My dyson dc17 won't turn on and stay on unless you hold the red button on?

But how do you reassemble the part up top where the actually red button is. I accessed the power button t hat way and I did unstick the button but I can't figure out how to get the power button back on correctly. There is a small white piece and a short, fat spring that I can't seem to put back correctly. But how do you reassemble the part up top where the actually red button is.

Yes, in response to Heather, be careful to not let that assembly (the power button and its mate) come apart. Take a picture of it (I wish I had) as it will hold together for a while but eventually falls apart if you let the buttons rise too high. It took some time to get the white piece and the fat spring back in place, and it is not obvious how the parts fit together even though I had eye-balled how it was set-up. My original problem was it was stuck in the mode where it came on automatically when you began vacuuming (seemingly the mate button to the power button was permanently depressed), but would not switch the suction to the wand when the wand was deployed. The surprise disassembly and subsequent reassembly of the buttons, along with making sure both square red switches (one is shown in the second pic b/w the thumb and index finger) fixed the problem.
