The switch is nice for summer nights when you you have your windows open and can hear the turbine start up in gentle winds. Flip the switch and the turbine will spin silently.
You could cut the power with a breaker but then the turbine will spin for a seconds or two and break, causing a thump and undo wear on your turbine.
This product didn't come with any documentation. If you guess the plus and minus connections and don't get it right you'll end up melting your switch. I should note that the location of the plus and minus connectors can be found in the Air Breeze manual but not on the switch.
