Re: Still looking for an electronic lock...

Since most similar locks do the opposite (fail open on power failure for fire escape reasons)...

All you need is any type of latch, and a magnetically controlled striker plate. The latch could be a cylinder rim night latch (often called a yale lock) or a regular door catch with no outside handle.

If the striker is configured to lock when not powered, then the latch will work just as though there is a fixed striker - just like a normal door latch. When electrically released, the flat can be pushed open allowing the latch to pass.
