Magnetic record switch

Here's what I came up with to stop and start recording underwater. The magnets came from Jaycar, a magnetic handy strip for less than $15. This plastic hanging strip contains about 8 magnets encased in a long plastic strip which can be cut to length.

An external magnet attracts the internal magnet operating the right angled lever. More photos here.
Works like a charm, if everything lines up properly.

The camera beeps to let me know if it's starting or stopping record mode.
