This appears to be a CubCrafters part number so I can't find it as source from the vendor.
Did you check to see whether this switch is rated for 15 amps or did you source another switch?
Also did you source the new 15 amp CB from the main bus rather than the EXT Main Bus. The EXT Main Bus has its own 10 amp CB before the original landing light CB?
