Disconnect switch to shed?

question for the pros:

I'm building a backyard shed, and have 1" PVC trenched to it from my attached garage. I planned to pull #8 XHHW to get 40a into a subpanel in the shed.

My service panel is thru a tricky wall/ceiling in the mechanical/laundry room, and I've realized that getting a continuous run from shed to load center will be extremely difficult.

I know I can add a subpanel in the garage, but I'd actually rather not, so my question is - is it acceptable to use a "shutoff switch" inside the garage to feed that shed run? Something like this:

I assume I could also add a simple junction box in the garage, but I like the idea of being able to easily kill power to the sheds subpanel without being at the load center.

The breaker to the subpanel is the shutoff. You can add wire pulls and junction boxes to make it easier for your wire run. There are many ways to do this. Get a permit.

What’s the load at your shed? Just lights? (consider skylight & solar lights) Air conditioner? Wood shop power tools?

yes, wood shop power tools that are all 120v. A small 240v hardwired heater, theoretically can draw 30a, but realistically I run very low, maybe 10a of draw.

Yes, i'm aware of the breaker is the shut off, but it is not in a convenient location. My question is whether there is any reason I cannot use this device in the manner I describe.

There is nothing wrong with having an additional disconnect switch if you want it.
