Re: Older stuff WAS simplier...
On most microwaves I've seen, the door is attached to a switch. You still have a standard hinge and handle to pull open, but if you do that the microwave immediately turns off. It won't let you start it unless the door is closed. So as long as the door keeps itself shut, radiation shouldn't be a problem. That said, I don't really have anything against a specific control for opening the door, as it at least serves a purpose, unlike the many buttons I have on my microwave and have never actually used.
