What is the latest thinking on reliable bilge pump switches

[Screen Saver]

I don't think voltage has anything to do with it.....

Perhaps I put it poorly. I'm not saying the voltage has anything to do with the fuse or internal failures of the rule float switch. But I am saying these high voltage 3 stage chargers (and i have them), which have been around for some time as you say are definitely pushing the limits of some of the electronic devices. Even LED's in some places are not lasting as long as they should due in part to the higher voltages. A few boats I know are fitting 12V regulators to a number of circuits to compensate for some of these top end voltages. Some of my electronic products will actually cut off, or in the case of some Ryamarine equipment it will start to switch to 24v when it see's 15v, and some inverters will disconnect. My Bose System shuts down at 14.9 volts. 13.8 +-10% is typically the tolerance and at 15V that's right on the edge, all be it just inside I agree.

My final fix.... for now. I really want to get an operating bilge pump system and I don't want to spend hours and days to create unique switches that would hopefully be more reliable.
So for now, or until the next failure, I have opted to install two Water Witch 101 12V switches. A low mounted one will control my pump, and a higher one will just activate an audio alarm.
I am going to mount these switches in a manner that provides easy access and replacement, just in case. I'll post a picture of my completed project.
