Sure Bail Float Switches

[MarkMuck]

I recently purchased a 1999 Silverton 392.
It has Sure Bail float switches. My understanding is there is no way to test them.
I don't like that. Are they pretty reliable or should I just replace them. My bilge is dry so it is not an issue now. Thanks

Not a fan of Sure Fail switches. BIG fan of Water Witches.

Sorry, inadvertently hit the submit button. As I was aying, I'm a BIG fan of Water Witches. No moving parts to jam up, break, or fail. Simply a sealed assembly with two contacts on the face of it. Senses continuity between them, such as from water, and closes the switch. FAR more reliable, in my opinion, than mechanical float switches.
