Bosch Microwave HBC84H500 Parts

This is a micro switch used in the microwave door interlock system. It detects whether the door is properly closed and signals the control board to allow or prevent microwave operation. Replace this switch if the microwave won't start, runs with the door open, or if the door latch clicks but the unit doesn't respond.
