Shark rotator lift away and wand button assembly is disassembled.

I purchased vacumn from a garage sale for $5! The husband had taken it apart and couldn't reassemble it. I have it mostly all back together, Powers up and works. The one thing I have been unable to figure out are the buttons for the lift away & wand. The assembly is a tube , a stick and the buttons along with several springs. Need to know assembly order. Would love to see a picture or diagram if what it is supposed to look like put together. Can anyone help?
