What is the feature called in new made garbage disposer have now a days, which turns on only when you put a cap or a cover kind of thing on the kitchen sink. Not the old fashion way which is unsecure too to have a switch to turn on... which grind even your hand... I am in market to buy one but don't know what that feature called.

I think they are called "batch feed".

And you'd be correct Flossie!
