machine switch

[sue denim]

Hello

I am still having problems with the switch on my myford ml8 lathe. apparently it is a two stage switch and my electrician said that they can be bought off the shelf ready to fit. Trouble is I can't find one .

Any help gratefully received

Regards Sue

These are all good links , thanks.

A question or two

The switch is a two stage thingy and you can here the second switch kick in after the initial push button start. Will these cope with that requirement ?.

I like the reversible switch but I am concerned that the threading on the lathe will allow the work piece to be turned off the machine!.

Sorry to be a pain but I know zero about machine electrics.

Regards Sue

i believe the 2 stage bit is a safety feature, to either a) stop an accidental and immediate 'on' or b) deliver the electric to the motor in two stages so as not to overload the supply.

I think i read somewhere that it was MEM switchgear on myford lathes? if so is there a part number on yours? MEM eaton are still a going concern see here...http://www.eaton.com/EatonCom/ProductsS ... d=EatonCom
and could be worth a call or email asking what the modern equivalent would be.
they have a product info guide here...

at a guess i would say you would need something like this...http://www.tlc-direct.co.uk/Products/MM28ADS1X.html

i must stress i am not a qualified electrician or machine engineer, maybe you could print out the specs and ask your local sparks if its the right type of thing.
or if anyone else on the forum knows better, please correct me, i wont take any offence
