/diy/ - Do It Yourself

I've had an idea to try making a decorative plug as part of a construction project. ideally, the hatch would have a small know like a drawer pull linked to a dual latch system (1) to secure the plug to the cavity. The face diagram (2) would be the finished plug housing the internal mechanism. The cavity itself (3) would have a cutout to hold the latches, of course. I'm by no means a professional, so I may be over complicating the design unnecessarily.

My questions are these:
1. Are there dual cam systems available to further simply the latch mechanism? If so, what would they be called? If not, would it be possible to lay two cams in opposite facing for a similar action?

2. Are there any adjustments one could make to either simplify construction or make it more asthetically pleasing?

Thanks in advance, and apologies for the poor diagrams.
