Why are microwaves so picky about the way they do their door switches? Are two different interlock switches really necessary? And what does the monitor switch even do, anyway? All these questions and more answered in this short instructional presentation.

Big props to Brother @Vance R for his explanation of these switches in this topic, which inspired us to make this video.

Topics covered include:

• Schematic analysis of interlock switch circuits
• Identifying if the schematic is drawn with the door open or closed
• NO and NC switch terminals
• The purpose of a microwave monitor switch
