I have a blower for the kids bouncing house and the switch wasn't working, by not working I mean was in the always on and never turned off the motor. So I took the switch housing apart and encountered a wiring setup I don't understand. Before I took the wire nuts off to test the switch I wrote down the diagram as it was when I opened the switch housing (see below)

First thing first: I tested the switch independently of the motor/black box with the continuity tester of my volt meter and found that the switch is working like expected.


Questions:

1) What is the black box for? Is it a phase swifter? Does that make this a 220 motor?

2) I think that the blue wire from the motor is the neutral shared by the two brown wires, is that correct?

3) How do I test (with my volt meter) that the black box is working correctly?

4) Is this wired right? I would expect to break the current for both brown leads to the motor with the switch, however the way it was wired this is not happening, is this why the switch doesn’t stop the motor?

Thanks in Advance,
Wayne

I am having trouble figuring out how to post the wiring diagram, so I am attaching it here.
