Any of the marine grade switches are going to be fine and will handle any current you can throw at them as they are made to stand up to starting current for big diesel engines. I would recommend going that route for one hat is going to be exposed to the elements. A lot of people go cheap at Harbor Freight or the local parts house. Some are happy with these, others not so much, but then I'm always amazed at the people who spend thousands on their truck and trailer, then wince at something that costs more than $20. Very few people have been unhappy with buying the best, and the best is barely good enough.
