A micro switch, also known as a miniature snap action switch, is used in ovens and microwaves. This is used to change the direction of power, from on to off. The switch uses a spring to open and close the connections inside of it. This part should quickly switch power direction, but if your switch is defective, damaged, or broken, it will not work properly. In this case, it is best to replace the switch. Make sure to unplug your appliance from the power source before beginning this installation project. Refer to the manual provided by the manufacturer for further installation instructions and guidance.
