Need help finding this type of lock

[Dave Mura]

I need to buy 5 of these, but can't find them anywhere nor do I know what they're called.
It's for a drawer, when you turn the key it pulls out and to lock it back you push it in.
Any help would be greatly appreciated!

I think you are looking for a plunge lock.

I think that's a Timberline lock.
