Abstract
A door locking mechanism for an appliance provides a bolt that is biased by a spring but may be moved by a unidirectional actuator. A bi-stable mechanism blocks movement of the bolt at certain positions at successive actuations of the unidirectional actuator. In this way, energy need not be provided to the electromechanical actuator except periodically.
