contura series switches are designed to be splash-resistant and resistant to projected water, making them suitable for use in cockpits or other exposed areas of boats. However, they are generally not designed to be submerged.

This switch is designed to operate with 12V DC and 24V DC electrical systems. It is important not to exceed these voltages to avoid damaging the switch or the circuit.

The switch can handle a maximum current of 20 amperes (A) at 12V DC and 15 amperes (A) at 24V DC. It is critical to respect these values to ensure the safety and proper operation of the installation.

No, this switch is specifically designed for 12V or 24V DC (direct current) systems. Using it with AC systems could cause malfunctions, damage, or safety hazards.

Yes, as it is a switch from the Contura series, it is generally compatible with the label holders, caps, and modular mounting frames designed for this range, allowing for customization and aesthetic integration into the dashboard.

The standard cutout required in the panel for installing this switch is approximately 21.08 mm x 36.83 mm (0.83" x 1.45"). It is recommended to verify the exact specifications with a template before making the cut.

The switch is secured with a snap-in system. Simply press it firmly into the panel cutout, and side clips will hold it in place without requiring screws or additional tools for mechanical attachment.

During wiring, ensure the circuit is de-energized. Use wires with an appropriate gauge for the intended amperage, and make sure all connections are clean, secure, and insulated to prevent short circuits and corrosion. It is also recommended to install a correctly rated fuse upstream of the switch to protect the circuit.

No, this switch is designed to be mounted directly into a standard panel cutout via its snap-in system. However, modular bezels or mounting frames can be used if you wish to group multiple Contura series switches or for a specific aesthetic finish.
