Hey folks.
That General lathe I snitched from the Highschool is now installed in Dad’s shop and we swapped the motor for a 110 v from a 550v.
My question is how can I make the original switch work on 110. It is an electromagnetic switch. I think.
The first picture is of the front.
(in 550v mode) The second picture had the white wire on the bottom screw and the black wire on the top screw.
(550v mode)The third picture had the red wire on the bottom screw.
Any possibilities of getting this to work with 110v??? Or am I stuck to use a regular switch.

Jet should have gotten a Jet <G>.
From the looks of it I think that all you have a monetary NO and NC swtiches.
And it operated a separare motor starter/contactor/relay that might or might not have operated off of line or had a transformer and operated off 24 volts.
It is possible that you have a mechanical ON/OFF switch with I doubt it with the 4 contacts and jumper strap.
What does the label say. It is just out of focus.
What was wired between where the power came in and the motor?

Label is on first picture
There was a power breaker box on the back side of the machine. SO yeah I think I need to retrieve that box. Or just put in a toggle switch.

As others have mentioned that's a momentary switch. If you want to keep the switch for appearance's sake, it would be easy enough to wire it up with a heavy duty relay, so pushing the ON button would energize and latch the relay and pushing the OFF button would release the relay. This would also have the benefit of preventing the lathe from turning back on unexpectedly, if for instance the power went off and then came back on again.
Now you have my attention!!!!
I will take a picture of the relay box that came with the machine when I get home or tomorrow. See if it can be used on a 120v circuit."No doubt exists that all women are crazy; it's only a question of degree." - W.C. Fields
With that size lathe, a 1 or 1-1/2 HP motor wouldn't be out of line. But you can upgrade at some point.
So has Ian been drooling over the Lee Valley catalog much?
Ian has already figured out he is about $600 short for what he wants (That's after the gift cert!!!!!!)"No doubt exists that all women are crazy; it's only a question of degree." - W.C. Fields
Its good to have a goal <G>
yep, a relay would be the safest solution even an 8 pin plug-in relay would work, those things are rated for 12 A.better yet an SSR would be the cat's PJs.http://www.crouzet-usa.com/catalog/_gnip00.shtml < GN # 84134011 > I think ? zero switching and no moving parts and available finger-safe too about $30 US or $950 Cdn.

But to use it with that switch he the relay needs an auxiliary "contact" to maintain the circuit. If the push button can interrupt motor operating current then could be done without an auxiliary contact..

correct, but with the 8 pin it is just a simple matter of wiring the start button in parallel with normally open contactsthere are maintained pushbuttons that are also mechanically interlocked which would work too some of those have a lockable slider to prevent accidental starts..for liability jet should rewire it exactly the way it was manufactured ........

Yeah, I think it's a momentary switch (glorified doorbell button) that's intended to connect to a motor starter gizmo.
Probably the simplest thing to do is replace it with a standard toggle or rocker switch (though obviously you want a heavy-duty one, with a motor rating larger than your motor).
The breaker box "gizmo" that was on the back of the machine is at my house not here. Me thinks a toggle switch is the way to go."No doubt exists that all women are crazy; it's only a question of degree." - W.C. Fields
that IS a momentary start stop switch which you would have needed for the original Canadian 3ø motor.
I would add that if you are just going to use a toggle switch, get a guard for the toggle to prevent accidental operation and definitely use a motor starting switch that has an overload element to protect the motor.... you can get them from a supply house and everyone makes them, of course you will need to buy the proper overload element you choose from the chart that comes with the switch.

Thanks!
Gotta contact general anyway as we need the drive center for the head stock.
They may have a load protection switch for it."No doubt exists that all women are crazy; it's only a question of degree." - W.C. Fields
anytime !.

What size motor?What kind of motor? I have not seen any motors designed for woodworking tools and the like in 2 hp and under that are not internally protected and don't need motor starters with overload protection.PS You want a 115 volt motor for use on 120 volt systems. I know that Canadia is backwards, but not that backwards that they still have 110 volt electrical systems <G>.Although, about 40 years ago, I did have to figure quotes for a pump and motor to run on 25 Hz at a Canadain mine..

yeah call me an old fart!!!!! LOL
it is a 120v motor. I think it's a 1/2 horse.
Other than that well I'll have to go look at it."No doubt exists that all women are crazy; it's only a question of degree." - W.C. Fields
