I've decided to use an all steel constructed "touch touch" latch on both my drawers and cupboards. Just a touch to open and a touch to close. I suppose they could open in the event of an accident if the contents they secure were to violently toss about but for normal conditions they should work just fine--unless they jamb
See National Tutch Latch on Google or ebay. BTW, My entire 70 year old house was equipped with these when it was built and they still all work. Hope this helps.
