ABSTRACT:
A door latch is provided for the access door of an appliance. The door latch apparatus includes bracketry for mounting at least one switch and actuating levers. The movable access door includes a catch which is engageable with one of the actuating levers as the access door is closed for sensing if the access door is in a lockable posture. Another actuating lever is pivotally operated by a solenoid actuator under control of a microcontroller-based controller to position one end of the lever into locking engagement with the access door catch and to actuate a switch for providing a signal to the controller that the access door is closed and locked.
