Correct middle position all off
Yes your professional diagram is the same as to what my rudimentary diagram tested out to be.
You did read post 25 from Ken as to how the switch I have rung out?Hi, have a look at the switching diagram that I sent. This is the internal switching of your switch without the links.
You will have to link the correct terminals together to make it reverse the motor.
I am at work at the moment but if I have some spare time I will draw out the wiring diagram for you otherwise I will do it when I get home.
