Common Concerns Answered
Will this switch handle the amperage for my trolling motor?
The Blue Sea 7482 is rated at 15A @ 12VDC. For higher amperage trolling motors, consider a higher-rated switch or a heavy-duty relay system.
Is this switch suitable for offshore use where it might get wet?
While designed for marine environments, this specific model is not fully waterproof. For areas with direct water exposure, consult Blue Sea Systems' waterproof switch options.
Can I use this switch to control two separate lights simultaneously?
The SPDT ON-OFF-ON function allows you to switch between two different circuits, or to connect/disconnect one circuit. It cannot control two separate lights simultaneously; for that, you would need two separate switches or a DPDT configuration.
Frequently Asked Questions
What does SPDT ON-OFF-ON mean?
SPDT stands for Single Pole, Double Throw. The ON-OFF-ON designation indicates that the switch has three positions: one position connects the common terminal to the first throw terminal, the middle OFF position disconnects all terminals, and the third position connects the common terminal to the second throw terminal.
What is the maximum DC voltage this switch can safely handle?
This switch is rated for up to 32V DC, with a maximum amperage of 5A at this voltage. For higher voltage systems, alternative switching solutions are required.
How is this switch typically mounted on a boat panel?
The 7482 is designed for panel mounting, requiring a specific cutout size. Terminals are typically solder or screw-type for secure electrical connections.
What are the dimensions of the mounting cutout required?
Consult the product manual or manufacturer's specifications for the precise cutout dimensions to ensure proper panel fitment.
Is this switch suitable for engine compartments?
Yes, this switch is ignition protected, making it safe for use in potentially hazardous locations such as engine compartments where flammable vapors may be present.
