Plunger Switch
A plunger switch is used to monitor door state. When the door is closed it
comes into contact with the plunger which closes a circuit which turns the
light and display off. When the door is open the plunger moves outward and
opens the circuit. If the door is left open for longer than 5 minutes the switch
will trigger an error code and set an audiblewarning.
