2007 Camry cruise control switch replacement

[ghunt]

My girlfriend and I were riding in her 2007 Camry SE about a week ago on the highway. She pushed the button on the cruise control switch to turn it on, and the button popped out of the end of the stalk (it did not completely come out, but popped out about an inch). She pushed it back in, but it won't turn the cruise on now.

What all is involved in replacing this switch? I was assuming it was as simple as removing the bottom rear cover on the steering wheel and swapping it out, but I wanted to check beforehand.
