Hi

I previously posted a switch which I thought to be a santon I was wrong it is a Diamond H switch so I am hoping someone out there can help me with a wiring diagram to connect it with a Crompton Parkinson motor with terminals A, Z, AZ & T,

I am not familiar with your make of switch, but if you form a truth table of open and closed pairs of terminal then you are part the way there. zero and one, open/closed . Mark each terminal some way or other dobs of paint or coloured nail varnish. With an ohmmeter or a buzzer continuity tester you can sort it out. The switch is 4 positons type so you are looking for vertical OFF, left forward and to the right reverse, I know its easier with a bit of experience. There looks to be sufficient number of terminals and once you have it sorted then follow the Dewhirst/Myford wiring arrangement. One thing I would like to point out ,that the switch on its own doesn't give any No-Volt release which is a good safety feature, a proper motor starter fitted with RED and GREEN pushes do.John

Further to John's reply, those black links look like a give a way, could be L & N inputs. If they are, then they feed the motor via a reversing action to one winding.
