Frequently Asked Questions
What does SPDT mean for a marine switch?
SPDT stands for Single Pole, Double Throw, meaning the switch has one input (pole) and can connect that input to one of two different outputs (throws), enabling control of two separate circuits.
Can this switch be used for both positive and negative switching?
This switch is designed for switching the positive (hot) side of a circuit. Ensure correct wiring practices for marine DC systems.
What is the physical size of the panel cutout required for this switch?
The panel cutout diameter required for this switch is 0.50 inches (12.7mm).
What type of connections does this switch use?
This switch utilizes standard 0.250" quick connect terminals for easy and secure electrical connections.
Is this switch suitable for saltwater environments?
While designed for marine use, all electrical connections should be properly sealed and protected in harsh saltwater environments to prevent corrosion and ensure longevity.
