Not sure what function the switch uses, but I'll take some guesses and you can try them out to see what is correct.

First of all, turn the switch off and then see how close you can focus to an object when fully zoomed out. Next, turn the switch on and see if you can focus closer. That's typically all "Macro" means on a zoom lens, the ability to close focus while zoomed out.

The other possibility is that it might be a focus limiter, meaning it restricts the AF movement to something close to the lens, and prevents it from focusing all the way out to infinity (something you'd rarely do if you were shooting macro).

Either one of these possibilities should be easy to test. Let us know what you learn.

I've got the same lens. The macro switch is a bit weird to get used to.

To switch from normal > macro you must be zoomed between 180-300 (there's a gold line there). Once that is engaged, you can focus even closer, as indicated on the focus ring by the numbers with a gold line under them.

To move the macro switch back to normal, you have to turn the focus ring (remember to disengage AF! no quick shift here) past 1.5m/4.9 ft and then you'll be able to move the switch.

Exactly..

Taken at 180mm



Taken at 300mm



Neither image is cropped.

Enjoy your new lens.

It allows you to focus closer.

it didnt come with instructions. used from ebay.

so can you use macro if you are zoomed into 300 and trying to focus on a bird really far away? or is it used more fr zooming in to an object close to you?

Either / Or. The 300mm photo I show was taken standing at about 4 feet from the bolt as was the 180mm.

Macro mode allows the lens to decrease the minimum focus distance. Think of it as reading glasses for old eyes. No more holding the book at arms length, bring it in close and see it big.
