Contura SPST Off-On Switch

This switch is designed for a simple "Off-On" (off-on) switching function. It allows you to activate or deactivate a single electrical circuit on board your vessel or vehicle.

SPST stands for "Single Pole, Single Throw". This means the switch controls a single electrical circuit and has two positions: open (Off) or closed (On).

This switch is compatible with 12V DC and 24V DC electrical systems, making it suitable for most marine and automotive applications.

The switch can handle a maximum current of 20 amperes at 12V DC and 15 amperes at 24V DC. Exceeding these values will compromise the switch's safety and longevity.

For installation, a standard rectangular cutout from the Contura series is required. Typical dimensions are approximately 21.08 mm (0.83 inches) in width by 36.83 mm (1.45 inches) in height.

This switch uses male quick-connect terminals (0.250 inch / 6.35 mm), enabling fast and secure wiring.

Yes, the Contura series switch is designed to be splash-proof and water-resistant. The front panel of the switch, once properly installed with a panel gasket (usually sold separately or included with the panel), provides IP66 protection.

The switch housing is typically made of marine-grade thermoplastic. The terminals are nickel-plated brass for good conductivity and corrosion resistance.

No, this switch is specifically designed and calibrated for direct current (DC) systems typically found in marine and automotive applications. Using it with alternating current is not recommended.

To wire a SPST Off-On switch, connect the positive power source (the "hot" wire) to one of the switch terminals, and the wire leading to the device to be controlled to the other terminal. The switch acts as a simple circuit breaker for that single wire.

The switch is usually sold separately. Caps, seals, and panel mounting plates are often sold as separate accessories, allowing for customization of the installation.

Yes, Blue Sea Contura series switches are specifically designed for marine environments, offering good resistance to corrosion, vibration, and spray when properly installed.

Yes, if the existing switch uses a standard panel cutout from the Contura series and the voltage and current specifications of the circuit to be controlled match the capabilities of this switch, it can be used as a replacement.

If the electrical load of your device exceeds the nominal rating of the switch (20A at 12V DC or 15A at 24V DC), it is mandatory to use a relay to protect the switch and the circuit. The switch would then control the relay, not the load directly.
