Help with new switch for chinese 3-1.

Tried to turn on the lathe the other night but switch would not click/seat in either forward or reverse position.
I found a melted wire connector and repaired but still nothing.
Purchased a new switch from littlemachineshop.com,after an hour searching was the only one I could find.
Rating is the same,but it has one less row of contacts(3 contacts per row) than my original.
The part number seems to reflect this (original= HZ10-10p/4 new=HZ10-10p/3)
I have been unable to find a diagram corresponding with what it looks like i'm working with,and don't fully understand they way these switch polarity.
Can I use this switch or do I need to track down a different one?

If somebody has a diagram or can assist in the wiring or where I can get a correct replacement F/O/R switch I would very much appreciate it.
I'm posting several pictures that will hopefully help in identifying the switch,lathe or proper diagram.
Two wires appeared to have been unused/disconnected,these could be to the light that does not work as i've never investigated why it doesn't.


Photobucket is giving me fits,so here is an old pic of the machine and maybe someone has an idea or diagram.
More detailed pics of old switch,wiring and new switch to follow.

You mean the rotary switch? Maybe the PDF of the brochure in this archive will help.

Perhaps a reader can answer the question, but the OP has not made an appearance on this board since 2013. We have no idea how he solved his problem at this point.

Just to update this post I sent an email to Grizzly and they got me a correct replacement part number and a schematic for replacing my switch.

I thought I would share just in case anyone else should run across this post in the future.

I have not received the switch yet. I just placed the order and will update after installed.

Thanks

This is good to know. My ShopMaster switch has acted up on occasion and it's probably the same.

I've added limit (reed) switches to my table that work with a "contactor" and sometimes when I'm working on something, I leave the power switch in the on position and shut it off at the contactor to save the switch.

Thanks

Well everything went perfect. I had to make some very simple modifications to the face plate to accept the screws from the new switch. I drilled 4 holes in the metal plate. I also had to trace the wires back to the motor to see which wire was which but it didn't take to long.

A big thanks to the rep at Grizzly that helped with the part and the schematic.

If anyone has any questions just ask. I will check back on this post on occasion.

To add some additional information here. All of the wires coming from my motor were black and I had to open the connection box on the motor and look at the very tiny lettering next to each connector to find the V1, U2 and so on.

In addition to this I just noticed after using the lathe multiple times since, that the face place of the switch is backwards FWD | OFF | REV instead of REV | OFF | FWD not a big deal and I am not sure that the plate doesn't have a reverse side or that it didn't come with an additional plate and I just missed placed it. Could also be that I missed wired for this switch, but I remember forward being to the right and reverse being to the left... at least I think!

Sorry, if this isn't much help but thought it was useful information so I wanted to pop back in and mention it.

Now I just need some FWD, REV stickers to place over the current so i don't accidentally start in the wrong direction.
