Showing hidden/xray details not wanted

My model is showing X-ray details that i can’t work out how to turn off!

Please see pictures below.

The first show the view with hidden/X-ray details I don’t want displayed.

The second shows the components earlier in the construction of the model as I would like the displayed.

How do get rid of this detail from my model.

Tap k, it is the toggle for back edges.


Components without Xray/hidden lines

Many thanks.
