I was wondering what type of float switch you guys are using when you wire pond fountains? I've got two of them I need to wire, and I want to use the float switch to shunt trip the feeder. The switch will be installed on a 4x4 that the fountain installer mounts his control module on. My concern is the durability of the various switches I'm finding. This thing will be exposed to the elements as well as lawn mowers and the like. It would seem to me that someone must make an enclosure that would protect the switch but still allow water to enter it if the water level ever gets that high.
