Thanks everyone for the replies. It may well be Klockner Mueller. I will look in a few minutes. As to what windings, Well, the motor has two sets of connections {u,v,w} ands {x,y,z), so I am assuming that the switch takes the incoming 3 phase and switches it to either of these two sets, or to nowhere for the off position.
This all started when I accidentally pinched the armored cable to the head of my Rambaudi. It was a little too long and flopped in the way. I was pretty intent on what the cutter was doing, and didn't notice it. It wound up shorting out a wire and breaking the casing.
I replaced the whole thing with flexible conduit.
But when I was removing this Mueller switch to do that, it fell apart.It is a modular thing andthe end cap came off allowing all the guts to come out, including all the little red cams.
I don't believe I can put it all back together again, it might have used special jigs at the factory. I also blew out one of the fuses. It sits in a wierd ceramic fuse holder. When one of these fuses go, a little pice of metal pops forward, which you can see through a clear part of the screw-in capwhich holds the fuse. Anyone have any idea where I can get these??
