  • Replaceing Lathe Switch

    Last night the fourth on-off switch went in my Steel City Lathe. In the past whenever this has occured they have sent me a new one with no questions asked and told me that each one is a better one than the last. According to what I have read on-line this is not a problem limited to Steel City. Apparently Jet has experienced similar problems. I have taken all the switches apart and cleaned them while wating for the new ones to arrive but they only last a couple days. Contacts are burned and some type of lubricating grease is smeared everywhere. I need to find a permanent solution. My lathe is down and I have chair legs and stretchers to turn by wednesday.

    The switch has spades on the back and a mating female push-on connector on the wires to the lathe motor. Can I connect wires to a switch and then connect the wires from the switch to the wires on the lathe using push-on connectors? Or are push-on connectors only used to connect wires to switches? Will just a regular household light switch work for now?

    Numbers on the switch are:
    20/12A 125/250V
    _________________
    10(8)A
    250V~ 5E4
    IP54
    I don't know what the numbers mean except I think they indicate the switch is rated for household current.

    Thanks,Tom

    Yes you should be able to use a household switch for your lathe, just try to get one with the highest amp rating you can as it affords less resistance.

    I wired a regular house switch for my lathe, believe I used a 25amp light switch and works well for this 12" Atlas made for Craftsman...

      I didn't know light switches were rated. I will be sure to look for the rating.

      Thank You,

        Keep in mind using a light switch can be dangerous as it could be easily turned on by accident by bumping it.Install it in a location to avoid accidental starts.

          Agreed, my switch is mounted on the side of the bench to the left of the lathe.

            Tom,

            Even if you do use a light switch for now, you might want to take a look at the Grizzly site. They have various ratings of safety switches, and also magnetic switches.

              Thank you for the heads-up. I never thought of that. I often have neighborhood kids around my shop making things. I will have to come up with a better soultion than a wall switch as a permanent solution.

                Charles,

                Thank you. I will check their site. I don't know what a magnetic switch is.

                I was able to rebuild one of the bad switches and make it work, so I am OK for now. But past experience tells me it is just a matter of time before this switch goes bad. I gotta get those legs and stretchers turned. I say that and here I am typing when I should be out there turning.

                  Which switch do you need, the OR71646 (BOM Item 112)
                  or the OR 71657 (Item 210)?

                      When you turn a magnetic switch on it is held on by an electromagnet. When the power is cut, the magnet lets go and the machine turns off. When you reconnect the power it stays off. A regular switch will turn back on when you reconnect the power (e.g., after resetting a breaker, your lathe won't start up if you forget to turn it off).

                        I am not quite sure I undestand yet. I am using my machine and a breaker trips. The magnet lets go. I reset the breaker and the machine won't start because the magnet has not energized. How do I restart my machine if the switch doesn't work? Is there a mechanism within the switch that will actuate the magnet if I flip the machine switch from the on position to the off position and then back to the on position?

                          The switch still works, but it "defaults" to off after losing power (compare it to your light switch or a regular switch, which just connects the two wires; which will default to whatever it was before your lost power).

                            Got it. With all the young folks working in the shop it seems a magnetic switch is the way to go.

                            Thank you.
