Switches usually open after closing, so your latch arrangement has to figure out how to unlatch.
At which point you are doing debouncing: distinguishing an intentional switch opening from the bounce that continued after you latched. You need some hold-off time or something.
Also, switches contacts bounce when opening!
A latch could be great for some kind of panic button which indicates a state change that continues to be asserted when the switch opens (and is reset in some other way).
