That's how I installed mine. Not sure it's the "right" way, but it is "my" way and it works just fine. I have a small pull switch which is fine, but I do wish it had a light in it that would light when "on" just as a reminder that it needs to be turned off. Don't know for sure if a switch like that is out there though. What brand pump did you find? I think mine is a "Mr. Gasket". Pretty inexpensive as I recall.
