How to keep parts from merging into one another in assembly?

Hey SW Community!

So I have this handle on a box and I want to know how I can keep the handle from merging with the box when I rotate the handle around...

Right now, the handle has 360 degrees of rotation so it "glitches" into the box instead of stopping on the face like in real life...

Any ideas?

Thanks!
