Understanding Normally Open vs. Normally Closed
Normally Open (NO): The electrical contacts are open (circuit inactive) when the switch is at rest. Pressing the switch closes the circuit and activates the connected function. In a microwave door, this means the appliance activates only when the door is shut and the switch is engaged.
Normally Closed (NC): The electrical contacts are closed (circuit active) when the switch is at rest. Pressing the switch opens the circuit and deactivates the connected function. This is the opposite behavior of a normally open switch and is commonly used as a safety interlock that cuts power when the door is opened.
Why Replace Your Microwave Door Switch?
The door interlock switch is one of the most commonly replaced parts in a microwave oven. A faulty switch can cause the appliance to stop working entirely, run with the door open (a safety hazard), or behave erratically. Replacing a worn switch with a quality KW16-series part restores normal, safe operation quickly and affordably.

Frequently Asked Questions
Q: Are these KW16 micro switches compatible with my microwave oven?
A: The KW16(5)A 250VAC micro switch is a widely used standard size compatible with many common microwave oven brands and models. We recommend checking your existing switch's model number and ratings (voltage and amperage) before purchasing to confirm compatibility. The KW16 form factor is one of the most frequently used door interlock switch sizes in household microwaves.
Q: What is the difference between a normally open and normally closed microwave door switch?
A: A normally open (NO) switch has an open circuit at rest and closes when pressed — it activates the microwave when the door is shut. A normally closed (NC) switch has a closed circuit at rest and opens when pressed — it cuts power as a safety interlock when the door is opened. Most microwaves use a combination of both types in their door interlock system.
Q: How do I know if my microwave door interlock switch needs replacing?
A: Common signs include the microwave not starting at all, the interior light not turning on, the microwave stopping mid-cycle, or the turntable not spinning. A failed door switch is one of the most frequent causes of these issues. Always unplug the microwave before inspecting or replacing any internal components.
Q: How many switches are included in this package?
A: This listing includes 2 micro switches per package — ideal for replacing multiple switches in your microwave door interlock assembly at the same time.
