Monitor Door Switch

I saw a similar problem description at partselect.com and was confident to take the challenge to repair it myself. (Thanks to partselect.com). When I opened the microwave cover I found 3 similar switches. 2 of them works the same way and the other in reverse direction. Image diagram provided to buy parts is helpful to identify the switch.
Steps:
Remove the built-in microwave from the wall and keep it in an open space.
Remove the microwave screws and take the cover out.
Remove the 2 screws(inside) from the plastic panel where switches are snapped in
Gently remove the faulty switch and replace with the new one.
(In my case the topmost secondary door switch was broken)

All electrical worked (fan, lights, control panel) door switch was broke. Pulled the oven out. Took out two big screws from the cabinet above. (be careful not to drop oven)Set the oven on kitchen counter. Took off five screws that held the vent cover. Removed vent cover. Took out one screw that held the control panel. Lifted, turned and slid the panel into the space below so I could get to the upper door switch. Replace door switch and re-assemble.

The switches are not the problem! The problem is in the tolerences of the latch housing. I have ordered two new housings (Upper & Lower) and will see if the tolerences are closer. If not I will try epoxying a shim to the plate that operates the microswitches. The other option is to file the mounting slots of the housing to allow adjustment, which would be iffy,keeping them from moving with use. The exploded drawings really need to be clarified. The scale is way too small. It was extremely difficult to pick out the individual parts of the mechanisiam.
