You're right about the endless number of different switches, there also seems to be an endless number of people confused by how to wire them
-M
ps in this 3 wire configuration moving T8 from one line wire to the other gives the reversing function, and the start leg only sees 120 volts since it connects to the midpoint of the two run windings
pss you can swap T8 and T5 if the motor rotation is backwards from the switch handle
Yup, that's me. Just throw in a Chinese equipment manual to help.
Figured about the T5-T8 swap. Somewhere in this stack of hand-drawn schematics piled up on the floor I have/had one that looked something like that, but not quite. I ran that one by the local electric motor guy who said it wouldn't work-'you need the five wires'. My drawing wasn't clear and he was busy so I didn't pursue it.
What year 633?
