  • Need on/off selector switch for mill accessory power

    I need to create and electrical panel for my milling machine. This will mount on the machine on the back or side and will supply power to dro, powerfeeds, light. I want to have a switch and was thinking that having a simple on and off selector switch mounted near the mill’s fwd/off/rev switch would make sense. I’d like the box to be small.

    Holy crap is finding a simple switch not at all simple. You have pushbutton, rocker, cam, selector.

    Has anyone sourced a simple 120v selector switch with an enclosure?
    I found this switch and an enclosure

    I am assuming for now that this is good for 120v and not a low volt switch. I will call Zoro on Monday.

    This cam switch looks like it would work but can’t an enclosure for it.

    Another option is to drill a 22mm hole in the metal enclosure that will house the 120v outlets and just bend over or around the machine to turn on all the 120v goodies.

    Any help is greatly appreciated. Thanks

    Why not a trip to the local hardware store/HD electrical department for an electrical box and a switch? For a nicer looking box I'd go with an exterior aluminum one.

      I just use a 6 outlet power strip w/switch.
      It may be too large for your application, but it works good for me.

      People say I'm getting crankier as I get older. That's not it. I just find I enjoy annoying people a lot more now. Especially younger people!!!

        Perfectly acceptable solution and often used. I have a little saw table setup like that. I never use it, but I have it. LOL.
        *** I always wanted a welding stinger that looked like the north end of a south bound chicken. Often my welds look like somebody pointed the wrong end of a chicken at the joint and squeezed until something came out. Might as well look the part.

          I made a power center for my mill a couple of years ago. The box was folded up from sheet aluminum. It mounts where the original smaller switch box went. The main switch was the one that came with the mill. I think I have less that $30 or so in the whole thing, mainly for the four smaller switches.

            I would use a standard, small electrical box from the local hardware store. Probably one of the ones with the rounded corners. Any number of switches will fit in it and there are cover plates available. Do not get the cheapest, contractor grade, switches as they are not good for higher currents. Get a $5 or $10 one.

            If you do not like using a standard switch, you can still use the box and a cover plate. Get a plain cover plate and drill or mill your own mounting hole in it. Buy the switch first so you can be sure that it will fit. Almost any manner of switch can be purchased from electrical and electronic suppliers. You can even find liquid tight ones.

            And if you look REAL close at an analog signal,
            You will find that it has discrete steps.

              That's what I use too. It's mounted on top of the DRO arm. My DRO, power feeds, lights and other accessories are simply plugged in. I can either turn all of them on/off at the same time by flipping the main power strip switch or (as I usually do)- individually by the devices' own switches.

                i always thought extra stuff on the mill used single phase 120?

                A light switch. Well, not the run of the mill switch. I think I paid 2.50 for it/

                All my 110-120 goes there. Not much current. It is CNC though. Yep, light switch. Been running that way from 2003. JR

                  I have an old 3-blade service box on the back of the mill fed with 240v from the breaker panel. From that, I have two standard 120v outlet boxes. One always live for a light and Z-feed and the other switched with the service box (DRO and Tach). The service box then feeds the two VFDs with 240v for the mill (mill and X-feed). The back of the mill faces a walkway so all I do is walk up and raise the handle on the service box.
