I'm trying to determine if a disconnect switch (in this case a single pole switch) meets code at a job site I visited last week. I know overcurrent devices need to be readily accessible, but can't find a reference that says the d/c switches have to be as well. I know it is common sense that they should be, however can't remember where it is in the code.

Thanks!

What is this disconnect switch disconnecting?

A unit heater... which in this case is basically just a motor for the fan (heat comes from the hot water).
 
So 430.102 - it only has to be within site of the motor, even if it is nearly impossible to get to?
 
Yep. The purpose of the disconnect is not to provide a means of turning off the motor in an emergency. Its purpose is to allow the maintenance person to know that nobody is going to turn the motor on while work is in progress. You can see the disconnect, while your hands are inside the motor, so you know it is still open. That's the idea.

I agree, you will see then above suspended ceilings and on top of bathrooms and many other strange places.
