    I'm in need of a replacement for a failed Vacuflush vacuum switch and happened on this while shopping: https://theflushguard.com
    Claims to monitor the vacuum and shut off the pump if a leak is detected. If it does, simple power recycle will enable the next flush. Direct (and seemingly easy) replacement for both kinds of Dometic systems. Price is about the same or even less than the Dometic part.
    Has anyone tried this?

    Interesting. I've got a vacuum switch on order right now since mine has also failed. I have had a few times where the pump continued to run, so I've made it a habit to shut off the system between flushes. This looks like a good solution for that problem.
