This has got to be a loaded question...

Are you trying to use it independently of it's associated equipment?
I’m not sure if I understand your question.
The fan/motor will be 2nd floor and the shop is 1st floor. My customer wants to have some kind of switch type to operate on/off

Okay, how about a 2p HP-rated switch?
Yea motor rated switch, I was wondering to know how it practically wired. My Question was about does the switch wire direct to the motor?

Two conductors down to the switch then back up to the motor? You could get fancier and use a contactor at the motor, 24V coil, small 24V transformer and two conductor low voltage wire down to a single pole switch.

I see. Yes The motor comes with transformer. It has 24V output to feed PWM controller. So I can use the 24V to feed the switch
Unless the controller and it's disconnect are in sight from the motor or the motor is cord and plug,, 430.102(B) requires a disconnect in sight from the motor.
The disconnect would be required to open the power circuit so a 2 pole switch as listed in 430.109(C)
If the "in sight from motor" is covered and you are wanting to control it from the 1st floor it sounds as if you could you a switch on the 24v circuit.
