Abstract
An electrically operable door latch employs a permanent magnet for retaining an appliance door closed against the force of a resilient seal. An electromagnet bucks the magnetic attraction of the permanent magnet allowing the latch to be electronically releasable. A simple mechanism and inherent force limits are obtained by a direct magnetic attraction between a strike plate and the latch, one on the door and one on the housing.
