Contura DPST OFF-ON Black Switch

The Contura DPST OFF-ON black switch by Blue Sea Systems is a double-pole single-throw (DPST) switch. It is specifically designed for controlling electrical circuits on board vessels and provides reliable on-off functionality. Its actuator is black and features the Contura III style.

The abbreviation "DPST" stands for "Double Pole Single Throw." This indicates that the switch can control two separate electrical circuits simultaneously, with a single position for activation (ON) and a single position for deactivation (OFF).

The primary function of this switch is "OFF-ON" (off-on). It allows activating or deactivating an electrical circuit by toggling the actuator between these two positions.

The actuator of this switch is black in color and features a Contura III style, typical of Blue Sea Systems marine switches.

This switch is commonly used in marine environments for controlling various electrical circuits on board vessels. A typical application example is the control of navigation lights.

Yes, this switch is specifically designed to withstand harsh marine environments. It is resistant to vibrations, shocks, thermal shocks, moisture, and salt spray, ensuring reliability at sea.

The operating temperature range of this switch is from -40° C to 85° C, allowing it to function effectively across a wide range of climatic conditions.

Yes, this switch includes an LED that lights up when the switch is in the "ON" position, providing a clear visual indication of the circuit state.

The LED integrated into the switch has an estimated average lifespan of 100,000 hours, ensuring a long period of use without replacement.

The operating current required to power the switch’s built-in LED is 18 mA.

The weight of the Contura DPST OFF-ON black switch is 0.04 kg (approximately 0.09 lb).

The country of manufacture for this switch is Mexico.

This switch is compatible with 12 V and 24 V electrical systems. It can handle a maximum amperage of 20 A at 12 V and 15 A at 24 V.

Yes, this switch is equipped with ignition protection and complies with the ignition protection requirements of UL1500 and ISO8846 standards. This makes it safe for installation aboard gasoline-powered boats.

Yes, this switch is specifically designed to be mounted on Blue Sea Systems’ waterproof panels, ensuring optimal integration and sealing.

To ensure protection against water and moisture, the switch is equipped with an internal and external sealing gasket.

For a safe installation, it is critical to use fuses and cables sized appropriately for the specific application. This ensures that the maximum allowable current of the switch (20 A at 12 V, 15 A at 24 V) is respected and that the circuit is protected.

The switch can handle a maximum current of 20 A when the system is at 12 V, and 15 A when the system is at 24 V. It is critical to size fuses and cables correctly for the application to avoid exceeding these values.

Yes, this switch is specifically designed for simplified installation on Blue Sea Systems watertight panels, allowing for easy integration and a clean finish.

This switch meets the ignition protection requirements of UL1500 and ISO8846 standards, which is essential for the safety of marine electrical installations, particularly on gasoline-powered boats.
