Enco 110-2032 switch wiring

[Crazed Dan]

I re acquired a lathe I bought new in 2000. It came back as a gift. It was never used and stayed in storage until I got it back a couple months ago.
I changed the transformer out and the temporary switches work but the other lever did not. I purchased a new switch but of course it's different.
I am at my a loss.
The attached photos show the old switch and there are some diagrams I've gotten as help but I'm still confused.
Any help is greatly appreciated.
Thanks Danny

Dan: wow- dormant for 22 years? That's gotta be some kind of record.
Let me take a look and see what's what

1) How is the new switch different than the old one?
2) Are the 4 wires from the lathe to the switch numbered 4,5,6 and 7?
3) Is it possible the old switch is still good? Is the part number still visible?

That'll do for starters...apparently the original switches on those machines have a special contact arrangement- hard to find a direct replacement
The Grizzly and the Enco don't always match up electrically

Sorry to have taken so long to respond but my cell phone hates the Hobby Machinist site software.

Awnsers:
1: The new switch is slightly larger with eight connection point vs 4 in the old switch.
2: No, the wires are numbered 3,4,5&6.
3: The old switch shows no visible part number.
Before I removed the old switch it did show voltage at the connection points but there was zero response from the on/off rod/lever.
After removing the switch I decided to disassemble to check for obvious faults but the switch exploded during disassembly.
I've included more photos.
I really appreciate your help.
Thanks Danny

OK, next can you shoot some views of the inside of the control box/contactor box- I need to see which version you have

Here are some pics before I changed the transformer. The transformer was dead. Voltage in zero out.
Thanks Danny

Which Grizzly machine was the new switch used in?
Shoot me a pic of your control panel also- thx
I see an error on the factory diagram- your machine has a 24 volt control system so the transformer output should read 0- 24- 110 v not 0-240-110
I'm starting to understand how it worked originally- need a bit more cogitating

 

[Crazed Dan]

The grizzly was not mine. I'll try and find out what model but getting a pic of the grizzly control panel may be an issue but I'll get started.

 

[markba633csi]

I need a pic of your Enco control panel and secondly need to know which Grizzly model this piece of schematic matches to:
Also, do you have a multimeter that measures continuity (ohms)?

 

[markba633csi]

I don't believe you can use the new switch, we can ring it out with a meter but my hunch is it won't be a drop-in replacement.
Your original was a custom switch with normally closed contacts in the "0" or middle position apparently.
Some lathes were equipped with a single cylinder switch and some with a pair of microswitches for the forward/reverse lever.
You might be able to find a cylinder switch of the proper type. The other option is to install a pair of microswitches and a cam from the
forward/reverse lever. That would probably be my choice. Most of the more modern lathes use the microswitch approach.
Let me study it for another day and see if maybe we can kluge the switch somehow- maybe some electrical magic is possible

See the attached pics. This is from the grizzly that the switch like I have was installed. My multi meter is dead. If I really need to I can buy another.
