    The rule super switch, or any rule switches build in the last 10 years are worthless. I redid all my bilge pump system 5 years ago with 5 new 3700s, rule switches, new wiring, new alarm panel etc. I have already replaced 2 of the switches, one of which burned one of the pump by constantly sending some low voltage to the pump

    the only switches I use now are ultra switches. Yes they’re almost three times the price but worth it. Some of them are 15 years old on the lazzara 110 I run and still working great

    Been using these for well over a decade after learning all the "big name" ones were crap. Made here in Florida and when the oem vessel wires were different then the paperwork diagrams that came with the Ultra Switch, a call to the company brought the owner on to quickly trouble shoot. Not cheap but IMO worth it.

    I'm not sure if/how easily you can find them in the US, but these folks build some bulletproof diaphragm pump for nautical applications.
    Short of bricks, they can suck just about anything from bilges - or holding tanks, whatever.
    Capacity of the attached models goes from 400 to 1900 GPH, but they may build also larger ones, IDK.

    Of course they are larger/heavier/more expensive than those Rule toys, because, well, toys they are not.
    But as opposed to submersible pumps (in reply also to CJ comment), they can be placed wherever convenient, routing just a hose with its suction strainer to the bilge bottom.
    Being fully self-priming, they will pick up to the last drop of water regardless of placement.

    The switches topic instead was already debated in this old thread, just in case anyone is interested.

    Must have been a design change between 2005 and 2008 hulls switching the discharges from the stern quarters to the transom.

    I have seen those "Ultra Switches" on many commercial ships I have worked on. Very simple and it looks like they have brackets to hook right onto the bilge pump they are servicing. Thanks for the info on those float switches.

    Sorry my friend, I read American (south/eastern). That PDF does nothing for me.

    IMO, they are a great switch, just leaves more water in the bilge. Kind of counter to the thread?

    More details are available in their website, of which there's also the EN version.
    And according to which, Maritime Diesel Electric in Tamarac is one of their distributors.

    BTW, they just announced also a cable reel system, though I guess it'll be hard for them to compete with Glendinning in their home Country...
