I'd say snap. The main thing is the hole in the middle and the overall length. PM you address and I send you the 240v one unless you got sorted.
@Chris F - did you ever get this sorted? I just pulled a working 152ADS off my lathe, if that would help?
Nah not yet. Haven't gotten round to trying a totally different starter yet.. hoping to do so shortly. Got a photo of your 152ADS? Cheers!
Ah shame - just sold it Pics of it here, if they are of any help: Olde worlde electrical switches | MIG Welding Forum (mig-welding.co.uk)
