Beschreibung
Zusammenfassung:	An actuator assembly includes an operating actuator and a holding actuator that are engageable with an operator member of a device. The operating actuation is cycled between on and off states to move the operator member in incremental steps, and the holding actuator is maintained in an active state to maintain or latch the current position of the operator member. Each of the operating and holding actuators may include one of the following: a solenoid actuator; and an actuator including one or more expandable elements, such as a piezoelectric element, a magnetostrictive element, and a heat-expandable element.
