This is the switch I have been using as the Wind Protection Mode toggle switch in my Sun Harvester Shield circuit.
It's nothing fancy, just a simple switch that was chosen simply because it was the cheapest that I could find.
Note that you can leave the Wind Protection Mode switch disconnected from the shield if you wish. It won't hurt anything. You just won't be able to go into Wind Protection Mode.
