Need to replace electrical switch on my 818P Jet metal bench lathe with milling head

The original switch has six buttons. These are for

forward phase one
reverse phase one
off
forward phase two (twice the speed of phase one)
reverse phase two (twice the speed of phase one)
mill on and off

This is a 1980 model lathe that I acquired in 2010. When I got it the phase two switches did not work which was not the end of the world, but now the mill switch has ceased to work. The phase two switches do nothing when pushed, but the mill switch will run the mill if the switch is held down, but will not stay on otherwise.

I would replace the switch in a heart beat, but I don't believe a direct replacement is available. I would also replace the switch with another with similar functions, but I don't know electrical switches well enough to know what to get and how to wire it. I would also consider modifying the existing switch just so the mill switch would hold in the on position, but I would love to have the phase two on the lathe if the motor is still capable of doing it.

Also, wondering if there is some sort of forum with discussions on older Jet metal lathes.

Thanks for any thoughts on this. Jim

You didn't read & understand this ?

If my interpretation of your post is correct, you actually mean you have two speed motors? Using phase one/two terms when talking about electrical motors and switches confuses the hell out of everyone else. Just take the failed components into a proper industrial electrical supply and repair shop. If there's comparable switches still made they'll know what you need and can get them. Or how to adapt what is available to make everything work, that's what there in business for and do every day. Pay whatever that costs for professional level help when you don't know enough on your own. When I needed a stent implant I chose a qualified heart specialist to do the job since I was pretty damn sure I didn't know enough to do the same.
 
Well so is mine, but that didn't stop me from making a 5 hr round trip to take my 3 ph mill motor into an electrical supply, get there recommendations for what would work best, order and then repeat the same trip to go pick up an industrial level VFD. One way or another you will have an industrial rated electrical company in your area, call them and ask if they can help.
