Yes, I own a Delta 46-460 Type I lathe. Yes, my On/Off switch gave up the ghost, today. I just finished changing the spindle bearings and replaced the drive belt and when I started finishing a bowl project the lathe just stopped. I fiddled with the lever and found the lathe would turn back on and then just turn off, fiddle some more and it would run for a bit more and then just shut off.
I commenced to disassemble the control box and was hesitant to take all the wires and stuff off their respective posts but it would be the only way I could get to the On/Off switch itself. After about an hour debating with myself if I should get this involved or just pull the switch and upgrade to a new larger lathe. I convinced myself that I had nothing to lose so I tore into it. A few pictures later, disconnect a few wires and then a few more pictures and wires disconnected I removed the reversing switch. I then proceeded on to the afore mentioned nemesis. I tried to be calm and collected but once the pry bar implement slipped and I ended up scraping the skin off the length of my thumb I'd had enough being a nice guy. I did overcome the holding mechanism on the switch body, to its own demise but I did prevail.
After I disassembled the switch itself I came to find out it is a simple double pole single throw rocker switch. I went online to eReplacementParts and ordered the type II switch as it has the same number of poles and the body looks very similar if not identical to the body of the Type I
Now the juicy stuff.
The switch is a "defond" ART
20A 125-277VAC
2HP 250VAC
1HP 125VAC
0910B
Reference the pictures.
The two 'legs' in the assembly picture rock as the red activator is moved
The rocking of the legs moves the contacts inside the body to make contact similar to how the points on an older model car engine work, see the inside the body picture.
Note all the wear on the two legs in the assembly picture. They have been made shorter over the years of rocking and no longer are able to move the contacts enough to activate the switch.
My guess would be that any double pole single throw switch with the 1HP 125V rating would work. Most that I have look at on line have a very similar switch body and would imagine would be able to mount in the existing opening of the control box.
That's my story.
