Re: Keith Blackman motor wiring
It looks like it might have had a contactor with two coils with a latching one on the (R)un terminal and a non latching coil on the (S)tart terminal.
You just push the start button and both windings are connected until you let the button go.
It just blows the fuse if you hold the button for too long.
Control gear was simple in old times.
