Normally Open Switch problem

Ok so I’ve been dealing with a microwave where the normally open switch keeps fusing together and triggering the breaker when pulling the door open. So I’ve been tinkering with the switch each time and “unfusing” it when it does that. Most of the time after “fixing” it the wife just presses off before opening it to prevent the switch fusing together and that’s works. Except for the rare times we forget and pull the door open while running and it does it again. I bought another switch from amazon and thought ok I’ll pull the door open and see if the new switch does it. It did and fused together again. So not I’m back at square one. I have another new switch that I’m going to put in and we will just press off while I find another fix. However I thought if the switch is normally open while running, then will it work without that normally open switch so I put everything back together without that switch and it works. I even pulled the door to find out if the microwave would stay on and it turned off and works like normal. So my question is can I just leave it that way??
