    Dagnabbit, I'm at work again and can't see the videos until I get home tonight.

    I have one lonely 3phase outlet in my garage (the legacy of the PO who ran a small business out of the garage), hence the need to put plugs on my machines. It's nominally 400v. And there's 230v single phase as well of course, for normal appliances. All 50 Hz.

    Hi Jack. Thanks for the videos.

    At present I have no intention of adding a VFD to any of my machines (I believe they're still horribly expensive over here). But I've been mulling over this video (the "2-wire control" video) as that's probably what I would need for a remote switch using ye olde electro-mechanical contactors.

    I note that you wired your remote switches in parallel. Can I suggest it would be safer to wire them in series - that way any switch activated in an emergency would switch off the power, rather than having to find the one you used to switch it on.

    I can imagine SWMBO answering yells to find me entangled in a machine (actually I prefer not to imagine that) and having to try all the switches before finding the right one .

    And not that I can imagine it in a small workshop, but consider an apprentice having a joke by switching on the other switch while you're using the machine. Then when you switch it off, it keeps running because it's still receiving a "run" command from the second switch. Dangerous I know, but I remember when I was an apprentice in the early 1970s - we (the other apprentices and I) used to get up to some dumb pranks .

    Cheers, Vann.

    Here's a nice stop switch that was on Gumtree (brought up by amrjon).











    The can gives an idea of scale, it's a nice substantial stop switch, cast aluminium body and turned brass mushroom button. Opening it up, I was happy to find some nice original switch gear, in what looks to be perfect condition. It has a nice lockout feature (where it can be pushed in, and twisted to lock down, a brass screw allows it to be locked in place).

    It came with some labels etc from a Wadkin EKA tenoner, so I am guessing it was a stop switch mounted on the sliding table (assuming it was also from the EKA

    Cheers,
