KW3AT Microwave Oven Door Switch, 4 Normally Open 2 Normally Closes

KW3AT-16 Microwave Door Switch Repair Kit When your microwave acts up, it’s rarely the motor or the magnetron—90% of the time, it's a burnt-out door interlock switch. Instead of buying an entirely new appliance, fix it yourself with the Weasch KW3A Microwave Switch 6-Pack Why Do You Need Both NO and NC Switches? Most microwaves use a 3-switch safety system in the door latch to prevent microwave radiation leakage: Normally Open (NO) Switches: Used as the Primary and Secondary interlocks. The circuit connects only when the door is closed (pressing the button).Normally Closed (NC) Switches: Used as the Monitor switch. The circuit connects when the door is open (button released) to short out the system and blow the fuse if the other switches fail.Our Kit: Includes 4x NO (KW3AT-16T0) and 2x NC (KW3AT-16D0) switches. This is enough to completely overhaul TWO microwaves.Technical Specifications:Model: KW3AT-16T0-B200 (NO) / KW3AT-16D0-B200 (NC)Electrical Rating: 16A 125/250VACOperating Force: 2N (Approx. 200gf)Contact Configuration: SPST-NO (Normally Open) & SPST-NC (Normally Closed)Lifespan: 50,000 Electrical Cycles / 2,000,000 Mechanical Cycles
