Re: Ferrograph 4A: Restoration advice needed
Hi Uncle B,
There appears to be a loop of wire and moving contact missing from your auto stop. It is designed to make contact with the fixed contact on the bakelite body of the switch. The moving contact must be insulated from the peg and spring and that is why there is a sleeve over the peg.
Here is the arrangement on a Series 4 Vortexion, the sleeve on this one is black plastic. Watch out though, these contacts are all at HT voltage on these models!
Hope this helps,
Bill
