Common Concerns Answered
What if I need to replace just the actuator on an older Contura switch?
Blue Sea Systems offers a range of replacement actuators for their Contura line to ensure continued functionality and maintain the aesthetic of your control panel.
Are the LEDs bright enough for direct sunlight?
While the LEDs are rated for 100,000 hours, their visibility in extremely bright, direct sunlight may vary. Consider secondary indicators if this is a critical requirement.
Is the price justified compared to generic switches?
The elevated price reflects the critical ignition protection (UL1500/ISO8846) and marine-grade construction, which are essential for safety and long-term reliability in coastal and offshore applications, far exceeding the performance of generic alternatives.
Frequently Asked Questions
What is the difference between DPDT and SPDT switches?
A Single Pole Single Throw (SPST) switch has one input and one output and can only open or close a single circuit. A Double Pole Double Throw (DPDT) switch has two inputs and two outputs, allowing it to control two separate circuits simultaneously or switch one of two inputs to one of two outputs.
What does ON-ON mean for a switch?
An ON-ON switch has two stable positions. In each position, it completes a circuit. This means it can be used to switch between two different connections or configurations, unlike an ON-OFF-ON switch which has a neutral OFF position.
Is this switch ignition protected?
Yes, this Blue Sea Systems Contura switch is ignition protected and meets the stringent UL1500 and ISO8846 standards, making it safe for use on gasoline-powered vessels where flammable vapors may be present.
What are the applications for a DPDT ON-ON switch?
A DPDT ON-ON switch is ideal for tasks such as switching between two different antennas, selecting between two different load banks, or routing power between two separate circuits, such as switching between shore power and generator power inputs to a single breaker panel. It's also commonly used for switching between current transformers (CTs) with a single meter.
What are the dimensions of the Blue Sea Contura Switch DPDT Black - ON-ON?
The exact panel cutout and overall dimensions can be found in the product manual linked above; however, Contura switches are designed for standard marine panel cutouts, typically around 1.45 x 1.06 inches.
