Many years ago, when I was young and didn't know better, I installed a pair of fog lights and a switch to control them. It wasn't very long before the fog lights no longer worked and the culprit, of course, was the switch.
I learned then a switch is a good way to control a low current circuit or relay, but use relays whenever it's necessary to handle a higher current. That's not only more reliable, but safer as well.
