Product review (5 stars): Drops in place and fits like new!
Drops right in place. I had broken the original by pulling up too hard to see what was underneath. There are some Youtube videos showing you having to under and reset a switch and insure the base snaps in. In my case I was able to drop it in place, push down a little and it 'popped' in place.  You can hear and see the switch being pulled up as a quick test.
