How to open this greenie

I got couple of those laser pointers.


I have to replace faulty switch bot dunno how to get out module from host.
Push, pull, what direction. I need a hand. I'm sure you did that before
Thanks, Mike

Use the google search... It looks like there are lots of threads for disassembling this host and the hardest part seems to be greeting the cap of without messing it up.
