Bilge pump float switch

[Skag]

I have an Ultra switch for my shaft sump and love it. However, I have another low spot in the forward section of the engine room (that should never ever have water) that I want to put a high water alarm switch. What is the consensus on these solid state switches? Link to one that looks great - Seaflo 20amp rated. I just need it to power my high water alarm.

This is a neat concept and it looks good as presented here. In my experience, the switch was a total failure. I had installed one in my aft lazarette. Water that accumulates in the lazarette is basically rain water -- not salty ocean water. Fresh rain water does not activate the switch. Only way to evacuate the rain water was by pushing the manual activation lever.
