Can anyone point me in the direction of buying a new cam switch at all - 32a 690v 6 position , only one I can see is from Ali express but will take a million years to get here Thanks in advance
https://technicalarc.co.uk/ there catalog can be downloaded from the top of the page (to big to post here)
There may be a manufacturer name and part number printed on that label on the switch. This is Tec-Arc: https://www.ebay.co.uk/itm/6-POSITION-SINGLE-POLE-VOLTAGE-SWITCH-FOR-MIG-WELDER/113731613287
As you said, the YMZ12 part number leads to Aliexpress, only. From my post #3 in this thread https://www.mig-welding.co.uk/forum/threads/sealy-supermig-250-10.104133/#post-1643033 these guys: https://www.davron.co.uk/Comp1.html https://www.davron.co.uk/BremasM.html seem to know something about cam switches, and may be able to supply an equivalent.
Took old switch apart to see and learn - and the rocker had split and the grove it sits in one side had come away - take it this is being heavy handed and turning it to fast maybe
