I use standard non electronic pumps and switches.
Since I have 5 bilge pumps, any one pump can fail and I have backups ready to work.
2 in one compartment, and 3 in another.
One pump's switch is set lower and is then the primary pump, the other switch sits higher and a third sits completely out of any bilge water. So failures of a lower in the water pump mean I have working backups.
They are all Rule pumps. I have taken apart old Rule pumps and even they still had not worn down their motor brushes past half way point. Every failure for me, with a bilge pump, has always been its water detection switch.
