onoahimahi, yes it was a Rule Heavy Duty switch. Got it replaced under warranty from WM so good to go. I hope they are not going to start failing like this. If one more goes, I will look to replace all 3 on board with another brand. I have had great success over the 30 years of boating with the Rule pumps. I have had a few float switches go bad, even the mercury one's. Mostly in the past was due to corrosion from electrolysis. I see no signs of this on the Grady. The wiring was clean and looked new. Connections were high and dry and I use the heat shrink butt connectors with the glue that oozes out to seal them. I think this was just a bad switch internally somehow.
