    I see lots of these Albright knock off things on Ebay with prices all over the map. Besides the famous Albright unit, are there other manufacturers that people have used long term with good results? If so, please post up and the cost. I know that my M10,000 winch have fulled excess of 600 amps under full load so hopefully a typical 500a unit can handle a short current spike of this magnitude.

    Thanks for your input.

    Ali, the Albright web site gives specs for theirs, including duty ratings and graphs of amperage versus time (in seconds).
    D.C. Contactors and Disconnect Switches - Albright

    Of course, the knock-offs have no such specs available.

    Having said that, the $100 knock-off I bought from Summit Racing and advertised as a Superwinch contactor has worked flawlessly on my Warn 8274 for many years, including some yuuuge pulls (a big diesel pickup with a 24' gooseneck trailer with a skid steer on it, out of a ditch and up a steep hill). The 8274 will take more than 500 amps on start-up, so the Summit unit has done pretty well I think.

    Edited to add:

    Here is the one I have; the price has gone up a little:

    That's not actually "solid state". It's just 2 heavy-duty SPST relays integrated into a single housing with shared terminals because it's specifically designed to perform a reverse-polarity function. And even the cheapest ones can be rebuilt. Usually, the contacts just get corroded by their own ozone, pitted by the arc when they open, and scorched by the resistance through the corrosion & Carbon during hard pulls. A few passes with sandpaper or a needle file brings them back to almost-new.

    Solid-state components have no moving parts, and a solid-state relay capable of DC500A would cost a few hundred dollars. It would take probably 20 of these to do what the one 1911 posted does:
